Abstract

In 2012, NLMK DanSteel put a new 4200-mm plate mill into operation, which will allow the company to expand the dimensional range of thick plates and to ensure the production of promising grades of thick plates for off shore structures, the wind energy sector and the pipe industry. The article contains technical characteristics of the new equipment at the enterprise (heat treatment walking beam furnace, 4200 rolling stand, automation systems) and description of technological capabilities of the 4200-mm hot rolling mill in the production of hot-rolled plates of low carbon steels. The construction of the new 4 200-mm plate mill at NLMK DanSteel A/S enhanced competitiveness of products and contributed to expansion of the mix as regards dimensions of plates and steel grades, for example, production of wide plates with varying thicknesses from 5 to 200 mm. Modern technologies including normalizing technology, thermo-mechanical rolling and heat treatment by normalization make it possible to produce high quality structural steel that is used for shipbuilding, machinery, bridge construction, pressure vessels, boilers, wind turbines and off shore structures. Production of plates with thicknesses of more than 60 mm, yield strength of more than 450 N/mm2 and impact strength of more than 150 J at −50 °C is the priority development of the technical and technological capacity of the rolling complex.
