摘要: 優(yōu)質(zhì)的圓管坯是生產(chǎn)高質(zhì)量無縫鋼管的前提。管坯的表面裂紋會(huì)對(duì)無縫鋼管的質(zhì)量產(chǎn)生極壞的影響。通過技術(shù)攻關(guān),解決了圓管坯的表面裂紋問題,為生產(chǎn)高質(zhì)量的無縫鋼管提供了優(yōu)質(zhì)的原料。Abstract: No quality round bloom, no quality seamless steel tube. Any surface cracking of the bloom will cause serious 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.
