Research on Cost-effective New Alloy Cast Iron

Abstract

Cast iron is the basic material of the manufacturing industry. It has excellent casting processability and good shock absorption and wear resistance, so it is widely used. With the awareness of energy conservation and environmental protection, the defects of low energy and high consumption of traditional materials are gradually revealed. They are gradually being replaced by new alloy cast iron. This paper introduces the latest developments in new alloy cast iron production technology in recent years in detail, involving iron purification, furnace selection, melt ratio, chemical composition control, inoculant type and application, and stress relief annealing. And this paper analyzes the strengthening mechanism of cast iron, puts forward the problems and solutions in the production process, and expounds the development trend of cast iron production technology and the prospect of China's cast iron industry.
