The utility model discloses heat preservation felt subassembly of ingot furnace has and improves heat preservation felt life in the ingot furnace, reduces the oxide shedding, reach corrosion -resistant, keep apart the advantage of effect by force.
Description
Technical field
The utility model relates to the insulation quilt assembly of a kind of ingot furnace, belongs to polysilicon chip and manufactures field.
Background technology
At present, the change that the integrated environment of light volt industry is not substantive, the huge market capacity of whole industry is not effectively discharged, and the impact of the various unfavorable factors of, industry outside inner from industry is still continuing, and the light volt industry Status of development of 2014 also allows of no optimist.
Polycrystal silicon cell still accounts for the major portion of photovoltaic cell, and relative silicon single crystal battery, it bases oneself upon market with relatively low cost, high-level efficiency. And in the face of severe light volt market environment, cost efficiency is the pursuit target that whole industry never becomes. As polycrystal silicon cell upstream trunk production process, polycrystalline ingot casting production cost directly affects the tooling cost of whole polycrystal silicon cell.
In polycrystalline ingot casting production process, solidification felt, as lagging material, is then processed under ingot furnace hot conditions. And solidify felt and oxidizing reaction can occur under the high temperature conditions, easily cause the material on surface to come off, affect yield rate and the production capacity of ingot casting. Therefore seeking a kind of ingot furnace inside holding felt work-ing life of improving, reduce oxide compound and come off, the insulation quilt assembly of the ingot furnace reaching isolation effect corrosion-resistant, strong is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of improve ingot furnace inside holding felt work-ing life, reduces oxide compound and comes off, reaches the insulation quilt assembly of the ingot furnace of isolation effect corrosion-resistant, strong.
The purpose of this utility model is achieved in that
An insulation quilt assembly for ingot furnace, it comprises one piece of top insulation quilt and the sidepiece insulation quilt at four sides, and described sidepiece insulation quilt comprises the first insulation carpet veneer, the 2nd insulation carpet veneer and protective layer from outside to inside successively, and described protective layer adopts carbonization CC plate.
The sidepiece insulation quilt in every face comprises four pieces of arranged in arrays, and wherein the 2nd insulation carpet veneer and protective layer carry out perforate in center separately, is connected by bolt at the tapping of the 2nd insulation carpet veneer and protective layer center separately.
Wherein the first insulation quilt layer thickness is 40mm, and the thickness of the 2nd insulation carpet veneer is 32 ~ 34mm, and the thickness of protective layer is 3mm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is incubated carpet veneer and protective layer owing to sidepiece insulation quilt comprises the first insulation carpet veneer, the 2nd from outside to inside successively, and described protective layer adopts carbonization CC plate, and isolated by protective layer can effectively reduce coming off of oxide compound, it is to increase heat-insulating property. The material that protective layer is selected has the feature of high machinery supporting capacity, lightweight, low-thermal-expansion, remarkable erosion resistance and thermostability, high purity. Insulation quilt is made to be promoted to 18 ~ 24 months work-ing life from 5 ~ June. Therefore the insulation quilt assembly of the utility model ingot furnace has and improves ingot furnace inside holding felt work-ing life, reduces oxide compound and comes off, reaches the advantage of isolation effect corrosion-resistant, strong.
