Girke-girke na Graphite Silicon Carbide Crucibles: Maɓalli don Ƙarfafa Ƙarfafa Ƙarfafawa

A duniyar kimiyyar ƙarfe da kayan aiki,da cruciblekayan aiki ne mai mahimmanci don narkewa da simintin ƙarfe.Daga cikin nau'ikan crucibles iri-iri, crucibles silicon carbide (SiC) graphite sun fice don keɓancewar kaddarorin su, kamar babban ƙarfin zafin jiki, ingantaccen juriya na zafin zafi, da ingantaccen ingantaccen sinadarai.A cikin wannan labarin, za mu shiga cikin girke-girke na graphite SiC crucibles da kuma gano yadda abun da ke ciki ke ba da gudummawa ga gagarumin aikinsu a aikace-aikacen zafin jiki.

Abubuwan da ake bukata

Abubuwan farko na graphite SiC crucibles sune flake graphite da silicon carbide.Flake graphite, yawanci ya ƙunshi 40% -50% na crucible, yana ba da kyakkyawan yanayin zafi da lubricity, wanda ke taimakawa cikin sauƙin sakin simintin ƙarfe.Silicon carbide, wanda ke samar da kashi 20% -50% na crucible, shine ke da alhakin juriyar girgizar zafi mai zafi da kwanciyar hankali na sinadarai a yanayin zafi mai tsayi.

Ƙarin Abubuwan da aka Haɓaka don Ƙarfafa Ayyuka

Don ƙara haɓaka aikin zafi mai zafi da kwanciyar hankali na sinadarai na crucible, ana ƙara ƙarin abubuwan da aka gyara zuwa girke-girke:

1. Elemental silicon foda (4% -10%): Yana haɓaka ƙarfin zafin jiki mai ƙarfi da juriya na iskar shaka na crucible.
2. Boron carbide foda (1% -5%): Yana ƙaruwa da kwanciyar hankali da juriya ga karafa masu lalata.
3. Clay (5% -15%): Yana aiki azaman mai ɗaure kuma yana haɓaka ƙarfin injina da kwanciyar hankali na crucible.
4. Thermosetting ɗaure (5% -10%): Yana taimakawa wajen haɗa duk abubuwan haɗin gwiwa tare don samar da tsarin haɗin gwiwa.

Formula Mai Ƙarshe

Don aikace-aikacen da ke buƙatar yin aiki mafi girma, ana amfani da dabarar ƙwaƙƙwarar graphite mai tsayi.Wannan dabarar ta ƙunshi 98% graphite barbashi, 2% calcium oxide, 1% zirconium oxide, 1% boric acid, 1% sodium silicate, da 1% aluminum silicate.Waɗannan ƙarin sinadarai suna ba da juriya mara misaltuwa ga yanayin zafi da zafin yanayi.

Tsarin Masana'antu

Shiri na graphite SiC crucibles ya ƙunshi tsari mai mahimmanci.Da farko, flake graphite da silicon carbide suna gauraye sosai.Sa'an nan, siliki foda, boron carbide foda, yumbu, da thermosetting daure ana saka a cikin cakuda.Sannan ana matse cakuda zuwa siffa ta amfani da injin buga sanyi.A ƙarshe, ƙwanƙwasa masu sifofi suna zub da jini a cikin tanderu mai zafi don haɓaka ƙarfin injin su da kwanciyar hankali na zafi.

Aikace-aikace da Fa'idodi

Graphite SiC crucibles ana amfani da su sosai a cikin masana'antar ƙarfe don narkewa da fitar da karafa kamar ƙarfe, ƙarfe, jan ƙarfe, da aluminium.Ƙarfin wutar lantarkin su yana tabbatar da dumama iri ɗaya kuma yana rage yawan kuzari.Babban juriyar girgiza zafin zafi yana rage haɗarin fashewa yayin saurin canjin yanayin zafi, yayin da kwanciyar hankalinsu na sinadari yana tabbatar da tsabtar narkakken ƙarfe.

A ƙarshe, girke-girke na graphite silicon carbide crucibles shine haɗakar kayan da aka daidaita da kyau waɗanda ke ba da ma'auni na ƙimar zafi, juriya na zafi, da kwanciyar hankali na sinadarai.Wannan abun da ke ciki ya sa su zama makawa a fagen aikin ƙarfe, inda suke taka muhimmiyar rawa wajen ingantaccen narke da kuma zubar da karafa.
