Abstract
The invention discloses an embedded type separated porous pocket brick for a steel ladle. The embedded type separated porous pocket brick comprises an upper porous pocket brick body and a lower porous pocket brick body. The upper porous pocket brick body and the lower porous pocket brick body are connected together in a primary-secondary opening manner. A convex round table is arranged at the bottom of the lower porous pocket brick body and is a round-table-shaped secondary opening. A primary opening structure matched with the lower porous pocket brick body is arranged on a steel ladle bottom housing. The convex round table of the lower porous pocket brick body is fixed in the steel ladle bottom housing when the embedded type separated porous pocket brick is mounted. As the lower porous pocket brick body is fixed in the steel ladle bottom housing, the phenomena of dislocation and slippage, which may occur when the porous pocket brick is mounted and used, can be effectively prevented. The porous pocket brick has good stability and safety. The lower porous pocket brick body can be repeatedly used, and the use amount and the cost of a fire-resistant material can be effectively reduced.
Description
Technical field
The present invention relates to the ventilative brick cup at the bottom of the refining ladle bag in the STEELMAKING PRODUCTION, particularly relate to the ventilative brick cup of a kind of embedded ladle.
Background technology
Present steel mill carries out stove with refining ladle and smelts outward, and most refinings need be carried out the BOTTOM ARGON BLOWING stirring, reaches the effect of homogenizing molten steel, better slag making.This process for making, compact steps, ventilative core must meet the requirements of Air permenbility.In case, must stop to wrap cold repair and handle because the serious or ventilative core of brick cup erosion corrodes seriously.Ventilative brick cup of dress and the ventilative brick cup of outer dress in ventilative brick cup is divided into, the ventilative brick cup of interior dress is that ventilative core of BOTTOM ARGON BLOWING and ventilative brick cup are as a whole, ventilative core can not be changed, and must change air brick in cold bag back; The ventilative brick cup of outer dress is that the ventilative core of BOTTOM ARGON BLOWING separates with ventilative brick cup, and ventilative core can not stop bag and change.Therefore the ventilative brick cup of outer dress iron and steel enterprise is at home popularized gradually.
The ventilative brick cup of outer dress is divided into monoblock type and split type again.The ventilative brick cup of monoblock type is widely used its good integrity, simple installation at present.Fracture in use takes place and makes the bag end that the danger of bleed-out arranged in whole ventilative brick cup easily.Whole ventilative brick cup must remove unreacted residual lining when changing, and has so wasted refractory material.The patent No. is a kind of split type ventilative brick cup of 200920249893.8 introductions; Be made up of last brick cup and following brick cup, following brick cup top has increased step, and brick cup brick body cooperates installation through mother-son mouth up and down; Avoid the formation in straight-through slit, can prevent the generation of bleed-out phenomenon.But, following brick cup install with use in dislocation and slippage take place easily, thereby make the difficult installation of ventilative core, in the time of seriously even need do over again and reinstall, thereby limited promoting the use of of split type brick cup.
Summary of the invention:
The object of the invention is intended to overcome above-mentioned shortcoming, provides a kind of embedded split ladle that can stop ventilative brick cup that dislocation and slippage take place in installation and use ventilative brick cup.
For realizing above-mentioned purpose, the present invention adopts following solution:
A kind of embedded split ladle brick cup of breathing freely; Comprise ventilative brick cup brick body and the ventilative brick cup brick body down gone up; Both connect with the mother-son mouth form; It is characterized in that: ventilative brick cup brick body bottom down is provided with the protrusion round platform, is the circular platform type rim of the mouth, and the ladle drain pan is provided with and the ventilative supporting female mouth structure of brick cup brick body down.The protrusion round platform of brick cup of will breathing freely down during installation embeds in the ladle drain pan fixing.
The above-mentioned embedded split ladle brick cup of breathing freely is characterized in that: said ventilative to go up brick cup brick body top be cylinder or cubic cylinder, and the bottom is the circular platform type rim of the mouth.
The above-mentioned embedded split ladle brick cup of breathing freely is characterized in that: said ventilative brick cup brick body down is cubic cylinder, and the top is provided with and supporting female mouthful of last brick cup brick body.
Above-mentioned ventilative upper and lower brick cup brick body is one-time cast-forming, and material can be identical, also can be different.
Compared with prior art, the invention has the advantages that:
1, stability is high.Breathe freely and fix in the brick cup embedding ladle drain pan down, can prevent effectively that ventilative brick cup from taking place to misplace and sliding phenomenon in installation and use, more changing jobs of the ventilative core of assurance is not interrupted.
2, safe.Ventilative brick cup adopts split type mother-son mouth to connect, and can guarantee effectively suiting of the ventilative upper and lower split of brick cup, has avoided forming straight-through slit again, effectively prevents bleed-out; Ventilative brick cup position is fixing simultaneously, can strengthen the protection to ventilative core.
3, cost effectively reduces.The erosion of ventilative brick cup can not arrive ventilative brick cup position down usually; Upper and lower brick body mother-son mouth structure of the present invention in addition can guarantee brick cup position and stability of structure with the ventilative damascene structures of brick cup down; Truly realize the ventilative use repeatedly of brick cup down, effectively reduce the consumption and the cost of refractory material.

Among the figure: 1, ventilative brick cup brick body 2, ventilative brick cup brick body 3, the ladle drain pan down gone up
The specific embodiment:
See figures.1.and.2; A kind of embedded split ladle brick cup of breathing freely is made up of with ventilative brick cup brick body 2 down the ventilative brick cup brick body 1 of going up, and wherein going up brick cup 1 is cylinder; Ventilative brick cup 2 down is cubic cylinder, and the ventilative brick cup 1 of going up cooperates with the mother-son mouth form with ventilative brick cup 2 down.During installation, the brick cup 2 bottoms protrusions round platform of will breathing freely down earlier is embedded in the ladle drain pan 3, will breathe freely to go up brick cup 1 and be placed in the ventilative brick cup 2 down again, and inspection is used the closely knit filling of pours on every side to behind the good mother-son mouth.In the use, after ventilative last brick cup 1 reaches the limit safe in utilization, change and reinstall the ventilative brick cup 1 of going up and get final product.
With reference to Fig. 1 and Fig. 3; A kind of embedded split ladle brick cup of breathing freely is made up of with ventilative brick cup brick body 2 down the ventilative brick cup brick body 1 of going up, and wherein going up brick cup 1 is cubic cylinder; Ventilative brick cup 2 down is cubic cylinder, and the ventilative brick cup 1 of going up cooperates with the mother-son mouth form with ventilative brick cup 2 down.During installation, the brick cup 2 bottoms protrusions round platform of will breathing freely down earlier is embedded in the ladle drain pan 3, will breathe freely to go up brick cup 1 and be placed in the ventilative brick cup 2 down again, and inspection is used the closely knit filling of pours on every side to behind the good mother-son mouth.In the use, after ventilative last brick cup 1 reaches the limit safe in utilization, change and reinstall the ventilative brick cup 1 of going up and get final product.
