How does annealing furnace work?

The melting furnace is used to superheat the solid material until it dissolves. It is usually used to change the temperature of the internal surface of the device by raising the temperature. For metals, this usually increases toughness strength. This requires an industrial furnace capable of producing maintaining temperatures below the melting point of the material.

On the contrary, the soft landing temperature produced by the melting furnace exceeds the melting point of the metal, which leads to the physical structure decomposition liquefaction. The transition thus depends on temperature pressure. In addition to mercury (Hg) known eutectic gallium (GA) alloys, some metals can also exist in liquid metals at room temperature.

In order to obtain a uniform molten mixture, the melting furnace should be able to produce maintain the appropriate temperature for a period of time. There are several furnace architectures that can perform this process.

Cupola annealing furnace

Cupola is usually installed in the vertical heating chamber of the system filled with a layer of combustible materials such as coke limestone. The air inlet allows air to enter the combustion chamber for combustion, making it easier for the lower part of the dome to enter the working door. This is to reduce the melting mixing of raw materials, which can be extruded through the movable bottom groove regularly.

Annealing process tool for cupola in ferrous metal casting. The architecture is simple robust, but reliable exhaust emission control should be considered. In general, the top of the dome shaft will be covered by an innovative filter to remove particles the gaseous waste.

Induction furnace

Induction annealing furnace is suitable for different ball types. They use spiral heating elements embedded in the crucible integrated into the wall of the heating chamber itself. The conversion of electric energy to heat is realized by the thermal uniformity of matter radiation.

Limit the use of combustible fuel facilities to more reliable daily operators components, especially for conventional melting applications. The spiral winding induction coil is designed to heat metals ceramics in refractory materials to improve service life has good control compatibility. The thermal cycle can be automated additional control can be achieved to reduce the generation emission of toxic metal vapors melted in the furnace
