Tungsten molybdenum crucible W crucible Mo crucible
Whakaaturanga Hua
Ka rite ki te whakarewa nonferrous, tungsten he tino tiketike kaha me te pakeke.Na tenei 2.Main Features, ko te tungsten carbide me te pakeke nui me te kaha o te kakahu kaha kua whakamahia i roto i nga taputapu tapahi me nga taputapu maina i runga i te waahanga nui.
Ko te Tungsten te whakarewa whakaahuru me te ira whakarewa teitei.Ko nga konganuku whaanui me te ira whakarewa teitei ake i te 1650 ℃ me tetahi rahui me te ira whakarewa teitei ake i te ira whakarewa o te zirconium (1852 ℃) ka kiia he konganuku whakaahuru.Ko nga konganuku whakamaarama ko te tungsten, tantalum, molybdenum, niobium, hafnium, chromium, vanadium, zirconium, me te titanium.Ka rite ki te konganuku refractory, te painga tino nui o Tungsten ko e he pai kaha teitei pāmahana me te pai te waikura ātete ki te whakarewa alkali konganuku me te kohu.Ka kitea i runga ake i te 1000 ℃.He rite tonu nga ahuatanga o te molybdenum me te tungsten, te ira koropuke rongonui me te kawe hiko, te whakarea whakarea whakarea waiariki iti, me te ngawari ki te tukatuka atu i te tungsten.
He pai te mahi o te kawe wera o te konganuku molybdenum [135 Watts / (m · tuwhera)] ki te wera motuhake [0.276 kJ / (kg · tuwhera)], na te mea he whiriwhiringa maori mo te ru werawera me te ngenge waiariki.Ko te rewa ko te 2620 ℃, tuarua ki te tungsten me te tantalum, engari he iti rawa tona kiato, no reira ko tona kaha motuhake (kaha / kiato) he nui atu i te tungsten, tantalum me etahi atu konganuku, he pai ake i roto i nga tono me nga whakaritenga taumaha nui.He kaha tonu te molybdenum i te 1,200 ℃.
Nga waahanga matua
He teitei te rewa o te tungsten, he iti rawa te pehanga kohu, he iti te tere whakaetonga.Ko nga ahuatanga matū o te tungsten he tino pumau, kaore i te urupare ki te hau me te wai i te pāmahana o te rūma, kaore e taea te whakakore i te waikawa waikawa, te waikawa pungatara, te waikawa nitric me te otinga alkali.Whakarewa i roto i te wai kingi me te ranunga o te waikawa nitric me te waikawa waiwaro.I te pāmahana teitei, ka taea te whakakotahi ki te maota, bromine, iodine, waro, hauota, whanariki, engari kaua ki te hauwai.Ko te ira whakakoero tungsten parakore ka tae ki te 3410 ℃, he kaha tonu te kaha ki te 1300 ℃, i te mea he kaha te kaha o te koranu i runga i te tungsten i te 1800 ℃, he pai te ātete ki te wera wera.
Tono Hua
Na te kaha o te tungsten, te pakeke teitei, Na, kua waiho hei mea tino pai mo te hanga i nga konupuku motuhake teitei, Ka wehewehea enei waahanga motuhake ki te W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag me etahi atu raupapa nui, Ko tenei momo koranu te2.Main Featuress o te ōwehenga teitei, te kaha teitei, te kaha o te rauropi absorption, te kawe waiariki nui, te whakareatanga whakareatanga waiariki iti, te pai o te kawe hiko, te weldability me te pai o te tukatuka, Kei te whakamahia nuitia i roto i te aerospace, rererangi, hoia, keri hinu, taputapu hiko, rongoa me etahi atu ahumahi, Pērā i te hanga patu, totohu wera, te hama toenga urungi me nga taonga whakapiri penei i te pana maripi, te ara iahiko, te hiko hiko, aha atu.
mara hiko
Tungsten he kirihou kaha, iti tere whakaetonga, ira whakarewa tiketike me te kaha tuku irahiko kaha, no reira e whakamahia whānuitia ana te tungsten me ona koranu i roto i te ahumahi hiko me te hiko.Hei tauira, ko te waea tungsten he nui te reiti maramara me te roa o te mahi ratonga, na reira ka whakamahia nuitia ki te hanga i nga momo kakawaea pupuhi, penei i te rama rama, rama tungsten iodine, ka taea hoki te whakamahi waea tungsten ki te hanga i te cathode wera tika. kuaha o te ngongo oscillator hiko me nga momo taputapu hiko i roto i te taha whakawera cathode waiariki.Ko te2.Main Featuress o Tungsten hanga pai hoki te reira mo TIG fehokotaki'anga me ētahi atu rauemi hiko mo te mahi rite.
Te ahumahi matū
Ko nga pūhui tungsten e whakamahia ana hei whakakorikori me nga tae pararopi, penei i te tungsten disulfide ka whakamahia hei whakahinuhinu me te whakakorikori i roto i te penehīni waihanga, ka whakamahia te konupora tungsten oxide i roto i nga peita, te konupūmā, te konupora konupora tungsten te whakamahia i roto i te phosphors.
Ētahi atu wāhi
Na te mea he rite te tungsten ki te karaehe silicate boryl, ka whakamahia hei hanga hiri karaihe, hiri whakarewa ranei.He iti te tairongo o te Tungsten ka whakamahia hei hanga whakapaipai koura parakore teitei.I tua atu, ka whakamahia ano te tungsten i roto i te rongoa radioactive, a ka whakamahia ano e etahi taputapu te waea tungsten.
