Fuxin Special Steel Co. Ltd., China Taiwan, successfully commissioned a steelworks for stainless steel slabs supplied by SMS group to the Zhangzhou location in Fujian Province, China. This is the world's first stainless steel plant to utilize the waste heat from the AOD converter and the electric-arc furnace. That slashes emissions by a massive 60,000 t of CO2 per year.
The X-Melt® steel plant consists of a 160-t electric arc-furnace with tapping spout, a 180-t AOD-L converter, and a 180-t ladle furnace. Integrated here is a special changing car for relining the AOD converter. Compared to the conventional method, changing the converter vessel is twice as fast. That drastically cuts downtimes.
The steel plant meets even the toughest environmental protection standards. Here is how: The primary emissions go through cooled stacks and into two bag filters. To ensure efficient capture of the dustladen secondary emissions, the EAF and the AOD converter feature special enclosures. Any additional dust produced is also captured and extracted. Outstanding here is that the filters of the gas cleaning systems are designed for more than 2.3 million cubic meters of air per hour.
