Evolution of the production process of casting microspheres with diameters below 30mm

1) In the early 1990s, China cast microspheres below 30mm, which were developed and produced in Ningguo, Anhui Province. At that time, the pulverized coal molding process was used, which was purely manual operation, and the process was relatively simple and the production efficiency was low.

2) At the beginning of this century, Ningguo wear-resistant manufacturers have introduced vertical parting and horizontal parting processes of tidal mold sand for casting microsphere production. The above process mechanized operation, continuous work, high production efficiency.

3) In recent years, some wear-resistant manufacturers in Ningguo have taken the lead in adopting the coated sand shell process for the production of microspheres. Some manufacturers use vertical parting, and some use horizontal parting. The process has the advantages of high strength of sand mold, high roundness of steel ball and high production efficiency, and is favored by the majority of users.
