Zusammenfassung:The invention discloses a controlling method for preventing a thin scale checkered plate from generation of red rust. The controlling method comprises the following steps: a heated steel plate is subjected to rough rolling and a rough rolled steel plate is obtained; the rough rolled steel plate is subjected to finish rolling and a finish rolled steel plate is obtained; and the finished rolled steel plate is subjected to laminar cooling until the crimp temperature of the finish rolled steel plate is lower than or equal to a preset temperature, and the preset temperature is 580 DEG C. Accordingto the provided controlling method, the finish rolled steel plate is subjected to laminar cooling so the crimp temperature of the finish rolled steel plate is controlled below 580 DEG C; by lowering the crimp temperature of the finish rolled steel plate, the red rust can be effectively prevented from appearing on the checkered plate; and the product quality is improved and users' needs are satisfied. 本发明公开了一种防止薄规格花纹板产生红锈的
