Oil-fired stoves are suspension-burning stoves that use heavy oil as fuel. It is generally composed of an oil burner, a noise port and a furnace cavity. The main components of an oil burner are the fuel nozzles and the register. The combustion process of oil is actually first atomized into small oil droplets, sprayed into the furnace cavity, https://www.vacfurnace.com/technology-frontiers/linear-optical-axis-vacuum-quenching/and the oil droplets are heated and evaporated and diffused and burned. The intensified combustion process is achieved by intensifying the atomization, evaporation and mixing of oil and gas with air. Oil-fired furnaces produce very little soot, but heavy hydrocarbons or carbon are solids that are difficult to burn and often leave the furnace cavity unfinished, forming thick black smoke. The combustion temperature of oil is generally 1300-1500 ?, https://www.vacfurnace.com/technology-frontiers/gear-vacuum-carbonitriding/and the amount of nitrogen oxides generated is much higher than that of coal-fired furnaces. Most of the sulfur in crude oil is concentrated in heavy oil, and oil-fired furnaces that use heavy oil as fuel should also pay attention to the prevention and control of SO2 pollution.https://www.vacfurnace.com/technology-frontiers/vacuum-heat-treatment-of-aerospace-aluminum-alloy-materials/

The holding furnace is a type of material surface that is ignited and burned at high temperature. After leaving the igniter, it is suddenly exposed to the atmosphere, resulting in rapid cooling of the red-hot material surface. Therefore, in the mineral composition of the surface sinter, the glassiness increases significantly. Strength drop, an instrument of this drawback, is an important part of the low pressure casting furnace.
It is composed of furnace body, molten pool, sealing cover and liquid riser, and is the basic part of low pressure casting machine.
There are many types of furnaces, such as coke ovens, gas furnaces, resistance furnaces, induction furnaces, etc. The advantages of this type of furnace are simple structure, convenient temperature control and good working conditions.https://www.vacfurnace.com/technology-frontiers/die-steel-vacuum-heat-treatment-news/ The power of the holding furnace can only make up for the total heat dissipation loss.https://www.vacfurnace.com/automotive-industry/c-c-composite-brake-material/
The molten pool of the electric reverberatory furnace is large. In order to improve the efficiency, there must be a large heating area, so the molten pool cannot be too deep. In order to facilitate the connection between the mold opening and closing frame and the holding furnace, and to facilitate the repair of the furnace,https://www.vacfurnace.com/technology-frontiers/surgical-instruments-stainless-steel-vacuum-heat-treatment/ a mobile frame can be used on the top-casting low-pressure casting machine, or the holding furnace can be designed as a mobile type. However, the heating elements of the mobile holding furnace are easily damaged by vibration and must be maintained.https://www.vacfurnace.com/technology-frontiers/vacuum-brazing-technology-of-static-guide-vane-ring/

The transparent electric furnace (transParentfurnace) uses the infrared reflective layer to reflect the radiation of the heat energy of the heating body to keep warm. At the same time,https://www.vacfurnace.com/technology-frontiers/gear-processing-technology-and-vacuum-heat-treatment/ the reflective layer can transmit visible light and be transparent. It abandons the traditional thermal insulation materials, and has the advantages of simple manufacturing process, small size, light weight, and high electric heating efficiency. Due to the special structure of the furnace body, the heat capacity is small,https://www.vacfurnace.com/technology-frontiers/vacuum-heat-treatment-of-ld-steel-hexagonal-cold-heading-die/the heating up is fast, and the cooling performance is good. The most striking thing is that the furnace body is transparent, and the workpiece in the furnace can be directly observed during use. https://www.vacfurnace.com/technology-frontiers/aerospace-materials-and-vacuum-heat-treatment/The equipment has a wide range of uses in scientific research and production in the fields of electronics and metallurgy.

If the workpiece is heated to a higher temperature and the aging treatment is carried out in a short time, it is called artificial aging treatment. If the workpiece is stored at room temperature or under natural conditions for a long time, the aging phenomenon occurs, which is called natural aging. Aging treatment.[url]https://www.vacfurnace.com/technology-frontiers/automotive-leaf-spring-vacuum-heat-treatment-news/
[/url] The purpose of aging treatment is to eliminate the internal stress of the workpiece, stabilize the structure and size, improve mechanical properties, etc. Aluminum aging found that the hardness of this alloy after quenching is not high, but after being placed at room temperature for a period of time, the hardness will increase significantly. The phenomenon came to be known as precipitation hardening.
This discovery has generated great interest in the engineering community. https://www.vacfurnace.com/technology-frontiers/aluminum-alloy-die-casting-mold-vacuum-heat-treatment-news/Subsequently, people successively discovered some aluminum alloys, copper alloys and iron-based alloys that can be strengthened by aging treatment, creating a new strengthening method that is fundamentally different from general steel quenching and strengthening - aging strengthening. During solution treatment, the heating temperature must be strictly controlled, so that the solute atoms can be dissolved into the solid solution to the maximum extent without melting the alloy. The allowable deviation of the heating temperature for solution treatment of many aluminum alloys is only about 5 °C. https://www.vacfurnace.com/technology-frontiers/four-stages-of-cemented-carbide-vacuum-sintering/
For artificial aging treatment, the heating temperature and holding time must be strictly controlled to obtain the ideal strengthening effect. In production, staged aging is sometimes used, that is, it is first kept at room temperature or a temperature slightly higher than room temperature for a period of time, and then kept at a higher temperature for a period of time. Doing so can sometimes get better results.
When maraging steel is quenched, microstructure transformation occurs and martensite is formed. Martensite is a supersaturated solid solution. This steel can also be strengthened by an aging treatment.https://www.vacfurnace.com/technology-frontiers/slender-shaft-vacuum-quenching-news/

Induction furnace is an electric furnace that uses the induction electrothermal effect of materials to heat or melt materials. The main components of the induction furnace are the inductor, the furnace body, the power supply, the capacitor and the control system.https://www.vacfurnace.com/technology-frontiers/the-function-and-the-production-of-ceramic-bulletproof-vest/
The main components of the induction furnace are the inductor, the furnace body, the power supply, the capacitor and the control system.https://www.vacfurnace.com/technology-frontiers/casting-vacuum-heat-treatment-process/
Under the action of the alternating electromagnetic field in the induction furnace, eddy current is generated inside the material to achieve the effect of heating or melting. Under the stirring action of this alternating magnetic field, the composition and temperature of the material in the furnace are relatively uniform, the forging heating temperature can reach 1250 ?, and the melting temperature can reach 1650 ?.https://www.vacfurnace.com/technology-frontiers/copper-wire-workshop-design-and-vacuum-heat-treatment/

Industrial furnaces often involve heating processes such as smelting, drying, baking, and chemical reactions in their production processes. The industrial furnace is the heating equipment used for these processes. The fuels that provide heat sources for these devices mainly include gaseous fuels, liquid fuels, solid fuels and electricity. The use of these heating equipment is prone to burns and electric shock accidents. If gas or liquid fuel is used, it may also constitute a fire and explosion hazard in the event of leakage or spillage.https://www.vacfurnace.com/technology-frontiers/vacuum-brazing-technology-of-stainless-steel-radiator-core/
When the industrial furnace is used, the furnace door lifting mechanism must be in good condition, and the broken wire of the wire rope must not exceed the specified value. The heavy hammer is properly configured, and the exposed transmission part should be provided with a protective cover. If it is a water-cooled furnace door, it is necessary to ensure that the pipeline is unblocked, and the pipeline is not frozen in winter. The furnace door should have a limit device. When entering and leaving the furnace, there should be an interlock device to cut off the power supply. The number of broken wires in the wire rope should not exceed 10% within the pitch. The weight suspension of the balance furnace door should be reliable. It is required that the protective device of the exposed transmission part should maintain the correct installation position and the structure is reasonable. The wire rope pulley of the furnace car should be intact. All pulleys and sprockets on the kiln are well-structured, free of defects, and rotate flexibly.https://www.vacfurnace.com/technology-frontiers/heat-treatment-of-dz4-alloy-in-high-pressure-gas-quenching-vacuum-furnace/
The furnace wall and furnace lining of the industrial furnace body should be tight and free of leakage. Refractory materials are required to withstand heat, corrosion, friction and chemical erosion, and the furnace wall of the furnace body must be kept intact without any defects; the gaps between refractory materials and their products must not leak air; at the same time, the integrity of the furnace must be strong. The gas valve should be able to make the switch stop at any position according to the operation requirements, especially to cut off the fuel supply quickly when the flame is extinguished. The air valve is required to be free from loosening and leakage to maintain its integrity and reliability. Oil pipes, air pipes and heating pipes should be free of cracks and leakage. Pipelines for various purposes should be kept free of leakage, cracks and smooth, the oil nozzle should be smooth, and the oil temperature and oil (air) pressure should be kept normal.https://www.vacfurnace.com/technology-frontiers/multipurpose-vacuum-processing-equipment/

We believe that radiation can kill cells in the body and have a certain impact on our health. Even some users worry about whether this kind of radiation will appear when buying a high-temperature aging test box, but it is not true.

When we use the high temperature aging test box, we should choose a regular brand, so that the upper and lower limits of the temperature can be set before the test. Once this temperature is exceeded, it will automatically stop and turn on the protection function to avoid the severe impact of the harsh environment on the sample. Of course, before testing, you should also check whether the sample contains flammable and explosive substances or substances that may cause strong corrosion.

What is a SIP Gateway

A SIP Gateway is a device that processes and transmits voice data from an analog device to a digital device. SIP gateways are used with legacy phone systems to enable IP-PRI and can come in two forms:

1.Physical devices
2.Software

If you’re using an older, on-premise PBX, it will use a physical SIP gateway to transmit an analog signal into a digital format. But if you’re using a program that supports voice and/or video data, chances are it’s using SIP gateway software to process your data.

VoIP Phone Systems - Create the Perfect Business Phone System

VoIP PBX

SIP intercom

You use your phone system (also known as a PBX) every day, so you already know that phone systems are responsible for handling your call control and managing your connection to your telephone service provider. What you might not be familiar with is VoIP.

VoIP is short for Voice over Internet Protocol. VoIP is a way to make calls across your Local Area Network (LAN) and or Wide Area Network (WAN). The technology behind VoIP converts your analog voice into digital packets which are then sent across a network using the Internet Protocol (IP) to their end destination. VoIP is most commonly associated with making calls across the Internet.

As you've probably guessed, a VoIP phone system gets connected to your LAN. It uses your LAN as the backbone of the system – connecting your VoIP phones and your VoIP service provider to the VoIP PBX. That makes a VoIP phone system a phone system that uses IP technology to handle your call control and manage your connection to the Wide Area Network over which your VoIP service comes.

Even though a VoIP phone system uses VoIP and is connected to your LAN most systems can connect directly to the Publicly Switched Telephone Network (PSTN). This gives you the ability to use both VoIP and the PSTN for your calling.
