Product Name: High Zirconia Azs Bricks & Blocks for Glass Bending Furnace Material: Alumina Block Shape: Brick Type: Heat-Resistant Material Feature: Long Time Materials, Instant Materials Refractoriness (?): 1770< Refractoriness< 2000 Trademark: FM Transport Package: Packed in Water Proof Wooden Pallets Specification: AZS 33 & 41 Origin: China HS Code: 69022000 Product Description Material and TechniqueZirconia corundum mullite refractory bricks(AZS bricks) are mainly for glass furnace. use special grade bauxite and zirconite concentrate as the raw materials, are produced by reaction bonded process, introducing ZrO2 into mullite matrix, are high grade refractories.PropertiesAZS bricks & blockscan be use for glass melting furnace and fiber glass furnace, because of the following characteristics:1. High refractoriness;2. Good thermal shock resistance;3. Good creep-resisting property;4. Good chemical stability;5. Good high temperature strength and volume stability.6.High erosion resistanceApplicationAZS brickswhich have the features of properly sintered, porosity at normal levels, good high temperature strength and volume stability can be used for L-shaped suspended arch building in glass furnace.SpecificationsItemProductsAZS33AZS 41Chemical CompositionAl2O3 %≤50≤45ZrO2 %32-3640-44SiO2 %≤16-16.513Na2O+K2O %≤1.51.3Bulk density g/cm33.63.9Cold crushing strength MPa≥300≥300Refractoriness under load(0.2MPa,0.6%) ºC≥1680≥1680Exudation Temperature of Glass Phase≥1400≥1410Bubble Separation Ratio (1300ºC*10h)≤1.5≤1.0Anti-corrosion rate of glass liquid 1500ºC*36h(mm/24h) %≤1.45≤1.2Apparent density g/cm3PT≥3.45≥3.7ZWS≥3.6≥3.9WS≥3.7≥4.0Hitech Material Group is a specialized group in refractory materials and insulation products.
