In the smelting process of iron and steel products, due to factors such as smelting time, holding time, and longer overheating time, the smelting loss of carbon in the molten iron increases, resulting in a decrease in the carbon content in the molten iron, leading to The carbon content in molten iron does not reach the theoretical value expected for refining. The carbon-containing substances added in order to make up for the carbon content lost during the steel smelting process are called rec...
It has high thermal conductivity and the performance is stable at high temperatures, thus maintaining good performance even in use process under high temperature. The thermal expansion coefficient of a graphite crucible is very small, and the effect on the performance of the crucible is also very small in the case of shock cooling and shock heating. The graphite crucible has superior performance in smelting alloy tool steel, nonferrous metals and other alloys, so it is widely used in metallur...
Fine grain graphite rod material is made of high quality calcined petroleum coke and modified coal asphalt through the specific process formula and thermal process, but the
