Kev siv cov silicon carbide

Silicon carbide tseem hu ua xuab zeb kub lossis xuab zeb refractory. Silicon carbide yog ua los ntawm xuab zeb quartz, roj av coke (lossis thee coke), ntoo chips (kev tsim cov silicon carbide ntsuab yuav tsum ntxiv ntsev) thiab lwm yam khoom siv raw hauv lub cub tawg tiv thaiv los ntawm kev kub siab smelting. Tam sim no, peb cov khoom lag luam ntawm silicon carbide muab faib ua ob hom silicon carbide dub thiab silicon carbide ntsuab, yog siv lead ua hexagonal, qhov hnyav tshwj xeeb yog 3.20 ~ 3.25, microhardness yog 2840 ~ 3320kg / mm2.

5 lub ntsiab siv ntawm silicon carbide

1. Daim ntawv thov ntawm kev lag luam hlau tsis yog ferrous

Kev siv silicon carbide muaj kev tiv taus kub siab, muaj zog, ua tau zoo thermal conductivity, thiab kuj cuam tshuam, thiab siv ua cov khoom siv cua sov tsis ncaj qha rau qhov kub siab, xws li lub thawv khov kho distillation furnace. Lub tais distillation furnace, aluminium electrolyzer, tooj liab melting furnace lining, zinc hmoov furnace arc plate, thermocouple protection tube, thiab lwm yam.

2, daim ntawv thov kev lag luam hlau

Siv cov tshuaj tiv thaiv xeb ntawm silicon carbide. Tiv taus kev co cua sov thiab kev hnav. Kev ua kom sov zoo, siv rau cov khoom siv hluav taws xob loj kom txhim kho lub neej ua haujlwm.

3, daim ntawv thov ntawm metallurgy thiab kev lag luam ua cov khoom siv minerals

Qhov nyuaj ntawm silicon carbide yog qhov thib ob tom qab pob zeb diamond, nrog kev ua haujlwm zoo tiv taus kev hnav, yog cov khoom zoo tagnrho rau cov kav dej, impeller, twj tso kua mis, cyclone, thiab thoob khib nyiab, nws cov kev ua haujlwm tiv taus kev hnav yog hlau cam khwb cia. Roj hmab muaj lub neej ua haujlwm ntawm 5-20 zaug, thiab kuj yog ib qho ntawm cov khoom zoo tshaj plaws rau kev ya dav hlau.

4, cov ntaub ntawv siv hauv tsev, kev sib tsoo log kev lag luam

Siv nws cov thermal conductivity. Cov hluav taws xob kub, cov yam ntxwv thermal muaj zog, kev tsim cov ntawv kiln, tsis yog tsuas yog txo qhov muaj peev xwm ntawm lub kiln, tab sis kuj txhim kho qhov muaj peev xwm ntawm lub kiln thiab cov khoom zoo, luv lub voj voog ntau lawm, cov khoom siv ceramic glaze ci sintering zoo tagnrho cov ntaub ntawv tsis ncaj.

5, kev siv hluav taws xob txuag

Nrog KEV UA KOM ZOO THAUM KUB thiab thermal stability, ua lub tshuab hloov pauv cua sov, kev siv roj tsawg dua 20%, roj txuag tau 35%, thiab kev tsim khoom nce ntxiv 20-30%. Tshwj xeeb, lub tshuab concentrator nrog lub raj xa dej tso rau hauv, nws qib hnav-tiv taus yog 6-7 npaug ntawm cov khoom siv hnav-tiv taus ib txwm muaj.
