INSTALLATION FOR ELECTROSLAG REMELTING AND SMELTING Russian patent published in 1997 - IPC

FIELD: metallurgy. SUBSTANCE: invention relates to installations for electroslag remelting of electrodes and noncompact blend into cooled crystallizer. Installation contains crystallizer mounted on frame, arrangement for drawing ingot, dispensers, and drawout carriage. Crystallizer is provided with graphite insertion installed in the upper slag zone coaxially and in spaced relation to crystallizer with gape size corresponding to slag scull size. Insertion is made with through openings positioned uniformly all along its height and having summary area 5-15% of insert surface area. EFFECT: reduced power consumption (by 30-40%) and prevented erosion wear of crystallizer in the flux bath zone. 2 dwg
