【棕刚玉简介】

      棕刚玉是生产高温耐火材料和磨具磨料以及喷砂的主要原材料。棕刚玉是以高铝矾土、焦碳（无烟煤）为主要原料，在电弧炉内经2200度高温冶炼精制而成，主要化学成分为AL2O3、TiO2环含有少量的SIO2和Fe2O3等，显微硬度HV1800-2200，韧性比SIC高，用它制成的磨具磨料，适于磨削抗张较高的金属，如各种通用钢材、可锻铸铁、硬青铜等，也可制造高级耐火材料。我们通常使用的棕刚玉都是通过电熔法而得到的，电熔棕刚玉主要用在耐火材料，砂轮。棕刚玉的生产工艺方法主要有两种即固定炉棕刚玉和倾倒炉棕刚玉。

Brown fused alumina is manufacturing high temperature refractory and abrasive abrasive as well as the main raw material for sand blasting. Brown fused alumina is bauxite, coke, anthracite) as the main raw material, Canon 2200 degrees high temperature smelting in arc furnace refined but become, the main chemical composition of AL2O3, TiO2 loop contains a small amount of SIO2 and Fe2O3, microhardness HV1800-2200, high toughness than SIC, use it made of abrasive abrasive, suitable for grinding the high tensile metals, such as all kinds of steel, malleable cast iron, hard bronze, etc., also can make advanced refractories. We usually use brown fused alumina is fused with the law, fused corundum is mainly used in refractory materials, grinding wheel. Brown fused alumina production process there are two main types namely fixed furnace corundum and dumping of furnace brown fused alumina.

【棕刚玉冶炼方法】

     1、流放发：连续生产，自动化水平高，但投资大，结构复杂，适合于大功率冶炼。

      2、倾倒法：连续生产，机械化水平高，投资较小，生产效率好，目前使用普遍的一种方法。

      3、固定法（熔块法）间断生产，机械化水平低，但投资小，设备简单，工艺方便，目前小型磨料厂进行棕刚玉冶炼的主要方法。

1, exile: continuous production, high automation level, but the investment is big, complicated structure, suitable for high power smelting.

2, dumping law: continuous production, high mechanization level, less investment, good efficiency, a method of currently used widely.

3, fixed method (frit method) continuous production, low level of mechanization, but the small investment, simple equipment, convenient process, the current small abrasive factory is the main method of brown fused alumina smelting.

【棕刚玉特点】

      1、由于有耐高温、耐腐蚀、高强度等性能，故用浇钢滑动水口，冶炼稀贵金属、特种合金、陶瓷、炼铁高炉的内衬（墙和管）；理化器皿、火花塞、耐热抗氧化涂层。   

      2、由于有硬度大、耐磨性好、强度高的特点，在化工系统中，用做各种反应器皿和管道，化工泵的部件；做机械零部件、各种模具，如拔丝模、挤铅笔芯模嘴等；做刀具、模具磨料、防弹材料、人体关节、密封模环等。   

      3、棕刚玉保温材料，如刚玉轻质砖、刚玉空心球和纤维制品，广泛应用于各种高温炉窑的炉墙和炉顶，既耐高温又保温。棕刚玉粒度砂是由人工精选棕刚玉块,采用对辊、球磨、巴马克等设备加工而成，粒度由F8-F325.主要用于抛光、研磨、工业磨削等，还可以按客户要求进行水洗、酸洗处理等方法加工，能够满足客户的不同需求。

      4、棕刚玉磨料具有纯度高，结晶好，流动性强，线膨胀系数低，耐腐蚀的特点。应用过程中具有不起爆、不粉化、不开裂的特点。是棕刚玉质耐火材料的骨料和填充料。

1, due to the high temperature resistant, corrosion resistant, high strength, such as performance, so use casting steel slide gate, and special alloy smelting rare metals, ceramics, blast furnace lining (wall and pipe); Physical and chemical vessels, spark plugs, heat-resistant oxidation coating.

2, because of the characteristics of high hardness, good wear resistance, high strength, in the chemical industry system, used for all sorts of reaction vessel and pipe, chemical pump parts; To do mechanical parts, all kinds of mold, such as wire drawing die, such as pencil lead mold mouth; Do abrasive tool, mould, bulletproof material, human body joint, seal die ring, etc.

3, brown fused alumina insulation materials, such as corundum light brick, alumina hollow ball and fibre products, widely used in various high temperature furnaces of furnace wall and furnace top, high temperature resistant and heat preservation. Brown corundum sand particle size is by the artificial corundum block, using the equipment such as roller, ball mill.

4, brown fused alumina abrasive with high purity, good crystallization, strong liquidity, low linear expansion coefficient, the characteristics of corrosion resistance. Application is not in the process of initiating, pulverization, cracking characteristics. Brown is just the quality of the jade the best refractory aggregate and filling material.

【棕刚玉用途】
