METHOD OF PRODUCTION OF 1,8-2,0 mm THICK SEMI-FINISHED HOT-ROLLED STEEL STRIP STOCK FOR ENAMEL COATING Russian patent published in 2010 - IPC C21D8/04 C21D9/48 C22C38/08

Abstract RU 2392335 C1

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 560°C or higher is placed in continuous furnace and heated at 1240-1280°C for 210-240 minutes, and coiling of semi-finished hot-rolled stock is performed at 730-760°C.

EFFECT: improved consumer characteristics.
