Description
Technical field
The utility model relates to electro-melting zircon corundum brick production technical field, and particularly a kind of fusion casting azs is without shrinkage cavity fused cast refractories insulation annealing gas barrier and the heat preserving method adopting this gas barrier.
Background technology
The low state of current glass industry directly affects the interests of refractories industry. and overall situation lower-glass kind is in improvement, upgrading, press lower to the price of refractory materials, higher to the specification of quality of refractory materials. for the founding azs fire resistive material product of glass furnace, a key index of its quality is exactly molten heavy, zirconium content 33% and zirconium content 41% to melt heavy industry standard without shrinkage cavity brick be that 3.75. and 3.9. heavily depends primarily in three about the molten of zirconia-corundum refractory brick respectively: 1, melting process, fusing feed liquid will have enough dilutions, feed liquid is rarer, keep the time of the condition of high temperature longer after casting, solution in rising head just has the more sufficient time to carry out feeding to brick body, its pouring temperature index is: the goods teeming temperature containing zirconium amount 33% is 1780 DEG C-1800 DEG C. the goods teeming temperature containing zirconium amount 41% is 1820 DEG C-1840 DEG C, 2, the ratio of rising head and brick body: rising head is larger, and solution is more, heat savings are more, to be more conducive in rising head solution to the feeding of brick body, but rising head are larger, larger for enterprise's waste, because emit notch portion not to be product section, can only regard recovery raw material and use, 3, the quality of lagging material: need the insulation annealing process having about ten days in insulation can after Corhart Zac-block casting, the heat insulation effect of its lagging material is also determine that goods melt a heavy link, high insulating effect, the liquid time of goods is just long, solution in liquid time length i.e. rising head has time enough to carry out feeding more fully to brick body. thus reach the heaviest and moltenly heavily meet index and be even better than index. Corhart Zac-block molten weight deficiency i.e. interior solid degree inadequate, the erosion of not resistance to glass metal, glass furnace can be directly caused to reduce work-ing life. especially for the Corhart Zac-block of melting pool part. molten heavy not enough goods glass enterprise can be refused to accept. and the molten heavily higher fused cast refractories quality of the Corhart Zac-block for glass kiln melting tank part is better, its reason molten heavily highlyer shows that feed liquid melted state is good, the liquid time after casting is long, create brilliant picture combination and be more tending towards perfect, liquid lower thermal stresses more easily discharges, the crackle ratio of zirconia-corundum refractory brick is lower, how just can reach these effects, it is the problem that those skilled in the art are concerned about.
