半厘米厚的热轧钢板一圈圈地卷起来,成了直径近两米的钢卷。这个重达二三十吨的钢卷,在全自动化的生产线上像擀面皮一样,被轻轻松松地抻开、拉平、酸洗、压薄……经过了轧机的钢辊,钢板厚度生生轧薄到只有原来的五分之一。新钢板变得光洁如镜,闪烁着冷峻的光芒……这是5月2日记者在位于顺义区李桥镇的北京首钢冷轧薄板有限公司酸轧作业区看到的场景。北京首钢冷轧薄板有限公司是首钢所有涉钢企业在京关停后惟一留存的大型钢厂,产品定位于汽车、家电等高档板材。“这条生产线是首钢第一条冷轧生产线。2007年底投产,当初是白手起家,5年多的时间我们实现了跨越式发展。由当初设计产能150万吨发展到现在180万吨,产品被奔驰、宝马、现代等40多家汽车用户和海尔、美的、格力等30家家电用户采用。公司能取得这么快的发展,离不开全体职工的努力拼搏,酸轧作
Half a centimeter thick hot-rolled steel rolled up in a circle, became nearly two meters in diameter coil. The 20-30 tons of coil, in the fully automated production line like rolling the same skin, was gently opened, leveled, pickling, thinning ... ... After the rolling mill steel, sheet thickness of raw and rolling Thin to only one-fifth of the original. The new steel plate becomes smooth and glittering as a mirror. It is a scene that reporters saw on May 2 at the sour-rolling operation area of Beijing Shougang Cold Rolled Sheet Co., Ltd. in Liqiao Town, Shunyi District. Beijing Shougang Cold Rolled Sheet Co., Ltd. is the only large-scale steel mill in Shougang that all steel-related enterprises retain after the Beijing shut down. The products are located in high-grade steel such as automobiles and household appliances. ”This production line is the first cold-rolling production line of Shougang. Put into operation by the end of 2007, initially from scratch, more than 5 years we achieved leapfrog development. From the original design capacity of 1.5 million tons to the current 1.8 million tons, the product was Mercedes-Benz, BMW, Hyundai and more than 40 car users and Haier, the United States, Gree and other home appliances users 30. The company can achieve such a rapid development, inseparable from all the hard work of employees, Sour-rolling
