Riser Design of Cast System of Fused Zirconia-Alumina-Silica

Abstract:

Fused cast Zirconia-Alumina-Silica material (AZS) is the key refractory to glass furnace. In order to reduce production cost and optimize production process, the influences of riser position and riser size on temperature gradient, solidification time, residual melt modulus, solidification fraction, and cooling rate of cast system were studied by the finite element simulation method according to the brick size of 600 mm × 400 mm × 300 mm. It turned out that it would be more efficient in feeding when riser located at the center of maximum surface of a brick or when the height of riser is 250 mm-270 mm, while the volume ratio of brick to riser is 2.95-2.74, on condition that the size of riser upper surface is 450 mm × 450 mm and the bottom 150 mm×150 mm.
