Title:
高ケイ素の帯状鋼の破損を防ぐための冷間圧延方法
Document Type and Number:
Japanese Patent JP5818812
Kind Code:
B2
Abstract:
A cold-rolling method for preventing fracture of high-silicon strip steel, characterized in that the high-silicon strip steel has Si content‰¥2.3wt%, and at the beginning of cold-rolling, temperature of inlet strip steel is above 45°C; during the cold-rolling process, emulsion liquid is sputtered to the strip steel, flow rate of the emulsion liquid is 3500L/mm at the inlet in rolling direction, flow rate of the emulsion liquid is 1500~4000L/min at outlet in rolling direction, and temperature of the strip steel is ensured being above 45°C under the precondition to guarantee technological lubrication. The cold-rolling method of the invention might prevent fracture of head portion and tail portion of the strip steel, raise rate of finished products and production efficiency.
