Description
Technical field
The present invention relates to heat proof material casting technology field, in particular to a kind of vertical laminatings based on V method casting moulds
Device.
Background technology
At present, domestic castable refractory production is mostly using conventional waterglass combination quartz sand sand mold, using this technique
Sand mold prepared by technology, first, causing the poly- cinnamic acid degree of polymerization uneven since waterglass is easy to aging, adhesion strength reduces, and causes water
The up time of glass sand shortens, and craftsmanship degenerates.It causes sand mold Strength Changes big, the phenomenon that Sand Penetration usually occurs,
Make product surface out-of-flatness, dimensional discrepancy is big.Second is that since Sodium Silicate Bonded Sand at High Temperature intensity is poor, in the bad situation of radiating condition
Under, softening is occurred by the effect of high temperature solution and necessarily leads to deformation, distortion, leads to product appearance defect.Third, common waterglass
Sand mold cannot be defeated and dispersed, without deformability, can cause the cracked defect of product.Also, water-glass sand can only be disposable, no
Conducive to recycling, waste of material is big.Fourth, the baking of water-glass sand plate is yielding, sand mold geometric dimension is influenced.Moreover, baking sand plate loss
Take mass energy, improve product cost.
Although by improve the adhesion strength of water-glass sand, operability, the elevated temperature strength of water-glass sand and
The collapsibility of water-glass sand, can more or less improve the technique and performance of water-glass sand, but still be difficult to eliminate waterglass
The drawbacks of residual strength of sand is high, and knockability is poor, and casting is difficult to sand removal, and regenerating used is using difficulty.At present, founding is provided in the country
The sand mold technology of preparing of refractory materials manufacturing enterprise there is no ability to carry out similar to this still in the technological phase of chemical bonding moulding
The technological development of research topic task.
Now, external production castable refractory is mainly using high-tech such as the quartz sand sand mold of resin-bonded and graphite mo(u)lds
The sand mold technology of preparing of content, to produce the castable refractory of high quality.So as to fulfill castable refractory Near net shape casting,
Accomplish no surplus or connect Near net shape processing, greatly improve castable refractory castability.
It is right as user is higher and higher to castable refractory dimension precision requirement and environmental requirement that enhance increasingly
Becoming more meticulous the needs of casting in castable refractory will be more and more urgent, and V method production-line techniques are come into being, V method production line works
Skill is to be combined vacuum technique with dry sand mold moulding, binding agent is added without in sand mold, water drinks other additives.This moulder
Skill is the cavity surface and sealing backside by sand mold using plastic film, by air in positive empty set system extraction type, causes sand
The inside and outside pressure difference of type makes molding sand fastening molding, so as to form required casting mold cavity, through by it is subsequent place special riser and and
Case operates, and completes the novel sand mold moulding of founding material.
Wherein in V methods production technology, mold overlay film is one of very important link in entire technique, now be yet there are no related
In the vertical laminating device based on V method casting moulds.
