(hereinafter referred to as Anshan Iron and Steel Engineering and Yuxing Engineering) jointly designed and constructed the project to successfully transform Chaoyang Iron and Steel's original internal combustion hot blast stove into a catenary top-fired hot blast stove using online transformation technology in which the original hot blast stove shell and hot air outlet elevation are fixed.

Top-fired hot blast stoves have been introduced into my country in 2003 and have been developed.
