2022 tshiab chrome corundum cib

Khoom zoo: tsawg porosity, kev kub ceev, siab zog, zoo siab kub coj kuj, zoo kuj huab txias thiab huab cua kub, zoo slag tsis kam, thiab zoo durability.

khoom piav qhia

Chromium corundum refractory cib yog sib xyaw los ntawm ntshiab Al2O3 thiab Cr2O3 ua cov khoom siv tseem ceeb. Piv nrog cov cib corundum ntshiab, nws muaj cov khoom zoo dua, xws li kev rov ua dua tshiab, ua kom lub cev deformation kub hauv qhov hnyav, ua kom lub zog khov kho, ua kom sov siab dua, ua kom kub siab ruaj khov thiab tiv taus slag tiv taus.

Chrome corundum cib yog corundum refractory cib uas muaj Cr2O3. Thaum kub siab, Cr2O3 thiab Al2O3 tsim cov khoom sib txuas tas mus li. Yog li ntawd, kev ua haujlwm kub ntawm chromium corundum cib yog qhov zoo dua li cov cib ntshiab corundum. Cov chromium corundum cib siv hauv cov cua sov ua kom sov ntawm kev lag luam petrochemical yuav tsum yog cov uas tsis muaj silicon, cov hlau qis, cov alkali tsawg, kev ua kom huv siab, tab sis kuj muaj qhov ntom ntom ntom ntom thiab muaj zog. Chrome corundum cib tau siv dav, thiab cov ntsiab lus ntawm Cr2O3 feem ntau yog nyob ntawm thaj tsam ntawm 9% txog 15%.

chrome corundum cib kuj tseem hu ua siab hnav-tiv taus chromium corundum tapping channel cib. Nws yog cov khoom lag luam siab kawg tau txhawb nqa hauv kev ua lag luam hauv xyoo tas los no. Nws yog tsim los ntawm cov ntshiab alumina Al2O3 thiab chromium oxide Cr2O3 ua cov khoom siv tseem ceeb. Piv nrog cov cib corundum ntshiab, nws muaj cov khoom zoo dua, xws li rov ua dua tshiab, thauj qhov muag muag kub, ua kom lub zog muaj zog, ua kom sov siab dua, ua kom kub siab ruaj khov thiab ua rau xeb tiv taus. Chrome corundum cib yog ib hom khoom siv qib siab ua kom tsis muaj zog, thiab nws lub neej ua haujlwm tuaj yeem ncav cuag 10 txog 18 lub hlis tom qab ntau tus neeg siv zeb zeb siv.

Kev xyaum tau qhia pom tias daim ntawv thov siab hnav-tiv taus chromium corundum tapping channel cib nyob rau hauv tapping channel ntawm lub rhaub cua sov rau cua sov loj-seem billets, kev sib txhuam siab ib cheeb tsam hauv cheeb tsam thiab cov zis siab, tsis tsuas yog tuaj yeem txuas ntxiv qhov kev pab cuam lub neej ntawm tapping channel thiab txo cov cua sov kaw Lub Sijhawm, nce kev tsim khoom, txo kev siv hluav taws xob thiab kev saib xyuas tus nqi, thiab txo tus naj npawb ntawm cov cua txias sai thiab cua sov tshwm sim los ntawm kev kaw lub cub tawg rau kev saib xyuas, kom lub neej nyob rau hauv lub cub tawg tau zoo dua, thiab pom tseeb cov txiaj ntsig kev lag luam tuaj yeem ua tiav.
