This product can also be produced as the big straight block.Recommendations:This product is designed for the sidewalls of flame furnaces with embedded melted bottoms, for total, security with average pulls and campaign lengths.Shape and size:Only straight brick is available.NH-36A:Introduction:Material is electro-fused Alumina-zirconnia-silica, with 36% ZrO2 This product can be made into complex and varied shapes and to be superstructure of different kinds of glass furnaces.Typical chemical composition:Al2O3 52.85% ZrO2 36% SiO2 10% Na2O、B2O 熔剂0.9% TiO2、Fe2O3 0.25%Crystallographic analysis: Alumina (corundum) 51%Zirconia 35%Vitreous phase 14%True specific gravity: 4050kg/m3Cold crushing strength 215MpaRefractoriness under load 1700CNH-36A PT-WSWhen AZS-36A is used for crowns, the brick surfaces must be grinded by diamond grinder to ensure tight contact between bricks, and then become a firm monolithic structure. Only NH-36A PT and DY-36A WS are available. (NH-36A 可完成PT和WS浇铸砖的制造。该产品系列作为顶碹砖材料时，砖与砖接触面要用金刚石磨具研磨加工，以确保砖与砖之间紧密接触，从而形成牢固的整体结构。Recommendations:AZS-36A has low exudation, high cold crushing strength and excellent alkali resistant capabilities, so it begins to be used for superstructures, frontwalls, backwalls, crowns, etc, in glass furnaces.NH-41:IntroductionMaterial is electro-fused Alumina-zirconnia-silica, with 41% ZrO2 The good castability of this material enables the production to be a great variety of straight or approximate bricks.Typical chemical composition:Al2O3 45.75% ZrO2 41% SiO2 12% Na2O(以碳酸钠的形式加入)、B2O 熔剂1% TiO2、Fe2O3 0.25%在此基础上采用部分脱硅锆英石砂作原料即可制成41#的砖Crystallographic analysis: Alumina (corundum) 42%Zirconia 41%Vitreous phase 17%True specific gravity: 4100kg/m3Cold crushing strength 200MpaRefractoriness under load 1700CNH-41WS:Introduction：This kind of bricks is practically free of voids and has a very homogeneous internal structure with fine anti-corrosion property.
