Abstract
The utility model discloses a purpose be exactly compensate prior art not enough, provide three -section pipe chute combination formula magnesium carbon brick, adopt a full brick to realize that three block groups close the stack effect of brick, reduced the process of equipment, the whole maintenance of being convenient for. For reaching the mesh, the utility model discloses three -section pipe chute combination formula magnesium carbon brick, including the brick body that has the through -hole, the through -hole includes that the cross -section is erecting long trapezoidal first combination portion, cross -section and is short trapezoidal second combination portion and the third combination portion of cross -section for the rectangle, the cross -section bottom width and the cross -section top width of second combination portion of first combination portion are unanimous, and the cross -section bottom width and the cross -section top width of third combination portion of second combination portion are unanimous the utility model discloses a such structure has good high temperature resistance ability, the especially incorruptibility under the high temperature and improves, and life increases, while anti sediment ability reinforce, and thermal shock resistance is good, and high temperature creep hangs down, and the system is more stable in the whole production process.
Description
Technical field
This utility model is related to a kind of refractory material, more particularly, to three sections inclined tube combination type magnesia carbon bricks.
Background technology
Magnesia carbon brick is with 2800 DEG C of high-melting-point alkalescence oxides magnesium fusing point and to be difficult to be invaded the high-melting-point carbon of profit by slag
Cellulosic material, as raw material, adds various non-oxidized substance additives.The composite fire material of not making charcoal being combined into carbonaceous bonding agent
Material.Magnesia carbon brick is mainly used in the liner of converter, ac arc furnace, direct current electric arc furnace, the position such as 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 efficiently utilizing magnesia
Hot and low expansion, compensate for the disadvantage of magnesia spalling resistance difference.Prior art Patent number is application number：
201220237875.X utility model patent《A kind of can multiple hot swap steelmaking converter protective casing for ventilating brick brick》Middle public affairs
Opened a kind of can multiple hot swap steelmaking converter protective casing for ventilating brick brick, belong to converter installation technical field, for converter
Make steel the air brick that top bottom blowing process matching uses, 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 covering brick and core brick epimere
Coupling, the endoporus of brick of trapping is matched with the periphery of core brick stage casing circular cone stage body, and fit clearance is 1～2mm；Above set brick is magnesium carbon
Brick, brick of trapping is corundum castable.This utility model adopts two body combinative structurees, and upper set brick is on-line operation layer, 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, enables protective case brick to stand drilling and the vibration of boring machine, adapt to core brick
Multiple hot swap, saved cost, improve efficiency.
But groove structure of the prior art is single it is difficult to competent complex function is it is therefore desirable to one kind is passed through
Through-hole structure brings the magnesia carbon brick of good result.
Utility model content：
The purpose of this utility model patent is exactly to make up the deficiencies in the prior art, there is provided three sections of inclined tube combination type magnesium carbon
Brick, realizes the Overlay of three pieces of modular tiles using a full brick, decreases the operation of assembling, is easy to overall maintenance.
For reaching described purpose, three sections of inclined tube combination type magnesia carbon bricks of this utility model, including the brick body with through hole, described
Through hole include section be the first trapezoidal combination section of perpendicular length, section be the of short the second trapezoidal combination section and rectangular cross-section
Three combination sections, the section-bottom width of described first combination section and the second combination section section-top width are consistent, the second combination section
Section-bottom width and the 3rd combination section section-top width consistent.
Preferably, the angle of inclination of the side wall of the first combination section is 85 80 degree.Such angle is not affecting conduction amount
Under the premise of guarantee that the material in through hole can clog-free pass through.
Preferably, the height of the second combination section is the 1/50 of the first combination section height, described second combination section section-top
Length difference with bottom is the twice of the second combination section height.Such structure makes an internal diameter enlarged portion in through hole,
Material here is avoided to block.Simultaneously in order to ensure the intensity of overall brick, this position can not be long.
Preferably, the height of described 3rd combination section is the 1/4 of the first combination section.This part is logical similar to normal brick body
Hole is it is ensured that the logistics in exit is passed through gently.
Preferably, brick body bottom is additionally provided with connection opening portion, described connection opening portion height and the second combination section
Highly consistent.Connection opening portion is used for and other brick body are connected with each other.
This utility model, by such structure, has good resistance to elevated temperatures, and the especially durability under high temperature carries
Height, service life increases, and anti-slag ability is strong simultaneously, good thermal shock, and high-temerature creep is low, and in whole production process, system is more steady
Fixed.
Brief description:
Fig. 1 is the structural representation of three sections of inclined tube combination type magnesia carbon bricks of this utility model.
Specific embodiment:
As shown in figure 1, three sections of inclined tube combination type magnesia carbon bricks, including the brick body 1 with through hole, described through hole includes section and is
The first trapezoidal combination section 2 of perpendicular length, section are the 3rd combination section 4 of short the second trapezoidal combination section 3 and rectangular cross-section, institute
Section-bottom width and the second combination section 3 section-top width of stating the first combination section 2 are consistent, the section bottom of the second combination section 3
Portion's width and the 3rd combination section 4 section-top width are consistent.The angle of inclination of the side wall of the first combination section 2 is 85 80 degree.Second
The height of combination section 3 is the 1/50 of the first combination section 2 height, and the length difference of described second combination section 3 section-top and bottom is
The twice of the second combination section 3 height.The height of described 3rd combination section 4 is the 1/4 of the first combination section 2.Brick body 1 bottom is also
Be provided with connection opening portion 5, described connection opening portion 5 height and the second combination section 3 highly consistent.
This utility model is very easy to use, the same with prior art brick body install and use, rely primarily on the knot in through hole
Structure changes to realize anti-slag ability by force, good thermal shock, the low technique effect of high-temerature creep.
