一种热镀锌自润滑钢板的生产方法
摘要：
本发明公开了一种热镀锌自润滑钢板的生产方法，属于钢铁制造技术领域。一种热镀锌自润滑钢板的生产方法，采用辊式涂布机将自润滑涂料涂覆在热镀锌板基材上，然后进行固化、冷却；所述辊式涂布机的涂覆工艺参数为：带钢的传送速度为60～120m/min；涂覆辊/带钢速比为130％～160％，粘液辊/带钢速比为70％～80％，涂覆辊与粘液辊间接触压力为40～80daN，涂覆辊与带钢之间的包角为15～25°，粘液辊粗糙度Ra为0.6～0.8μm，涂辊粗糙度Ra为1.3～1.6μm。其生产出的热镀锌自润滑钢板，膜层厚度均匀，具有优良的自润滑性、耐蚀性、耐热性、耐水性，且可以适用于各种自润滑涂料。
摘要（英）：

The invention discloses a production method of a hot galvanizing self-lubrication steel plate and belongs to the technical field of steel and iron manufacturing. According to the production method of the hot galvanizing self-lubrication steel plate, a roller type coating machine is adopted for coating a hot galvanizing plate base material with self-lubricating coating, and then curing and cooling are performed; and according to the coating process parameters of the roller type coating machine, the conveying speed of strip steel ranges from 60 m/min to 120 m/min, the coating roller/strip steel speed ratio ranges from 130% to 160%, the liquid adhering roller/strip steel speed ratio ranges from 70% to 80%, the contact pressure between a coating roller and a liquid adhering roller ranges from 40 daN to 80 daN, the wrap angle between the coating roller and the strip steel ranges from 15 degrees to 25 degrees, the roughness Ra of the liquid adhering roller ranges from 0.6 micron to 0.8 micron, and the roughness Ra of the coating roller ranges from 1.3 microns to 1.6 microns. The hot galvanizing self-lubrication steel plate produced through the production method is uniform in film layer thickness, has excellent self-lubricating performance, corrosion resistance, heat resistance and water resistance and is applicable to various kinds of self-lubricating coating.
