Fuxin Special Steel, Taiwan, has successfully commissioned a steelworks supplied by SMS Siemag for manufacturing stainless steel slabs at the Zhangzhou location in the Chinese Fujian Province. It is the first stainless steel plant in the world to utilise the waste heat from the AOD converter and the electric arc furnace. Fuxin Special Steel benefits from reducing emissions by 60,000 tons of CO2 per year.
The steelworks is equipped with an Ecoplants energy recovery system, utilising the thermal energy of the hot waste gases of more than 2,000°C from the EAF and AOD in order to produce steam. This steam is fed into the network and used for cooling electrical units, for example. The energy recovery systems provide around 36 tons of saturated steam per hour, which is fed into the steam network of the plant.
The range of grades produced by the steelworks comprises ferritic, austenitic and martensitic stainless steels, which are processed on the X-Cast continuous caster to provide slabs in thicknesses of 200mm or 220mm. During casting, the width can be set steplessly from 800mm to 1,600mm.
