Description

Technical field [0001] The invention belongs to the technical field of pig iron castings, and specifically relates to an additive for improving the wear resistance of pig iron castings. Background technique [0002] Pig iron is an iron-carbon alloy with a carbon content of more than 2%. Industrial pig iron generally has a carbon content of 2.11%-4.3%, and contains C, Si, Mn, S, P and other elements. It is smelted from iron ore in a blast furnace product. According to the different forms of carbon in pig iron, it can be divided into steel-making pig iron, cast pig iron and ductile iron. [0003] With the advancement of modern science and technology, especially the rapid development of aerospace and aviation, the use of large-scale atomic energy, and the emergence of new industries such as ocean development, higher and higher requirements are placed on structural materials. The performance of traditional pig iron materials cannot meet the market. Demand. Summary of the invention ...
