1、研究了酸洗温度、浓度、带钢运行速度等对酸洗速度的影响,测试了不同钢种的酸洗时篇一:影响酸洗带钢质量的因素分析影响酸洗带钢质量的因素分析在冷轧带钢生产中,影响其质量的因素很多,酸洗工艺是很重要的一个环节,带钢酸洗质量的好坏,直接影响其它工序的顺利进行。1热轧带钢表面的成分构成带钢表面的氧化铁皮是钢坯热轧时产生的氧化物,氧化物由Fe2O3、Fe3O4、FeO组成。由于各个钢厂的加工方法不一样,钢的表面温度、终轧温度以及周围介质的不同,所以带钢表面的氧化铁皮结构也不相同。酸洗的目的就是除去氧化铁皮。2原料轧制缺陷:因而轧制中边部出现微小裂
2、口(俗称芝麻口),严重时发生大面积裂口。宽度变化:带钢允许偏差为0~30mm。一般冷轧厂均有剪边功能,这样可以降低原料缺陷所带来的损失。为冷轧提高成材率和减少机组停机事故。3带钢外观(1)organizationsystemandworkingmode,theselectionofanumberofmunicipalstrengtheninggrouptobuildinnovationandstrengthentheorganizationofthebasiclevelorganizationsadvancedmodel.(seve
