近三十年来,用户对钢铁产品的表面质量提出了更高的要求。为此,冶金厂均求助于火焰清理机以清除钢坯含有缺陷的表面层,提高产品质量。这种清理方法有两种工艺系统,一种是热火焰清理法。钢坯加热轧制后,当钢坯处于热态(1050～1100℃)时,即在轧制线上用火焰清理机清除钢坯表面的缺陷。一道次能清除钢坯表面0.8～4.2毫米 In the past three decades, users have put forward higher requirements on the surface quality of steel products. To this end, metallurgical plants are resorted to the flame cleaning machine to remove the surface defects of the billet, improve product quality. This method of cleaning has two kinds of process systems, one is hot flame cleaning method. After billet heating and rolling, when the billet is in a hot state (1050 ~ 1100 ℃), that is, in the rolling line with a flame cleaning machine to remove defects on the billet surface. A time to clear the billet surface 0.8 ~ 4.2 mm
