Embodiment Construction

[0011] see Figure 1-2 , a double-arch masonry structure lining the furnace mouth area of ​​a horizontal converter according to the present invention, comprising an inner ring arch 2 and an outer ring arch 3, the outer ring arch 3 is built at the bottom of the furnace mouth 5 of the horizontal converter, and the inner ring arch 2 is built on the bottom of the outer ring arch 3, and the inside of the horizontal converter body passes through a plurality of cylinder bricks 1 to build the circumferential cylinder brick layer, and both the inner ring arch 2 and the outer ring arch 3 pass through multiple cylinder brick layers. Two lock bricks 4 are connected by masonry; the bottom of the inner ring arch 2 is built with a plurality of cylinder bricks 1 to build a transition brick layer 6, and the bottom of the transition brick layer 6 is flush with the inner surface of the circumferential cylinder brick layer. The transition brick layer 6 is connected with the circumferential cylind...

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.

Description

technical field [0001] The invention belongs to the technical field of horizontal converters for blowing copper matte and nickel matte, and in particular relates to a double-arch masonry structure lining the furnace mouth area of ​​a horizontal converter. Background technique [0002] The lining of the mouth of the traditional horizontal converter for copper-nickel converting is made of simple side-laying of refractory bricks or a single-layer masonry structure similar to a flat arch by adding ash joints. The masonry structure has low strength and poor reliability, and it is not well combined with the two sides and the lower circumferential lining, and does not form a separate force-bearing structure. Therefore, under the effects of thermal expansion and contraction and melt erosion after the horizontal converter is opened, the furnace mouth will fall off after several furnaces are used, and the alloy furnace mouth is directly exposed to the high-temperature melt, causing th...
