Abstract
In a process for the production of steel in the basic open hearth furnace, a charge containing 1,6 to 2,4 per cent of manganese is smelted to produce a steel containing 0,8-1,2 per cent of manganese and then the subsequent oxidation is carried out more rapidly than usual, e.g. for a period not exceeding one-half the normal period so as to transfer the bulk of the manganese to the slag. Basic compounds, such as lime, are then added to the bath and the temperature of the melt is increased to at least 1600 DEG C. so as to transfer the manganese in the slag continuously into the bath. This temperature is maintained for a comparatively long time e.g. 1 1/2 hours, periodical analyses of the content of the bath being made to ensure that the manganese content of the melt is increasing and that therefore the temperature of the bath is being maintained. The heating is continued until the desired carbon content of the steel is reached, and the metal is then tapped. Additions of alloy constituents such as chromium, molybdenum, vanadium, titanium or tungsten may be made to the bath either in the furnace, during the tapping off or in the pan. Alloy steels containing 0,4 per cent of chromium or 0,45 of molybdenum are referred to.
