Title: Steelmaking process by using scrap containing cu and sn
Inventor: KAWACHI YUJI
IPC: C22C33/04
Filed: 1989-05-31
Abstract: PURPOSE:To obtain a leaded free cutting steel in which Cu and Sn are made innoxious while obviating the necessity of particular treatment by allowing Cu and Sn in scrap to be absorbed by Pb grains. CONSTITUTION:Granular Pb or Pb compound is added to a molten crude steel prepared by melting scrap containing Cu and Sn in a steel-works. Since Pb has a characteristic of forming low-melting alloys together with Cu and Sn, the Cu and Sn in the molten steel are absorbed by the Pb grains. As a result, respective concentrations of Cu and Sn in an iron matrix are reduced after the molten steel is solidified. On the other hand, the Pb grains in which Cu and Sn are absorbed have properties practically equal to those of Pb as simple substance. Accordingly, in the case of a leaded free cutting steel in which Pb is added in order to improve the machinability of steel, the leaded free cutting steel can be produced from a molten crude steel having, respectively, high Cu and Sn contents.
