Fused Cast 33 ＃ AZS Block (RTK-AZS33)
RTK-AZS33, a high-performance refractory material, is particularly superior in preventing molten glass from being contaminated. It has little tendency to cause stones, bubbles and matrix glass phase precipitation in the glass. And it has strong resistance to acid and alkaline slag as well as molten glass, making it suitable for use in harsh chemical environments. It is applicable to the upper structure of the melting end , the side wall of the working pool, the paving blocks and forehearth, etc.
Fused Cast α-β-Alumina Block(RTK-M)
RTK-M is composed of about 50% each of α-alumina and β-alumina , and the interlocking of the two crystals forms a very dense structure with excellent resistance to strong alkalis.
Its resistance to erosion of molten glass is comparable to that of AZS in the temperature range below 1350℃. Since it contains almost no impurities such as Fe₂O₃ and TiO₂, the matrix glass phase is very small, and it has the excellent property of not contaminating the molten glass by minimizing the occurrence of foreign matter such as bubbles when in contact with the molten glass.
Therefore, it is the most suitable for working pool wall, pavement, material channel and channel of high-grade glass furnace.
