3. Kev faib cov refractories raws li lawv cov khoom tseem ceeb
Qhov thiaj li -hu ua cov khoom tseem ceeb yog thawj theem thiab theem ob, cov ntsiab lus ntawm kwv yees li 90% ntawm tag nrho cov tshuaj muaj pes tsawg leeg.
Niaj hnubrefractorytechnology txhim kho ntau thiab ntau cov khoom xyaw, yog li qhov tshwm sim ntawm lub thib ob theem, lub thib peb theem muaj pes tsawg leeg, kho lub thib ob theem, lub thib peb theem muaj pes tsawg leeg muaj peev xwm tsim ib tug tshiab technology, nyob rau hauv cov tshuaj muaj pes tsawg leeg tshaj thawj theem ntawm cov kev txwv kev faib, yog cov feem ntau siv ntawm ib tug faib txoj kev.
(1) silicon-aluminium series khoom: rau silicon-aluminium series ntawm cov ntaub ntawv, lub ntsiab tivthaiv yog SiO2, Al2O3, nws muaj xws li av nplaum cib, siab alumina cib, silica nepheline, bluestone, rhodochrosite, mullite cib thiab lwm yam khoom.
(2) magnesium-chromium series khoom: magnesium-chromium series nyob rau hauv lub ntsiab Cheebtsam yog MgO, Cr2O3, magnesite rau thawj theem, magnesium-chromium spinel rau lub thib ob theem, belongs rau cov series ntawm cov khoom yog magnesium-chromium cib thiab chromium-magnesium cib.
(3) magnesium aluminium series khoom: cov khoom tseem ceeb yog MgO, Al2O3, raws li lawv tsim MgO.Al2O3, magnesium-chromium series cov khoom muaj magnesium cov ntaub ntawv.
(4) magnesium calcium series khoom: lub ntsiab tivthaiv yog MgO, CaO. lawv muaj cov ntsiab lus melting siab heev, yog cov khoom siv magnesium tseem ceeb.
(5) magnesium -silicon series khoom: magnesium xuab zeb system lub ntsiab tivthaiv yog SiO2, thaum C / S<5, SiO2 and MgO to generate MgO.Al2O3 (magnesium olivine), from the perspective of the micro-mineral composition, the main products of the pure aluminum series of magnesium-aluminum bricks, square magnesia spinel bricks, corundum spinel bricks, the aluminum in the indeterminate material - spinel castables also belong to magnesium-aluminum series products.
