Botou City, China are machinery factory, specializing in the production of high phosphorus grinding plate, grinding discs, grinding discs and grinding plate precision level: a board and 0 board, a board 0 board difference lies in the plane has a degree of difference between different grades; grinding plate, the situation of the use of the grinding plate, grind into dry research, and wetlands research, stem research, and wetlands research for the grinding plate and grinding disc requirements are different, dry research the requirements of the grinding plate is relatively high, the requirements of the workpiece after grinding scratches, the finish should be high, wet research on the grinding disk requirements are relatively low. Botou City China are machinery specializing in the production of high-grade, high-phosphorus grinding plate, ductile iron lapping plate, high phosphorus ductile iron grinding plate and so on. 
 (2) the characteristics of high-phosphorus grinding plate, ductile iron lapping plate: high phosphorus grinding plate, the mechanical properties of ductile iron lapping plate than gray cast iron plate and malleable cast iron, high tensile strength plastic toughness and the corresponding matrix organization cast steel plate similar. High phosphorus grinding plate, ductile iron lapping plate to both the advantages of cast iron plates and steel plates, which are widely used. It can replace carbon steel, alloy steel, malleable cast iron and other materials, made by the force, strength, hardness. Toughness and abrasion resistance requirements for milling cast iron plate. 
 (3) the production of high phosphorus grinding plate, ductile iron lapping plate contains the following links: liquid iron smelting qualified spheroidization treatment, inoculation, blast furnace inspection, pouring castings, cleaning and heat treatment, casting quality inspection. Melting quality of molten iron and the ball of inoculation is the key to production. The quality of the liquid iron is the key to obtain high quality ductile iron casting, the quality of molten iron for ductile iron production should be high-temperature, low sulfur and phosphorus content and low impurity content (such as oxygen and anti-ball of element content, etc.). Order to obtain low sulfur high temperature of molten iron using the cupola and induction furnace melting of the duplex, the intermediate complex is very useful for effective measures for desulphurization.
