Abstract

The invention relates to a mould for preparing an electric smelting zirconium adamantine spar rotating cylinder brick, which can effectively solve the problem that the existing special type electric smelting zirconium adamantine spar brick is difficult in molding, poor in molding quality and large in production difficulties. The method is that an outer mould is placed outside a lower inner core, the outer mould and the lower inner core are homocentrically arranged on a bottom fixing piece, an upper inner core is homocentrically arranged on the lower inner core, the lower inner core, the upperinner core and the upper portion of the outer mould are fixed together through upper fixing pieces, the bottom fixing piece is fixed on a base, a pouring conduit which is vertical to the base and parallel to the lower inner core is arranged on the upper portion of one side of the bottom fixing piece, the pouring conduit is communicated with a space on the upper portion of the base, a pouring deadhead is arranged on the upper portion of the pouring conduit, and a feeding head homocentric with the upper inner core is arranged outside the upper inner core and arranged above the upper fixing pieces. The mould for preparing the electric smelting zirconium adamantine spar rotating cylinder brick effectively uses characteristics that resin sands are hard and dry and complex moulds are integrally made, guarantees product accuracy, uses water-glass sands and white corundum, improves rate of finished products, avoids color and luster pollution of products, and improves later-stage processing efficiency.

Description

The mould of preparation electric smelting zirconium adamantine spar rotating cylinder brick
Technical field
The present invention relates to mould, particularly a kind of mould for preparing electric smelting zirconium adamantine spar rotating cylinder brick.
Background technology
The AZS production is that the feed liquid that fusing in electric smelter is good is poured in the sand mold mould cooled and solidified aftershaping into.Goods are because its product performance, be subjected to the impact of material property, production technology and production equipment during production, so large for some special-shaped products (3 gage above), super wide, overlength, ultra-thin, disproportionate brick material forming difficulty, yield rate is low, the product of moulding easily produces defective, wherein, the rotating cylinder brick belongs to Idiotype product, complex manufacturing, existing mould is difficult to moulding, and Forming Quality is poor, and production difficulty is large, so the improvement and bring new ideas of its mould is imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defective of prior art, the present invention's purpose just provides a kind of mould for preparing electric smelting zirconium adamantine spar rotating cylinder brick, can effectively solve existing Idiotype Corhart Zac-block difficult forming, and Forming Quality is poor, the problem that production difficulty is large.
The technical scheme that the present invention solves is, first outside the inner core of bottom, place external mold, external mold places on the fixture of bottom with the bottom inner core is concentric, be placed with one heart the top inner core on the inner core of bottom, the bottom inner core, the top of top inner core and external mold is fixed together by upper stationary part, the bottom fixture is contained on the base, bottom fixture one upper lateral part is provided with perpendicular to base, and be parallel to the cast conduit of bottom inner core, the cast conduit is connected with the space on base top, cast conduit top arranges the cast rising head, and the upper stationary part top is outside equipped with the feeding head concentric with the top inner core at the top inner core.
The present invention has effectively utilized resin sand dry from doing something in disregard of obstacles, and the characteristics of integral manufacturing complicated die guarantee Product Precision, uses in conjunction with water-glass sand and white fused alumina simultaneously, improves yield rate, avoids product color to pollute, and improves post-production efficient.
Description of drawings
Fig. 1 is the structural front view of product of the present invention.
Fig. 2 is the upper stationary part top view of product of the present invention.
Fig. 3 is the base vertical view of product of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated.
Shown in Fig. 1-3, the present invention is first at bottom inner core 9 outer placement external molds 7, external mold places on the fixture 4 of bottom with the bottom inner core is concentric, be placed with one heart top inner core 8 on the inner core of bottom, the bottom inner core, the top of top inner core and external mold is fixed together by upper stationary part 3, the bottom fixture is contained on the base 6, bottom fixture one upper lateral part is provided with perpendicular to base, and be parallel to the cast conduit 5 of bottom inner core, the cast conduit is connected with the space on base top, cast conduit top arranges cast rising head 1, and the upper stationary part top is outside equipped with the feeding head 2 concentric with the top inner core at the top inner core;
Described external mold and top inner core, bottom inner core are the cylindrical shape that resin sand integral body is made; Base, cast conduit, feeding head and cast rising head are water-glass sand and make; Upper stationary part and bottom fixture are that the white fused alumina material is made;
Described water-glass sand is by the weight ratio meter: the thin Gui Sha of 80 ~ 100 purposes ︰ diameter is the thick Gui Sha ︰ waterglass=35 ~ 40 ︰, 50 ~ 55 ︰ 8 ~ 10 of 3 ~ 5mm, after mixing, the mould of packing into, after the compacting under 300 ℃ of temperature drying forming, described waterglass density is 1.45 ~ 1.56g/cm 3
Described resin sand is by by weight: 40 ~ 70 order Gui Sha ︰ Fu Nan Shu Zhi ︰ curing agent=100 ︰, 1.35 ~ 1.5 ︰ 0.6 ~ 0.9, and the mould of packing into after the mixing leaves standstill from hard moulding (namely under natural environment, dry, hardened forming is as follows voluntarily); Described curing agent is the sulfonic acid curing agent;
Described upper stationary part and bottom fixture all are by the Bai Gangyu ︰ waterglass of weight ratio meter=90 ~ 100 ︰ 7 ~ 9, after mixing, and the mould of packing into, compacting is drying forming under 300 ℃ of temperature afterwards, and described waterglass density is 1.45 ~ 1.56g/cm 3, the granularity≤1mm of described white fused alumina.
Described upper stationary part 3 inner faces have convex clip 10, to guarantee fixed effect; Be the groove shape above the described base 6, cross recess 11 is arranged in the groove; Interior core outer surface, external mold inner surface all are coated with and are brushed with zirconium matter fireproof coating layer, when avoiding directly contacting with product, product are caused dye discoloration.
When the present invention uses, feed liquid melt good after, pour into from the cast rising head, the cast conduit of flowing through, groove above the base enter mould from bottom to up, stop to the feeding head height.Adopt from bottom to up pouring type and arranging of feeding head can improve cast compactness, improve the quality of products, the product that the present invention produces all meets or exceeds state specified standards bulk density (tight section) 〉=3.7g/cm through test of many times 3, the product test result that the present invention produces is 3.8-3.85 g/cm 3Whole unit weight state specified standards>3600 Kg/m 3, the product test result that the present invention produces is 3650-3700Kg/m 3Apparent porosity (tight section) state specified standards≤2%, the product test result that the present invention produces is 0.8-1.2%.
