Therefore, under the actions of expansion with heat and contraction with cold, melt scouring and the like after the opening of the horizontal converter, the furnace mouth falls off after the horizontal converter is used for a plurality of furnaces, the alloy furnace mouth is directly exposed to the high-temperature melt, so that the alloy furnace mouth is burnt, and even if the furnace lining body is intact, the furnace has to be stopped to repair the furnace mouth. Therefore, the traditional horizontal converter mouth and the masonry method have the problem that the service life of the mouth is not synchronous with that of the furnace body.

The invention adopts the following technical scheme:
a double-arch masonry structure for a lining in a furnace mouth area of a horizontal converter is characterized by comprising an inner ring arch (2) and an outer ring arch (3), wherein the outer ring arch (3) is masonry-constructed at the bottom of a furnace mouth (5) of the horizontal converter, the inner ring arch (2) is masonry-constructed at the bottom of the outer ring arch (3), the inner side of a furnace body of the horizontal converter is masonry-constructed with a circumferential cylinder brick layer through a plurality of cylinder bricks (1), and the inner ring arch (2) and the outer ring arch (3) are masonry-constructed with the circumferential cylinder brick layer through a plurality of locking bricks (4); the bottom of the inner ring arch (2) is built with a transition brick layer (6) through a plurality of barrel bricks (1), and the bottom of the transition brick layer (6) is flush with the inner side surface of the circumferential barrel brick layer.
According to the lining double-arch masonry structure of the horizontal converter mouth area, the inner ring arch (2) and the outer ring arch (3) are formed by combined masonry of shaped wedge-shaped bricks and standard bricks.
According to the lining masonry structure of the horizontal converter mouth area, the lining masonry structure is characterized in that the transition brick layer (6) is in masonry connection with the circumferential cylinder brick layer, and the middle part of the transition brick layer (6) is sunken compared with the masonry connection position of the transition brick layer (6) and the circumferential cylinder brick layer.
The invention has the beneficial technical effects that: the double-layer brick adopts a double-layer arch instead of a single-layer arch, so that the structural strength and the reliability are improved, the double-layer brick mainly has the functions of connecting the circumferential cylinder and the furnace mouth, and relatively separating and independently existing the circumferential cylinder and the furnace mouth, wherein the double-layer arch consists of an inner ring arch and an outer ring arch, and the inner ring arch and the outer ring arch independently exist and are integrated with the inner lining of the circumferential cylinder. The inner ring arch and the outer ring arch both adopt shaped wedge-shaped bricks and standard bricks instead of processed bricks, so that the dimensional accuracy and the structural strength are higher; the inner circular arch and the outer circular arch are built by combining and matching shaped wedge-shaped bricks and standard bricks, so that the size and radian of the arch are flexibly adjustable. The invention has good structural strength and high stability, is tightly combined with the lower transition brick layer and the circumferential cylinder brick layers at two sides, has large pressing force, is not easy to damage and has double insurance. The invention can prolong the service life of the furnace mouth of the horizontal converter, further improve the service life of the lining of the horizontal converter, and further provide powerful guarantee for the pyrometallurgical production of copper and nickel.
