Cov khoom siv refractory thiab lwm yam khoom siv

Refractory txheej
Cov khoom siv rau refractory cib hauv ob sab phlu. Raws li kev siv sib txawv thiab kev tsim kho, cov txheej txheem refractory tuaj yeem npaj ua cov av nkos lossis av nkos. Cov binders siv sib txawv nyob ntawm seb cov khoom siv, xws li alkaline coatings phosphate, polyphosphate, thiab magnesium sulfate siv rau hauv kev npaj ntawm nruam casting tundish; Av nplaum, aluminium dihydrogen phosphate, aluminium chromium phosphate, iav dej, thiab lwm yam yog siv los npaj cov txheej txheem alumina siab. Txhawm rau txhim kho qhov siv tau ntawm cov txheej txheem, cov yas yas thiab lwm yam khoom siv feem ntau yog ntxiv. Coatings feem ntau yog siv los tiv thaiv cov txheej txheem rau ntau yam khoom siv thermal hauv ob sab phlu, lossis kho cov kev puas tsuaj hauv zos rau cov pob zeb cib.
Ramming khoom
Cov khoom siv xoob refractory uas tsis tshua muaj siab lossis tsis muaj plasticity. Cov ntaub ntawv muaj xws li silicon, av nplaum, siab alumina, corundum, zircon, silicon carbide, carbon, magnesium, thiab lwm yam. dej-soluble dextrin, carboxymethyl cellulose, lignin, sulfonates, thiab polyvinyl cawv; Paraffin wax, asphalt, tar, phenolic resin, random polypropylene, thiab lwm yam uas tiv taus dej thiab muaj cov khoom siv thermoplastic.
Cov khoom siv ramming txais yuav raug yuam ramming tsim, nrog tsawg porosity thiab siab ceev. Yog li ntawd, nyob rau hauv cov ntaub ntawv amorphous refractory, ramming khoom yog tshwj xeeb tshaj yog haum rau hauv ob sab phlu smelting furnaces thiab ntau lub thawv uas muaj high-temperature hlau yaj. Xws li qhib hearth thiab hluav taws xob rauv txaj, ntau yam induction rauv linings, moj tej tawg rauv tapping raws, steel nruas, thiab lwm yam.
Cov khoom siv projection
Ib hom semi qhuav av siv rau hauv ob sab phlu nrog lub projector. Feem ntau yog siv los tsim cov kab hauv ob sab hauv ntawm ib lub nruas steel. Cov ntaub ntawv muaj xws li siliceous, paraffin, av nplaum, siab alumina, thiab zircon. Cov khoom siv feem ntau yog cov khoom siv silicon siab thiab cov khoom siv aluminium siab.
Qhuav mix
Cov ntaub ntawv sib xyaw qhuav, tseem hu ua cov khoom vibrating qhuav lossis cov ntaub ntawv qhuav. Cov ntaub ntawv tsis zoo li refractory tsim siv kev co lossis ramming hauv lub xeev qhuav. Cov khoom siv no feem ntau muaj qee cov ntaub ntawv ib ntus, uas tau muab tshem tawm ntawm pwm tom qab ci.
