ROLLING MILL HOUSING

Rolling mill housing also known as rack and frame, is an important part of hot rolling, cold rolling, continuous rolling and other rolling mills. Due to the harsh working environment of the rolling mill, in the process of work, the roll through the bearing pedestal has a greater impact on the rolling mill housing, so the quality requirements are strict, and there are no casting defects such as inclusions, shrinkage cavities, porosity, cracks, etc. The rolling mill housing requires not only accurate dimensions, but also high mechanical properties of steel castings.

Our rolling mill housing adopts standard wooden model, and the surface of the core is brushed with special paint layer to prevent cracking, so as to ensure that the surface of the casting is smooth and smooth.

During melting, samples are taken three times before, as cast, and after the furnace, and analyzed using a German imported spectrometer to ensure that the composition is qualified;

we have more than ten years of technical experience, especially in order to ensure that the casting process design of products can be accurate, Huazhu CAE casting process analysis software is used to simulate the filling and solidification process of rolling mill housing, and then analyze the thermal stress and strain of products, optimize and improve the casting technology.
