Effect of Heat Treatment Temperature on Microstructure and Properties of High Chromium Cast Iron (2)
/in Castings /by Sara WuThe hardness of the tested sample after heat treatment at medium temperature (740 ~ 820 °c) is shown in Table 3. The corresponding metallograph is shown in Fig. 2. It can be seen that the hardness of hypoeutectic high chromium cast iron after heat treatment at medium temperature has significant change compared with the as-cast […]

/in Castings /by Sara WuAnalysis of heat treatment technology of Hi-Mn casting liners (2)
/in Castings /by Sara WuBig and medium size of the liners It is essential to preheat and even temperature operation of the lining plate, directly related to the toughness of the lining plate. The quenching process includes expanding preheating and homogenizing. In this process, the influence of thermal stress and microstructure stress should be considered. This two types of […]
Analysis of heat treatment technology of Hi-Mn casting liners (1)
/in Castings /by Sara WuAbstract: The lining plate is an essential part of the composition of the machinery and equipment on the mine. In the production of the ore, it needs to be in direct contact with the ore material. After being subjected to a lot of pressure and wear, it can also maintain its original quality and performance […]
Ten tricks for improving grinding efficiency of ball mill-2
/in Mines /by Sara WuThe grinding concentration affects the pulp’s specific gravity, the adhesion of ore particles around the ball, and the fluidity of pulp. Low grinding concentration, fast slurry flow, low adhesion of material around the ball, so that the impact of the ball on the material and weak grinding role, the size of ore discharge unqualified, grinding […]
