The 2021 Shenzhen International Additive Manufacturing, Powder Metallurgy and Advanced Ceramics Exhibition (Formnext+PMSouthChina) have been held in Shenzhen International Convention and Exhibition Center from September 9 to 11. Shenzhen, known as the "capital of scientific and technological innovation", has thus shown infinite vitality. Nearly 200 outstanding exhibitors from home and abroad bring world-leading technologies to this 15,000-square-meter event to provide a broad market opportunity for the manufacturing industry in South China. MoreSuperHard has sent two representatives to Shenzhen International Convention and Exhibition Center to participate in the exhibition and exchange learning.
There are a large number of carbides in the material of chilled cast iron rolls, which are composed of pearlite, cementite and ledeburite. The hardness of the roll itself can reach 65HRC or more, and there are often defects such as impurities and hard spots in the roll blank. When using tools for processing, the defects of the roll itself will cause severe impacts on the tools, and the increase in cutting temperature will increase the wear of the tools, so it is a kind of material that is more difficult to process.
