Embodiment Construction

[0012] see figure 1 , a horizontal converter mouth lining masonry structure according to the present invention, comprising 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, The main function of the lining of the furnace mouth is to provide channels for the outflow of high-temperature melt and the escape of high-temperature flue gas; in terms of structure, the main function is to protect the furnace shell of the alloy furnace mouth. The furnace mouth of the horizontal converter is an alloy furnace mouth. The furnace mouth of the horizontal converter includes four inner sides. The other two inner sides opposite to the furnace mouth are built into a side wall brick layer by a plurality of side wall bricks 5, the bottom of the locking brick layer is flush with the bottom of the side wall brick layer, and the bottom of the locking brick layer is aligned with the s...

Abstract

The invention discloses a lining building structure of a horizontal converter mouth. The lining building structure comprises multiple transition bricks (1), multiple arch bricks (2), multiple lockingbricks (3), multiple tongue bricks (4) and multiple side wall bricks (5). The horizontal converter mouth comprises four inner side faces, two opposite inner side faces of the horizontal converter mouth are built into locking brick layers through the multiple locking bricks (3), and the other two opposite inner side faces of the horizontal converter mouth are built into side wall brick layers through the multiple side wall bricks (5). The bottoms of the locking brick layers are flush with the bottoms of the side wall brick layers, arch brick layers are built at the bottoms of the locking bricklayers and the bottoms of the side wall brick layers through the multiple arch bricks (2), and transition brick layers are built at the bottoms of the arch brick layers through the multiple transitionbricks (1). The locking bricks (3) are in building connection with the side wall bricks (5) through the tongue bricks (4). By means of the lining building structure of the horizontal converter mouth,the problems that a lining of the horizontal converter mouth is high in building difficulty, too fast in erosion, short in service life and the like can be solved.

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 lining masonry structure for a furnace mouth 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 t...
