BILAMINAR HIGH-STRENGTH STEEL SHEET TOLERANT TO DYNAMIC EFFECTS AND METHOD OF ITS PRODUCTION

摘要

FIELD: process engineering.SUBSTANCE: invention relates to production of materials for armoured structures to be used at dynamic loads. Proposed method of sheet steel production comprises explosion welding sheet steel face and rear sides. Then, bilaminar sheet is tempered at 600-650°C. Then, sheets are heated in furnace to 1050-1150°C and rolled at 1150-800°C to total reduction of 30-40%. Now, performed are quenching in oil or water at 900-950°C and tempered at 170-200°C with cooling in air.EFFECT: higher strength.3 cl, 1 tbl, 1 ex
