Sinunterdagi korund g'isht - bu sinovdan o'tgan zich alumina klinkeridan tayyorlangan refrakt mahsulotidir. Sinundy Corbum g'isht yuqori haroratda, yuqori haroratda barqaror ishlash, yaxshi mexanik kuch va xona haroratida va yuqori haroratda ko'nikmalarga ega. Bu metall korroziyaga, oksidlanish va pasayish uchun juda yaxshi qarshilikka ega.
Sinlangan korund g'isht ishlab chiqarishda ishlatiladigan xom ashyolar, kiladi va mayda miqyosli zamin (ba'zan esa kristalli tuzilishni yaxshilash uchun yuqori darajadagi sanoat aluminasi (ba'zan kam miqdordagi mgl qo'shimchalari) yashil tanaga tashlanadi va 1850 darajadan yuqori darajada hisoblanadi. Yuqori haroratli ravishda ochilish yog 'tuzilishidagi o'simtalarni maydalashtiradi va don hajmini 25 dan 40 martaga ko'paytiradi. Yaxshi sinunterdagi korund kristallari zich plastinka o'xshash tuzilishiga ega.
Sing'adir Sinundum 3% dan kam va asosiy zichlik 3,6 0 g / sm3 g'isht tayyorlash uchun kerakli zarracha hajmiga maydalanadi. The physical and chemical properties of the raw materials are as follows: Al2O3 99.17%~99.31%, SiO2 0.19%~0.26%, Fe2O3 0.09%~{{20}}.14%, CaO 0. {{27} ~ 0 0 0 {{33} {{33} {{33} {{33} {Suv singdirish 0,6% ~ 1,0%, yasalgan g'ovaklilik 2.3% ~ 3,7%, asosiy zichligi 3.60 ~ 3.80g / sm / sm3.
Mahsulot tavsifi
The production process of sintered zirconium corundum bricks is to crush the sintered corundum into 3mm coarse particles and some fine powders less than 0.074mm, and some are mixed with a small amount of clay and other binders, and then formed with a high-pressure friction brick press or an oil press. After drying, the bricks are loaded into a high-temperature kiln for firing. Generally, the sintered zirconium corundum bricks with higher purity have a firing temperature of 1750~1800℃. If a small amount of clay or additives are added, the firing temperature can be 1600~1700℃. The physical and chemical properties of sintered corundum bricks are as follows: Al2O3>95%, refractoriness greater than 1790℃, apparent porosity less than 14%, bulk density 3.22g/cm3, compressive strength>1 0 0 MPA, krepal tezligi (1550 daraja, 50 daraja, 50 dona) 0,5%, yumshatish harorati (T0.6) 1700 darajadan katta (T0.6) yuklash (T0.6). Sinr qilingan korunddan yasalgan grenn qilingan korundlik g'isht juda poklik va ajoyib jismoniy xususiyatlarga ega. Sinilgan tsirkonyum gish-mishlar asosan portlash pechlarida va pechdan tashqarida ishlaydigan pechlarda qo'llaniladi. Shuningdek, ular kimyo va elektron sanoat kabi sanoat kabinalarida keng qo'llaniladi.
