为满足市场需要 ,攀钢于 1 999年开始研究开发“以热代冷”的热轧酸洗板 ,以取代部分冷轧板。这种热轧酸洗板对质量的要求为 :①必须具有接近冷轧板的表面质量 ;②厚度公差范围要求比较严 ,一般要求≤ 0 2 5ｍｍ ;③高于标准要求的使用性能 ,例如 ,冲压用热轧酸洗板的δ50 要 To meet the needs of the market, Panzhihua Iron and Steel in 1999 began to study the development of “hot cooling” hot-pickling to replace some of the cold-rolled plate. This hot-rolled pickling the quality requirements are: ① must have the surface quality close to the cold-rolled plate; ② Thickness tolerance requirements more stringent, the general requirements ≤ 0 2 5mm; ③ higher than the standard performance requirements, for example, Stamping hot-rolled pickling plate δ50 to
