METHOD FOR MAKING THIN STRIP OF STAINLESS STEEL Russian patent published in 2003 - IPC

FIELD: manufacture of thin strip of stainless steel by direct solidifying of melt steel in the form of strip. SUBSTANCE: method is designed for making strip with thickness equal to 8 mm or less than it. Method comprises steps of making strip in casting plant having two moving cooled walls; hot rolling cast strip whose solidification is realized significantly when strip leaves moving walls; performing hot rolling in rolling mill whose rolling rolls have diameter 400 - 900 mm and achieving temperature of strip at outlet of rolling mill in range 800 -1100C. Degree of thinning strip at hot rolling process is in range 15 - 50%. Invention provides non-reversible closing of central pores and welding of mutually opposite walls of pores by rolling at predetermined conditions. EFFECT: irreversible closing of pores in middle of strip after solidification. 3 c, 2 tbl
