FAQ 1: Lub luag haujlwm ntawm silicon carbide crucibles hauv kev lag luam aluminium smelting yog dab tsi?
Teb: Silicon carbide crucibles tau siv dav hauv kev lag luam aluminium smelting vim lawv cov thermal conductivity, thermal shock resistance, thiab tshuaj lom neeg zoo heev. Cov crucibles yog siv los yaj thiab nchuav molten aluminium, thiab lawv muaj peev xwm tiv taus qhov kub thiab txias thiab hnyav tshuaj. Cov khoom siv silicon carbide muab qhov chaw ruaj khov thiab muaj kev nyab xeeb rau cov txheej txheem smelting, kom ntseeg tau tias aluminium yog qhov zoo tshaj plaws. Tsis tas li ntawd, cov crucibles yog qhov ruaj khov thiab tuaj yeem siv rau ntau lub voj voog ntawm smelting, ua rau lawv muaj txiaj ntsig zoo rau cov tuam txhab smelting aluminium.
FAQ 2: Dab tsi yog cov txiaj ntsig ntawm kev siv silicon carbide crucibles hauv kev lag luam tooj liab smelting?
Teb: Kev lag luam tooj liab smelting yuav tsum muaj cov crucibles uas muaj peev xwm tiv taus qhov kub thiab txias thiab hnyav ib puag ncig. Silicon carbide crucibles yog qhov kev xaiv zoo tshaj plaws rau daim ntawv thov no vim tias lawv muaj cov thermal conductivity thiab cov tshuaj tiv thaiv zoo heev. Cov crucibles yog siv los yaj thiab ncuav tooj liab, thiab lawv tuaj yeem tiv taus kub txog 1600 degree. Silicon carbide crucibles kuj muaj cov thermal expansion coefficient tsawg, uas txhais tau hais tias lawv tsis tshua muaj kev tawg lossis tawg thaum lub sij hawm smelting. Qhov kev ua haujlwm ntev no ua kom ntseeg tau tias cov txheej txheem tooj liab smelting muaj txiaj ntsig zoo thiab raug nqi, thiab cov txiaj ntsig tau txais txiaj ntsig zoo tshaj plaws.
FAQ 3: Koj ua li cas thiaj tswj tau silicon carbide crucibles?
Teb: Kev saib xyuas kom zoo ntawm silicon carbide crucibles yog qhov tseem ceeb los txuas lawv lub neej thiab ua kom lawv ua tau zoo. Txhawm rau tswj cov crucibles, nws raug nquahu kom preheat lawv mus rau qhov kub thiab txias ua ntej siv. Cov kauj ruam preheat no pab tiv thaiv thermal shock, uas tuaj yeem ua rau tawg thiab ua rau lub crucible tsis muaj zog. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom tsis txhob hloov pauv kub ceev thaum lub sij hawm smelting, vim qhov no tuaj yeem ua rau thermal poob siab thiab ua rau lub crucible puas. Tom qab siv, lub crucible yuav tsum tau tso cai kom txias maj mam, thiab lwm yam hlau molten yuav tsum tau muab tshem tawm. Nws tseem yog ib qho tseem ceeb uas yuav tau soj ntsuam cov crucibles tsis tu ncua rau tej yam tshwm sim ntawm kev puas tsuaj los yog hnav, thiab hloov lawv yog tias tsim nyog. Nrog kev tu thiab tu kom zoo, silicon carbide crucibles tuaj yeem muab kev ua tau zoo thiab ua haujlwm ntev rau ntau yam kev siv.
