Refractory material development has three main impetus: keep improving quality of glass, The requirement of glass kiln economic cycle to make and use more kiln pure oxygen after combustion system brings the impact.
"Current" a word of electronic industry computer industry can change for several months or even several weeks, while about glass industry development application, refractory material, it is easy to be interpreted as five or ten years. According to the concept of time, we will review the discussion area (more conservative pace) "current" has been changed.
Refractory material changes has three main impetus. The first glass manufacturers for at least to keep and improve quality of glass is often needs. The second glass kiln economy demands to make kiln operation cycle is longer and the third pure oxygen burning system brings the impact. These three requirements often determines the repairing kiln choose when improved refractory materials. These forces also prompted glass kiln maintenance choose when improved refractory products and operation cycle for large scope when adopting new technology.
Molten cast aluminum bricks have melting pool top this part, mainly has established its high quality glass molten pool of pure oxygen furnace combustion is widely used. Before the advent of pure oxygen combustion technology, only ˉ alumina brick is used in the beta melting pool of structure and no molten cast aluminum bricks used melting pool. Now, no matter ˉ beta alpha beta alumina still molten cast aluminum products by production of color television (screen), cone and boron silicate glass float glass furnace pure oxygen burning pool all or part of the roof. Molten cast AZS brick generally can use to 1,600 degrees or 1650 degrees Celsius (depending on glass) and electric stove melt alumina brick can be successfully 17 degrees operation. This glass manufacturers as infusible glass creates better conditions more flexibility.
For many years, molten cast AZS stove has successfully through cooling heating test, to make more than they can use operating cycle. Now, a little experience accumulated the successful implementation of the fused alumina cooling heating stove, when they use to two or more operating cycle reflects the stronger economic vitality. Fused alumina top use observation (hot furnace) observation results show these materials have chemical stability and mechanical stability. The earliest of this obserational study, because when laying neither fused alumina reference material, nor its top application experience.
