Fuxin Special Steel Co. Ltd., Taiwan, has successfully commissioned a steelworks supplied by SMS Siemag www.sms-siemag.com 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 utilize 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 new construction project comprises a special steel plant, a continuous slab caster and environmental facilities for gas cleaning and energy recovery. The works is designed for a production of 720,000 tons of steel per year.

The X-Melt® steel plant consists of a 160-ton electric arc furnace with tapping spout, a 180-ton AOD-L converter and a 180-ton ladle furnace. The AOD converter is relined by means of a special changing car. The converter vessel is changed twice as quickly as with the conventional method, thus minimizing downtimes.

The steel plant satisfies stringent environmental protection standards. The primary emissions are extracted via cooled stacks and fed to two bag filters. The EAF and the AOD converter are provided with enclosures for efficient capture of the dust-laden secondary emissions. Additional dust produced will be captured and extracted.
