Abstract

PURPOSE: To prevent the titled material from generating surface-flows without controlling complicated conditions such as hot rolling ones in a hot rolling of the material, by restricting the ion concentration of cooling water for rolling rolls within a range of conditions obtainable from the relative equations.
CONSTITUTION: The ion concentrations of Cl- ion and CO3 2- ion of cooling water for descaling rolls and rolling rolls are restricted within the ranges of conditions of the equationsI, II, and are made ≤200ppm Cl- ion concentration and ≤500ppm M value. Then stainless steel material is hot rolled by merely controlling the quality of water used for the hot rolling without controlling complicated conditions such as a slab heating temp., heating time, atmosphere of a heating furnace, and rolling pass schedule.
