Fig. 1 is a schematic structural view of the present invention.
Detailed Description
Referring to fig. 1, the lining masonry structure for the horizontal converter mouth comprises a plurality of transition bricks 1, a plurality of arch bricks 2, a plurality of locking bricks 3, a plurality of tongue bricks 4 and a plurality of side wall bricks 5, wherein the lining of the converter mouth mainly plays a role in providing a high-temperature melt outflow channel and a high-temperature flue gas escape channel in the process; the structure mainly plays a role in protecting the furnace shell of the alloy furnace mouth. The horizontal converter fire door is the alloy fire door, the horizontal converter fire door includes four medial surfaces, two relative medial surfaces of horizontal converter fire door build into the locking brick layer through a plurality of locking bricks 3, two other medial surfaces of horizontal converter fire door are built into the side wall brick layer through a plurality of side wall bricks 5, the bottom on locking brick layer flushes with the bottom on side wall brick layer, the bottom on locking brick layer and the bottom on side wall brick layer build the hunch brick layer through a plurality of hunch bricks 2, the number of piles on hunch brick layer is two-layer, and the intensity and the reliability are improved, realize the smooth transition from the circumference barrel to the fire door, hunch brick and circumference handing-over department are the locking brick, play the effect of hunch foot brick. The bottom of the arch brick layer is built with a transition brick layer through a plurality of transition bricks 1; the cross section size of the arch brick layer is larger than that of the locking brick layer and that of the side wall brick layer; the size of the cross section of the transition brick layer is larger than that of the arch brick layer. The transition brick 1 is a shaped brick, not a processed brick, and the shaped brick is a non-cuboid brick of various special-shaped bricks which are customized from a refractory material manufacturer according to the building requirement of a special part and are fired by a special mould; the shaped brick does not need to be cut by a cutter, so that the shaped brick is not subjected to mechanical damage, has no cutting surface, and has better integrity, higher strength and better high-temperature resistance. The locking bricks 3 and the side wall bricks 5 are connected by masonry through the tongue bricks 4. Magnesium-chromium filler with the thickness of 20mm-30mm is laid between the masonry structure and the furnace shell of the horizontal converter, the filler plays roles of absorbing expansion and a safety layer, slag is favorably hung after the brick body is corroded and falls off, and a slag protective layer is formed to protect an alloy furnace mouth. The tongue brick is tightly attached to the arch brick to realize the joint of the tongue brick of the circumferential lining body, and the connecting part of the tongue brick can be regarded as the intersecting line of two cylinders.
