Two commonly used zirconium ramming materials

The performance of refractory materials in resisting high-temperature molten glass corrosion is an important factor in determining the life of glass kilns and the quality of glass products. Zirconium ramming mass can be widely used in the bottom of glass kilns. In addition to its good integrity, good sealing, and strong adaptability, it also benefits from the superior corrosion resistance and ultra-high refractoriness of zirconium materials. Zirconium aggregate is the skeleton of zirconium ramming materials, which plays an important role in the high-temperature physical properties of zirconium ramming mass. Currently, two main types of zirconium ramming mass are used for glass kiln bottoms: electric melting AZS ramming mass, and the other is zircon ramming mass.

The fused AZS ramming material is made by crushing the fused zirconium corundum brick into particles of about 5mm as aggregate and then mixing it with other auxiliary materials. It retains the advantages of fused zirconium corundum bricks, has strong resistance to glass liquid erosion, low porosity, extremely stable performance, and can well inhibit the invasion of glass liquid and metal. The zircon ramming material is made by adding a certain proportion of crushed sintered zircon brick fragments to the zircon mud powder as aggregate, and then adding other auxiliary materials. It has high refractoriness and good resistance to glass liquid erosion. When constructing the two types of zircon ramming materials, you only need to add an appropriate amount of water in proportion to mix them. After mixing evenly, make the ramming materials moist and loose, then ram them, and sinter them at high temperature to form a solid whole. The construction abandons the previous use of phosphoric acid as a binder, which is safer and more convenient.
