Graphite Chill

Graphite cold iron is used in the foundry industry, with carbon content greater than 98.5%, density greater than 1.6g/cm3, specific resistance less than 9, compressive strength greater than 24Mpa, flexural strength greater than 14Mpa, ash content less than 0.5%, graphite carbon cold iron material It has the advantages of light specific gravity, high refractoriness and high thermal conductivity. The use of graphite chilled iron as the chilling material to replace the metallic chilled iron is a new casting process that has been summed up and promoted by foundry experts after years of practice. It can better solve the problem of porosity and shrinkage of cast steel, cast iron, cast copper and cast aluminum parts, and can effectively solve the casting defects such as white mouth and pores caused by improper use of cast iron cold iron.
