Effect of Heat Treatment Temperature on Microstructure and Properties of High Chromium Cast Iron (2)
The 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 […]

Analysis of heat treatment technology of Hi-Mn casting liners (2)
Big 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)
Abstract: 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 […]
The difference between the gas porosity and shrinkage cavity in casting process (2)
1) when non-ferro alloy is melted, charge, solvent, tool and ladle should be preheated and dried fully, rust and oil should be removed, and the amount of charge should be properly limited.
The difference between the gas porosity and shrinkage cavity in casting process (1)
Click here casting production, casting gas porosity, and casting shrinkage cavity are sometimes associated, sometimes in separate groups. When gas porosity and shrinkage cavity occur, we quickly determine whether the defect is a gas porosity or a shrinkage cavity is necessary to solve the problem. To quickly judge these two defects, you know their characteristics well at first. Today, we teach you […]
Brief Introduction of Casting
Casting is the process of melting the metal into a required liquid and pouring it into the mold. After cooling, solidifying and cleaning, a casting (part or blank) with a predetermined shape, size and properties can be obtained It is the basic technology of modern machinery manufacturing industry. The cost of casting blank is low, […]
