Tsawg chromium magnesia chrome cib rau cement kilns thiab ncaj qha sib raug zoo magnesia chrome cib

Magnesia chrome cib yog cov khoom siv hluav taws xob nrog magnesium oxide (MgO) thiab chromium trioxide (Cr2O3) ua lub hauv paus tseem ceeb, thiab periclase thiab spinel ua cov khoom tseem ceeb. Hom cib no muaj qhov ua kom rov zoo dua qub, ua kom muaj zog kub, muaj zog tiv taus alkaline slag yaig, zoo heev thermal stability, thiab qee qhov hloov pauv rau acid slag. Cov ntaub ntawv tseem ceeb rau kev ua magnesia-chrome cib yog sintered magnesia thiab chromite. Lub purity ntawm magnesia raw cov ntaub ntawv yuav tsum yog kom ntau li ntau tau. Cov tseev kom muaj rau cov tshuaj lom neeg muaj pes tsawg leeg ntawm chromite yog: Cr2O3: 30 ~ 45%, CaO: ≤1.0 ~ 1.5%.

Magnesium chrome cib feem ntau yog siv hauv kev lag luam hlau, xws li kev tsim kho qhib lub qhov cub hluav taws kub saum toj, hluav taws xob ua hluav taws xob sab saum toj, lub tshuab ua kom sov ua kom sov thiab ntau yam uas tsis yog hlau ua rauv taws. Qhov kub thiab txias ib feem ntawm cov cua sov phab ntsa ntawm lub tshuab hluav taws xob ultra-high fais fab yog ua los ntawm cov fused-cam khwb cia magnesia-chrome cib, thaj chaw uas muaj kev yaig ntawm lub tshuab ua kom sov sab nraum lub cub tawg yog ua los ntawm cov khoom siv hluavtaws, thiab thaj chaw yaig ntawm cov hlau uas tsis yog-ferrous flash smelting rauv yog ua los ntawm fused-cam khwb cia magnesia-chrome cib thiab cov khoom siv hluavtaws. Ua los ntawm magnesia chrome bricks. Ib qho ntxiv, magnesia-chrome cib kuj tseem siv nyob rau hauv qhov chaw hlawv ntawm cov cement rotary kilns thiab tsim cov iav kilns.

Lub cev thiab tshuaj muaj zog ntawm qis chromium magnesia chrome cib thiab sib txuas ncaj qha magnesia chrome cib siv hauv cov cement kilns yog raws li hauv qab no:

Muaj feem xyuam nrog kev sib xyaw thiab kev ua tau zoo ntawm ob hom cib, kev lag luam sib txawv thiab cov ntsiab lus yuav tsum tau ua tib zoo saib xyuas hauv kev coj ua hauv kev siv cov cement kilns.

1. Cib txheej

Ncaj nraim ua ke nrog magnesia-chrome cib qis dua 1500, kab hloov pauv tuaj yeem ncav cuag +0.2% -0.8%. Muaj cov hlau hlau lossis cov av nkos hauv cov av hauv lub voj voos kom nqus tau cov khoom siv sib koom ua ke no, yog li cov txheej txheem masonry huv si tsis muaj daim hlau hlau lossis av av tsis tuaj yeem siv tau. , Thiab qis chromium magnesia chrome cib tau muab nrog lub hauv ncoo los xij, tom kawg nrog daim ntawv tuab ntawm 2 hli

2. Ci ci

Kev sib txuas ncaj qha magnesia-chrome cib muaj kev nkag siab ntau ntxiv rau kev nyuaj siab sab hauv ntawm cov cib txheej ua los ntawm cua sov thiab ellipticity ntawm lub cev kiln, yog li yuav tsum tau tswj nruj.
Kev sib txuas ncaj qha magnesia-chrome cib muaj ntau cov chromium, muaj kev tiv thaiv qis rau alkali corrosion hauv qhov chaw oxidizing, thiab cov ntawv cog lus sib txuas ntawm cov qib chromium uas muaj theem tau raug puas tsuaj. Cov cib tau yooj yim rau kev puas tsuaj thiab ua rau muaj kuab paug rau ib puag ncig.

3. Tiv thaiv kom txo tau huab cua

Cov tshuaj tiv thaiv tib yam tshwm sim hauv ob hom cib nyob rau hauv qhov txo qis huab cua, uas rhuav tshem txoj kev sib khi thiab thaum kawg ua rau cov cib puas. Kev sib txuas ncaj qha ntawm cov cib magnesia-chrome yuav cuam tshuam ntau dua.

4. Cuam tshuam ntawm kev tsim cov tawv nqaij kiln

Cov txheej txheem nplua nuj hauv C4AF yuav tsim los ntawm cov qib qis-chromium thiab cov hlau siab magnesia-chrome cib txheej thiab cov clinker, yog li cov tawv nqaij ua haujlwm tau zoo dua. Qhov ua tau zoo ntawm daim tawv nqaij ua kom sib xyaw ua ke nrog cov magnesia-chrome cib sib txawv nrog cov muaj pes tsawg leeg ntawm cov cib. Ib zaug ntawm daim tawv nqaij ntawm lub cev yog ib txwm Thaum tsim thiab kho tau zoo, qhov kub ntawm cov cib saum hauv qab daim tawv nqaij kiln poob qis heev, thiab nws tsis yog ib qho tseem ceeb heev rau ncaj qha ua ke qhov zoo ntawm cov cua sov siab zog ntawm magnesia chrome cib.
Tam sim no tau tawm los ntau qhov qis chrome magnesia-chrome cib, chrome-free tshwj xeeb cib, muaj peev xwm ntau lawm txog li 6000-10000T / h ntawm PC kiln, qhov kub thiab txias tsis kam tiv taus yog qhov tseem ceeb heev, lawv tsim cov lus qhia sib xws ua ke nrog siab purity chromium-free tshwj xeeb magnesium feem ntau yog siv hauv thaj tsam hloov pauv ntawm cov cement kilns.
