The Characteristics Of High-quality Graphite Crucible

Graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the thermal expansion coefficient is small, and it has certain strain resistance to rapid heating and rapid cooling. It has strong corrosion resistance to acid and alkaline solution and has excellent chemical stability.
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 a good technical and economic effect.
The production technology level of domestic graphite crucibles has reached or even surpassed that of imported crucibles. High-quality domestic crucibles have the following characteristics:
1. The high density of the graphite crucible makes the crucible have the best thermal conductivity, and its thermal conductivity is obviously better than other imported crucibles;
2. The exterior of the graphite crucible has a special 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 made of natural graphite, which has very good thermal conductivity. Do not place the graphite crucible on a cold metal table immediately after heating to avoid it from cracking due to rapid cooling. Crucibles are most suitable for melting alloys of various types and small quantities. If you want to change the type of alloy, you only need to change the graphite crucible. Other melting methods, such as reverberatory furnace and non-crucible induction furnace, are suitable for melting a large amount of single alloy. If the type of molten alloy is changed, if the refractory lining is not replaced, metal pollution will occur.
There are many types and specifications of the crucible, and it is not limited by the production scale, batch size and the variety of smelted substances when it is applied. It can be selected arbitrarily, has strong applicability, and can guarantee the purity of the smelted substance.
