At present, domestic steel mill ladle is with the service life of air brick generally at 20-30 times, and monoblock type air brick will carry out cold repair and change air brick, and split type air brick will carry out heat 20-25 left and right and change porous core operation, ventilating seat brick service life 40-50 times.When heat is changed porous core, while changing a new porous core exactly under hot situation, now ventilating seat brick is not changed; Heat is changed after porous core, ventilating seat brick height is lower than porous core height, cause the position of protruding ventilating seat brick directly to contact molten steel, in use procedure, generally the first stove just washes away fracture along ventilating seat brick upper surface, causing changing rear porous core does not reach 20 times service life, general 10 left and right are just forced to the maintenance of rolling off the production line, and have larger potential safety hazard, the service life of having reduced porous core and ventilating seat brick.
Summary of the invention
The utility model provides this kind of ladle ventilating seat brick hot patching device according to the deficiencies in the prior art, this device is directly repaired ventilating seat brick after heat is changed porous core under hot environment, make the height of ventilating seat brick concordant with porous core, solution heat is changed rear molten steel the first stove and porous core is washed away to the difficult point of fracture, reach the life-span of improving air brick, reduce costs, improve the object of safe handling coefficient.
The technical scheme that the utility model provides: described a kind of ladle ventilating seat brick hot patching device comprises aloft work platform, a side at aloft work platform is provided with stair, it is characterized in that: on aloft work platform, be provided with one and repair platform, the one end of repairing platform is fixed on the table top of aloft work platform by rotation seat, at the other end of repairing platform, be provided with the bearing being connected with the lifting steel wire of hoist engine, on repairing platform, offer the repairing hole that diameter is 250-350mm; Described repair apparatus also comprises at least two ladle positioning seats, when described ladle positioning seat is arranged on and repairs platform and become level under, and ladle by ladle positioning seat location after, repair hole over against ladle ventilating seat brick.
The further technical scheme of the utility model: described repairing platform is round table surface, is equipped with non-floating rail in the repairing outer rim of platform and the outer rim of work high above the ground platform upper table surface.
Described ladle positioning seat has four, and four ladle positioning seats equidistantly arrange the outer rim of ladle bottom, and distance and ladle bottom equal diameters between two non-conterminous ladle positioning seats.
Described repairing hole is 300mm.
The beneficial effects of the utility model:
1, the utility model can be repaired ventilating seat brick in the situation of high temperature, has improved ladle hot turnover rate, has reduced baking energy cost.
2, after using the utility model to the hot lower repairing of ladle ventilating seat brick, just can extend the service life of ventilating seat brick and porous core, extend ventilating seat brick and porous core life-span 3-5 times, reduce ventilating seat brick and porous core cost 15%;
3, the utility model in use, ventilate all the time by porous core, can reduce the phenomenon that porous core is stopped up by residual steel, material;
4, the utility model is reasonable in design, can be by the position of measuring air brick of ladle registration, and operating process is simple, convenient, practical.
