Abstract Requirements for the process of pipe production operations, which reduce the formation of hard-to-remove scale on internal surface, have been developed. According to the study results of chemical reaction features of deoxidizing materials with scale on the internal shell surface, these requirements are based on the flow process analysis of the production of seamless hot-rolled pipes in the lines of contemporary pipe-rolling plants with mandrel mills and in heat treatment areas. A series of experimental pipe rolling has been carried out on the plants of PAO TMK using the INCOAT technology and equipment of SMS group Company (Germany). The results of the work have confirmed the inhibition effectiveness of active scale formation on the internal shell surface through combination of piercing and treatment of the internal shell surface with deoxidizing material.

无缝热轧管内表面氧化皮的最小化

摘要 管材生产过程中减少内表面难以去除的水垢形成的要求已得到发展。根据对内壳表面带有氧化皮的脱氧材料化学反应特征的研究结果,这些要求是基于对现代管材轧管厂生产线生产无缝热轧管的流程分析得出的。和热处理领域。使用西马克集团公司(德国)的 INCOAT 技术和设备,在 PAO TMK 的设备上进行了一系列的轧管试验。
