Abstract
The utility model discloses a symmetrical multi-stream pouring box integral ladle cover, which belongs to the field of continuous casting equipment and is used for solving the problems of easiness in burning out and short service life existing in the conventional pouring box ladle cover. The symmetrical multi-stream pouring box integral ladle cover consists of a criss-cross integral steel skeleton and fire-retardant castables; the fire-retardant castables are combined with the steel skeleton into a flat cuboid structure through anchoring pieces welded on the steel skeleton; the periphery of the cuboid is coated with a steel outer frame; the size of the cuboid adapts to that of the pouring box; and the cuboid which is provided with stopper holes and baking holes is bilateral. Due to the adoption of the integral steel skeleton ladle cover, the strength is increased; a ladle cover jointing part is omitted, so that the integral airtightness is high, and high-temperature gas is prevented from leaking out easily; the fire-retardant castables are arranged above and below the ladle cover, so that the situation of easiness in burning out of the steel plate surface of an original ladle cover is avoided; and after the edge of the ladle cover which is used for a certain period of time is deformed and upwarps, the ladle cover can be overturned for continuous use since the ladle cover is designed with a bilateral structure, so that the service life of the ladle cover is prolonged.
Description
Technical field
The utility model relates to the continuous casting tundish, relates in particular to the whole clad of a kind of symmetrical multithread tundish.
Background technology
The tundish clad mainly is when tundish toasts, to play insulation, heat insulation effect, and its result of use quality is directly connected to the cured effect of tundish, and then influences conticaster and open and water success rate.Wuhan Iron and Steel Plant steel mill 5 stream billet caster tundish clads are made up of three splicings; Clad upper surface and be steel plate all around; The centre is a castable refractory, and the directly roasting joint portion of processing three clads of about 1200 ℃ high-temperature gas in the tundish makes very easily scaling loss of clad steel construction during baking; Castable refractory comes off comparatively fast, has had a strong impact on clad service life.
The utility model content
The purpose of the utility model is to overcome the prior art defective, provides a kind of symmetrical multithread tundish whole clad.
The technical scheme of the utility model is achieved in that the whole clad of symmetrical multithread tundish; It is that it is made up of crisscross whole steel skeleton and castable refractory, and castable refractory is combined into a flat rectangular structure through anchoring piece and the steel skeleton that is welded on the steel skeleton; Be surrounded by the steel housing around the cuboid; Cuboid size and tundish size adapt, and have stopper hole and baking hole on the cuboid, have the cuboid left-right symmetric in stopper hole and baking hole.
Preferably, whole steel skeleton is welded by steel pipe, and it is central to be positioned at flat cuboid thickness.
Preferably, be connected with refrigerating gas in the steel pipe.
The utility model adopts whole steel skeleton clad, has increased intensity; Owing to cancelled the clad joint portion, overall tightness is strong, and high-temperature gas is difficult for scurrying out; The clad top and bottom all are castable refractories, have avoided original clad surface of steel plate to be prone to the situation of scaling loss; Upwarp as if the clad edgewise distortion after using a period of time, because clad is designed to the left-right symmetric structure, but the use of left and right sides turn-over continued, these have all improved the service life of clad.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model;
Among the figure: the 1-steel skeleton, 2-stopper hole, 3-toasts the hole, 4-steel housing, 5-castable refractory.
The specific embodiment
Further describe below in conjunction with accompanying drawing:
As shown in Figure 1; The whole clad of symmetry multithread tundish is made up of with castable refractory 5 the whole steel skeleton 1 of crisscross groined type, and castable refractory 5 is combined into a flat rectangular structure through anchoring piece and the steel skeleton 1 that is welded on the steel skeleton 1; Be surrounded by steel housing 4 around the cuboid; Cuboid size and tundish size adapt, and have stopper hole 2 and baking hole 3 on the cuboid, have the cuboid left-right symmetric in stopper hole 2 and baking hole 3.
During manufacturing; Be welded into " well " Zee bar steel Z skeleton 1 in the middle part of clad thickness with the seamless steel pipe about diameter 60mm; The weld anchor firmware is watered castable refractory 5 then to increase clad intensity on the steel skeleton 1, wraps steel housing 4 around the cuboid; And open symmetrical stopper hole 2 and baking hole 3 by the job requirement of symmetrical multithread tundish, can use after the drying.Can in seamless steel pipe, lead to compressed air in case of necessity or inert gas cools off.
When clad uses certain number of times, when upwarping about 50mm appearred in clad two, clad left and right sides turn-over is used; The characteristics that 5 temperature distortions upwarp by castable refractory; Make clad be tending towards smooth,, move in circles as upwarping then turn-over once more once more; Can suitably repair the damaged castable refractory 5 in clad bottom surface simultaneously, prolong the clad life-span.
