Lining building structure for horizontal converter mouth area

Abstract

The invention discloses a lining building structure for a horizontal converter mouth area. The lining building structure for the horizontal converter mouth area comprises multiple transition bricks (1), multiple arch bricks (2), multiple locking bricks (3), multiple tongue bricks (4) and multiple side wall bricks (5). The multiple tongue bricks (4) are built into a tongue brick layer, and the tongue brick layer is in building connection with the inner side face of a horizontal converter mouth through the multiple side wall bricks (5). An arch brick layer is built at the bottom of the tongue brick layer through the multiple arch bricks (2). A cylinder brick layer is built on the inner side of a horizontal converter body (6) through multiple cylinder bricks (7). The arch brick layer is connected with the cylinder brick layer through the multiple locking bricks (3). A transition brick layer is built at the bottom of the arch brick layer through the multiple transition bricks (1) and is inbuilding connection with the cylinder brick layer. By means of the lining building structure for the horizontal converter mouth area. The problems that in the prior art, a lining of the horizontal converter mouth area is large in building difficulty, too fast in erosion and short in service life can be solved.

Description

technical field [0001] The invention belongs to the technical field of horizontal converter structures, and in particular relates to a lining masonry structure in the furnace mouth area of ​​a horizontal converter. Background technique [0002] The furnace mouth of the traditional horizontal converter for copper-nickel converting is made of alloy furnace mouth or water jacket, and the surface of the alloy furnace mouth or water jacket is simply piled up with refractory castables or refractory bricks. The alloy furnace mouth is not resistant to high-temperature melt erosion and has a short service life, while the water jacket has hidden dangers of water leakage. The simple stacking structure of refractory bricks has a short service life, and the furnace mouth is only protected during the furnace opening stage. After several blowing furnaces, due to the lack of structural stability, they all fall off, and the alloy furnace mouth is directly exposed to the high-temperature melt...
