Cold graphite iron, the main principle of using graphite chill material with a light specific gravity, high refractoriness, large thermal conductivity, etc.So with graphite chill as chilling agent instead of cold iron metal materials, can well solve the cast steel, cast copper, cast aluminum castings such as osteoporosis, shrinkage problem.And can effectively solve by using metal cold iron castings produced by white, porosity and other casting defects.In the hot parts of the casting need to chill put cold forming of graphite iron, can make the casting microstructure is fine lamellar pearlite amount to 95% above, eutectic group number is 450-450 cm, 20 to 50 hb casting hardness can be improved, can improve the casting surface roughness and wear resistance.When using the graphite chill can besmear on the cold iron graphite coating or talcum powder coating, use 5 -- 10 times longer than the metal cold iron.
Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and etc.
