Isothermal Experimental Study on the Effects of Converter Bath Shape on the Melt Mixing

Abstract:

The effects of the bath shape, oxygen lance nozzles structure, and lance level on liquid steel mixing time and splashing amount were studied by experiment orthogonal design with 1:10 water model for 100 t basic oxygen converter modeling. The results showed that the stirring effect in the bath can be improved by changing the shape on the bath surface around the furnace wall with arc-shaped structure which can shorten the mixing time and reduce the liquid slag and steel splashing amount of the lining, and result in reducing metal lose and prolong the life of the lining.
