The standards for refractory materials used in glass kilns mainly include the following aspects:
Mechanical Strength: Refractory materials need to have sufficient mechanical strength to withstand mechanical loads at high temperatures. This is key to ensuring the structural stability of the kiln and preventing it from collapsing or being damaged.
Refractory: The refractory material should have high refractory resistance and be able to operate stably for a long time at high temperatures to prevent material ablation or melting caused by excessive temperature inside the kiln.
Chemical stability: Refractory materials need to be chemically stable, able to resist the erosion and chemical corrosion of molten glass, and ensure the stability of the internal environment of the kiln.
Thermal shock resistance: Refractory materials should have good thermal shock resistance and be able to maintain structural stability when the temperature changes greatly, preventing the kiln from being damaged due to excessive thermal stress.
Material matching: Refractory materials of different materials should avoid contact reactions during masonry construction to prevent damage to the kiln or impact on glass quality due to material mismatch.
Pollution control: Refractory materials should not pollute the glass liquid to ensure the quality and transparency of the glass.
In the selection process of refractory materials for glass kilns, factors such as material cost, construction difficulty, and maintenance also need to be considered. At the same time, with the continuous advancement of science and technology, the research and development and application of new refractory materials have also provided more options for the development of glass furnaces.
In short, the standards for refractory materials used in glass kilns are multifaceted, and factors such as material performance, use environment, and economic costs need to be comprehensively considered to ensure the stable operation of the kiln and the high-quality production of glass.
