The utility model discloses a novel converter center
brick and bottom blowing structure, and relates to the technical field of converter linings, the novel converter center
brick and bottom blowing structure comprises a converter, a center
brick is arranged at the center position of the bottom in the converter, and a bundling
pipe is pre-buried in the center brick; a plurality of bottom blowing bricks are arranged at the bottom in the converter at equal intervals in a circular array mode with the center brick as the center point, a cover plate is arranged at the top of the converter, an
exhaust pipe is connected to the cover plate, the end, away from the cover plate, of the
exhaust pipe is connected with a gas box, and the end, close to the cover plate, of the
exhaust pipe is connected with a valve. A main
discharge pipe is arranged on the side, away from the exhaust
pipe, of the gas tank, filters are arranged at the two ends of the side, close to the gas tank, of the main
discharge pipe, and a bundling pipe is pre-buried in a center brick, so that the blowing
smelting function and a specific bottom blowing distribution mode can be achieved,
molten steel components can be more uniform, the blowing time is obviously shortened, and the yield is obviously increased; and converter end point carbon-
oxygen deposition is reduced, and the index is stable.
