一、引言在研究冷轧钢板铁皮缺陷的过程中,曾发现铁皮缺陷在个别炉罐号上大量出现,缺陷的部位大部份在距离钢板两边250毫米范围内,缺陷的形状呈大点状。特别引人注意的现象是:当二轧热轧沸腾钢板时,除鳞良好;而轧制镇静钢板时炉生铁皮很不易除净。但冷轧板上的反映则恰恰相反,即沸腾钢铁皮缺陷多而镇静钢

I. INTRODUCTION In the process of studying the defects of cold-rolled steel sheets, it has been found that a large number of tin defects appear on individual furnace numbers. Most of the defects are located within 250 mm from both sides of the steel sheet, and the shape of the defects is larger. Particularly noteworthy phenomenon is: When the second rolling hot-rolled steel plate, the descaling good; and when the rolling of steel plate is not easy to clean the furnace skin. But the cold-rolled plate on the contrary is the opposite, that is, boiling steel and more defects and more calm steel
