Abstract

The invention discloses a lining double-arch masonry structure in a mouth area of a horizontal converter. The structure comprises an inner ring arch (2) and an outer ring arch (3), the outer ring arch(3) is built at the bottom of a horizontal converter mouth (5), the inner ring arch (2) is built at the bottom of the outer ring arch (3), a circumferential cylinder brick layer is built on the innerside of a horizontal converter body through a plurality of cylinder bricks (1), and the inner ring arch (2) and the outer ring arch (3) are in masonry connection with the circumferential cylinder brick layer through a plurality of lock bricks (4). A transition brick layer (6) is built at the bottom of the inner ring arch (2) through the cylinder bricks (1), and the bottom of the transition bricklayer (6) is flush with the inner side face of the circumferential cylinder brick layer. The structure can improve the operation rate of the converter and prolongs the service life of the converter.

Example Embodiment

[0011] See Figure 1-2 , A horizontal converter furnace mouth area lining double-arch masonry structure of the present invention includes an inner ring arch 2 and an outer ring arch 3, the outer ring arch 3 is built on the bottom of the horizontal converter furnace mouth 5, and the inner ring arch 2 Masonry is at the bottom of the outer ring arch 3, the inner side of the horizontal converter body passes through a plurality of cylinder bricks. 1 The circumferential cylinder brick layer is built, and the inner ring arch 2 and the outer ring arch 3 both pass through the circumferential cylinder brick layer. The two lock bricks 4 are connected by masonry; the bottom of the inner ring arch 2 is built with a transition brick layer 6 through a plurality of cylindrical bricks 1, and the bottom of the transition brick layer 6 is flush with the inner side of the circumferential cylindrical brick layer. The transition brick layer 6 is masonry connected with the circumferential tube brick layer, and the middle part of the transition brick layer 6 is recessed compared to the masonry connection between the transition brick layer 6 and the circumferential tube brick layer. Both the inner ring arch 2 and the outer ring arch 3 are formed by combining fixed wedge bricks and standard bricks. Shaped bricks are customized from refractory manufacturers and fired with special molds and non-cubic bricks according to the masonry needs of special parts; stereotyped bricks do not need to be cuboid bricks to be cut with a cutting machine, so there is no mechanical damage. Cutting surface, better integrity, higher strength, better high temperature resistance.
[0012] The lining of the entire horizontal converter can be roughly divided into the end wall, the circumferential cylinder and the furnace mouth. The furnace mouth is the most difficult part of the horizontal converter. When laying horizontal converters, first build the end wall, then use the rotating masonry method to build the circular cylinder, and then the circular masonry is built to the radius, and the furnace mouth area lining is synchronously built. The specific masonry steps are as follows:
[0013] (1) Lay the brick layer of the circumferential cylinder to below the furnace mouth of the horizontal converter;
[0014] (2) Use standard bricks to locate the center bricks of the inner ring arch, build the center bricks of the inner ring arch, and pre-lay the standard bricks and shaped wedge-shaped bricks according to the size and curvature of the furnace mouth. According to the pre-masonry situation, start from the center on both sides. Masonry inner ring arch;
[0015] (3) When the inner ring arch is masonry, the cylinder bricks on both sides of the circumference shall be simultaneously laid. After the inner ring arch is built, the inner ring arch lock bricks shall be built and joint with the circumferential cylinder bricks on both sides;
[0016] (4) Measure and visually inspect the size and radian of the inner ring arch to confirm that it is correct and start to build the outer ring arch;
[0017] (5) Use standard bricks to locate the center bricks of the outer ring arch at the center of the inner ring arch and stagger the brick joints. Build the center bricks of the outer ring arch. Pre-lay the standard bricks and wedge-shaped bricks according to the furnace mouth size and curvature. The construction situation is corresponding to the outer ring arch on both sides from the center;
[0018] (6) When the outer ring arch is masonry, simultaneous masonry of cylindrical bricks on both sides of the circumference, after the completion of the outer ring arch masonry, the outer ring arch lock bricks are laid, and the joints with the circumferential cylindrical bricks on both sides;
[0019] (7) Measure and visually inspect the inner ring arch size and radian to confirm that it matches the furnace mouth size.
