The all-steel anti-static movable floor is made of high-quality cold-rolled steel sheets, which are punched, spot-welded, coated by electrostatic spray after phosphating treatment.

全钢抗静电活动地板采用优质合金冷轧钢板，经拉伸后点焊成形。

The methods to improve the intensity of cold-rolled sheets is to add some useful alloying elements during steel-making and improve the cooling rate annealing treatment.

提高冷轧薄板机械强度的方法主要是在炼钢时添加有益的合金元素及在热处理时提高退火后的冷却速率。

To meet uninterruptedly increasing in the demand for the cold rolled steel sheets and to meet the technological demand of continuous annealing, the production of ultra-low carbon steel is increasing.

为了满足市场对冷轧薄板钢需求量的不断增加和连续退火工艺要求，超低碳钢生产也在不断增加。
