Abstract
The utility model discloses a molten pool smelting furnace with double reverse arcs and belongs to the technical field of molten pool smelting furnaces. The molten pool smelting furnace with the double reverse arcs comprises a furnace bottom. The furnace bottom is composed of a first reverse arc and a second reverse arc. The first reverse arc is located on the upper portion of the second reverse arc, the first reverse arc is formed by semi-rebonded magnesia-chrome bricks being constructed, the second reverse arc is formed by direct-bonded magnesia-chrome bricks being constructed, and staggered joint construction is adopted between the first reverse arc and the second reverse arc. A double reverse arc structure of the first reverse arc and the second reverse arc is adopted in the furnace bottom, at the same time straight joints cannot be formed, and the bricks of the first reverse arc and the second reverse arc are constructed in a staggered joint mode. The molten pool smelting furnace with the double reverse arcs with the structure improves the corrosion resistant capacity and the scouring resistant capacity of the furnace bottom of the molten pool smelting furnace, and effectively prolongs the service life of the molten pool smelting furnace.
Description
Technical field
The utility model belongs to the bath smelting furnace technical field, specifically a kind of pair of antiarch bath smelting furnace.
Background technology
Bath smelting is furnace charge directly to be added finish rapidly the method for smelting that gas, liquid, solid equate key reaction in the molten bath that air blast seethes.Bath smelting furnace is divided into smelting zone and settling zone with the partition wall passage with stove, enter stove material and oxygen-enriched air behind the process physical-chemical reaction of series of complex of smelting zone, the smelting zone melt enters the settling zone through the partition wall passage and carries out separating of slag and molten metal, thereby finishes the fusion process of metal concentrate.The brick furnace bottom of present bath smelting furnace generally adopts antiarch to build by laying bricks or stones, and the antiarch angle is 20-45 °, makes the fragment of brick floating to prevent melt infiltration.The material of brick furnace bottom, from the bottom to top: it is low that cast iron plate or steel plate 10-50mm(are used for built on stilts stove), asbestos board 10-20mm, clay brick 230 or 340mm, ramming layer 60-150mm, magnesia brick or magnesia-alumina brick 380 or 460mm.But the melt of the bath smelting furnace of this structure is more serious to washing away of furnace bottom antiarch, and the service life of furnace bottom is shorter.
The utility model content
Technical problem to be solved in the utility model is in order to overcome shorter shortcoming and provide that a kind of corrosion-resistant abrasion resistance is strong, two antiarch bath smelting furnaces of long working life in service life of furnace bottom in the prior art.
Adopt following technical scheme for solving technical problem of the present utility model:
A kind of pair of antiarch bath smelting furnace, comprise furnace bottom, described furnace bottom is comprised of the first antiarch and the second antiarch, described the first antiarch is positioned at the second antiarch top, described the first antiarch is built by laying bricks or stones by Semi bonded magnesia chrome brick and is formed, described the second antiarch forms by directly building by laying bricks or stones in conjunction with magnesite-chrome brick, and the fissure of displacement is built by laying bricks or stones between described the first antiarch and the second antiarch.
Described the second antiarch be 230 ㎜ in conjunction with magnesite-chrome brick thickness directly.
Furnace bottom of the present utility model has adopted two antiarch structures of the first antiarch and the second antiarch, and simultaneously in order not form straight joint, the brick fissure of displacement of the first antiarch and the second antiarch is built by laying bricks or stones.Two antiarch bath smelting furnaces of this structure have improved corrosion-resistant, the abrasion resistance of bath smelting furnace furnace bottom, have effectively increased the working life of bath smelting furnace.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of pair of antiarch bath smelting furnace comprises furnace bottom, and furnace bottom is comprised of the first antiarch 1 and the second antiarch 2.The first antiarch 1 is positioned at the second antiarch 2 tops.The first antiarch 1 is built by laying bricks or stones by Semi bonded magnesia chrome brick and is formed, and the second antiarch 2 forms by directly building by laying bricks or stones in conjunction with magnesite-chrome brick, the second antiarch 2 be 230 ㎜ in conjunction with magnesite-chrome brick thickness directly.The fissure of displacement is built by laying bricks or stones between the first antiarch 1 and the second antiarch 2.Furnace bottom of the present utility model has adopted two antiarch structures of the first antiarch 1 and the second antiarch 2, and simultaneously in order not form straight joint, the brick fissure of displacement of the first antiarch 1 and the second antiarch 2 is built by laying bricks or stones.Two antiarch bath smelting furnaces of this structure have improved corrosion-resistant, the abrasion resistance of bath smelting furnace furnace bottom, have effectively increased the working life of bath smelting furnace.
Claims (2)
1. two antiarch bath smelting furnace, comprise furnace bottom, it is characterized in that: described furnace bottom is comprised of the first antiarch (1) and the second antiarch (2), described the first antiarch (1) is positioned at the second antiarch (2) top, described the first antiarch (1) is built by laying bricks or stones by Semi bonded magnesia chrome brick and is formed, described the second antiarch (2) forms by directly building by laying bricks or stones in conjunction with magnesite-chrome brick, and the fissure of displacement is built by laying bricks or stones between described the first antiarch (1) and the second antiarch (2).
