en.Wedoany.com Reported - The world's first 5600mm ultra-wide heavy plate rolling mill, fully independently designed and supplied by MCC Capital Engineering & Research Incorporation Limited and manufactured under extreme conditions by CITIC Heavy Industries, has been operating continuously at full capacity since its successful hot load trial on October 31, 2024. Located in the heavy plate workshop of Zhoukou Iron and Steel, part of Henan Iron and Steel Group, this equipment—dubbed the "King of Rolling Mills"—enables Zhoukou Iron and Steel to achieve large-scale production of high-end ultra-wide steel plates, supplying in bulk to national strategic sectors such as shipbuilding, marine engineering, nuclear power, oil and gas, and large-scale water conservancy projects.
Founded in 1951 and headquartered in Beijing, MCC Capital Engineering & Research Incorporation Limited is a national team enterprise in China's metallurgical construction field, with decades of deep expertise in medium and heavy plate equipment design. It has successively achieved the localization of the full series of 3800mm and 4300mm rolling mills. Heavy plate rolling mills are indispensable core metallurgical equipment for the national economy and defense industry, with ultra-wide heavy plates directly supporting the manufacturing of national strategic assets such as aircraft carriers, large ocean-going vessels, offshore drilling platforms, and nuclear power plant containment vessels. Previously, all domestic 5000mm-class complete equipment relied entirely on imports, with key core technologies long monopolized by overseas enterprises, severely constraining China's independent supply capability for high-end specialty steel.
The MCC Capital research team visited frontline operations at major domestic steel enterprises, identified pain points in the actual operation of various rolling mills, and established a complete process system covering top-level design, mechanical simulation, 3D modeling, and finite element verification for the entire equipment set. The team independently developed proprietary rolling schedule calculation software, precisely calibrating core parameters such as rolling force, main motor power, and mill stand stiffness; they innovatively designed a complete set of structures including ultra-high stiffness integral cast mill stands, a high-speed electric screwdown plus hydraulic AGC composite control system, and multi-guide bending rolls, complemented by a full-process intelligent electrical control system.
From a global industrial layout perspective, there are approximately 31 completed or under-construction 5000mm-class heavy plate production lines worldwide, with only 7 in China. Data shows that in the first half of 2024, China's global shares in shipbuilding completions, new orders, and orders on hand reached 55%, 74.7%, and 58.9% respectively, securing over 70% of global green ship orders. Leading shipyards have order backlogs extending to 2028, with a long-term supply-demand gap for ultra-wide ship plates. This complete set of independently developed equipment technology by MCC Capital has completed a full-chain validation from R&D, manufacturing, installation and commissioning to market deployment, providing a benchmark example for China to break through the "bottleneck" of high-end metallurgical equipment.
