Abstract
Description
Technical Field
[0001] The utility model relates to the field of refractory bricks, and more specifically to a downspout brick. Background Art
[0002] In the steel smelting process, the ladle is a vital container, and the ladle drain brick is one of the key components in the ladle system.
[0003] The downspout brick of the ladle is generally installed on the refractory plate of the ladle slide mechanism. The refractory plate of the ladle slide mechanism moves to drive the flow channel of the downspout brick to overlap or misalign with the through hole of the ladle, so as to achieve the effect of opening and closing the through hole of the ladle. In order to improve the sealing of the connection between the downspout brick and the refractory plate of the ladle slide mechanism after installation, it is generally necessary to use a jig to first cover the top of the downspout brick to form a mold cavity, and then apply sealing mud inside the mold cavity, and then remove the jig, and then connect the downspout brick to the metal shell and then dock it with the hole on the refractory plate of the ladle slide mechanism. Such downspout bricks are not only not convenient for applying sealing mud, but also because the top of the downspout brick is relatively flat, it is not conducive to the sealing of the connection after docking with the hole on the refractory plate, which increases the risk of molten steel leakage. Therefore, we propose a downspout brick to solve the above-mentioned problems. Utility Model Content
[0004] 1. Technical issues to be solved
[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a drain brick, which is provided with a closing edge and a limiting edge on the top of the drain brick body, so that a coating area can be formed, and the sealing mud can be directly coated inside the coating area without the aid of a jig, thereby improving the convenience of coating the sealing mud, and because the closing edge is provided on the top of the drain brick body, the closing edge can be directly inserted into the hole on the refractory board when it is docked with the hole on the refractory board, thereby improving the stability and sealing of the docking structure and reducing the risk of molten steel leakage at the connection.
[0006] 2. Technical solution
[0007] To solve the above problems, the utility model adopts the following technical solutions.
[0008] A drain brick comprises a drain brick body, a metal shell is sleeved on the outer side of the drain brick body, a flow channel is opened inside the drain brick body, a closing edge is fixedly connected to the top of the flow channel, and a limiting edge is also fixedly connected to the top of the drain brick body, a plurality of overflow openings are equidistantly opened on the limiting edge, a smearing area is formed between the closing edge and the limiting edge, and sealing mud is smeared inside the smearing area.
[0009] Furthermore, the downspout brick body is a tubular structure formed by integral sintering, a basalt wire mesh layer is arranged inside the downspout brick body, and the surface of the downspout brick body is smooth and free of burrs.
[0010] Furthermore, the height of the closing edge is greater than the height of the limiting edge, and the top of the sealing mud cross section is an inclined structure.
[0011] Furthermore, the diameter of the outer wall of the limiting edge is smaller than the diameter of the outer wall of the top of the downspout brick body, and a mud overflow area is formed between the outer wall of the limiting edge and the outer wall of the top of the downspout brick body.
[0012] Furthermore, the bottom of the outer wall of the downspout brick body is in a semi-elliptical structure, and the inner wall structure of the metal shell is compatible with the outer shape structure of the downspout brick body.
[0013] 3. Beneficial effects
[0014] Compared with the prior art, the advantages of the present invention are:

In addition, since a closing edge is provided on the top of the downspout brick body, the closing edge can be directly inserted into the hole on the refractory board when it is docked with the hole on the refractory board, thereby improving the stability and sealing of the docking structure and reducing the risk of steel liquid leakage at the connection.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.
[0024] Embodiment 1:
[0025] See also Figure 1-Figure 4 A drain brick comprises a drain brick body 1, a metal shell 8 is sleeved on the outer side of the drain brick body 1, a flow channel 2 is opened inside the drain brick body 1, a closing edge 3 is fixedly connected to the top of the flow channel 2, and a limiting edge 4 is also fixedly connected to the top of the drain brick body 1, a plurality of overflow openings 5 are equidistantly opened on the limiting edge 4, a coating area 6 is formed between the closing edge 3 and the limiting edge 4, and a sealing mud 7 is coated inside the coating area 6;
[0026] The height of the closing edge 3 is greater than that of the limiting edge 4 , the top of the cross section of the sealing mud 7 is an inclined structure, the outer wall diameter of the limiting edge 4 is smaller than the outer wall diameter of the top of the drain brick body 1 , and a mud overflow area is formed between the outer wall of the limiting edge 4 and the outer wall of the top of the drain brick body 1 .
[0027] The use principle of this kind of drain brick is:
[0028] First, apply the sealing mud 7 to the inside of the coating area 6 on the top of the drain brick body 1, and grind the sealing mud 7 to make it smooth, then put the metal shell 8 on the outside of the drain brick body 1. At this time, the drain brick body 1 together with the metal shell 8 can be installed into the refractory board side of the ladle slide mechanism, and the closing edge 3 on the top of the drain brick body 1 is inserted into the hole of the refractory board, and the top of the drain brick body 1 and the hole connection are bonded by the sealing mud 7 to prevent the formation of gaps and the leakage of molten steel in the later stage. During the bonding process, it is necessary to squeeze the drain brick body 1 with force to make the top of the drain brick body 1 better in contact with the hole. At this time, the sealing mud 7 is also subjected to the extrusion force, and the excess sealing mud 7 will overflow, so that it can be smoothly discharged outward through the overflow opening 5.
