Embodiment Construction

[0021] In view of the technical problems in the prior art that it is difficult to replace the bottom blowing guns and the output of the converter is reduced when using the quick-change bottom blowing brick process, among the technical solutions proposed in the embodiments of the present invention, the technical solution of the present application is to obtain N groups of bottom blowing guns, And each bottom blow gun in the N groups of bottom blow guns is arranged on the bottom of the converter, because each group of bottom blow guns in the N groups of bottom blow guns includes at least 2 bottom blow guns with the same length, and The lengths of each two groups of bottom blow guns in the N groups of bottom blow guns are different, so that at the initial stage of the converter furnace life, the longer group of bottom blow guns in the N groups of bottom blow guns exerts the bottom blow effect, leaving at least A group of shorter bottom blowing guns are still buried in the bottom b...

Abstract

The invention discloses an arrangement method for bottom blowing guns of a converter and a top-bottom combined blowing converter. The method comprises the steps as follows: N groups of bottom blowing guns are obtained, and each bottom blowing gun of the N groups of bottom blowing guns is arranged at the bottom of the converter, wherein each group of bottom blowing guns of the N groups of bottom blowing guns at least comprises two bottom blowing guns with the same length, the lengths of every two groups of bottom blowing guns in the N groups of the bottom blowing guns are different, and the N is the integral number not less than 2. Through the adoption of the arrangement method, the simplifying technology can be realized, the yield of the converter can be improved, and the technical effect of better bottom blowing effect can also be realized.

Description

technical field [0001] The invention relates to the technical field of converter steelmaking, in particular to a method for arranging converter bottom blowing lances and a converter with combined top and bottom blowing. Background technique [0002] With the continuous development of iron and steel smelting technology, in the process of converter steelmaking, the converter bottom blow gun is placed in the furnace lining of the converter bottom. Good chemical reaction effect, thus improving the quality of steel. [0003] However, in the existing technology, in order to ensure the bottom blowing effect during the whole furnace service period, the technology of quick replacement of bottom blowing bricks is adopted. When it is difficult to ensure the ventilation effect of the bottom blowing bricks, the bottom blowing bricks are taken out by drilling, replaced with new ones, and sealed with fire mud. Before the bottom blowing of bricks, it is necessary to use the drilling proce...
