Yog vim li cas vim li cas refractory ores tsis tuaj yeem siv ncaj qha los tsimrefractory bricksFeem ntau suav nrog cov hauv qab no:
1. Muaj pes tsawg leeg thiab purity
Tsis sib xws: Cov tshuaj muaj pes tsawg leeg ntawm ntuj refractory ores feem ntau tsis sib xws, thiab kev siv ncaj qha yuav ua rau kev ua haujlwm tsis ruaj khov ntawm refractories cib.
Cov ntsiab lus siab impurity: Ores feem ntau muaj cov impurities siab, xws li hlau, alkali hlau oxides, thiab lwm yam. Cov impurities no yuav txo qhov kev ua tau zoo ntawm refractory thiab tshuaj stability ntawm refractory firebricks.
2. Lub cev qauv
Qhov loj me me tsis haum: Qhov loj me me ntawm cov khoom siv ntuj tsim tsis sib xws thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob refractory.
Cov qauv xoob los yog tuab dhau: Cov qauv ntawm lub cev ntawm cov pob zeb ntuj tuaj yeem xoob dhau los yog tuab heev, thiab kev siv ncaj qha yuav cuam tshuam rau sintering thiab lub zog ntawm refractories bricks.
3. Pretreatment yuav tsum
Calcination yuav tsum tau: Ntau refractory ores yuav tsum tau calcined kom tshem tawm cov dej siv lead ua thiab cov organic impurities, thiab ua kom lawv muaj pes tsawg leeg thiab txhim kho cov ntxhia theem qauv.
Kev sib tsoo thiab kev tshuaj ntsuam xyuas yuav tsum tau: Cov ore yuav tsum tau ua hauv av thiab tshuaj xyuas kom tau txais cov khoom me me uas haum rau cov khoom siv refractory cib.
4. Sintering thiab binder yuav tsum tau
Sintering kev ua tau zoo sib txawv: sintering kev ua tau zoo ntawm cov ores sib txawv heev, thiab kev siv ncaj qha yuav tsis tsim cov pob zeb refractory ntom.
Yuav tsum tau ntxiv cov binders: txhawm rau txhim kho lub zog thiab tawv ntawm refractory hluav taws cib, ib qho tsim nyog ntawm cov binders, xws li refractory av nkos los yog tshuaj binders, yuav tsum tau ntxiv thaum lub sij hawm tsim khoom.
5. Cov qauv thiab cov txheej txheem yuav tsum tau ua
Cov mis mos: Refractory hluav taws cib ntau lawm yuav tsum muaj cov qauv raw khoom sib txawv raws li kev siv tshwj xeeb kom tau raws li qhov yuav tsum tau muaj ntawm refractoriness, lub zog, thermal shock stability, thiab lwm yam.
Cov txheej txheem ntau lawm: Cov txheej txheem ntau lawm ntawm cov hluav taws kub refractory muaj xws li ntau cov kauj ruam xws li kev sib tov, molding, ziab thiab tua. Txhua kauj ruam yuav tsum tau tswj nruj me ntsis. Nws yog qhov nyuaj kom ua tau raws li cov txheej txheem no los ntawm kev siv cov ore ncaj qha.
Cov kauj ruam tshwj xeeb thiab cov txheej txheem
Ore beneficiation thiab ua:
Ore yuav tsum tau crushed, hauv av thiab tshuaj ntsuam kom tshem tawm impurities thiab kho cov particle loj tis.
Rau qee qhov ore, calcination yuav tsum tau tshem tawm cov khoom tsis zoo thiab txhim kho lub cev.
Kev sib xyaw thiab cov qauv kev hloov kho: Raws li kev ua tau zoo ntawm cov pob zeb refractory, ntau hom refractory cov ntaub ntawv thiab cov khoom siv ntxiv yog sib xyaw, thiab cov qauv raug hloov kho kom zoo dua qhov refractoriness, lub zog thiab thermal shock stability. Ntxiv cov ntaub ntawv tsim nyog, xws li cov av nkos refractory, tshuaj binders, thiab lwm yam, txhawm rau txhim kho lub zog sib txuas ntawm lub cev cib. Moulding thiab ziab: Cov khoom sib xyaw ua ke yog molded, thiab ntau txoj hauv kev suav nrog nias, extrusion thiab grouting. Cov bricks molded yuav tsum tau qhuav kom tshem tawm cov dej noo thiab tiv thaiv kev tawg lossis deformation thaum lub sijhawm tua. Kev tua hluav taws thiab sintering: Cov cib qhuav yuav tsum raug rho tawm haujlwm hauv qhov kub kub, thiab qhov kub-kub sintering ua rau cov qauv cib ntom ntom thiab lub zog nce. Cov txheej txheem tua hluav taws yuav tsum tau tswj xyuas qhov kub thiab txias kom nruj kom ntseeg tau tias qhov zoo thiab kev ua haujlwm ntawm cov hluav taws kub refractory cib. Muaj ntau qhov kev sib tw hauv kev siv cov khoom siv ntuj tsim los tsim cov refractories cib, nrog rau cov tsis sib xws, cov ntsiab lus siab impurity, thiab tsis tsim nyog particle loj tis. Los ntawm cov kauj ruam ntawm kev hnav khaub ncaws ore, pretreatment, kev hloov pauv mis, molding thiab firing, qhov zoo thiab kev ua tau zoo ntawm cov ntaub ntawv refractory tuaj yeem txhim kho kom tau raws li qhov xav tau ntawm cov ntawv thov sib txawv.
