　　棕剛玉簡介：Introduction of brown fused alumina

　　棕剛玉，俗名又稱金剛砂，是用礬土、碳素材料、鐵屑三種原料在電爐中經(jīng)過融化還原而制得的棕褐色人造剛玉，故為此名。棕剛玉主要化學成份是 AL2O3，其含量在94.5%-97%，另含有少量的Fe，Si，Ti等。

　　Brown fused alumina, local name, also known as carborundum, is made of alumina, carbon materials, scrap iron three kinds of raw materials in electric furnace melting reduction and made of brown alundum, reason for this name.Brown fused alumina is mainly chemical composition is AL2O3, and its content from 94.5% to 94.5%, the other contains a small amount of Fe, Si, Ti, etc.

　　棕剛玉理化指標：Brown fused alumina indicators

　　棕剛玉主要用途：Brown fused alumina is mainly USES

　　(1)由于有耐高溫、耐腐蝕、高強度等性能，故用澆鋼滑動水口，冶煉稀貴金屬、特種合金、陶瓷、煉鐵高爐的內(nèi)襯(墻和管);理化器皿、火花塞、耐熱抗氧化涂層。

　　(1) with high temperature resistance, corrosion resistance, 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)由于有硬度大、耐磨性好、強度高的特點，在化工系統(tǒng)中，用做各種反應器皿和管道，化工泵的部件;做機械零部件、各種模具，如拔絲模、擠鉛筆芯模嘴等;做刀具、模具磨料、防彈材料、人體關節(jié)、密封模環(huán)等。

　　(2) with 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)剛玉保溫材料，如剛玉輕質(zhì)磚、剛玉空心球和纖維制品，廣泛應用于各種高溫爐窯的爐墻和爐頂，既耐高溫又保溫。棕剛玉粒度砂是由人工精選棕剛玉塊,采用對輥、球磨、巴馬克等設備加工而成，粒度由F8-F325.主要用于拋光、研磨、工業(yè)磨削等，還可以按客戶要求進行水洗、酸洗處理等方法加工，能夠滿足客戶的不同需求。

　　(3) corundum thermal insulation material, 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, the mark and granularity by F8 - F325. Mainly used for polishing, grinding, grinding industry, etc., can also according to customer requirements for water washing, acid pickling treatment methods such as processing, able to meet the different needs of customers.

　　低碳棕剛玉經(jīng)過爐前和特殊工藝的再處理，降低棕剛玉中殘余碳的含量，使產(chǎn)品在使用中不粉化、不爆裂、韌性大是磨料磨具行業(yè)，耐火材料行業(yè)的首選原料。主要用于陶瓷磨具、高檔磨具、有機磨具、砂帶、涂附磨具等，　根據(jù)殘?zhí)己糠譃椋红褵貏傆馛 ≤0.05%、低碳棕剛玉C ≤0.10%、普通棕剛玉C ≤0.15%。

　　Low carbon corundum and special process in the run-up to the furnace processing, reduce the residual carbon content in the brown fused alumina, make the product in use not pulverization, not burst, great toughness is abrasives industry, refractory industry of choice for raw materials.Mainly used in ceramic grinding tool, high-grade abrasive, abrasive, abrasive belt, coated with organic grinding tool, etc., according to the residual carbon content is divided into: calcined corundum C 0.05% or less, low carbon corundum C 0.10% or less, the common brown corundum C 0.15% or less.
