1. Micropowder
SiO2 micropowder muaj txiaj ntsig zoo rau kev txhawb nqa sintering dua li Al2O3 micropowder. Nrog rau qhov nce ntawm SiO2 micro hmoov ntxiv, chav tsev kub flexural zog thiab compressive zog tom qab kev kho cua sov ntawm 1100 degree thiab 1400 degree tau txhim kho. Qhov no yog vim hais tias piv rau Al2O3 micropowder, SiO2 micropowder tsim los ntawm vapor deposition muaj ib tug me me particle loj, loj dua qhov chaw, thiab ntau dua kev ua.
2. Binder
Muaj ntau hom aluminate cement binders. Thaum ntau yam sib txawv, qhov ua tau zoo ntawm cov cement refractory castables tsawg kuj sib txawv.
3. Dej txo tus neeg sawv cev
Tus neeg saib xyuas dej yog ib yam khoom uas tuaj yeem txo cov dej siv hauv kev sib xyaw ua ke, tseem hu ua tus neeg saib xyuas nag lossis daus, dispersant, lossis plasticizer, thaum tswj cov nqi qis ntawm cov castable. Cov dej txo cov neeg ua haujlwm ua lub luag haujlwm tseem ceeb hauv cov castables refractory, tshwj xeeb tshaj yog nyob rau hauv qis cement thiab ultra-low cement refractory castables.
4. Aggregates thiab lawv muaj pes tsawg leeg
Thaum npaj cov cement series refractory castables tsawg, cov refractory aggregate feem ntau siv ntau qib particle grading es tsis txhob siv cov khoom sib koom ua ke tom qab crushing.
5. Cov dej ntxiv
Zoo li lwm yam refractory castables, cov dej noj ntawm cov cement series refractory castables kuj tau lav rau ntawm qhov chaw ntawm kev ua haujlwm ntawm kev sib tov. Kev siv dej tsawg dua, qhov zoo dua. Nyob rau hauv txoj kev no, tom qab molding lub cev ntawm cov khoom casting hardens, muaj tsawg pores, tag nrho cov porosity txo, lub microstructure yog ntom, linear hloov tom qab tua me me, thiab lub zog nce.
