前言在半成品初轧坯、连轧坯及板坯表面上难免有各种类型的缺陷,如:结疤、裂纹、气泡等。为不使这些缺陷带到成品钢材的表面上,对半成品坯料必须进行表面清理。目前,鞍钢主要采用火焰法和风铲法两种。对碳钢多采用火焰法,合金钢多采用风铲法。其中火焰法是发展的方向。为扩大火焰法清理的钢种范围,现就火焰法主要技术问题之一的火焰清理温度制度做如下探讨。
Preface It is inevitable that there are various types of defects, such as scarring, cracks and bubbles, on the surface of preform, preform and slab. In order not to bring these defects to the surface of the finished steel, the surface of the semi-finished product must be cleaned. At present, Anshan Iron and Steel mainly used two methods of flame and shovel. More use of flame carbon steel, alloy steel and more use of wind shovel method. Flame method which is the development direction. In order to expand the scope of the flame-cleaning steel, flame flame temperature control system is now one of the major technical issues to do the following discussion.
