Abstract
The method for repairing and mending of metallurgical furnace exhaust fume collecting hood side body of wall, comprises the following steps: 1, close with falling brick hole inside steel plate from the side body of wall, steel plate and side body of wall have inclination angle straight up; 2, by described Interal fixation on the shell steel construction of exhaust fume collecting hood; 3, be inclined upwardly at the exhaust fume collecting hood shell steel construction place falling brick hole mouth the multiple fixed block of welding; 4, to steel plate with fall filling and repairing material between brick hole, fixed block.The present invention repairs the side body of wall of metallurgical furnace exhaust fume collecting hood in hot state, and can repair exhaust fume collecting hood top interior wall at any time under smelting furnace normal running conditions, handling safety, cost is low.
Description
Technical field
The present invention relates to metallurgical furnace exhaust fume collecting hood body of wall method for repairing and mending, specifically the method for repairing and mending of a kind of metallurgical furnace exhaust fume collecting hood side body of wall.
Background technology
At present, a large amount of flue gases that metal smelt process produces generally are trapped by exhaust fume collecting hood, and surrounding sets up refractory brick material fire prevention interior wall to extend the service life of exhaust fume collecting hood inside exhaust fume collecting hood.Because in each stage of metal smelt, the flue gas temperature difference is larger, fire-proof wall surface and the inner existence because of differences in expansion, cause refractory brick marshalling inside to produce stress, will occur crackle when stress is accumulated to a certain degree, coming off of body of wall refractory brick causes brick hole.How for keeping normal production work, need the refractory brick to coming off to repair, but due under exhaust fume collecting hood is in the condition of high temperature in smelting process, be the technical barrier of this area in the repairing ensureing to carry out under metal smelt works normally exhaust fume collecting hood interior wall always.Traditional way stops producing, and carry out repair operation, but this body of wall repairing method cost is very high when exhaust fume collecting hood drops to room temperature.
Summary of the invention
The object of the present invention is to provide the method for repairing and mending of a kind of metallurgical furnace exhaust fume collecting hood side body of wall, it can solve exhaust fume collecting hood top interior wall under guarantee metal smelt works normally and repair the problem of difficulty.
The present invention is achieved through the following technical solutions above-mentioned purpose: the method for repairing and mending of metallurgical furnace exhaust fume collecting hood side body of wall, is in hot state to the operation that the side body of wall of metallurgical furnace exhaust fume collecting hood is repaired, comprises the following steps:
(1) close with falling brick hole inside steel plate from the side body of wall, steel plate and side body of wall have inclination angle straight up;
(2) by described Interal fixation on the shell steel construction of exhaust fume collecting hood;
(3) be inclined upwardly at the exhaust fume collecting hood shell steel construction place falling brick hole mouth the multiple fixed block of welding;
(4) to steel plate with fall filling and repairing material between brick hole, fixed block.
The size of brick hole is fallen described in the size of described steel plate is not less than.
Time implementation step (1), the steel plate first bottom being fixed with hanging wire stretches in metallurgical furnace exhaust fume collecting hood from falling brick hole, again hanging wire is upwards pullled, the position of adjustment steel plate makes steel plate close brick hole, steel plate lower limb is 60 ~ 100mm with the distance falling brick hole mouth, and the inclination angle of steel plate and side body of wall is 20 ° ~ 30 °.
Described Interal fixation on the shell steel construction of exhaust fume collecting hood be utilize welding steel bar method by described Interal fixation on the shell steel construction of metallurgical furnace exhaust fume collecting hood.
The length of described fixed block is 80 ~ 120mm, and fixed block inclination angle is upwards 20 ~ 30 °, and the spacing of adjacent fixed block is 100 ~ 150mm.
Described material for repairing is pouring material.
The present invention compared with prior art can repair exhaust fume collecting hood top interior wall at any time under smelting furnace normal running conditions, and handling safety, cost are low; By difform steel plate can to various fall brick hole repair, method for repairing and mending applicability is strong.
Accompanying drawing explanation
Fig. 1 (a) ~ (b) is for will falling the closed process chart of brick hole inside the present invention's steel plate from the side body of wall.
Fig. 2 is that the present invention is by the process chart of described Interal fixation on the shell steel construction of exhaust fume collecting hood.
Fig. 3 is that the present invention is inclined upwardly at the exhaust fume collecting hood shell steel construction place falling brick hole mouth and welds the process chart of multiple fixed block.
Fig. 4 is that the present invention is to steel plate and the process chart falling filling and repairing material between brick hole, fixed block.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail.
The present invention, by the method for repairing and mending of described metallurgical furnace exhaust fume collecting hood side body of wall, is in hot state to the operation that the side body of wall of metallurgical furnace exhaust fume collecting hood is repaired, comprises the following steps:
1, close with brick hole 5 will be fallen inside steel plate 3 from the side body of wall.As shown in Fig. 1 (a), Fig. 1 (b), first, difform steel plate 3 is made according to the situation falling brick hole 5, hanging wire 4 is fixed in steel plate 3 bottom, stretched in metallurgical furnace exhaust fume collecting hood from falling brick hole 5 by steel plate 3, then hanging wire 4 upwards pullled, the position of adjustment steel plate 3 makes steel plate 3 close brick hole 5, steel plate 3 lower limb is 60 ~ 100mm with the distance falling brick hole mouth 5, and steel plate 3 and side body of wall have the inclination angle of 20 ~ 30 °.For guaranteeing that steel plate 3 can seal completely by falling brick hole 5, the size of steel plate 3 is not less than to fall the size of brick hole 5.By difform steel plate 3 can to various fall brick hole 5 repair, this method for repairing and mending applicability is strong.
2, steel plate 3 is fixed on the shell steel construction 2 of exhaust fume collecting hood.As shown in Figure 2, in order to prevent steel plate 3 from dropping in follow-up repair procedure, welding steel bar 6 is utilized to be fixed on the shell steel construction 2 of metallurgical furnace exhaust fume collecting hood by steel plate 3;
3, as shown in Figure 3, be inclined upwardly at exhaust fume collecting hood shell steel construction 2 place falling brick hole mouth 5 the multiple fixed block 7 of welding, the length of fixed block 7 is 80 ~ 120mm, and makes fixed block 7 inclination angle upwards be 20 ~ 30 °, and the spacing of adjacent fixed block 7 is 100mm ~ 150mm.
4, as shown in Figure 4, to steel plate 3 with fall filling and repairing material 8 between brick hole 5, fixed block 7, material for repairing 8 is pouring material.
The present invention compared with prior art can repair exhaust fume collecting hood top interior wall at any time under smelting furnace normal running conditions, and handling safety is with low cost.
