Kev ua tau zoo thiab kev tsim khoom ntawm Magnesia Chrome Bricks
Magnesia chrome cib muaj tsawg impurities. Tom qab kub-kub thiab ultra-high-temperature firing, lub iav theem yog concentrated nyob rau hauv lub triangular cheeb tsam ntawm lub crystal theem, thiab lub crystal theem thiab lub crystal theem yog ncaj qha ua ke. Hom magnesia-chrome cib no muaj qhov porosity tsawg, siab compressive zog, muaj zog hnav tsis kam, zoo corrosion kuj, thermal shock kuj, thiab spalling kuj.
Thaum nws los txog rau cov txheej txheem ntawm kev sib txuas ncaj qha magnesite chrome cib, thawj zaug pib los ntawm kev sib txuas ncaj qha magnesite chrome cib, nws hais txog cov khoom siv hluav taws xob uas ncaj qha ua ke nrog periclase thiab magnesite chrome spinel ua lub ntsiab siv lead ua theem. Lub cib yog ua los ntawm high-purity sintered magnesia thiab chromite nrog sio2 tsawg dua 2% raws li raw cov ntaub ntawv thiab sintered nyob rau hauv high kub. Direct bonded magnesia chrome bricks yog cov khoom tsim los ntawm high-purity los yog sub-high-purity sintered los yog fused magnesia thiab chrome concentrate. Direct bonding yog hais txog ib daim ntawv cog lus uas tsim los ntawm kev sib cuag ncaj qha ntawm cov hmoov nplej-theem. Lub cib yog ua los ntawm high-purity sintered magnesia thiab chrome concentrate nrog sio2<2% as raw materials and is sintered at high temperatures. The degree of direct bonding of the product increases with the decrease of sio2 content and the increase of firing temperature.
Thaum tsim cov magnesia chrome cib, chrome ore uas tsis tshua muaj sio2 cov ntsiab lus yuav tsum raug xaiv kom ntau li ntau tau, vim tias cov ntsiab lus tsis tshua muaj sio2 muaj txiaj ntsig los txhim kho cov kev ua haujlwm kub ntawm cov cib refractory. Los ntawm kev sib piv cov khoom ntawm ntau yam magnesia-chrome cib, nws pom tau hais tias qhov load-softening kub ntawm magnesia chrome cib tsim los ntawm kev xaiv high-purity sio2 (cov ntsiab lus tsawg) chrome ore yog siab. Tau kawg, magnesia-chrome cib nrog cov ntsiab lus sio2 tsawg kuj yuav tsum tau raug rho tawm haujlwm ntawm qhov kub thiab txias. Raws li ntau txoj haujlwm tshawb fawb tau taw qhia. Txawm hais tias tsis muaj qhov pom tseeb sib faib kab ntawm silicate-bonded (ceramic-bonded) magnesia-chrome cib thiab ncaj qha-bonded magnesia-chrome cib, muaj tiag nyob rau hauv magnesia-chrome cib raug rho tawm haujlwm hauv qab 1500 degree c. Tsuas yog thaum qhov hluav taws kub kub tshaj 1550 degree c, lawv cov kev sib txuas ncaj qha yuav nce.
Txij li tam sim no magnesia-chrome cib tag nrho raug rho tawm haujlwm siab tshaj 1500 degree c, lawv tsuas yog sib txawv ntawm qib ntawm kev sib txuas ncaj qha. Qhov no qhia tau hais tias thawj qhov xwm txheej rau kev tsim cov khoom sib txuas ncaj qha magnesia-chrome refractory bricks yog firing ntawm qhov kub thiab txias. Piv txwv li, magnesia-chrome cib uas muaj 1.5% sio2 raug rho tawm haujlwm ntawm 1800 degree c, piv nrog rau lwm cov magnesia-chrome cib, vim tias qhov sib txuas ncaj qha ntawm theem siab refractory nce. Txawm li cas los xij, qhov kub thiab txias heev yuav ua rau deformation thiab upside-down ntawm xws li magnesia-chrome cib thiab ua rau kom cov khib nyiab refractory cib.
Txhawm rau txo cov khoom pov tseg uas tshwm sim los ntawm kev tua hluav taws deformation, cov kev ntsuas hauv cov txheej txheem thev naus laus zis yog txo cov ntsiab lus sio2 hauv cov khoom xyaw (tshwj xeeb yog cov ntsiab lus sio2 hauv cov chrome ore). Tus nqi ntawm kev sib txuas ncaj qha hauv magnesia-chrome cib nce ntxiv nrog rau qhov txo qis hauv sio2 cov ntsiab lus. Qhov no yog vim hais tias thaum cov ntsiab lus sio2 raug txo, cov txheej silicate hauv cov khoom yog hloov los ntawm kev sib xyaw ncaj qha ntawm cov muaju ntawm cov qib siab refractory.
