Abstract

The invention belongs to the technical field of molten iron desulfurization, and discloses a molten iron desulfurization device and method. The molten iron desulfurization device comprises a blowing gas source, a stock bin, a conveying pipe, a desulfurization spray gun, a molten iron tank and a stirring paddle, the blowing air source is connected with the conveying pipe, and the stock bin is connected with the conveying pipe; the desulfurization spray gun is connected with the conveying pipe; the desulfurization spray gun is movably arranged in the molten iron tank; and the stirring paddle is arranged in the molten iron tank. The molten iron desulfurization device and method provided by the invention can greatly improve the dispersion degree and utilization rate of a desulfurizer.

Description

technical field [0001] The invention relates to the technical field of molten iron desulfurization, in particular to a molten iron desulfurization device and method. Background technique [0002] The traditional KR stirring process has the problem of low utilization rate of desulfurizer, and its actual amount is about 5-8 times of the theoretical amount. The main reason is: the silo is fed naturally or sprayed above the iron ladle; in the natural feeding method, the desulfurizer has a large block size and is easy to agglomerate, resulting in low utilization rate. Although the desulfurizer particle size is small in the injection method, it is easily affected. The air flow is disturbed and splashed, the proportion of desulfurizer actually entering the molten iron is relatively low, and the operating environment is harsh, which does not meet the environmental protection requirements; there is a large amount of desulfurizer gathered in the center of the stirring paddle, affected...
