Technology Progress on High Blast Temperature of Hot Blast Stove in Shougang
Present state and technology progress of hot blast stove in Shougang is narrated, so the developing direction of BF stove in Shougang is large type and high blast temperature. By analyzing the change of blast temperature in Beijing area, Shouqin and Qiangang Company since BF stove is put into production, BF stove with BF gas burnt in Shougang can reach its blast temperature to 1250℃ by using high temperature air combustion. Flow field and temperature distributing of different BF stove in Shougang are studied by simulation and cold test, and the questions of top and inner combustion type are found. High blast temperature can be reached between 1250 and 1280℃ by enhancing system line watch﹑optimizing operating system and improving the condition of material and fuel in Shougang. The methods will be carried out on No.3 blast furnace in Qiangang Company and the large blast furnace in Jingtang Company. It can also offer reference for the study of high blast temperature of domestic and overseas BF.
