一、序言酸洗作业线要在其入侧将钢卷状的带钢相互焊接起来,进行连续酸洗处理。过去,这种焊接主要由闪光对焊焊接机来完成。其优点是焊接处理时间短并可获得较好的焊接接头,许多作业线均采用这种焊接机。然而,闪光对焊焊接机焊接时线能量大,所以被焊材料的范围有限,特别是对于高牌号硅钢或铁素体不锈钢则不能确保其焊缝强度,不仅在冷轧时会产生断带现象,甚至在酸洗时也会断带。 First, the pretreatment pickling line to be in its entry side of the steel strip welded together, for continuous pickling. In the past, this welding was mainly done by a flash butt welding machine. The advantage is that the welding process time is short and can obtain a better welded joints, many operating lines are using this welding machine. However, the flash butt welding machine has a large amount of line energy during welding, so the range of materials to be welded is limited. Especially for high grade silicon steel or ferritic stainless steel, the weld strength can not be ensured, and not only the breakage phenomenon occurs during cold rolling , Even when pickling will be broken.
