Abstract
The utility model belongs to the technical field of fire resistant material appliances, particularly relates to a novel steel ladle perpetual layer high-alumina brick, and discloses the novel steel ladle perpetual layer high-alumina brick. The novel steel ladle perpetual layer high-alumina brick is characterized by comprising a ladle bottom perpetual layer, a brick layer constructed on the ladle bottom perpetual layer comprises a plurality of arc bricks, one end of each arc brick is an arc protrusion, the other end of each arc brick is an arc groove, the protrusions and the grooves can be combined in an inserted mode, the arc bricks constitute the brick layer due to the fact that the protrusions and the grooves are combined in the inserted mode, and a steel board is welded to the brick layer. The novel steel ladle perpetual layer high-alumina brick is long in service life and improves the turnover rate of a steel ladle, one-time service life is more than three times that of traditional castable, and resistant material consumption is reduced.
Description
Technical field
The utility model belongs to refractory material apparatus technical field, relates in particular to a kind of novel permanent ladle layer high-alumina brick.
Background technology
Ladle is used for steel mill, Foundry Works accepts molten steel, carries out pouring practice before open hearth, electric furnace or converter.And the general employing of the permanent layer of ladle at present is all that the castable cast forms or adopt straight shaped brick to build by laying bricks or stones.This type of permanent ladle layer has following defective: the one,, adopting is all that the castable cast forms, and intensity is relatively poor, and service time is shorter; The 2nd,, when having adopted straight shaped brick to build by laying bricks or stones, have three angle seams between straight shaped brick and occur in straight shaped brick arc transition, thereby make permanent layer the gap occur, affect its use; The 3rd,, owing to being straight shaped brick, so need cutting at any time to adjust straight shaped brick when building by laying bricks or stones, adjusting for size and the angle of straight shaped brick, thereby make brick-building art complicated, operating efficiency reduces.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of novel permanent ladle layer high-alumina brick is provided, and its technical scheme is as follows:
A kind of novel permanent ladle layer high-alumina brick, it is characterized in that, described novel permanent ladle layer high-alumina brick comprises end permanent layer, built the brick layer at the bottom of described bag on permanent layer by laying bricks or stones, described brick layer comprises some camber bricks, and an end of described camber brick is the projection of arcuation, the other end of described camber brick is the groove of arcuation, described projection and groove can plug combination, and described brick layer is combined by the grafting of some camber bricks through projection and groove, is welded with steel plate on described brick layer.
Optimal way is, and is bonding by high-alumina refractory mud between permanent layer and brick layer at the bottom of described bag.
Optimal way is to be cast with castable refractory between described camber brick.
The novel permanent ladle layer high-alumina brick that the utility model provides when in use, first wraps end permanent layer to specific thickness with the knotting of permanent layer pouring materialfor steel ladle, then uses camber brick brick is put successively, and the camber brick combines through the grafting of projection and groove.Use high-alumina refractory mud bonding full between bag end permanent layer and camber brick, build camber brick on the beginning screw when the camber of bottom is brick after complete, use Plate Welding to reinforce until build the steel ladle opening place by laying bricks or stones, seam is with bag mouthful castable cast more than bag mouthful pressure ring.
Bonding by high-alumina refractory mud between permanent layer and brick layer at the bottom of bag described in the utility model.Make the permanent layer of guaranteeing the minimum be connected connection with the brick layer more firm, strengthened its working strength.
Be cast with castable refractory between camber brick described in the utility model.Pour into a mould castable refractory between the camber brick, can so that the connection between the camber brick is more firm, also make its fire resistance more outstanding simultaneously.
The utility model has adopted the camber brick to substitute straight shaped brick, makes in arc transition, and the camber brick can play the transition of nature, need not the camber brick is cut adjustment, only need to mutually be plugged in together the camber brick just passable.The camber brick makes when building by laying bricks or stones can not produce three angle seams, and the technique of building by laying bricks or stones that is is also simultaneously oversimplified, and more is conducive to constructing operation.
The utility model is simple in structure, and easy construction improves the labor effect, and when building by laying bricks or stones, the permanent layer brick once spirals up, and need not cut the adjustment brick midway.Safety coefficient is high, the shortcoming of three angle seams when overcoming straight shaped brick and building by laying bricks or stones, and permanent layer is seamless.Simultaneously because the advantage of material and manufacture view, even refractory brick bleed-out occurs, leak slag, wears the molten steel such as bag and touch on permanent layer, the molten steel permanent layer is leaked on the ladle shell.High life improves the ladle turnover rate.Be more than 3 times of traditional castable disposable service life, saves refractory consumption.And after the permanent layer brick masonry is completed, can directly build refractory brick by laying bricks or stones, during baking, the baking bag time also can shorten, and can not cause curing time longer, takies the bad phenomenon of ladle shell.

The specific embodiment
Illustrate embodiment below in conjunction with Fig. 1 and Fig. 2:
A kind of novel permanent ladle layer high-alumina brick, it is characterized in that, described novel permanent ladle layer high-alumina brick comprises end permanent layer 1, built brick layer 2 at the bottom of described bag on permanent layer 1 by laying bricks or stones, described brick layer 2 comprises some camber bricks 3, one end of described camber brick 3 is the projection 4 of arcuation, the other end of described camber brick 3 is the groove 5 of arcuation, described protruding 4 and groove 5 can plug combination, described brick layer 2 is combined by the grafting of some camber bricks 3 through projection 4 and groove 5, is welded with steel plate 6 on described brick layer 2.
Optimal way is, and is bonding by high-alumina refractory mud between permanent layer and brick layer at the bottom of described bag.
Optimal way is to be cast with castable refractory between described camber brick.
The novel permanent ladle layer high-alumina brick that the utility model provides when in use, first wraps end permanent layer to specific thickness with the knotting of permanent layer pouring materialfor steel ladle, then uses camber brick brick is put successively, and the camber brick combines through the grafting of projection and groove.Use high-alumina refractory mud bonding full between bag end permanent layer and camber brick, build camber brick on the beginning screw when the camber of bottom is brick after complete, use Plate Welding to reinforce until build the steel ladle opening place by laying bricks or stones, seam is with bag mouthful castable cast more than bag mouthful pressure ring.
