Description
Technical field
The utility model is related to fused cast refractories sand mo(u)ld, especially a kind of zirconia-corundum refractory brick with riser sleeve commonly pours casting sand
Mould.
Background technology
In glass furnace, main building materials are zirconia-corundum refractory bricks, and glass metal part is contacted in glass furnace
Fused cast refractories are mostly no shrinkage cavity casting, and flame space part is mostly common casting fused cast refractories, the requirement of no shrinkage cavity brick be it is fine and close,
Unit weight is 3.75 or more, the mechanical erosion of resistance to glass metal high temperature erosion and glass metal；Common casting is mainly that high temperature resistant corrodes, no
It is required that fine and close, unit weight is 3.45 or so.No shrinkage cavity configures that riser is big because there is a fine and close requirement, and the solution in riser can be with
Feeding is carried out to brick body, needs to cut away riser before processing.Common casting is required without densification, therefore configuration riser is small, and riser only needs
It destroys.The usually up big and down small round funnel-form of common casting pressing port setting, the about upper diameter 200mm of specification is extremely
Between 300mm.Lower diameter about 100mm is between 200mm.Cannot be a smooth perfect state when destroying riser after brick output,
Protrusion that not to be concave be exactly, brick face out-of-flatness when concave influence processing efficiency when raised, a raised part needs half an hour
Process time could eliminate.Have no alternative but that riser is needed to cut away, common casting pressing port is handling when cutting, steady due to smaller
Brick is all a cumbersome labour.Therefore, it is imperative to improve and innovate.
Utility model content
For the above situation, to overcome the defect of the prior art, the purpose of the utility model to be just to provide a kind of band riser
The zirconia-corundum refractory brick of circle is commonly cast sand mo(u)ld, can effectively solve the problems, such as fused cast refractories riser quick automatic separation of commonly casting.
The technical solution that the utility model solves is, a kind of zirconia-corundum refractory brick with riser sleeve is commonly cast sand mo(u)ld, packet
Brick body sand mold and riser sand mold are included, riser sleeve is provided between brick body sand mold and riser sand mold, is arranged on brick body sand mold upper head plate
There is circular casting gate up and down, the section of riser sleeve is rounded, and it is logical that riser sleeve is provided centrally with circle up and down
Hole, riser sand mold be provided centrally with up and down, present it is big under small truncated cone-shaped feed inlet, circular through hole is being located at casting gate just
Top, feed inlet are located at the surface of circular through hole, and casting gate, circular through hole and feed inlet are coaxial, and feed inlet lower end oral area is straight
Diameter is D2, a diameter of D3 of circular through hole, a diameter of D4 of casting gate, wherein D3-D2=10mm, D2=D4.
The height of the riser sleeve is 8-10mm, wall thickness 35mm.
The wall thickness of brick body sand mold and riser sand mold is 40mm.
The lower face of the riser sleeve is close to the upper surface of brick body sand mold, under the upper surface of riser sleeve and riser sand mold
It is close to end face.
The utility model structure novel is unique, and advantages of simple is easy to produce, easy to operate, at low cost, and the use of riser sleeve makes
The groove for generating a 5mm depth after casting in the coupling part of riser and brick body, slight crack, brick output are formed under the effect of expanding with heat and contract with cold
Light pumping afterwards, riser neat will fall off, and brick face is smooth, and common riser is not only made to exempt to cut, and can make the smooth light in riser face
It is sliding, remove riser cutting process from, saves plenty of time, artificial and power consumption, improve the exterior quality in common casting pressing port face, use
Convenient, effect is good, there is good social and economic benefit.
