1,Description of Chrome Brick For Glass Fiber Furnace
The main raw materials of chrome oxide bricks for glass fiber furnace are chrome oxide and alumina, or a small amount of zirconia is introduced and fired at high temperature in a shuttle kiln. The content of chrome oxide is not less than 50%. The product has excellent corrosion resistance, high strength, excellent wear resistance, high temperature resistance and good peeling resistance.
Chrome oxide is converted into neutral refractory brick, which has weak reaction with acidic and alkaline refractory materials at high temperature, but has strong resistance to the corrosion of various glass liquids. Therefore, it has good application effect in alkali free glass fiber furnace, and is mainly used in the high-temperature parts of the furnace, such as the upper tank wall, the flow hole, the feeding port, etc., which effectively extends the furnace life.
2,Performance parameters of Chrome Brick For Glass Fiber Furnace
2, Features:
1) High purity, less impurities
2) At high temperature, it has good compactness and no relaxation
3) Good spalling resistance at high temperature
4) Under high temperature, the corrosion resistance of alkali liquid is good
5) Wear resistance, good erosion resistance
3, Application:
High chromium refractory brick (Cr2O3 ≥ 90%) is mainly used in coal chemical industry, chemical industry furnace, alkali free glass fiber furnace, garbage incinerator and other furnace parts. Chrome corundum brick is mainly used in carbon black furnace, copper smelting furnace, rolling heating furnace slide, tapping platform and so on. The main mineral phase of the product is α - Al2o3-Cr2O3 solid solution, and the secondary mineral phase is spinel. Therefore, the high-temperature performance of the product is very good, such as high-temperature creep performance, high-temperature volume stability, high-temperature strength, high load softening temperature, high-temperature corrosion resistance and slag corrosion resistance. Chrome oxide brick is a kind of high-grade refractory. It has been used in many rolling mills, and its service life is up to 10-18 months. It not only significantly extends the service life of the tapping platform and the tapping tank, reduces the furnace shutdown time, increases the output, reduces the consumption of refractory and maintenance costs, but also reduces the quenching and heating times caused by furnace shutdown maintenance, improves the overall service life of the furnace, and achieves obvious results economic performance
4,Chromium oxide brick manufacturing process: high purity aluminum oxide powder and high purity chromium oxide as raw materials, according to the design proportion of accurate weighing, proportioning, fully grinding and mixing, adding quantitative additive, mixing evenly, pressing into billet, billet drying, after electric fusion or calcination into chrome corundum, chrome corundum after crushing, part of grinding into fine powder, the particles and fine powder according to the best grading for proportioning, adding After the binder is mixed well, it is formed by high tonnage brick press or hydraulic press and sintered at 1800 ℃
5,Our company promises to customers: to provide free technical exchanges and services with customers, and to provide samples to customers free of charge without any sample fees.
6,Achievements generated: Our company has previously shipped 50-200 tons to HkongKong.
