Hastelloy C-4
Kufotokozera Kwachidule:
Hastelloy C-4 (UNS NO6455)
Mawonekedwe a Hastelloy C-4 ndi Chidule cha Mapulogalamu:
Aloyi ndi austenitic low carbon nickel-molybdenum-chromium alloy.Kusiyana kwakukulu pakati pa Nicrofer 6616 hMo ndi ma alloys ena ofanana ndi mankhwala omwe adapangidwa kale ndi otsika carbon, silicon, iron ndi tungsten.Izi mankhwala zikuchokera amapereka bata kwambiri pa 650-1040 ° C ndi bwino kukana intergranular dzimbiri, kupewa chiwopsezo m'mphepete mzere dzimbiri ndi kuwotcherera HAZ dzimbiri pansi pa zinthu zoyenera kupanga.Aloyi amagwiritsidwa ntchito mu makina a flue gas desulfurization, pickling ndi acid regeneration plant, acetic acid ndi ulimi wa mankhwala, titanium dioxide kupanga (njira ya chloride), electrolytic plating.

Ntchito ya Hastelloy C-4 ndi zofunika:
1, mu ndondomeko kutentha mankhwala sangakhoze kukhudzana ndi sulfure, phosphorous, kutsogolera ndi zina otsika mfundo zitsulo, kapena aloyi adzakhala Chimaona, ayenera kulabadira kuchotsa monga chizindikiro utoto, kutentha chizindikiro utoto, makrayoni achikuda, mafuta, mafuta. ndi zinyalala zina.M'munsi sulfure zili mafuta bwino, sulfure zili gasi zachilengedwe ayenera kukhala zosakwana 0.1%, sulfure zili mafuta olemera ayenera kukhala zosakwana 0,5%.Kutentha kwa ng'anjo yamagetsi ndi chisankho chabwino, chifukwa ng'anjo yamagetsi imatha kuyendetsa bwino kutentha ndi mpweya wa ng'anjo ndi woyera.Ngati chitofu cha gasi chimakhala chokwanira, mutha kusankha.
2, aloyi matenthedwe processing kutentha osiyanasiyana 1080 ℃ ~ 900 ℃, kuzirala njira madzi kuzirala kapena zina mofulumira kuzirala.Kuonetsetsa kukana dzimbiri bwino, kutentha mankhwala ayenera kuchitidwa pambuyo njira kutentha mankhwala.
