Alxanka Cast Alloy NiFe-1 u adkaysta oksaydhation-ka birta alxanka
Usha alxanka birta ah waxaa inta badan loo isticmaalaa in lagu xalliyo qolof engine, cover jidhka, mashiinka saldhigga, tuurista ilkaha muuqan jabka wheel, dildilaaca, xidho, tamping godka dhibaatooyinka alxanka.Sababtoo ah kaarboonka sare ee kaarboonka, qaabdhismeedka aan sinnayn, xoogga hooseeya iyo caagga liidata, birta birta ah ee birta ah ayaa ah walxo liidata, taas oo ay fududahay in la soo saaro dildilaaca inta lagu jiro alxanka, way adagtahay in la gooyo.Si loo gaaro natiijooyin lagu qanco ee alxanka iyo hagaajinta alxanka birta, waxaa muhiim ah in fiiro gaar ah loo yeesho "Waxyaabaha Saddexda qaybood ah iyo habka todobada qaybood", ma aha oo kaliya in la doorto usha alxanka, laakiin sidoo kale in la qaato habka hagaajinta hagaajinta ku habboon.
Habka alxanka ee soo socda ayaa lagula talinayaa inuu tixraac u noqdo alxanka kabka iyo dayactirka alxanka: 1, marka hore ka saar qaybaha alxanka ee dhoobada, ciidda, biyaha, miridhka iyo qashinka kale;Intaa waxaa dheer, lakabka kaarboon- saboolka ah iyo lakabka oksaydhka ee dusha sare ee shubka birta ee ka shaqeeya Heerkulka Sare iyo deegaanka uumiga muddo dheer waa in meesha laga saaraa.2. Marka loo eego qaabka iyo nooca cilladda qaybta alxanka ah, tallaabooyinka diyaarinta sida furitaanka jeexdin, dildilaaca ka hortagga daloolka daloolka iyo qaabaynta barkada dhalaalaysa ayaa la sameeyaa.3. Qaybaha u baahan alxanka qabow, ku sii kululee 500-600 ° C, dooro hadda ku habboon, alxanka joogtada ah, ilaali heerkulka preheating inta lagu jiro habka alxanka, dabool walxaha dahaarka ah sida budada asbestos isla markiiba ka dib alxanka, oo u ogolow si tartiib ah u qabooji, si loo hagaajiyo caabbinta dildilaaca iyo waxqabadkeeda.4. Waayo, qaybo ka mid ah alxanka qabow qabow, ka hortag biraha aasaasiga ah dhalaalid aad u badan, la yareeyo u janjeera cad, ka hortagga fiirsashada kulaylka badan, taasoo keentay in stress xad-dhaaf ah, hadda yar yar, arc gaaban iyo alxanka pass cidhiidhi ah waa in la isticmaalaa sida ugu fog ee suurtogalka ah ( dhererka baas kasta waa inuusan dhaafin 50mm) .Isla markiiba ka dib alxanka dubbe alxanka si aad u dejiso diiqada si looga hortago dildilaaca, ilaa heerkulku hoos ugu dhacay 60 darajo C oo ka hooseeya alxanka kale.5, fiiro gaar ah u yeelo godka arc marka la xirayo, si aad uga hortagto dillaaca xidhitaanka.
