Khoom Description

Refractory magnesia chromium cib yog cov khoom siv siab - zoo, siab - cov khoom siv ua haujlwm feem ntau yog ua los ntawm magnesium oxide thiab chromium oxide. Nws muaj kev tiv thaiv hluav taws zoo heev thiab tuaj yeem tiv taus cov tshuaj lom neeg, acid thiab alkali corrosion thiab txhua yam cuam tshuam hauv qhov kub thiab txias. Vim tias cov khoom tshwj xeeb ntawm cov khoom siv no, nws tau siv dav hauv ntau lub lag luam xws li steel, machinery manufacturing, chemical industry, metallurgy thiab light industry.

Qhov ceev ntawm refractory magnesia-chrome bricks feem ntau yog nyob nruab nrab ntawm 2.9-3.1g/cm³, uas yog lub teeb. Nws lub zog flexural yog siab heev, feem ntau ntawm 50-70MPa. Cov khoom siv muaj zog heev thaum tshav kub kub tsis kam thiab tuaj yeem siv rau hauv qhov kub thiab txias ib puag ncig ntev. Qhov siab tshaj plaws ua haujlwm kub tuaj yeem ncav cuag 1800 degree.

Cov khoom tseem ceeb ntawm cov khoom siv no yog magnesium oxide thiab chromium oxide, nrog rau lwm cov khoom siv pabcuam. Nws muaj cov ntsiab lus oxide siab thiab tuaj yeem tiv taus tshuaj tua kab mob. Cov ntsiab lus ntawm txhua yam tshuaj muaj qee yam yuav tsum tau ua. Piv txwv li, cov ntsiab lus ntawm magnesium oxide feem ntau yog siab dua 85%, thiab cov ntsiab lus ntawm chromium oxide feem ntau yog 10-15%.
