Description
Technical field
The utility model is related to a kind of refractory material, more particularly to a kind of bending part connection magnesia carbon brick.
Background technology
Magnesia carbon brick is with 2800 DEG C of high-melting-point alkalescence oxides magnesium fusing point and the high-melting-point carbon for being difficult to be invaded by slag profit
Cellulosic material adds various non-oxidized substance additives as raw material.The composite fire material of not making charcoal being combined into carbonaceous bonding agent
Material.Magnesia carbon brick is mainly used in the positions such as the liner of converter, ac arc furnace, direct current electric arc furnace, the slag line of ladle.
Magnesia carbon brick is led as a kind of composite refractory, strong and carbon the height of slag corrosion resistance ability for efficiently utilizing magnesia
Hot and low expansion, compensate for the disadvantage of magnesia spalling resistance difference.Patent No. application number in the prior art：
The utility model patent of 201220237875.X《It is a kind of can multiple hot swap steelmaking converter protective casing for ventilating brick brick》Middle public affairs
Opened it is a kind of can multiple hot swap steelmaking converter protective casing for ventilating brick brick, belong to converter installation technical field, for converter
The air brick that top bottom blowing process matching is used is made steel, its technical scheme is：It is made up of upper set brick and brick of trapping, upper set
Brick is connected with brick of trapping, and the bottom of brick of trapping is connected with furnace bottom brick cup, the outer phase of the upper endoporus and core brick epimere for covering brick
Matching, endoporus and the periphery of core brick stage casing circular cone stage body of brick of trapping match, and fit clearance is 1~2mm；Above set brick is magnesium carbon
Brick, brick of trapping is corundum castable.The utility model uses two body combining structures, and upper set brick is direct working lining, and material is magnesium
Carbon brick, brick of trapping is indirect working lining, and material is corundum castable, and this structure and material have good elevated temperature strength and resist
Heat is shaken performance, improves the intensity of protective case brick, protective case brick is undergone the drilling and vibration of drilling machine, adapts to core brick
Multiple hot swap, saved cost, improve efficiency.
This kind of brick is relatively conventional brick body, but is asked in the presence of certain as the magnesia carbon brick of switching part in the prior art
Topic.Switching part interior conduit lower bottom part of the prior art is horizontally disposed, therefore occurs that part remains when conducting
Thing is piled up situation in this and is occurred.So going down for a long time can cause interior conduit caliber to narrow, while will also result in circulation material
Loss.
Utility model content：
The purpose of the utility model patent is exactly to make up the deficiencies in the prior art, there is provided magnesium carbon is used in a kind of bending part connection
Brick, improves the turn-on rate of interior conduit, while turn-on rate can also be adjusted according to actually used situation.
To reach the purpose, a kind of bending part connection magnesia carbon brick of the utility model, including body, set on the body
There are feeding mouth and discharging opening, feeding mouth and discharging opening are connected by the L-shaped passage in body, and the L-shaped passage bending part is provided with
One assembly annex, the assembled attachment surface is smooth slope.
Preferably, L-shaped passage includes vertical section and horizontal segment, and the assembled annex is by the on the wall of vertical section side
One assembling skewback, the second assembling skewback on horizontal segment, and installed in the first assembling skewback and the second assembling skewback
Between the 3rd assembling skewback.
Preferably, the height of the first assembling skewback is not higher than the 1/4 of vertical section side wall.
Preferably, the height of the second assembling skewback is not higher than the 1/8 of vertical section side wall.
Preferably, the 1/2 of of length no more than horizontal section length of the 3rd assembling skewback.Numerical Design above is comprehensive
The design that velocity of liquid assets and circulation are carried out is closed, line clogging will not have been caused while speed is improved.
Preferably, assembled attachment surface is provided with discontinuous ceramic layer.Such structure is reduced between annex and circulation material
Friction, while once have it is substantial amounts of circulation material attachment, it is also possible to the circulation material of accumulation is removed by breaking ceramic layer into pieces.
The utility model passes through such structure and is avoided that first in use due to becoming in switching part speed
Blocked caused by changing, while it also avoid causing the reduced radius that circulate due to being provided with annex.Cutting for switching part can be effectively improved
Residue rate inside face utilization rate and reduction.
Brief description of the drawings:
Fig. 1 is a kind of structural representation of bending part connection magnesia carbon brick of the utility model.
Specific embodiment:
As shown in figure 1, being a kind of this practical bending part connection magnesia carbon brick, body 1, the body 1 is provided with feeding mouth 2
With discharging opening 3, feeding mouth 2 and discharging opening 3 are connected by the L-shaped passage in body 1, and the L-shaped passage bending part is provided with one group
Assembled annex, the assembled attachment surface is smooth slope.
L-shaped passage includes vertical section and horizontal segment, and the assembled annex is by the first assembling on the wall of vertical section side
Skewback 4, on horizontal segment second assembling skewback 5, and installed in first assembling skewback 4 and second assembling skewback 5 it
Between the 3rd assembling skewback 6.
The height of the first assembling skewback 4 is not higher than the 1/4 of vertical section side wall.The height of the second assembling skewback 5
Not higher than the 1/8 of vertical section side wall.The 1/2 of of length no more than horizontal section length of the 3rd assembling skewback 6.
It should be noted that, although assembled annex is the structure that three pieces of assembling skewbacks are installed simultaneously in figure, but in reality
Can also be using the single first assembling assembling assembling skewback 4 and second of skewback 5 or first of skewback 4, second during use
Assemble skewback 5 is combined as assembled annex.Thus can be suitably used for various requirement.
Assembled attachment surface is provided with discontinuous ceramic layer.
The utility model is very easy to use, and assembled annex is arranged in the pipeline of bending part connection magnesia carbon brick
Use, the structure difference according to assembled annex improves the transmission speed of circulation material, while effectively having utilized the section of pipeline.Though
So look that pipeline section area reduces after assembled annex is provided with, but due to original design not science, top half
Space is in fact to waste, and its space can be made full use of on the contrary after being mounted with assembled annex, has reached good effect.
