Dab tsi koj tuaj yeem yaj hauv graphite crucible?
Graphite cross yog feem ntau siv nyob rau hauv Metallurgy thiab Foundry cov ntawv thov rau melting cov hlau vim lawv cov kev ua haujlwm kub, thiab tshuaj lom neeg ua haujlwm.
Graphite shreglesMuaj peev xwm withstand huab huab cua tsis muaj melting lossis reacting nrog cov hlau, ua rau nws haum rau melting ntau yam ntawm cov hlau, suav nrog:
Txhuas:Graphite cross yog feem ntau siv rau melting aluminium thiab nws cov alloys hauv ntau lub thawv thiab cov haujlwm ua haujlwm. Aluminium muaj qhov tseem ceeb melting point (kwv yees li 660 degree lossis 1220 degree f), zoo nyob rau hauv qhov ntsuas kub uas muaj peev xwm tiv thaiv tau.
Tooj liab:Tooj liab thiab nws cov alloys, xws li bronze, xws li tooj dag thiab tooj dag, tseem tuaj yeem yaj hauv graphite cruca crucles. Copper has a higher melting point compared to aluminum (approximately 1085 degree or 1985 degree F), but graphite crucibles are capable of withstanding the temperatures required for copper melting.

Kub thiab Nyiaj:Graphite cross yog nquag siv rau melting cov hlau zoo li kub thiab nyiaj hauv cov hniav nyiaj hniav kub ua, kho dua tshiab, thiab kev lag luam Casting. Ob qho kub thiab nyiaj tau muaj cov ntsiab lus tseem ceeb (1064 degree F rau Nyiaj), tab sis graph1 degree tuaj yeem lis cov ntsuas kub uas tsim nyog rau melting cov hlau.
Hlau thiab Hlau:Thaum graphite crucibles tuaj yeem tiv thaiv qhov kub me me rau melting hlau thiab hlau, lawv feem ntau siv rau cov ntsiab lus ntawm lawv cov kev txiav txim siab. Hlau melts ntawm kwv yees li ntawm 1538 degree f), thaum cov neeg hlau yaj ntawm qhov kub ntawm 1310 degree (2500 degree f), nyob ntawm lub alloy muaj pes tsawg leeg.
Lead thiab Tin:Graphite crucles yog qhov haum rau melting tsawg-melting-pointting xws li hmoov txhuas xws li txhuas txhuas thiab tin. Ua rau melts ntawm ib qho kub tsawg ntawm 327.5 Degree (621.5 Degree L), zoo nyob rau hauv lub peev xwm ntawm graphite crucibles.
Graphite (refererated) crucailes
Zinc:Zinc thiab nws cov alloys kuj tseem tuaj yeem tau melted hauv graphite cruca crucles. Zinc muaj lub ntsiab lus melting ntawm kwv yees li ntawm 419.5 degree (787.1 Degree F), ua rau nws sib xws nrog graphibles.
Ntxiv rau cov hlau teev saum toj no, graphite crucibles kuj tseem siv tau rau melting lwm yam hlau thiab alloys nrog melting cov ntsiab lus nyob rau hauv qhov kub thiab txias graphite tuaj yeem tiv thaiv tau. Txawm li cas los xij, nws yog ib qho tseem ceeb rau kev xav txog qhov loj me, thermal poob siab kuj, thiab sib zog nrog cov alloys tshwj xeeb thaum xaiv cov neeg tua tsiaj.
