ALLOY FOR ELECTROSLAG WELDING-ON OF CAST IRON ROLLING ROLLS Russian patent published in 2003 - IPC

FIELD: ferrous metallurgy, namely chemical content of cast iron used as additive material for electroslag welding-on of cast iron rolling rolls of mills for hot rolling of wide strips. SUBSTANCE: alloy contains (mass.%): carbon, 2.4 - 2.6; silicon, 0.4 - 0.8; manganese,0.6 - 0.8; phosphorus, less than 0.08; sulfur, less than 0.05; chrome, 16 - 19; molybdenum, 0.8 - 1.5; nickel, 0.5 - 1.5; titanium, 0.03 - 0.06; copper, 0.8 - 1.0; ferrum - the balance. EFFECT: enhanced operational reliability of rolling roll, lowered energy consumption due to reduced time period of subsequent heat treatment.
