METHOD OF MAKING BIMETALLIC ROLLING ROLLS Russian patent published in 1997 - IPC

FIELD: electroslag process, namely production of rolling rolls. SUBSTANCE: when band and solenoid- electrode are placed into casting mold coaxially with seed-electrode in such a way that solenoid-electrode is spaced by distance equal to 5-100 mm from inner surface of band after producing and feeding liquid slag with the aid of intermediate apparatus, predetermined interelectrode gap is stabilized due to changing mass velocity of melt metal pouring from said intermediate apparatus with use of stopper in dependance upon intensity of electric current passing through melted electrode and slag bath. EFFECT: enhanced quality of rolls made by such method. 1 dwg
