摘要

The author has conducted physicochemical studies of the cast iron smelting processes in cupola furnaces. A design of gas cupola furnaces and a technology of smelting high quality cast iron in gas cupolas have been proposed. The technical properties and gas content of cast irons produced in coke and gas cupola furnaces have been investigated. It has been demonstrated that the properties of the cast iron from gas cupola furnaces were higher, and its structure and composition were more fitting for a compressor sheet, which has been achieved by decreasing the detrimental sulfur content and by appropriate content of nitrogen and oxygen in the microstructure of solidified cast iron.
