Txhim khu kev qha Crucibles rau Melting thiab Casting
piav qhia
Graphite crucible, tseem hu ua molten tooj liab clad, molten tooj liab, thiab lwm yam, hais txog ib hom crucible raug rho tawm haujlwm los ntawm graphite, av nplaum, silica thiab wax pob zeb.
Nta
Nws muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, muaj zog thermal conductivity, zoo corrosion kuj thiab kev pab lub neej ntev.Nyob rau hauv tus txheej txheem ntawm kev siv kub kub, lub coefficient ntawm thermal expansion yog me me, thiab nws muaj tej yam strain resistance rau ceev ceev txias thiab ceev cua sov.Nws muaj zog corrosion kuj rau acidic thiab alkaline daws, muaj tshuaj lom neeg ruaj ntseg zoo, thiab tsis koom nrog cov tshuaj tiv thaiv thaum lub sij hawm smelting txheej txheem.Lub puab phab ntsa ntawm cov graphite crucible yog du, thiab cov kua hlau melted tsis yooj yim rau xau thiab ua raws li cov phab ntsa sab hauv ntawm lub crucible, kom cov kua hlau muaj fluidity zoo thiab castability, thiab yog haum rau ntau yam pwm casting.
Txheej txheem ntau lawm
Cov txheej txheem tsim khoom ntawm graphite crucible tuaj yeem muab faib ua peb hom: tes molding, rotational molding thiab compression molding.
Daim ntawv thov
Graphite crucibles feem ntau yog siv los smelt non-ferrous hlau xws li tooj liab, tooj dag, kub, nyiaj, zinc thiab txhuas thiab lawv cov alloys.
