In national economic production, graphite crucibles are widely used. Everyone knows the crucible, but what is a graphite crucible? Now, Henan Liugong Graphite Co., Ltd. will introduce to you the specific meaning of graphite crucible, special high-purity graphite crucible for metallurgical industry, and smelting graphite crucible:

Coke graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the thermal expansion coefficient is small, and it has strain resistance to rapid heating and rapid cooling. It has strong resistance to acid and alkaline solutions and has excellent chemical stability. In metallurgy, casting, machinery, chemical industry and other industrial sectors, it is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys. And has better technical and economic effects.

Coke-graphite crucibles are widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical and other industrial sectors because of the above excellent properties. And has better technical and economic effects.

The production technology level of domestic coke graphite crucibles has reached or even exceeded imported crucibles. Domestic crucibles have the following characteristics:

1. The high density of the coke-graphite crucible makes the crucible have excellent thermal conductivity, and its thermal conductivity is obviously better than other imported crucibles;
2. There is a glaze layer and dense molding material on the surface of the coke graphite crucible, which greatly improves the corrosion resistance of the product and prolongs its service life;
3. The graphite components in the coke graphite crucible are all made of coke, and the thermal conductivity is very good. After the coke graphite crucible is heated, it should not be placed on a cold metal table immediately to avoid it breaking due to rapid cooling.

The melting of many kinds of alloys in small quantities is very suitable for the use of crucibles. To change the type of alloy, it is only necessary to exchange the coke graphite crucible. Other melting methods, such as reverberatory furnaces and non-crucible induction furnaces, are suitable for mass melting of a single alloy. If the type of melting alloy is changed, metal contamination will occur if the refractory lining is not replaced.
