Gray casting iron and other metal materials are often using as densener in casting. While, these material has small conductivity coefficiency(2.0 , 2.5 kcal / m. Hours. Degrees),which has caused the problem that external casting has solidified, and the interior is also in liquid state. Although later on the interior will cool down and become solid, it often causes the defects of depression and inner surface texture loose because of the interior volume shrinkage when cooling and solidifying.


Graphite cold iron can improve casting cooling both internal and external as soon as possible and at the same time.

Graphite cold iron can absorb more heat in a short period of time because of its large thermal conductivity and enhance internal and external casting cooling as soon as possible.


All these advantages have solved the problems of loose texture of hot-section parts, shrinkage problems, and casting microstructure of thin flaky pearlite is more than 95%; the number of eutectic is up to 450-550cm. The casting hardness can increase 20-50HB, and improves casting surface finishing and abration endurable resistance.


2,Graphite cold-iron is easy to operate.


Because of a small proportion of graphite cold iron, about 1/5 of cold iron metal, it is easy to carrying, sand mould (core) is not easy to drop off when repaking 3,Graphite cold iron is re-usable with low cost. As the cold graphite iron refractoriness can be up to 2800 degrees Centigrade and its high temperature resistance, it is not easily oxidized performance and avoids casting defects as casting produces white (cementite) and porosity. The surface of cold iron materials is not easy to be burnt, oxidation, cracking, and operation life is 5 to 10 times longer than cast iron and other metal materials.
