During overhaul of the 2580 m3 BF in Angang by revamping, four old external combustion type hot blast stoves are kept and all refractory materials for these hot stoves are re-newed and therefore gas and air can be preheated to 180 ℃ by using the new-type and 19-hole grid brick with diameter 30 mm and plate heat exchanger. The production practice shows that the hot blast temperature from hot stoves can reach to 1 200℃and good results are achieved.
