Supplier manufacturer ZA25% ZA40% F12 Slide gate fused zirconia alumina
Fused zirconia alumina is produced by putting rich aluminum, zirconium materials and additives in electric furnace, smelting with high temperature above 2000°C,cooling down with special technology, and compacting with Barmac plastic, which has the characteristics of tenacious texture, dense structure and high strength.
It takes the advantages of high strength, high toughness, high temperature resistance, which can manufacture heavy-duty wheel with high performance, and has achieved very good results in grinding steel, cast iron, heat-resistant alloy steel, titanium alloys, aluminum alloys and austenitic alloy steel. And it is widely used in the production of refractoriness in the steel industry such as continuous casting and rolling, flow channel, and zirconia brick as well.
It is classified into ZA 25 and ZA 40 as the content of Zr02.
