Alkaline refractory cov ntaub ntawv tsuas yog xa mus rau cov ntaub ntawv refractory tsuas yog tsim los ntawm magnesium oxide thiab calcium oxide, uas muaj zog corrosion kuj rau alkaline slag. Xws li magnesia bricks, magnesia aluminium cib, magnesia chromium cib, dolomite cib, thiab lwm yam (saib magnesia cib).
Magnesia bricks feem ntau siv. Magnesium bricks uas muaj ntau tshaj 80% mus rau 85% magnesium oxide muaj kev tiv thaiv zoo rau alkaline slag thiab hlau slag, thiab lawv cov hluav taws kub tsis kam yog siab dua cov av nplaum cib thiab silica cib. Feem ntau siv nyob rau hauv qhib lub qhov cub, oxygen tshuab converters, hluav taws xob furnaces, non-ferrous hlau smelting khoom, thiab ib co high-temperature khoom.
Cov yam ntxwv ntawm cov khoom siv alkaline refractory
Inorganic non-metallic cov ntaub ntawv uas muaj hluav taws kub siab tshaj 1580 degree. Hluav taws kub tsis kam yog hais txog qhov kub ntawm qhov kub ntawm qhov kub ntawm qhov uas cov qauv conical ntawm cov khoom siv refractory tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj softening thiab melting nyob rau hauv tsis muaj load. Cov ntaub ntawv refractory thiab high-temperature technology tau tshwm sim ua ke, kwv yees li rov qab mus rau lub hnub nyoog Bronze. Thaum lub sij hawm Eastern Han Dynasty nyob rau hauv Tuam Tshoj, cov ntaub ntawv av nplaum refractory twb tau siv los ua cov ntaub ntawv kiln thiab caskets rau tua plooj (porcelain). Thaum pib ntawm lub xyoo pua 20th, cov ntaub ntawv refractory tau tsim los ntawm cov khoom siv purity siab, siab ceev, thiab ultra-siab kub cov khoom, thaum tib lub sij hawm, cov ntaub ntawv amorphous refractory thiab refractory fibers tau tshwm sim uas tsis tas yuav tua thiab tsis muaj zog noj. Nyob rau lub sijhawm tam sim no, nrog kev txhim kho ntawm atomic zog thev naus laus zis, thev naus laus zis thev naus laus zis, thiab thev naus laus zis thev naus laus zis, cov ntaub ntawv refractory nrog cov khoom zoo heev xws li kub tsis kam, corrosion resistance, thermal vibration resistance, thiab yaig kuj tau siv.
