Description
Technical field
The present invention relates to fused cast refractories production technical field, particularly a kind of common casting pressing port ring mould of zirconia-corundum refractory brick
And riser sleeve production method.
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 more than 3.75, 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 is configured 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.Common casting pressing port setting is usually up big and down small round funnel-form, and 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 riser is destroyed after brick output,
Be not it is concave be exactly protrusion, brick face out-of-flatness when concave influences 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 during cutting, steady due to smaller
Brick is all a cumbersome labour.Therefore, it is imperative to improve and innovate.
