【青云】高含量煅燒鋁礬土 鋁礬土熟料產(chǎn)品實拍
產(chǎn)品介紹 
【鋁礬土產(chǎn)品介紹】：
 
    鋁礬土又稱礬土或鋁土礦，主要成分是氧化鋁，系含有雜質(zhì)的水合氧化鋁，是一種土狀礦物，白色或灰白色，因含鐵而呈褐黃或淺紅色。密度2.4-2.5g/cm3，硬度1～3，不透明，質(zhì)脆，極難熔化，不溶于水，能溶于硫酸、氫氧化鈉溶液，主要用于煉鋁，制耐火材料。
 
【鋁礬土產(chǎn)品用途】：
 
    1、煉鋁工業(yè)--用于國防、航空、汽車、電器、化工、日常生活用品等。
    2、精密鑄造--礬土熟料加工成細粉做成鑄模后精鑄，用于軍工、航天、通訊、儀表、機械及醫(yī)療器械部門。
    3、用于耐火制品--高鋁礬土熟料耐火度高達1780℃，化學穩(wěn)定性強、物理性能良好。
    4、硅酸鋁耐火纖維--具有重量輕，耐高溫，熱穩(wěn)定性好，導熱率低，熱容小和耐機械震動等優(yōu)點。用于鋼鐵、有色冶金、電子、石油、化工、宇航、原子能、國防等多種工業(yè)。它是把高鋁熟料放進融化溫度約為2000～2200℃的高溫電弧爐中，經(jīng)高溫熔化、高壓高速空氣或蒸汽噴吹、冷卻，就成了潔白的“棉花”——硅酸鋁耐火纖維。它可壓成纖維毯、板或織成布代替冶煉、化工、玻璃等工業(yè)高溫窯爐內(nèi)襯的耐火磚。消防人員可用耐火纖維布做成衣服。
    5、以鎂砂和礬土熟料為原料，加入適當結合劑，用于澆注盛鋼桶整體桶襯效果甚佳。
    6、制造礬土水泥，研磨材料，陶瓷工業(yè)以及化學工業(yè)可制鋁的各種化合物。
 
    耐火材料行業(yè)所稱的鋁礬土通常是指煅燒后Al2O3>=48%、而含F(xiàn)e2O3較低的高鋁礬土熟料。熟料為灰白淺黃及深灰色，它主要用于高鋁質(zhì)耐火材料，也可用來制作電熔棕剛玉。高鋁礬土熟料是按AL2O3含量及Fe2O3、TiO2、CaO+MgO、K2O+Na2O等雜質(zhì)含量和熟料體積密度與吸水等項指標來分級的。

【 bauxite product introduction 】 :
 
Bauxite is also called the alumina or bauxite, main ingredients are aluminum oxide, hydrate alumina containing impurities, is a kind of soil minerals, white or gray, brown yellow or light red by iron. 2.4 2.5 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle and very difficult to melt, insoluble in water, soluble in sulfuric acid, sodium hydroxide solution, it is mainly used for aluminium, refractory material.
 
【 bauxite product use 】 :
 
1, aluminium industry, used for national defense, aerospace, automotive, electrical, chemical industry, daily necessities, etc.
Diction, precision casting, bauxite clinker made after mold precision casting processed into fine powder, used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.
3, for refractory products - high bauxite clinker refractoriness is as high as 1780 ℃, chemical stability strong, and good physical properties.
4, aluminum silicate refractory fiber with light weight, high temperature resistance, good thermal stability, low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries. It is the high alumina clinker in the melting temperature of about 2000 ~ 2200 ℃ high temperature electric arc furnace, via high pressure of high temperature melting, high-speed air or steam injection, cooling, became a white cotton - silicate aluminum refractory fiber. It can be pressed into fiber blanket, board or woven cloth instead of smelting, chemical industry, glass and other industrial furnace lining brick. Firefighters available refractory fiber cloth to make clothes.
5, magnesia and bauxite clinker as raw material, adding proper binder, used for pouring ladle whole ladle lining has particularly good effects.
6, manufacture alumina cement, abrasive materials, ceramic industry and chemical industry of aluminum compounds.
 
Bauxite is usually referred to in the refractory industry refers to after calcining Al2O3 > = 48%, and contain low Fe2O3 high bauxite clinker. Clinker to pale yellow and dark gray, it is mainly used for high aluminum refractory material, can also be used to make the fused corundum. High bauxite clinker is according to the content of AL2O3 and Fe2O3, TiO2, CaO + MgO style, K2O + Na2O and other impurity content and clinker indicators such as volume density and bibulous to classification.
