In order to adapt to market needs, based on the related references and the experience of Tangshan Guofeng Iron and Steel Plate plant, the design aimed at the plate production. The main equipment of the workshop includes two 120t nominal capacity Top and Bottom of the oxygen-blown converters, two LF furnaces, two RH refining units and a hot metal desulphurization station. The different design idea and plans of the plant, as well as coordination with the auxiliary systems are compared and the plant unites are specficated. This plant has reached the advanced level of the average home and abroad. Designed systems include the hot metal supply, scrap supply, bulk material supply, ferroalloy supply, oxygen supply, flue gas clean, secondary refining and slag handling system. At the same time, the relevant parameters of each unite or system are being calculated. Main calculations include the converter furnace, the oxygen lance, the flue gas purification system, the calculation of workshop equipment and the calculation of cross-inter-span. In addition, slag splashing, hot metal pretreatment, secondary refining technologies, as well as the control of steel surface were taken to the international advanced level. The design finished the design specification paper, process plant layout drawing
