A high rolling force and a correspondingly high forming capacity characterize the four-high stand. The combination of a very large roll gap opening with the coaxial CVC^®plus system (Continuously Variable Crown) is a new development and allows the rolling stock to have an input thickness of up to 960 mm and thus an extremely large product range. To be able to process even short slabs, the heavy edging stand will be equipped with a newly developed support roller table.
The equipment will be designed to roll both, extreme casting block dimensions as well as small slab dimensions, down to plates. This will make production flexible and dynamic and ensure tightest geometrical tolerances. The maximum rolling force of the four-high reversing stand will be 109 MN in order to be able to reliably roll also special materials.
Designed for an annual production of 700,000 tons, the heavy-plate mill will produce plates between five and 120 mm thick and 1,550 to 4,200 mm wide.
The product range will include carbon steels, quality steels, low-alloy steels, grades for ship, bridge and pressure vessel construction, weather-proof and wear-resistant plates, pipe grades according to the API standard, as well as stainless steel and nickel-based materials.
With this rolling mill, Shanxi Taigang Stainless Steel will be able to cover a very wide range of products meeting the needs of infrastructure, chemical industry and shipbuilding and will therefore be well prepared for future requirements.
The heavy-plate mill is scheduled to start operating in mid-2022.
