Good Thermal Shock Resistance Zirconia Glass Furnace Used Blocks
sintered zirconia bricks refractories belong to sintered ZrO2_Al2O3_SiO2 products family along with Zircon Mullite, Bonded AZS, Zirconia Corundum and Rebunded Fused Mullite bricks. Sintered ZrO2-Al2O3_SiO2 products like AZS have good resistance to alkali vapoor and thermal shock. and are mainly used in glass furnaces, they can stand aggressive conditions in contact with molten glass. Typical applications are superstructures, skew blocks, wall bricks and upper-checker in regenerators, paving, sub-paving and forehearth blocks in float glass furnaces. Rebunded Fused Mullite bricks (MFZ-6) is used as pure-oxygen burner blocks in alkali-free glass furnaces, crown blocks and arch blocks in ceramic frit furnaces or used in the areas of high tempreture and high thermal stress in oter industrial furnaces.
We offer complete line of sintered zirconia bricks - Bricks, Mortars, Castables at the most competitive prices, and we offer technical supports such as glass furnace design and installation consultant upon request.
We can produce sintered zirconia corundum brick according to your specification or requirements. Special detailed bricks technical data sheet are avalible upon request.
