Resin coated sand casting has a long history in the field of casting, and the output of casting is quite large, but there are many problems when using resin coated sand casting to produce precision steel castings, such as sand burn, cold shut, and air hole. How to solve these problems remains to be explored. […]
The common defects and main causes in the process of using coated sand and the main causes of the name of the defect (1) the loose surface of the mold (core) core pressure is too high or too low; the molded exhaust is not smooth; the mold runs because of the big clearance of the […]
Throughout the production of wear-resistant ball casting from forging, sand casting, iron mold casting to the current sand-coated iron casting, each is a qualitative leap. With the development of new technology, there is still a small proportion of wear-resistant steel balls in the mining market because of their advantages in impact toughness, but the market […]
SAND-COATING TECHNOLOGY IN IRON MOULD is a new technology for producing wear-resistant grinding balls. It has the advantages of both iron mould and sand mould. It has the characteristics of chilled iron mould, small stress and good toughness in Sand Mould Casting. This is a very big breakthrough in the production of wear-resistant grinding balls. In […]
Generally speaking, the end customers of wear-resistant materials companies mainly include mining, cement, construction and power plants. The performance of the wear-resistant steel ball is related to the cost and benefit of the end-user enterprise. At present, with the technical improvement of wear-resistant casting companies, the replacement of low-efficiency steel balls with high-performance and high-grinding […]
The AUTOMATIC SAND-COATED METAL MOULD PRODUCTION LINE adopts the advanced sand-coated metal mold producing process, which can significantly improve the mechanical properties of castings, improve the appearance quality of castings, reduce the machining allowance of castings & the labor intensity & the number of workers, minimize the production of safety hazards.
ABSTRACT: The heat treatment process of high chromium grinding ball produced by sand coated iron mould casting process was researched. Shrinkage and porosity defects have not been discovered after cutting along the diameter of grinding ball. The grinding ball in cast state has poor mechanical properties. Mechanical properties of grinding ball significantly increase after heat treatment After heat […]
