How does precision casting work?

- Apr 16, 2019-

In steel mills, depending on the quality requirements, the following processes can be adopted: - Desulfurization of low-phosphorus pig iron by the Rhine Steel Plant Mixing Method, - Alkaline Top Blowing to P Top with "Low Phosphorus" Method for Pig Iron and Passing The selected scrap is refined, - in steel ladle with excellent lining and preheating, - a gas mixture is added to homogenize the molten steel. First, to minimize the sulfur content, the steel is treated with calcium according to TN technology. , - Vacuum treatment by RH method, if necessary, in conjunction with vacuum carbon deoxidation or vacuum decarburization, after which the carbon content can be minimized, and finally bet, and gas maintenance should be used if necessary. The use of excellent linings in ladle, such as high-aluminum p-oxidized or self-cloud-like lining, is to prevent the adverse effects of the exhausted oxygen on the purity of the ingot for precision casting.


Mechanical root parts mainly refer to: bearings, gears, molds, hydraulic parts, pneumatic components, seals, fasteners, etc., which are indispensable components of the manufacturing industry, directly determining the functions of serious equipment and mainframe products. Level, quality and reliability. The precision casting processing plant has gradually developed and achieved results.
