The continuous rolling pipe unit uses continuous casting billets to efficiently produce seamless steel pipes. Its production process is different from the traditional rolling process, and the defects (deficiencies) produced are also different. The causes of the main defects of continuous rolling steel pipes are analyzed. Based on this, each link of production operation, technical supervision, and production technology management can accurately judge the product quality, determine the causes of defects, control the defects of this process, and ultimately improve the quality of steel pipe products.
In the past, many experts and scholars have written books on the defects (deficiencies) of hot-rolled seamless steel pipe products. However, these discussions are mainly aimed at traditional rolling pipe units such as automatic rolling pipe units and periodic rolling pipe units. Since the reform and opening up, with the introduction and construction of continuous rolling pipe units and the use of continuous casting billets instead of rolling billets as raw materials for efficient seamless steel pipe production processes, continuous rolling pipe units have become the main force in the production of hot-rolled seamless steel pipes. Since this production process is very different from the traditional production process, the product defects produced are also different. Research and analysis of these product defects can not only guide on-site production, reduce waste, and improve the yield rate, but also help to understand the process characteristics of continuous rolling pipe units.
The purpose of discussing the defects (deficiencies) that are easy to occur in the process of producing seamless steel pipes by continuous rolling mills is to explore how to strictly control product quality in actual production, to facilitate production operators, technical supervisors, and production technicians to accurately judge product quality at work and find out the causes of defects, to eliminate defects in the main process and provide high-quality products to the next main process (users), and finally achieve the purpose of improving the quality of steel pipe products.
