Abstract

Abstract

A new-type weathering steel 06CuPNi1Cr2 was developed by high-efficiently utilizing nickel and chromium in low nickel-chromium laterite ores.The influences of bath temperature and the partial pressure of carbon monoxide on decarburization and keeping chromium were studied and discussed to solve the problem of chromium oxidation in steelmaking.06CuPNi1Cr2 smelting experiments show that the effects of decarburization and keeping chromium are remarkable when the oxygen top-blowing is 3.0 to 3.3m³·min^-1·t^-1,the mass fraction of final carbon is 0.02% to 0.05% and the end-point smelting temperature is 1680 to 1700℃.
