Kev siv cov silicon carbide

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

5 lub ntsiab siv ntawm silicon carbide

1. Daim ntawv thov ntawm non-ferrous hlau smelting kev lag luam

Kev siv cov silicon carbide muaj qhov kub thiab txias tsis kam, siab zog, zoo thermal conductivity, cuam tshuam tsis kam, raws li kub kub indirect cua sov khoom, xws li cov khoom tank distillation rauv. Distillation furnace tais, txhuas electrolyzer, tooj liab melting rauv hauv ob sab phlu, zinc hmoov rauv arc phaj, thermocouple tiv thaiv raj, thiab lwm yam.

2, steel kev lag luam kev siv

Siv cov tshuaj tiv thaiv corrosion ntawm silicon carbide. Resistant rau kub poob siab thiab hnav. Zoo thermal conductivity, siv rau loj tawg rauv hauv ob sab phlu los txhim kho lub neej kev pab cuam.

3, daim ntawv thov ntawm metallurgy thiab ntxhia ua kev lag luam

Silicon carbide hardness yog thib ob tsuas yog pob zeb diamond, nrog rau kev hnav-tiv taus kev ua tau zoo, yog hnav-tiv thaiv kav, impeller, twj tso kua mis chamber, cyclone, ore thoob hauv ob sab phlu zoo tagnrho cov khoom, nws hnav-tiv taus kev ua tau zoo yog cam khwb cia hlau. Roj hmab muaj kev pab cuam lub neej ntawm 5-20 lub sij hawm, thiab kuj yog ib qho ntawm cov ntaub ntawv zoo tshaj plaws rau aviation flight runway.

4, lub tsev ntaub ntawv ceramics, sib tsoo log kev lag luam daim ntaub ntawv

Siv nws cov thermal conductivity. Thaum tshav kub kub hluav taws xob, cov yam ntxwv siab thermal zog, kev tsim cov ntawv ci, tsis tsuas yog tuaj yeem txo lub peev xwm ntawm kiln, tab sis kuj txhim kho lub peev xwm ntawm kiln thiab cov khoom lag luam zoo, txo lub voj voog ntau lawm, ceramic glaze ci sintering zoo tagnrho cov ntaub ntawv tsis ncaj.

5, kev siv hluav taws xob txuag

Nrog rau kev siv hluav taws xob zoo thiab thermal stability, raws li cov khoom siv hluav taws xob sib txawv, cov roj siv tau txo qis los ntawm 20%, cov roj tau txais kev cawmdim los ntawm 35%, thiab cov khoom tsim tau nce 20-30%. Hauv particular, lub mine concentrator nrog cov xaim xaim tso rau hauv, nws cov qib hnav-tiv taus yog 6-7 npaug ntawm cov khoom hnav-tiv taus.
