The mill housing is also known as rack, frame body, is an important part of hot rolling, cold rolling,etc rolling mill, due to the poor working environment of the mill,the roller will make greater impact to the rack through the bearing seat during the work,so that the inside of the window surface and the bottom of the rack are varying degree of corrosion wear which leads to the gap between the mill rack and the roll bearing block to exceed the limit value.
1. According to the preliminary process of simulated solidification,analysis,demonstration,complete the optimization of the casting process to ensure the casting milling house without shrinkage,compactness,comprehensive mechanical properties.
2. Aopts the modification treatment and ladle bottom blowing argon technology to strictly control the quality of molten steel to reduce the gas and harmful elements in the molten steel,and improve the purity of molten steel to ensure that quality of rolling mill house.
