PRODUCTION OF AGENT FOR DESULFURIZING CRUDE IRON AND STEEL MELTS ABSTRACT OF THE DISCLOSURE The invention relates to the production of an agent for desulfuriz- ing crude iron and steel melts, the desulfurizing agent being based on cal- cium carbide containing calcium carbide To this end, a calcium carbide/cal- cium oxcide/starting melt mixture with a CaO-content within the range 20 to 80 weight% is produced from lime and coke and allowed to solidify to a block. While the solidified block still has an average temperature of more than 400 C, it is crushed to particulate material with a size of less than 150 mm. Next, the hot crushed material of at least 400° C is admixed with a quantity of calcium oxide necessary to have in the resulting mixture an overall con tent of CaO corresponding to that desired for the final product. The whole is thoroughly mixed and crushed with exclusion of moisture at temperatures higher than 100° C to particulate material with a size of less than 10 milli- meter.
