How to improve desulphurization efficiency of refining slag

1. refining slag to be grinded (0.12 mm);

2., the injection rate should be in line with the [S] content. If the jet is too fast, the iron will appear unreacted particles on the water surface;

3., to prevent the slag from hot metal, the desulphurization efficiency can be reduced because the refining slag is easy to interact with MnO and FeO in the slag;

4。 to have a deeper depth of gun penetration;

5., considering the decomposition of refining slag, endothermic, low temperature and high viscosity of slag, it is necessary to maintain high hot metal temperature;

6。 [S] high sulphur content and good desulfurization effect, the unreacted refining slag slag will spread people less。

The advantage of desulphurization with refined slag is that the refining slag is cheap, the injection equipment is simple, and the desulfurization efficiency at high temperature (1400 DEG C) is relatively high
