Selection principle of fused zirconium corundum brick

Before using fused zirconia corundum bricks, you need to first understand the following factors:
(1) The life of the pool furnace;
(2) Glass quality requirements;
(3) The production capacity, that is, the melting rate and the melting temperature,
(4) Insulation, in which parts to maintain heat in order to save fuel;
(5) Economics, that is, the amount of investment.
When using fused zirconium corundum bricks, the requirements should be met to ensure the economics of the pool furnace and facilitate production.
 
1. Ensure that all kinds of fused zirconia corundum bricks used in the construction of glass pool furnaces are required to meet the following basic requirements:
(1) It should have a high softening, melting temperature, and a general refractoriness of not less than 1580 °C.
(2) It has sufficient mechanical strength to resist impact, friction, high temperature and high speed flame, smoke scouring and other mechanical effects.
(3) The high-temperature structure has good strength and can withstand mechanical load for a long time at the operating temperature.
(4) Strong resistance to the erosion of the components of the molten batch, molten glass and gaseous substances.
(5) The pollution to the glass should be small.
(6) Good resistance to rapid cooling and thermal shock (thermal shock).
(7) High temperature volume stability, residual shrinkage or expansion is small.
(8) Thermal capacity, thermal expansion, thermal conductivity and other thermal properties meet the requirements of use.
(9) The shape of the fused zirconium corundum brick is regular and accurate.
(10) Other requirements based on the conditions of use.
The fused zirconium corundum brick must be selected according to the different erosion conditions of each part of the pool furnace.
2. Guarantee the economics of the pool furnace
The selection of fused zirconia corundum bricks should be based on the actual situation, fully study the balance of service life of fused zirconia corundum bricks in all parts of the whole pool furnace, and obtain greater economic effects with less investment. The economy of the glass pool furnace and the balance of the life of the entire pool furnace are fully guaranteed.
 
3. When it is convenient to manufacture and choose fused zirconia corundum bricks, it is necessary to take care of both use and manufacturing. The standardization of fused zirconium corundum bricks and dimensions is conducive to the development of fused zirconium corundum brick production, which is convenient for the design of glass pool furnace design, and is also conducive to construction maintenance. S&P bricks typically cost 30-50% less than shaped bricks. Therefore, the glass pool furnace should be given priority to adopt the standardized fused zirconium corundum brick type.
