Abstract
The OxyCup plant at Tisco, Taiyuan, China, started operation as scheduled in June 2011. The plant was designed to process 600,000 tpy of self-reducing brick produced from dust and sludge residues together with approximately 100,000 tpy of pit scrap and skull. The plant layout includes a brick fabrication with material handling, mixing tower and curing hall. Two types of brick are produced in two different lines with residues from carbon steel production as well as from stainless steel production. Two individual operating OxyCup shaft furnaces are used to reduce and melt the brick and skull to liquid hot metal for Carbon steel and a liquid iron/ chromium/nickel alloy for stainless steel and slag according to the quality of the charge material respectively. The furnace top gases are de-dusted in a wet gas cleaning system and used for hot blast generation at the plant and electricity generation in a separate power plant on site. To increase the availability of the furnaces >8,000 hpy, a third furnace is installed to replace one of the other two in case of refractory repair and mechanical/electrical maintenance.
