针对带钢在加工使用过程中出现的弯裂现象，对于两种不同厚度规格出现弯曲开裂现象的带钢进行了金相分析、气体含量分析和SEM分析，认为带钢中夹杂物含量，钢中氧含量，以及皮下气泡经轧制后暴露是引起带钢弯裂的主要原因。
Aiming at the bend crack phenomenon in the course of processing and serving, the bend crack of strip steel with two different thick was investigated by means of metallographic and SME examination,as well as gas content analysis. It is suggested that the inclusions, the content of oxygen and the subcutaneous bubble emerged after rolling are the main reasons which result in bend crack of strip steel.
