The 90t EAF at VKS plant in Vietnam triumphed over the once hot test run and smelted the qualified liquid steel. It was an EPC-based Mini-Mill project undertaken by Japan’s SPCO in an annual target of 500,000t billets of low carbon and alloyed steel. SPCO entrusted Electric Furnace Institute (EFI), a subsidiary in Xi’an under CISDI Group, for shouldering the detail design, package supply, and technical assistance and commissioning services. The meltshop contains 1x90t/64MVA EAF, 1x90t/14MVA LF, 1xfully-automatic alloy charge system, 1x180,000Nm³/h dedusting system, and other auxiliaries (stock basket, ladle, ladle car) and EIC (HV, LV and automation control) system. All the design drawings should be delivered in 3D making and SPCO’s specified format; all the manufacture and inspection of equipment should be executed in accordance with SPCO’s standards.
