TMK will upgrade pipe heat-treatment equipment at its Pervouralsk Pipe Plant (PNTZ) in Russia to reduce resource consumption and expand its size range of high-tech products. A roller-hearth furnace in a tube drawing shop has already been upgraded. The new technology allowed TMK to decrease the lower temperature limit in the furnace by 200C. The plant can now produce new products – ball bearings, precision and other pipes for the aerospace and automotive industries – with the mechanical properties required by Russian and European quality standards. As part of the upgrade, the furnace was equipped with a new digital process control system that runs a comprehensive equipment diagnostic and automatically adjusts the temperature parameters. PNTZ plans to upgrade two more furnaces in its tube drawing shops in 2021.
According to TMK, upgrading the heat-treatment equipment will reduce consumption of shielding and natural gas by up to two times, which will improve the plant’s environmental performance while bringing significant economic benefits.
