摘要

兴澄特钢Φ120～300 mm碳素和合金结构钢由370 mm×490 mm连铸坯轧制。在中间坯火焰清理工艺的金属损耗较砂轮剥皮工艺的金属损耗高1.5%～2.0%

但表面质量高

废品率减少0.5%～1.0%。火焰清理的生产效率高

清理质量好

适合表面质量要求高的产品。

Abstract

120～300 mm heavy section bars of carbon and alloy constructional steel are rolled by 370 mm × 490 mm cast bloom at Xingcheng Special Steel.As comparing with grinding wheel peeling process

the metal loss by in-line flame cleaning process is higher by 1.5%~2.0%

but the surface quality of products is higher than that by grinding process

the rejection rate decreases by 0.5%~1.0%.The production rate of cleaning by flame cleaning process is higher and cleaning quality is higher than that by grinding process

the flame cleaning process is available for high quality surface products.
