Abstract

The utility model provides a core mould in a zircon corundum fused brick mould with through holes, which effectively solves the problem of cracks in zircon corundum fused brick production. The technical scheme includes that the core mould comprises at least two core mould bodies in the axial direction, a 1-5mm gap is reserved between each two core mould bodies, and combustible materials are filled in the gaps. The core mould is simple in structure, easy in manufacture and fine in effect, zircon corundum fused bricks manufactured by the core mould have no crack and are fine in quality and high in yield, and the production costs of the zircon corundum fused bricks and the core mould are reduced effectively.

Description

Core in the band through hole fused alumina zirconia fused cast refractories mould

One, technical field

The utility model relates to a kind of with the core in the through hole fused alumina zirconia fused cast refractories mould.

Two, background technology

As everyone knows, Corhart Zac-block is the main furnace building material of current glass industry kiln, and it has high temperature resistant, erosion-resistant characteristics.Along with the glass industry kiln develops to maximization, all risk insurance warm type, Corhart Zac-block is had higher requirement.In decades, the production of China's Corhart Zac-block has very big development, and the annual production in the whole nation improves year by year, has satisfied the needs of domestic market basically.But compare with external like product, still having bigger gap qualitatively.

When producing Corhart Zac-block, the liquid that fusing is good pours in ready made sand mo(u)ld or other models.People generally believe that pattern quality and quality of item have very big relation.Be to guarantee quality of item, the quality of AZS bricks die just requires sand mold to have air permeability and good, impact strength, thermomechanical property and size and even curface accurately.Sand mold generally adds bond waterglass with silica sand and makes.Requirement to silica sand is SiO ₂Content is greater than 08, if SiO ₂Content is on the low side, impurity is many, then can influence the hear resistance of sand mold.The proportion of waterglass is 1.34g/eraa, and it evenly mixes the holder case by model requirements in the back with silica sand in stirrer for mixing by a certain percentage, begins to make sand mold and loads onto kiln car subsequently and push drying kiln and dry.Now, is the Corhart Zac-block die quality quite high, but crackle still often appears in the fused alumina zirconia fused cast refractories, so how solves this technical problem?

Three, summary of the invention

At above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of with the core in the through hole fused alumina zirconia fused cast refractories mould, can effectively solve the problem that occurs crackle in the production of fused alumina zirconia fused cast refractories.

The technical scheme that the utility model solves is, comprises core block, and core block has two vertically at least, and the gap of 1-5mm is arranged between the core block, is filled with combustible material in the gap.

The utility model is simple in structure, easily manufactures, and result of use is good, and by the fused alumina zirconia fused cast refractories flawless that its manufacturing is produced, quality is good, and the yield rate height effectively reduces the production cost of fused alumina zirconia fused cast refractories and core.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

Shown in Fig. 1-12, the utility model comprises core block, and core block 1 has two vertically at least, and the gap 2 of 1-5mm is arranged between the core block 1, is filled with combustible material 3 in the gap.

Said gap 2 its spacings are a kind of among 1mm, 2mm, 3mm, 4mm, the 5mm; Said core block is a kind of of 2,3,4,5 compositions; The core that said core block is combined into is cylindrical or taper or up-small and down-big toroidal; Said combustible material is a kind of of cardboard, plank or wood particle board.

The main cause that crackle appears in band through hole fused alumina zirconia fused cast refractories is, after fused alumina zirconia electric smelting liquid enters mould, in the cooled and solidified process, be contraction process, and core at first is the thermal expansion of core chance, be that cooling is shunk then, the amount of contraction of fused alumina zirconia fused cast refractories crackle just occurred greater than the core amount of contraction, causes substandard products.By said structure as can be seen, the utility model axially is divided into several with core along it, fill combustible material therebetween, when using aborning, match with other compacting tool set, after fused alumina zirconia electric smelting liquid enters mould, when the fused alumina zirconia fused cast refractories shrinks, force the pitch smaller between the core, the carbonization under the condition of high temperature anoxic of combustible material between the core, can adapt to the pitch smaller between the core, just significantly reduce the generation of crackle, effectively improve the quality of product, guaranteed product percent of pass, having reduced manufacturing cost, is the innovation in the fused alumina zirconia electric smelting, and economic and social benefit is remarkable.
