Abstract
The utility model discloses a kind of quick change cold burden frame, comprise cold burden circle body (4), bead is provided with handle (3) at an upper portion thereof, and the bottom in described cold burden circle body (4), is provided with base membranes (1); Middle part in described cold burden circle body (4), is provided with middle part interlayer (2).Adopt technique scheme, quick change cold burden frame can be improved, improve molten steel in mold setting rate, shorten the continuous pouring process quick-replaceable tundish time; When quick change, quick change cold burden frame middle level adds interlayer and is putting into crystallizer, and middle level screw-thread steel is in 50mm place under crystallizer liquid steel level, accelerates at bottom and middle level molten steel solidification speed, thus reaches cold burden frame and be connected with the rapid solidification of Mold; And, put solidify cold burden time, cold burden can not slide down along liquid core, and thawing speed slows down, and avoids the generation of Inner Quality of Billet problem.
Description
Technical field
The utility model belongs to the technical field that metallurgical industry is produced, and relate to continuous casting manufacturing technique equipment, more particularly, the utility model relates to a kind of quick change cold burden frame.
Background technology
Continuous casting quick change needs to shorten the quick change time, increases quick change success rate, guarantees slab quality, enhance productivity.
At present, in continuous casting quick change process, after putting into cold burden frame, setting rate is slow, extends the quick change time; Put and solidify cold burden and easily make cold burden slide down along liquid core, thus affect Inner Quality of Billet and composition.
Utility model content
The utility model provides a kind of quick change cold burden frame, its objective is and improves molten steel in mold setting rate.
To achieve these goals, the technical scheme that the utility model is taked is:
Quick change cold burden frame of the present utility model, comprise cold burden circle body, bead is provided with handle at an upper portion thereof, and the bottom in described cold burden circle body, is provided with base membranes.
Middle part in described cold burden circle body, is provided with middle part interlayer.
Described base membranes arranges that three diameters are Φ 18mm, length is the screw-thread steel of 120mm.
Described middle part interlayer arranges that three diameters are Φ 18mm, length is the screw-thread steel of 180mm.
Under the duty of quick change, the screw-thread steel on described middle part interlayer is in 50mm place under crystallizer liquid steel level.
Described quick change cold burden frame is applied to the rectangular bloom of 370 × 480mm.
The utility model adopts technique scheme, can improve quick change cold burden frame, improves molten steel in mold setting rate, shortens the quick-replaceable tundish time; When molten steel cast terminates to prepare quick change, by in the middle part of framework and the soldered cold burden frame of base membranes put into crystallizer, middle level screw-thread steel is in 50mm place under crystallizer liquid steel level, accelerate in bottom and middle level molten steel solidification speed, thus reach cold burden frame and be connected with the rapid solidification of Mold; And, put solidify cold burden time, cold burden can not slide down along liquid core, and thawing speed slows down, and avoids the generation of Inner Quality of Billet problem.
Accompanying drawing explanation
Mark in content shown in accompanying drawing and figure is as follows:
Fig. 1 is structural representation of the present utility model;
Be labeled as in figure:
1, base membranes, 2, middle part interlayer, 3, handle, 4, cold burden circle body.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
Structure of the present utility model expressed by Fig. 1, is a kind of quick change cold burden frame, is applied to the rectangular bloom of 370 × 480mm.
In order to solve prior art Problems existing and overcome its defect, realize the goal of the invention improving molten steel in mold setting rate, the technical scheme that the utility model is taked is:
As shown in Figure 1: quick change cold burden frame of the present utility model, comprise cold burden circle body 4, bead is provided with handle 3 at an upper portion thereof, and the bottom in described cold burden circle body 4, is provided with base membranes 1.
Middle part in described cold burden circle body 4, is provided with middle part interlayer 2.
The utility model, by above-mentioned a kind of simple mechanism, can improve quick change cold burden frame, improves molten steel in mold setting rate, shortens the continuous pouring process quick-replaceable tundish time.
Described base membranes 1 arranges that three diameters are Φ 18mm, length is the screw-thread steel of 120mm.
Described middle part interlayer 2 arranges that three diameters are Φ 18mm, length is the screw-thread steel of 180mm.
Technological improvement of the present utility model is that the bottom of quick change cold burden frame and middle level are added interlayer.The long 120mm of screw-thread steel 3 of Φ 18mm is added at bottom; Middle level adds the long 180mm of screw-thread steel 3 of Φ 18.
Under the duty of quick change, the screw-thread steel on described middle part interlayer 2 is in 50mm place under crystallizer liquid steel level.
Device of the present utility model is when quick change, quick change cold burden frame middle level adds interlayer and is putting into crystallizer, middle level screw-thread steel is in 50mm place under crystallizer liquid steel level, accelerates at bottom and middle level molten steel solidification speed, thus reaches cold burden frame and be connected with the rapid solidification of Mold.And, put solidify cold burden time, cold burden can not slide down along liquid core, and thawing speed slows down.Avoid affecting Inner Quality of Billet problem.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
