Abstract：Rich oxygen top-blown furnace is widely used in nonferrous metallurgy, however, so far the spray lance position has been difficult to be measured online, and it affects the control and life of spray lance. In order to improve the life and production efficiency of spray lance, based on soft prediction model of spray lance's position and fuzzy control algorithm of spray lance end-pressure which gained, the data exchange between soft measurement algorithm of spray lance position in Matlab based on OPC and WinCC platform are achieved successfully. And the lance position and predicted values of spray lance's insertion depth are highlighted on WinCC interface, it solve the problem that the spray lanc position is hard to measure online, and thus the life of the spray lance is improved. The spray lance average life under the traditional measure is 79.6 h, the average life under soft measured is reached 155.28 h.
