High Alumina Hluav Taws Cib Cov Khoom
Refractoriness
High Alumina Hluav Taws Cib Cov Khoom Siv yog cov qib siab alumina-silicate refractory. Lawv cov refractoriness yuav nce nrog qhov nce ntawm Al2O3 cov ntsiab lus, uas feem ntau tsis qis dua 1750 ~ 1790 degree. Thaum Al2O3 cov ntsiab lus nce mus txog 95%, nws yog corundum cib uas tuaj yeem tiv taus siab refractoriness ntawm 1900 ~ 2000 degree.
Refractoriness nyob rau hauv Load
High Alumina Hluav Taws Cib Cov Khoom 'refractoriness nyob rau hauv load yuav txo nrog qhov nce ntawm SiO2 cov ntsiab lus thiab alkali hlau oxide cov ntsiab lus, uas yog siab tshaj fireclay bricks 'refractoriness nyob rau hauv load ntawm 1420 ~ 1530 degree. Corundum bricks 'refractoriness nyob rau hauv load ncav cuag 1600 degree.
Slag Resistance
Raws li lub siab alumina hluav taws cib muaj ntau qhov nruab nrab Al2O3 cov ntsiab lus, cov khoom siv refractory no muaj zog alkali rauv slag yaig tsis kam.
Thermal Shock Stability
Hauv cov khoom siv hluav taws kub alumina siab, muaj ob hom crystals ntawm corundum thiab mullite tawm. Raws li corundum lub thermal expansion coefficient yog siab tshaj mullite's. Thaum qhov kub hloov pauv tau tshwm sim rau cov cib refractory, qhov sib txawv thermal expansion ua rau muaj kev ntxhov siab. High alumina hluav taws cib khoom ' thermal shock stability yog phem tshaj fireclay bricks khoom'.
Reheating Linear Hloov
Yog hais tias qhov hluav taws kub kub thiab lub sij hawm ntawm high alumina bricks khoom yog txaus, lub ntim yog ruaj khov thiab reheating linear hloov yog tsawg. Los yog, recrystallization yuav ua rau cov kab tom qab cog lus ntawm fireclay cib.
