Abstract:

This paper Remarks briefly on the development of Blast Furnace cooling techniques. It introduces the research results and application effects about the flow design, operation processing, the starting of operation, cooling water treatment technology, etc, of the cooling system of WISGCO No. 5 BF which is the first furnace to fully adopt the closed loop soft water circulating cooling method. Based on more than five yearsoperation results since BF began to work, w e evaluate the comprehensive benifits which result from adopting the closed loop soft w ter circulating cooling technig ues to leng then the furnace life, to improve the BF production and to economize on water supply and power energy. We suggest that this method should be popula ri zed and applied to other places according to the r respective actual condition so a s to improve the BF cooling technical competence of our country and obtain more benifits.
