Kev piav qhia txog Alumina Castable Siab
Cov khoom siv alumina siab yog ib hom khoom siv refractory uas siv cov khoom siv alumina siab ua cov khoom sib xyaw thiab cov hmoov thiab tom qab ntawd ntxiv nrog cov neeg sawv cev khi. Cov khoom siv refractory aluminium siab muaj lub zog kho tshuab siab, tiv taus thermal poob siab zoo, tiv taus corrosion zoo. Cov khoom siv refractory alumina siab yog cov khoom siv refractory amorphous nrog kev txav mus los siab, cov khoom siv refractory alumina siab yog ua los ntawm cov khoom sib xyaw refractory, hmoov, binder, additives, dej, lossis lwm yam khoom siv kua. Cov khoom siv alumina siab tuaj yeem siv nrog txoj kev molding ntawm qhov chaw casting, vibrating lossis tamping, kuj tseem tuaj yeem ua preform siv thiab tuaj yeem siv nrog txoj kev casting ntawm kev tsim kho tab sis yuav tsum tau hardened yam tsis muaj cua sov.

Tsib kauj ruam ntawm High Alumina Castable
Xaiv cov khoom siv raw ntawm cov khoom siv aluminium casting siab raws li cov mis.
Xam qhov kev hloov pauv thiab qhov ntau npaum li cas ntawm cov khoom sib xyaw, hmoov, cov khoom sib txuas thiab cov khoom ntxiv raws li cov mis ntawm cov khoom siv raw, thiab tswj hwm cov hmoov sib xyaw kom nruj.
Muab cov hmoov sib xyaw thiab cov hmoov uas tau muab tso rau hauv lub tshuab sib tov ib qho tom qab ib qho, thiab tom qab ntawd ncuav cov hmoov rau hauv cov hmoov sib xyaw thiab do rau 8-10 feeb.
Muab cov khoom siv txhuas siab uas tau sib xyaw rau hauv lub hnab ton, nruab nrog cov khoom ntxiv thiab cov ntawv khi, thiab tom qab ntawd pob.
Cov khoom siv txhuas uas ntim khoom ntau yuav tsum khaws cia rau hauv lub tsev rau khoom, thiab hnub tim yuav tsum tau cim thiab tsis muaj dej noo thiab tsis ntub dej.
Cov txiaj ntsig ntawm High Alumina Castable
- Kev ua kom tsis muaj zog siab, Kev ua kom tsis muaj zog siab nyob rau hauv qhov hnyav,
- Qhov ceev ceev, qhov porosity tsawg,
- Zoo slag tsis kam thiab corrosion tsis kam,
- Muaj zog thiab hnav tsis kam,
- Zoo tiv taus kev ua tau zoo ntawm cov flake,
- Kev ruaj khov zoo ntawm thermal shock,
- Kev tiv thaiv kev txhuam,
- Lub zog kub zoo.

Daim Ntawv Thov ntawm High Alumina Castable
Cov castable alumina siab yog tsim tawm tom qab tsim nyob rau hauv qhov kub siab hauv rotary thiab zom ua hmoov. cov khoom no yog rau kev ua cov castables refractory zoo, uas yog ib qho cuab yeej tsis siv tau siv rau hauv cov chaw kub siab hauv kev lag luam xws li metallurgy, cov khoom siv hauv tsev, tshuaj lom neeg, thiab cov nroj tsuag hluav taws xob. Tsis tas li ntawd, cov castables alumina siab kuj siv tau rau hauv cov chaw hauv qab no.
- Sab hauv ntawm lub cub tawg rotary,
- Thermal converter sab hauv,
- Kev lag luam hlau,
- Kev lag luam tshuaj lom neeg,
- Kev lag luam tsim kho.
