Abstract

The utility model discloses a permanent layer brick of ladle heat preservation, including the brick body of arc structure, be provided with the sand grip at the concatenation end one side middle part of the brick body along width direction, set up the card solid groove of splicing with the sand grip adaptation at its opposite side middle part along width direction. The utility model has the advantages of simple structure and simple and convenient processing and manufacturing. The convex strips and the clamping grooves which are matched with each other are arranged on the two splicing sides of the brick bodies, so that the two adjacent brick bodies can be spliced together tightly, the connection of the brick bodies is firmer, the integrity and the continuity of the permanent layer of the steel ladle are ensured, the occurrence of the falling phenomenon of the brick bodies is reduced, more than ten package services can be continuously used, and the service life of the permanent layer is greatly prolonged.

Description

Ladle heat-insulating permanent layer brick
Technical Field
The utility model relates to a resistant firebrick especially relates to a can effective anti-drop's permanent layer brick of ladle heat preservation.
Background
The ladle is a container for holding and transporting molten steel, heat is dissipated in the molten steel transferring process, molten steel cooling is caused, secondary refining and continuous casting are not facilitated, and therefore a heat preservation permanent layer is built on the inner wall of the outer shell of the conventional ladle in a clinging mode. The heat-insulating permanent layer is generally directly built by adopting a shaped product (heat-insulating permanent layer brick), or the paved heat-insulating permanent layer brick is cast and molded by using an unshaped casting material; the steel ladle manufactured by the two methods is easy to fall off of individual heat-preservation permanent layer brick bodies during the use process, particularly after a plurality of ladles are in service, and the brick bodies fall off firstly because the hoisting and the ladle-to-ladle of the steel ladle are a dynamic process and have uninterrupted repetition of vibration, displacement and inversion; secondly, because the ladle is used for cold repair and hot repair, the volume of the ladle shell can be changed due to expansion with heat and contraction with cold, and the bricks on the permanent heat-insulating layer are easy to loosen.
Disclosure of Invention
The utility model aims to provide a simple structure, the permanent layer brick of ladle heat preservation that manufacturing is simple and convenient.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
ladle heat preservation permanent layer brick, including the brick body of arc structure the concatenation end one side middle part of the brick body is provided with the sand grip along width direction, seted up at its opposite side middle part along width direction with the card solid groove of sand grip adaptation concatenation.
The brick body is 200mm in length, 90mm in width and 70mm in thickness; the cross section of the convex strip is of a semicircular structure with the diameter of 20mm, and the cross section of the clamping groove is of a semicircular structure with the diameter of 23 mm.
The utility model has the advantages of simple structure and simple and convenient processing and manufacturing. The convex strips and the clamping grooves which are matched with each other are arranged on the two splicing sides of the brick bodies, so that the two adjacent brick bodies can be spliced together tightly, the connection of the brick bodies is firmer, the integrity and the continuity of the permanent layer of the steel ladle are ensured, the occurrence of the falling phenomenon of the brick bodies is reduced, more than ten package services can be continuously used, and the service life of the permanent layer is greatly prolonged.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a left side view of fig. 1.
Fig. 3 is a schematic diagram of the splicing structure of the present invention.
Detailed Description
As shown in fig. 1 and 2, the ladle heat-insulating permanent layer brick of the utility model comprises a brick body 1 with an arc structure, wherein the brick body 1 has a length of 200mm, a width of 90mm and a thickness of 70 mm; of course, during actual production, the size of the brick body 1 can be adjusted according to the sizes of the inner cavities of different ladles. The left side and the right side of each brick body 1 are splicing sides, and the bricks are continuously spliced to form an annular structure and are fixedly attached to the inner wall of the steel ladle; be provided with sand grip 2 along width direction in the right side concatenation terminal surface middle part of the brick body 1, the section of sand grip 2 is the semi-circular structure of diameter 20mm, offers the card solid groove 3 of splicing with sand grip 2 adaptation along width direction in the left side concatenation terminal surface middle part of the brick body 1, and the section of card solid groove 3 is the semi-circular structure of diameter 23mm, slightly is greater than sand grip 2 to make sand grip 2 can easily clamp in card solid inslot 3.
When the ladle heat-preservation permanent layer is built, as shown in fig. 3, the raised lines 2 on the right end surface of one brick body 1 are in adaptive clamping connection with the clamping grooves 3 on the left end surface of the other brick body 1, so that the bricks are arranged side by side for building to form a heat-preservation permanent layer with an annular structure, and then the bricks are stacked layer by layer according to the method for building until the brick bodies 1 completely cover the inner wall of the ladle to form the heat-preservation permanent layer of the ladle.

Claims (1)

1.
