Abstract

128,836. Ryding, H. C., and Allen, A. W.. Nov. 21, 1918. Cast-iron processes.-Basic open-hearth steel is made from a charge of blown metal and slagforming material, e.g. lime and oxide of iron, the blown metal being added in two portions, one containing a low and the other a high percentage of carbon. The slag-forming material may be charged before the low-carbon metal, or after it and before the high-carbon metal, and these two methods of working may be employed alternately, so that the first method will effect a building- up of the furnace bed in consequence of the lime adhering to it, while the second method will result in the erosion of the bed so built up. Four parts by weight of low-carbon metal containing about 0.06 per cent of carbon and one part of high-carbon metal containing 2.5 to 3 per cent of carbon may be used.
