Lico graphite crucible has good thermal conductivity and high temperature resistance. In the process of 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.

Like 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 graphite crucibles has reached or even exceeded imported crucibles. The domestic crucibles have the following characteristics:

1. The high density of graphite crucible makes the crucible have excellent thermal conductivity, and its thermal conductivity is obviously better than other imported crucibles;
2. The surface of the graphite crucible has a glaze layer and dense molding materials, which greatly improves the corrosion resistance of the product and prolongs its service life.
3. The graphite components in the graphite crucible are all graphite, and the thermal conductivity is very good. After the 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, just exchange the 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.
