TECHNOLOGY TO PROCESS SLAG-FORMING MATERIALS Russian patent published in 2003 - IPC

FIELD: processing of hard materials and/or their compositions. SUBSTANCE: invention cab find use in public utilities, power engineering, metallurgy, mining industry and so forth. Technology includes loading of slag-forming material into furnace under downward flow of melt with mass relation of slag melt to fed slag-forming material more than 100:1, blow-through of melt with oxygen-carrying gas with formation of foam layer of slag melt, creation of conditions of emergence of gas-lifting flow of slag melt and slag-forming material and discharge of waste gases and portion of slag melt. Speed of movement of slag melt and slag-forming material over horizontal section of trajectory of gas-lifting flow is found periodically or constantly and speed of movement of slag melt and of slag-forming material over horizontal section of trajectory of 3.0 m/s or over is set by way of change of modes of blow-through of slag melt. EFFECT: raised versatility of technology processing slag-forming materials. 16 cl
