AZS refractory bricks are called fused zirconia corundum bricks. It is made by completely melting the raw materials and casting them into a mold, cooling and solidifying them. Mainly serving the use of glass kilns. The shrinkage caused by volume shrinkage during the condensation process of this product is a special consideration when using it. The casting methods of AZS refractory bricks (fused zirconia corundum bricks) include ordinary casting, inclined casting, non shrinkage casting, and quasi shrinkage casting. The different casting methods of AZS products can meet the usage requirements of various parts of ceramic frit kilns, bubble alkali kilns, and glass kilns. It is resistant to erosion, corrosion, and has a long service life. Currently, the commonly used method is electric melting oxidation casting.
There are three important driving forces behind the development of AZS refractory bricks. Firstly, glass manufacturers usually need to modify the quality of glass supply and demand in order to maintain a minimum. The second is the financial requirements for glass kilns to ensure longer furnace operating cycles, and the third is the impact of pure oxygen combustion system. These three requirements usually determine the selection and modification of refractory bricks during kiln repair. These driving forces have also prompted glass manufacturers to choose and modify refractory products during maintenance of their kilns, as well as to introduce new skills when operating for large-scale repair.
The melting pouring of composite aluminum bricks has established its application in the melting pool top, and the important melting high-quality glass pure oxygen combustion pool furnace has been applied. Before the advent of pure oxygen combustion skills, only βˉ Composite aluminum bricks are used for the top structure of the melting pool, and no molten poured composite aluminum bricks are used on the top of the melting pool. Today, regardless of βˉ Aluminum compound α-β Molten aluminum casting products are all used to produce colorful films (screen cones), float glass, and borosilicate glass on some or all of the top of pure oxygen combustion furnaces. Melting cast AZS bricks can generally be used up to 1600 ℃ or 1650 ℃ (for glass products), while using fused aluminum bricks to build the furnace top can operate very successfully at 1700 ℃. This provides better conditions and greater activity for glass manufacturers to produce refractory glass. AZS refractory bricks, high alumina bricks, castables, square bricks, high-temperature mortar, high-temperature fire clay, acid resistant bricks. It has strong vitality in the use of glass kilns.
