连轧无缝钢管生产时产生的质量缺陷的控制

Control of Quality Defects in Continuous Rolling Seamless Steel Pipe Production

摘要

连轧无缝钢管生产中，质量缺陷是影响产品性能和使用寿命的主要因素。论文通过对生产过程中各关键环节的分析，探讨了控制质量缺陷的技术手段。首先，原材料的选择与冶金质量对钢管的内外部缺陷有直接影响，需严格控制钢坯的冶炼和预处理工艺。其次，加热过程中温度的不均匀和氧化皮生成会导致钢管表面和内部缺陷，因此需精确控制炉温和气氛。轧制环节中，合理设置轧制参数、维护设备精度至关重要。最后，冷却与热处理的优化能有效减少残余应力和组织不均匀，提升钢管质量。

Abstract

In the production of continuous rolling seamless steel pipe, quality defects are the main factors affecting product performance and service life. The paper explores the technical means of controlling quality defects through the analysis of key links in the production process. Firstly, the selection of raw materials and metallurgical quality have a direct impact on the internal and external defects of steel pipes, and the smelting and pretreatment processes of steel billets need to be strictly controlled. Secondly, uneven temperature and the formation of oxide scale during the heating process can lead to surface and internal defects in the steel pipe, therefore precise control of furnace temperature and atmosphere is required. Reasonable setting of rolling parameters and maintenance of equipment accuracy are crucial in the rolling process. Finally, optimization of cooling and heat treatment can effectively reduce residual stress and uneven microstructure, and improve the quality of steel pipes.
