摘要
优质的圆管坯是生产高质量无缝钢管的前提。管坯的表面裂纹会对无缝钢管的质量产生极坏的影响。通过技术攻关,解决了圆管坯的表面裂纹问题,为生产高质量的无缝钢管提供了优质的原料。
No quality round bloom, no quality seamless steel tube. Any surface cracking of the bloom will cause ser- ious quality problem. Thanks to technical efforts, surface cracking of the round bloom is eliminated, which provides a good basis for producing quality seamless steel tubes in terms of material preparation.
