At the end of 2020, NLMK Verona has placed an order with Tenova for the turnkey supply of a 70 tonne VOD plant, with level 1 & 2 automation, deslagging machine and auxiliary equipment. The scope of the contract includes engineering, supply, erection of all equipment, supervision of erection, commissioning and training. The new VOD plant will expand the existing production route, which currently includes an electric arc furnace, two ladle furnaces, a vacuum degassing system, a continuous casting plant, and an ingot casting plant.
The increasing demand for high quality steel makes the vacuum treatment an essential step in secondary metallurgy process. Tenova Vacuum Degasser units VD VOD feature effective removal of hydrogen, oxygen and or carbon, based on proven technology and experience. The new VD VOD plant will in fact increase the overall production rate of vacuum treated steel and the product range of VOD treated steel. Moreover, thanks to new deslagging machine and the vacuum treatment, the steel quality of the final products will improve, allowing NLMK to increase the range of quality steel already supplied.
