[Successful Resumption of Blast for Overhaul of No. 3 Hot Blast Stove at Chaoyang Iron and Steel Making Plant of Ansteel Group] Recently, the key period construction of the overhaul project for No. 3 hot blast stove at Chaoyang Iron and Steel Making Plant, contracted by Ansteel Engineering & Technology Corporation, was completed ahead of schedule, and the blast was resumed successfully.
The overhaul project for No. 3 hot blast stove at Chaoyang Iron and Steel Making Plant is the first domestic project to adopt a dual-stationary online top combustion modification scheme for both the furnace shell and the hot blast outlet. It transforms an internal combustion hot blast stove into a top combustion hot blast stove using a series of advanced technologies, including a catenary-shaped arch roof structure and efficient pressure-equalizing and flow-equalizing checker bricks.
