PROCESS OF CONTINUOUS MELTING WITH PROTECTED ARC OF A PARTICULATE MATERIAL CONTAINING METALS AND A PREPONDANCE OF SLAG FORMING CONSTITUENTS

摘要

P THE OVEN IS OPERATED IN A WAY THAT THE MAJOR PART OF THE ENERGY PROVIDED TO IT IS RELEASED IN THE ARC 5 AND A LOW PART IN THE MELTING BATH 8. THE ELECTRIC ENERGY IS ADJUSTED IN THE BATH DIRECTLY TO OBTAIN A REQUIRED ACTIVE SURFACE OF THE BATH WHICH IS CALCULATED BASED ON THE SPEED OF CHANGING THE VOLUME OF SLAGS AND INDIRECTLY FROM THE REPORT SILICA: MAGNESIA IN SLAGS. THE OPTIMAL INTERVAL OF THE ACTIVE BATH AREA IS OBTAINED FROM THE CONDITIONS OF CONTINUOUS AND SAFE OPERATION OF THE OVEN TO PROTECT WALLS 1 THEREOF FROM EROSION BY SLAGS AND TO AVOID EXCESSIVE MOVEMENT OF THE 'ELECTRODE 3. /P
