上海汽车结构钢性能特性用途大全详细介绍
热轧酸洗产品以其表面质量、节省工序能耗等独特优势,越来越多地被应
用在汽车制造行业,成为汽车底盘、车轮、座椅、安全构件等的主要材料。宝钢
以满足用户需求为导向,紧密跟踪汽车行业发展动态,凭借长期积累的生产技
术,进行热轧酸洗汽车板产品的探索和实践,生产出具有良好品质的系列化产
品,并实现了批量稳定供货,满足汽车安全性和经济性的要求,在通用、大众、
东风日产等品牌车型上批量使用,受到汽车用户的青睐。
With unique advantages in surface quality and economic producing processes, hotrolled
pickled products have been widely used in auto manufacturing as one of the main
materials for chassis, wheel, seat and safety components. Baosteel has been closely following
the developments in the automotive industry to meet customers’ demands. With long-term
accumulated technology in production, Baosteel has been exploring and practicing on the
producing of hot-rolled pickled automotive sheets products and has developed a series of
products with excellent quality. Baosteel has the capability for stable batch supply and
meets the safety and economy requirements of automobiles. It’s products have been mass
used by GM, Volkswagen, Dongfeng-Nissan in their various types of vehicles and have
been widely favored by users.
宝钢目前有2条可生产热轧酸洗板的机组,宝钢直属厂部连续酸洗机组和不锈钢事
业部碳钢酸洗线。直属厂部连续酸洗机组于2001年投产,设计年产量75万吨。不锈钢事业
部碳钢酸洗线于2008年初投产,设计年产量140万吨,其中酸洗商品卷63.4万吨。宝钢酸洗
机组引进德国SMS-DEMAG、SIEMES、MIEBACH、DUMA等厂商的关键技术和设备。主要工
序有激光焊接、拉伸矫直、紊流酸洗、在线平整、切边、涂油等。另外,为了满足汽车、家电
等行业发展需要,宝钢计划在2011年投产一条酸洗机组,设计年产量100万吨。
Currently, Baosteel has two product lines of hot-rolled pickled sheets. One is the Baosteel directly
owned continuous pickling line and the other is the Stainless Steel Business Unit’s carbon steel pickling
line. The directly owned continuous pickling line started production in year 2001 with design capacity
of 750,000 tons per year. The carbon steel pickling line of Stainless Steel Business Unit started in
2008, with an annual output of 1,400,000 tons which includes 634,000 tons of commercial pickled
rolls. Baosteel’s pickling line has introduced key techniques and equipments from German companies
such as SMS-DEMAG, SIEMES, MIEBACH, DUMA. Main processes include laser welding, stretch
rolling, turbulence pickling, on-line leveling, trimming, oiling, etc. In addition, to meet the demands
of automobile and household appliances industries, Baosteel has planned to start another pickling line
in 2011 with an annual capacity of 1 million tons.

产品特点
(1) 用盐酸将热轧钢板上的氧化铁皮清除后得到漂亮、光滑的表面,便于焊接、涂油和上漆,经过平整,使钢
板表面更接近冷轧板表面
(2) 切除不规则的头尾、按产品宽度切除热轧带钢的边部,以利于后序加工
(3) 检查并清除钢板表面不利于后道工序的缺陷
(4) 对带钢表面涂油,以防钢卷在存放期间发生锈蚀
(5) 尺寸精度高,经拉矫、平整后可改善带钢板形
(1) Smooth surface is obtained by using hydrochloric acid to remove the scale on the hot-rolled strips, thus makes it easier for
welding, oiling and painting. The surface is more similar to the cold-rolled steel surface after temper rolling.
(2) In order to facilitate the processes followed, irregular heads and tails are removed and the edges of the hot rollde strips are
trimmed according to the width of the products.
(3) Surface defects on the sheets which are not conducive to the processes followed are examined and eliminated.
(4) The strip surface is oiled to prevent it from rusting during storage.
