METHOD OF PRODUCTION OF 1,8-2,0 mm THICK SEMI-FINISHED HOT-ROLLED STEEL STRIP STOCK FOR ENAMEL COATING

摘要

FIELD: metallurgy. ^ SUBSTANCE: obtainment of enamel coating strip free of fish-scale flaw involves continuous pouring of steel containing, wt %: carbon 0.02-0.05, aluminium 0.05 or less, nickel 0.05-0.08, boron 0.001-0.003; slab heating, hot rolling in a mill, coiling of semi-finished hot-rolled stock of 1.8-2.0 mm thickness into a roll. Slab of the temperature of 560C or higher is placed in continuous furnace and heated at 1240-1280C for 210-240 minutes, and coiling of semi-finished hot-rolled stock is performed at 730-760C. ^ EFFECT: improved consumer characteristics. ^ 1 ex, 1 tbl
