ELECTRIC ARC MELTING FURNACE AND METHOD OF OPERATION OF SUCH FURNACE

摘要

FIELD: metallurgy. ^ SUBSTANCE: lower part of electric arc melting furnace and/or resistance melting furnaces is surrounded with bowl-shaped jacket for cooling this part; cooling medium flows in intermediate space in direct contact with outer wall of furnace. Provision is made for one delivery hole and one drain hole. Transportation of cooling medium is effected due to convection and/or by means of pump or air blower. ^ EFFECT: increased service life of refractory lining due to optimal cooling of melting reservoir; low cost. ^ 9 cl, 2 dwg
