METHOD FOR INTRODUCING DEOXY-DESULPHURIZING SUBSTANCES INTO LIQUID METALS WITHOUT THE USE OF GASEOUS CARRIERS |
摘要 |
Substances such as deoxidizing and desulfurizing substances are introduced into liquid metal such as molten iron or steel, by forming layers of active material such as an alkali or alkaline earth metal or an oxide or halide thereof, is interlayered with inert material, in a metallic casing. The inert material may be iron or steel or a metallic oxide that is inert to the bath. The composite is immersed in the bath, thereby gradually to add the deoxidizing and/or desulfurizing materials to the bath. |
