Description
Technical field
The utility model belongs to the specific purpose tool, particularly a kind of quick replacement device of ladle nozzle brick that ladle nozzle brick is changed in steel mill steel-making.
Background technology
Ladle is a kind of outside box hat, inner high-temp liquid splendid attire by laying fireproof bricks, transport, smelting vessel.The casting of molten steel is that molten steel is put into tundish and cast by the magnesium carbonaceous mouth of a river of being installed by ladle bottom, but the magnesium carbonaceous mouth of a river is after use is to the 15th time, and internal diameter expanding phenomenon in the mouth of a river is serious, easily cause Bao Di mechanism to wear steel, after must changing it, this ladle can be reused.Former technique is after being set level by ladle, in ladle nozzle, fill in rock wool carry out shutoff, then use water pipe to insert in the magnesium carbonaceous mouth of a river to lower the temperature to it, 30 minutes at least consuming time of this process of fetching water, be down to after below 100 DEG C from 1000 DEG C Deng mouth of a river temperature, the old mouth of a river and the fire clay remained in pocket block are smashed, are drawn out by artificial use pneumatic pick, 15 minutes consuming time of this process, 10 minutes consuming time of the assembling at the last new mouth of a river.Former replacing mouth of a river technique is on average consuming time is 1h, and due to consuming time longer, ladle is long for standing time, temperature drop is large, more to the loss of front operation (converter) tapping temperature, rear operation (refining) temperature raising is also comparatively difficult, causes very adverse influence in a word to whole rhythm of production.
Summary of the invention
The purpose of this utility model is the quick replacement device providing a kind of ladle nozzle brick, it is rational in infrastructure, easy to operate, at high operating temperatures can fast by nozzle brick overall pull-out in steel base brick, reduce former cooling of fetching water, the operation of the broken nozzle brick of pneumatic pick, saves the time of changing nozzle brick, accelerate the heat turnover of ladle, reduce production cost.
The purpose of this utility model is achieved in that a kind of quick replacement device of ladle nozzle brick, surface arranges threaded stud, the articulated uniform gad of its conical head, the block that stud head in gad front portion is arranged is by spacing for the gad launched, the length of gad is greater than the radius at the nozzle brick mouth of a river, on the stud being positioned at gad rear portion, dynamic cooperation is installed with movable steel sleeve pipe, match with uniform hinged gad in the front end of movable steel sleeve pipe, the stud stretching out movable steel sleeve pipe coordinates the first thread bush being evenly equipped with boosting-rod is installed, the carrier base bore being evenly equipped with supporting leg coordinates with the stud at the first screw-casing rear portion is dynamic, the stud being positioned at carrier base outside coordinates the second screw-casing being evenly equipped with boosting-rod is installed.
Ladle nozzle brick is a kind of high temperature resistant resistant to corrosion, the cylindrical object that material is hard, it is arranged on pocket block endoporus by the sintering of chamotte, when reaching certain life-span, mouth of a river internal diameter can expand, need to change, Renewal process is comparatively loaded down with trivial details, first water pipe cooling on probation, mouth of a river entirety smashes by rear use pneumatic pick, and brick cup inner wall cleaning is clean after the new mouth of a river can be installed, consuming time very long, the object of this invention is to accelerate outlet replacing speed, improve the turnover rate of red heat ladle, concrete implementing measure is as follows: first, this device is made up of four parts, 1 respectively, movable gad band full screw thread stud is equipped with in end, 2, movable steel pipe box, 3 mechanism racks, 4, first of the interior screw thread of band, second screw-casing.This device use principle is as follows: 1, is enclosed within by movable steel pipe on band male thread stud, stud entirety is stretched in the red heat mouth of a river, promote steel pipe socket, make its other end and gad dieback to gad cannot continue to expand.2, use the first screw-casing with screw thread to be screwed into, owing to being subject to the thrust of the first screw-casing, movable steel pipe box continues to push ahead, and finally makes gad be expanded to and overall inserts nozzle brick inwall, make nozzle brick, stud, the first screw-casing becomes as a whole.3, be contained in by mechanism rack on stud, leg withstands on ladle bottom, now, utilizes the second screw-casing rotation and mechanism rack to support the pulling force produced, nozzle brick, stud, the first screw-casing entirety is pulled out from pocket block, reach the object of nozzle brick quick change.
The good effect that the utility model produces: originally used water cooling, when pneumatic pick smashes the mouth of a river, it is 1h that ladle is changed the mouth of a river consuming time, after employing this spiral puller nozzle quick-change device, replacing operation can be carried out to the red heat mouth of a river in ten minutes, shorten the outlet replacing time greatly, improve the red heat turnover rate of ladle, good booster action is served to the cost efficiency of front and back operation.
The utility model is rational in infrastructure, easy to operate, pulls out fast under achieving the condition of high temperature by overall in steel base brick for nozzle brick, decrease cooling of originally fetching water, the operation of the broken nozzle brick of pneumatic pick, save the time changing nozzle brick, accelerate the heat turnover of ladle, reduce production cost.
Accompanying drawing explanation
Do further statement below in conjunction with accompanying drawing to the utility model, Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
