板卷在热轧过程中其表面易形成一层又脆又硬的氧化物，在进行冷轧加工之前， 必须去除带卷表面的氧化物，这一工序通常由酸洗机组来完成。酸洗生产线是我 公司较为成熟的技术，目前我们可为客户提供；推拉式酸洗生产线（即半连续式 酸洗线）和连续式酸洗生产线。

A layer of brittle and hard ferric oxide will form on the surface of the steel strip during the hot rolling,and the ferric oxide layer will affect the surface quality of the strip during cold rolling.Pickling process is applied for removing the ferric oxide.We are professional in this technology,and we can provide the following kinds of pickling lines,Push-pull Pickling Line (Semi-continuous Pickling Line)and Continuous Pickling Line.

推拉式酸洗生产线 Push-pull Pickling Line

推拉式酸洗生产线是一种半连续式生产线，具有设备简单，适用带钢品种多、生 产消耗低、设备运行故障少等特点。该机组适于年产量为10-60万吨的生产。

Push-pull Pickling is a semi-continuous production line. It is characteristic with lower consumption,easier operation and fewer malfunctions,moreover it can pickle many kinds of incoming material. The line can produce 100,000-600,000 tons strip annually.
