Coal powder. Coal, referred to as coal, is the ancient plant remains, buried in the ground, through the earth's crust to isolate the air pressure and temperature conditions, resulting in the carbonation of fossil minerals, mainly used as a fuel for human. Coal for industrial modernization, whether it is heavy industry, light industry; both the energy industry, metallurgy industry, chemical industry, machinery industry, or textile industry, food industry, transportation play an important role Coal powder characteristics Compared with ordinary pulverized coal, coal powder produced by our plant has the following advantages: 1, bright carbon value, volatile and char residue high characteristic, ash content, low gas, a wide range of gas temperature, anti sticking sand and anti clip sand ability etc. advantages. 2, add a little amount, can reduce the sand clay content and water content, sand and new supplement and bentonite usage and improve the sand permeability, mobility and flexibility, especially to prevent casting of sticky sand, sand inclusion, blowhole defect have unique effect. Physical and chemical index Product Name Quantity of heat Volatile parts Sour ash content Water content Fixed carbon coal About 6000-8000 calories About 10% About 0.3 About 8 About 6 More than 70% Mechanism of coal dust preventing sand sticking 1, in molten metal under the action of high temperature mold surface of pulverized coal produced a large reduction of the gas, to prevent oxidation of the molten iron, and iron on the surface of iron oxide reduction, reduction of metal oxides and sand the possibility of chemical reaction. In the cavity, the reducing gas mainly comes from the volatile matter of coal powder 2, after the heating of coal began to soften, with plasticity. If by the beginning of softening to curing between relatively wide temperature range and time long, buffer quartz grains in the heat, the temperature interval and the formation of expansion stress, which can reduce the casting defects caused by thermal expansion of the sand. 3, the pulverized coal after heated gas, liquid and solid three-phase colloid, colloid volume expansion part jam pore between grains, molten iron is difficult to penetrate. 4, pulverized coal in the heat generated by the carbon hydride (mainly aromatic volatile points in 650 DEG to 100 DEG C high temperature, in a reducing atmosphere in the occurrence of gas phase pyrolysis and on the interface of the liquid metal and mold precipitation layer with fine crystalline carbon luster, known as lustrous carbon.
