发明名称 PRODUCTION METHOD OF AUSTENITIC STAINLESS STEEL PLATE
摘要 PROBLEM TO BE SOLVED: To provide a production method for an austenitic stainless steel plate capable of manufacturing a cold rolled steel plate excellent in gloss and polishability of the surface without excessively dissolving a hot rolled steel plate. SOLUTION: When the hot rolled steel plate made of austenitic stainless, steel processed with acid pickling after intermediate anealing in an anealing-acid pickling line is cold rolled at a rolling ratio X (%), the hot rolled steel plate is intermediately anealed, processed with acid pickling, and cold rolled, in the condition that a rolling rate constant RN (%) stipulated in the following formura (1), RN=A.(a.exp(-Q/R.T)/V)<n> +B.(b.S.L/V)<m> +C...(1), wherein, A, B, C, n, m: constant, a: constant for adjusting dimension (=1 min/m), b: constant for adjusting dimension (=1 min/μm), Q: activating energy (J/mol), T: anealing temperature (K) in intermediate anealing, R: gas constant (=8.31 mol K/J), V: carrying speed of a hot rolled steel plate in the anealing-acid pickling line (m/min), S: dissolving speed by acid during intermediate acid pickling (μm/min), L: effective total length of acid pickling tank (m).
