Method for removing oxides on surface of hot-rolled strip steel
The invention relates to the field of material surface treatment, and particularly relates to a method for removing oxides on the surface of hot rolled strip steel. The method aims to overcome the problem that a large amount of acid mist and waste acid are generated during pickling of the oxides on the surface of a hot-rolled steel plate and seriously pollute the environment at the present. The method comprises the following steps that calcium carbonate, silicon carbide, graphite powder and an adhesive are stirred and mixed uniformly according to a certain proportion and then are subjected tohot pressing at a certain temperature to prepare a friction block for treating the oxides on the surface of the hot-rolled strip steel, the desorbed oxides are subjected to vacuum adsorption, the oxides can be well removed, dust pollution to the environment is avoided, and when the strip steel treated by the friction material reaches a certain cleanliness, the surface treatment of the steel is finished. According to the method for removing the oxides on the surface of the hot-rolled strip steel, the oxides on the outer surface of the strip steel can be rapidly treated, acid pickling is not needed, remarkable economic and environmental benefits can be generated, and wide application prospects are achieved.
本发明专利涉及材料表面处理领域，具体涉及的是一种热轧带钢表面氧化物的去除方法。本发明专利目的在于克服目前热轧钢板表面氧化物酸洗时产生大量酸雾、废酸，严重污染环境的问题。本发明实施过程如下：将一定比例的碳酸钙、碳化硅、石墨粉和粘合剂，搅拌混合均匀后，在一定温度下热压，制成摩擦块，用于处理热轧带钢表面氧化物，脱附下来的氧化物采用真空吸附，氧化物可以得到很好的去除，避免了粉尘污染环境，摩擦材料处理带钢达到一定的洁净度时，钢材表面处理完成。本发明可以快速处理带钢外表面的氧化物，不需要酸洗，能够产生显著的经济和环境效益，具有广泛的应用前景。
