COMPOSITION TOOL FOR MOLTEN STEEL TREATMENT AND METHOD OF ITS PRODUCTION Russian patent published in 1995 - IPC

Abstract RU 2048537 C1

FIELD: metallurgy, for addition into molten bath alloying, modifying and slag-forming components. SUBSTANCE: tool presents metal shell, assembled as overlapping, and composed of separate cavities, filled with filler. Cavities are separated from each other by pinches, that are made of several layers in parallel to overlapping. To shape pinch shell surface is first bent inside by air of shaping tools till its walls inner surfaces touch each other in center. Then using pair of flat tools in plane, that is in parallel to overlapping, shell cavities are flattened till they achieve flat state. EFFECT: tool helps to facilitate alloyed steel production. 2 cl, 5 dwg
