Industrial Gas Crucible Furnace Occupies a Small Area
Crucible furnace is one of the simplest melting equipment, which is mainly used for non-ferrous metals with low melting point, such as copper, aluminum and their alloys. In the furnace, the alloy is melted in the crucible, and the heat enters the furnace through the crucible, and the furnace is not in direct contact with the combustion products. Therefore, the chemical composition of the alloy is hardly affected by the furnace gas, and the temperature of the alloy liquid is uniform, which is its main advantage. Its disadvantage is low thermal efficiency, high fuel consumption and small crucible capacity, Poor working conditions.
Crucible furnace has always been the equipment for smelting copper alloy. Now, crucible furnace is used for smelting copper alloy in a large proportion. In ancient times, charcoal was used as the heat source for smelting, but now it is followed by heavy oil, gas, electricity and coke. Recently, in order to save energy and protect the environment and improve efficiency, some heat sources have been changed from heavy oil to gas and some to induction furnace.
The application is not limited by the production scale, batch size and variety of smelting materials. It can be selected arbitrarily, has strong applicability, and can ensure the purity of the melted materials. Due to the above excellent properties, graphite crucible furnace is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical industry and other industrial departments, and has good technical and economic effects,
Crucible is an important part of induction furnace. It is the basis for realizing the transformation of induction heating capacity and metal smelting torch.
The function of crucible is shown in the following points:
1. Crucible is an important medium for effective energy transmission of induction coil liquid, which not only ensures the conversion of electromagnetic field energy into heat energy and the basic condition for metal smelting, but also plays an important role in insulation between induction line and molten steel and molten steel.
2. The crucible bears various thermal stresses such as gravity or molten steel.
