| Abstract: | In Henan Jiyuan Iron and Steel （Group） Co. , Ltd. , the natural gas is used in the refining process of RH vacuum furnace to heat the refractory and snorkel. Since the cost of natural gas is high and the natural gas usage in this aspect does not meet nation＇s energy policy, the technical transformation for three online roaster and one offline roaster were executed with the regenerative heating technology, in which long blaze regenerative composite burner, oriented fan, blower and commutation system were used. Of cause, a blower pipe was add- ed. The control of the oriented wind and commutation system was realized. After reforming, the facilities run stably, meet demands of production, and realize the reduction of cost and energy consumption. |
