Now in our metallurgical industry, high purity graphite crucible has a very wide range of uses, the main role is to release all kinds of liquid metal, so what is so important when we use graphite crucible need our attention?
1. High-purity graphite crucible is easy to be damp. After damp, the product will become soft. It will encounter the situation that some impacting objects will be struck and deformed. Once water enters the high-purity graphite crucible, it will affect the raw materials in it. It will cause the dilution of raw materials, and some chemical reactions will further affect its quality. Therefore, waterproof measures are taken. We must do it well.
2. Although the high purity graphite crucible is very good in quality and not easy to be damaged, it should be handled lightly. The falling or bumping at high altitude has little effect on the quality of the graphite crucible, but cracks will occur if it goes on like this for a long time. There is no remedy for this situation and it can only be replaced.
3. High purity graphite crucible should not be heated over open fire. Because its heat conductivity is not particularly sufficient, heating on it is meaningless, and using smoke and fire or blackening on its underside is very beautiful. Because of its good thermal conductivity and high temperature resistance, high purity graphite crucible has low thermal expansion coefficient, strain resistance to rapid heat and quench, strong corrosion resistance to acid and alkaline solvents and good chemical stability. High purity graphite crucible is widely used in smelting various non-ferrous metals such as silver, aluminium, lead, copper, zinc, medium carbon steel and rare metals. High purity graphite crucible has stable quality, long service life, greatly reduced fuel consumption, reduced labor intensity, increased labor intensity, and created better economic benefits.
