Concast to Supply Two Minimills for Tianjin Iron & Steel
05/09/2007 - Tianjin Iron and Steel and Concast recently concluded a contract for the supply of two electric steelworks, including EAFs, a vacuum degasser, and continuous billet and bloom casters.
Tianjin Iron and Steel Co. Ltd., China, and Concast, Switzerland, recently concluded a contract for the supply of two electric steelworks.
Concast’s scope of supply for engineering and equipment includes two 110-tonne arc furnaces, two ladle furnaces, a vacuum degassing facility, continuous billet caster, and continuous bloom caster.
Although the arc furnaces will be designed to accept a charge of up to 40% hot metal, plans are also being made for an operating practice with 100% scrap, which would be loaded with a scrap bucket.
Both furnaces will be operated with 80-MVA transformers and Concast electrode positioning control with a SCAD (Slag Control and Detection) system. The furnaces will also be equipped with performance optimized CONSO systems for the introduction of chemical energy and for rapid decarburization.
Together, the two facilities will produce up to 2.25 million tonnes of crude steel. Steel will be cast either on the high-speed billet caster, with the section size 160 x 160 mm, or on the modern bloom caster, which can produce sizes up to 310-mm round. Both casters will be equipped with electromagnetic mold stirrers and Concast Convex® technology.
The two facilities will share a number of general plants and ancillary facilities. Commissioning is scheduled for 2008.
