JXMZ-75A
JXMZ-75A
The magnesia-zirconia brick is made mainly from high-purity fused magnesia and zircon concentrate by high-pressure forming and high-temperature firing. It has good thermal shock resistance, strong resistance to SO₂ attack and flue-gas erosion, and withstands high temperature. It performs very well at the top of the regenerators of large float-glass furnaces not fired with petroleum coke.
