Cov Txheej Txheem Ntau Lawm Ntawm Tabular Alumina

Covtxheej txheem ntawm tabular alumina

Kev loj hlob ntawmtabular aluminatau coj kev txhim kho tseem ceeb hauv kev ua tau zoo thiab kev tsim khoom ntawm cov txheej txheem steelmaking. Nws zoo heev thermal poob siab tsis kam thiab qis coefficient ntawm thermal expansion kom ruaj khov ntawm cov txheej txheem steelmaking, thiab nws cov nqi qis ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm siab refractories.

Kev tsim cov txheej txheem ntawm tabular alumina suav nrog ntau theem, suav nrog:

1. Crushing thiab sib tsoo: Cov khoom siv raw xws li bauxite, limestone, thiab hlau oxide raug crushed thiab hauv av rau hauv cov hmoov zoo.
2. Ci: Cov hmoov yog ci ntawm qhov kub thiab txias kom tshem tawm cov dej noo thiab tsim kom muaj lub cev ntom ntom.
3. Crystallization: Lub cev sintered yog crystallized los ntawm txias rau qhov kub ntawm 2000-2200 degree .
4. Kev ziab thiab sib tsoo: Lub cev crystallized yog qhuav thiab hauv av rau hauv cov hmoov zoo.
5. Fertilization: Cov hmoov yog tom qab ntawd tov nrog cov chiv xws li magnesium oxide thiab aluminium oxide los kho nws cov khoom thiab tawm los ntawm cov khoom kawg.

Tabular aluminaFeem ntau yog siv rau hauv cov txheej txheem steelmaking, qhov twg nws yog siv los ua cov khoom siv refractory rau hauv ob sab phlu, ladle ru tsev, tawg lub thawv, molding nruas, ladle tundish, thiab lwm yam steelmaking khoom. Nws zoo heev thermal poob siab tsis kam thiab qis coefficient ntawm thermal expansion ua rau nws zoo tagnrho rau siv nyob rau hauv high-temperature ib puag ncig, thaum nws siab purity thiab tsis tshua muaj nqi xyuas kom meej nws cov kev sib tw nyob rau hauv lub lag luam.

Hauv kev xaus, tabular alumina yog cov khoom siv hluav taws xob ua haujlwm siab uas tau siv dav hauv kev lag luam steel rau ntau tshaj 40 xyoo. Nws zoo heev thermal poob siab tsis kam, qis coefficient ntawm thermal expansion, thiab tus nqi qis ua rau nws xaiv zoo tshaj plaws rau cov ntaub ntawv refractory. Kev tsim cov txheej txheem ntawm tabular alumina yog complex, tab sis nws cov zoo yog tsim, thiab nws tau raug lees paub tias yog ib qho tseem ceeb ntawm cov khoom siv rau kev loj hlob ntawm niaj hnub steel kev lag luam.
