Description
Technical Field
The utility model relates to a smelting device, in particular to a converter mouth structure.
Background
At the converter mouth, after the converter mouth bricks are built, the converter mouth bricks are poured and compacted by virtue of ladle mouth pouring materials, and the pouring materials fall off in the using process, so that the phenomenon that the converter mouth bricks fall off is caused. In a hot state, the furnace mouth can not be maintained, and the maintenance is needed after the furnace is shut down and cooled, so that the operation time of continuous steel making is delayed.
Disclosure of Invention
The utility model aims to solve the technical problem that a converter fire door structure is provided, improve the anti-oxidant and the erosion resistance at stove bottom turning, prevent that the fire door brick from dropping.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a converter fire door structure, converter fire door inside lining is built by laying bricks or stones by the fire door brick and is formed, be equipped with on the fire door inside lining of tapping side and visit the interior arc pushing off the slag lining of fire door, a plurality of furnace wall briquetting distributes at the circumference above the fire door inside lining, be equipped with a plurality of pushing off the slag lining briquetting above the pushing off the slag lining, furnace wall briquetting and pushing off the slag lining briquetting are the wedge, the outer edge and fire door flange fixed connection of furnace wall briquetting and pushing off the slag lining briquetting, furnace wall briquetting and pushing off the slag lining briquetting top are equipped with the castable coating, plane parallel and level on castable coating upper surface and the fire door flange.
The furnace lining pressing block is a wedge-shaped block from the inner edge of the furnace opening lining to the furnace opening flange from thick to thin.
The slag blocking lining pressing block is a wedge-shaped block which has the same thickness from the inner edge of the slag blocking lining to the inner edge of the furnace opening lining and is from thick to thin from the inner edge of the furnace opening lining to the furnace opening flange.
The furnace lining pressing block and the slag stopping lining pressing block are steel plates.
The distance between the furnace lining pressing block and the inner edge of the furnace mouth lining is 50-100 mm.
The distance between the slag blocking lining pressing block and the inner edge of the slag blocking lining is 50-100 mm.
The wedge angle of the lining pressing block and the slag stopping lining pressing block is 3-10 degrees.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure has the pushing off the slag effect, and the fire door brick is difficult for droing, avoids the slag to spill over from the fire door, need the problem of blowing out the maintenance after avoiding the fire door brick to drop. The service life of the converter is prolonged.
