Abstract
A process for the production of rustless iron or steel containing chromium and nickel is carried out as follows:-To a bath of 500 kilograms of molten iron or steel with the desired carbon content there is introduced 300 kilograms of chromite, 30 kilograms of nickel oxide, 150 kilograms of lime, 40 kilograms of fluorspar and 30 kilograms of bauxite, and to this mass, when molten to form an artificial slag, there is added a reduction mixture of metal oxides and reducing agents comprising 820 kilograms of chromite, 110 kilograms of nickel oxide, 316 kilograms of aluminium, and 82 kilograms of ferrosilicon. In the Specification as open to inspection under Sect. 91 the process may also be carried out by first bringing the reduction mixture to reaction temperature, then adding iron or steel and finally forming the artificial slag for refining. This subject-matter does not appear in the Specification as accepted.
