Olovga chidamli materiallarning tasnifi
Olovga chidamli materiallarning ko'p turlari mavjud va hozirgi tasniflash usullari o'tga chidamli materiallar taxminan quyidagicha.
1, refrakterlarga ko'ra, oddiy refrakterlarga bo'linishi mumkin: 1580 darajadan yuqori o'tga chidamlilar ~ 1770 darajadan yuqori darajadagi refrakterlar: 1770 darajadan yuqori ~ 2000 darajadan yuqori refrakterlar. refrakterlar 3000 darajadan yuqori.
2, ishlab chiqarish jarayoniga ko'ra, ishlab chiqarish jarayoniga ko'ra, tabiiy tosh, loy quyish, plastmassa qoliplash, yarim quruq kalıplama, quruq presslash, ramming, eritish va quyish kabi mahsulotlarga bo'linishi mumkin.
3, according to chemical composition of a mineral can be divided into(1) siliceous productsSilica brick Si02>93% of the products, quartz glass Si02>99% of the fused products.(2) aluminum silicate productsSilicic acid Si02>65%, AI20s between 15~30%.Clay brick AI203 is between 30 and 48%.High aluminum brick AI203>48% of the products.(3) magnesium productsMagnesia brick: Mg0>85%, magnesia chrome brick Mg055~80% (Cr20:10~30%) products. Chrome magnesia brick: Mg025~55% combined with more chromite products; Magnesia-aluminum brick: magnesia-aluminum cuspite (Mg0-A1203) combined with magnesia-aluminum brick; Mg0·Si02) brick, Mg035~55%.Magnesium olivine (2Dolomite products: products with Ca0>40%, Mg0>35%.(4) Chrome brickCr20330%(5) uglerodli mahsulotlarUglerodli gʻisht: tarkibida uglerod miqdori 70~90% boʻlgan mahsulotlar Grafit mahsulotlari: tarkibida 30% dan ortiq grafit boʻlgan mahsulotlar. Kremniy karbid mahsulotlari: xom ashyo, shamot yoki boshqa noorganik moddalar sifatida Sic bilan mahsulotlar birlashtirilgan.(6) Maxsus refrakterlarYuqori haroratli keramik material: sermet material.
4 Shakli va o'lchamiga ko'ra bo'linishi Shakl va o'lchamiga ko'ra quyidagilarga bo'linishi mumkin: standart, umumiy, har xil, maxsus g'isht, qo'shimcha ravishda, pishirish usuli bo'yicha refrakterlar, foydalanishga ko'ra, qurilish xususiyatlariga ko'ra, boshqa tasniflar mavjud.
