一、气条和夹渣
1、 Air bar and slag inclusion
在铸轧上可能产生的原因:生产工艺没严格执行(精炼不到位)、炉外除气不到位(除气箱漏气)、铝水处理不到位、过滤作用不明显、空气湿气太重。
Possible reasons for casting and rolling: the production process is not strictly implemented (refining is not in place), the degassing outside the furnace is not in place (gas leakage in the degassing box), the aluminum water treatment is not in place, the filtering effect is not obvious, and the air moisture is too heavy.
整改措施:进行一次性投料、按操作工艺撒覆盖剂、加强精炼、解决除气箱漏气问题、铝水处理干净、增加过滤装置保证铝水经过过滤。
Rectification measures: conduct one-time feeding, sprinkle covering agent according to the operation process, strengthen refining, solve the problem of air leakage in the degassing box, clean the aluminum water, and add a filtering device to ensure that the aluminum water is filtered.
二、长条状小裂口
2、 Elongated small fissure
铸轧上可能产生的原因:咀皮损坏或损伤
Possible causes on roll casting: nozzle skin damage or damage
整改措施:咀皮存在以上问题立刻断板,保证生产时咀皮完好。
Rectification measures: if the nozzle skin has the above problems, the plate shall be broken immediately to ensure that the nozzle skin is intact during production.
三、黑条
3、 Black bar
铸轧上可能存在的问题:工艺没有执行到位,铝水处理不好。
Possible problems in casting and rolling: the process is not implemented in place and the aluminum water treatment is not good.
整改措施:制定生产工艺,加强铝水处理。
Rectification measures: formulate production process and strengthen aluminum water treatment.
四、擦划伤
4、 Scratch
铸轧可能产生的原因:剪板机下台面磨擦铝板表面造成。
Possible causes of casting and rolling: the lower table surface of the shear rubs against the surface of the aluminum plate.
整改措施:对剪板机下台面进行整改。
Rectification measures: rectify the lower table of the plate shear.
