10 ton crucible furnace is safe and simple to operate. Gas crucible furnace

Crucible furnace has the advantages of simple structure, small investment and fast operation. It is widely used in the foundry workshops of small and medium-sized non-ferrous alloy processing plants and machine manufacturing plants. However, crucible furnace has low heat utilization rate, small output and poor working conditions, so large-scale production is no longer applicable.

Crucible furnace has always been the equipment for smelting copper alloy. At present, a large proportion of crucible furnaces are used for smelting copper alloys. The heat source of smelting was charcoal in ancient times, but now it is heavy oil, gas, electricity and coke. Recently, in order to save energy, protect the environment and improve efficiency, some heat sources have been changed from heavy oil to gas and some to induction furnace.

Crucible furnace When heating with electricity, the resistance heating element (resistance wire or silicon carbide rod) is arranged around the crucible, that is, the resistance crucible melting furnace Crucible furnace using fuel usually heats up rapidly, but its temperature control cannot be very strict The heating speed of resistance crucible furnace is slow, and the heating speed of electric heating wire can reach 900

Crcible furnace is the simplest smelting equipment. Now it is mainly used to melt non-ferrous metals with low melting point, such as copper, aluminum and their alloys. In this furnace, the alloy is melted in the crucible, and the heat is transferred to the charge through the crucible. The charge is a kind of combustion product.

The application scope of gas crucible melting furnace is applicable to the melting of non-ferrous metals and alloys with low melting point, such as aluminum, copper, zinc and tin, or used together with die casting machine. It can also be used for the heat treatment of molten metals and small steel parts. The fuel types of gas crucible melting furnace include city gas, liquefied gas (filling) and diesel oil.

In order to remove the water and other chemicals adsorbed by the crucible, otherwise water vapor will be generated during smelting and pouring due to the presence of water, resulting in the formation of pores. The newly built furnace usually needs to be dried for several days or weeks, otherwise the water and chemically combined hydrogen contained in the refractory cannot be released, resulting in the formation of pores during smelting.

Crucible furnace combustion system has many supporting models and specifications, which are not limited by 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.
