Kubudirira uye kushandiswa kweargon kupururudzira uye kudhirowa zvidhinha zvekunyungudutsa simbi isina simbi muvira induction

Kuvapo kwema carbides, gasi inclusions uye oxide inclusions mune induction vira inonyorova simbi isina kukanda castings ndicho chikonzero chikuru chehurombo michina zvivakwa uye ngura kuramba. Izvo zvirimo zvezvakasiyana inclusions mune isina simbi castings inowirirana nesimbi yakanyungudutswa muyakagadziriswa induction simbi Iyo kuchena kwakabatana zvakanyanya. Parizvino, yakawanda yeiyo induction yevira yekunyungudutsa kuti ibudise simbi isina waya inotora nzira yekugadzirisa, iyo isina yekunatsa basa. Iyo haigone kubvisa akasiyana inclusions akaunzwa panguva yekugadzirisa maitiro, uye mhando yesimbi yakanyungudutswa haigone kuvimbiswa zvinobudirira, zvichikonzera kuderera kwekukanda mamakisi. Maitiro ekuderedza zvirimo zvezvakasiyana inclusions zvakagadzirwa mukugadzirisa nzira yesimbi isina simbi castings ine hunyanzvi hwekuita uye yakaderera mutengo yave nyaya yekukurumidzira kune vagadziri veesimbi simbi castings inogadzirwa neyakagadziriswa induction simbi.

Maitiro ekuridza argon musimbi yakanyungudika uye kumutsa kubvisa mhando dzakasiyana dze inclusions rave chikamu chakakosha cheichi chiitiko chemabhizimusi makuru esimbi kugadzira simbi yepamusoro uye yepamusoro-kukosha. Kuburikidza neArgon kufuridza kunatsa, iyo yakaumbwa simbi inogona kuzadzisa chinangwa che degassing, decarburizing uye kubvisa oxide inclusions. Chinonyanya kukosha ndechekuti kana argon yapuritsirwa musimbi yakanyungudutswa ine chromium, iyo chromium yezvinhu zvakaumbwa nesimbi yakanyungudutswa panguva imwe chete. Hazvichinje. Zvinoenderana nezvinodiwa nekukurumidza pamusika, isu takagadzira aroni yekuvhuvhuta uye inofema zvidhinha inokodzera induction yekunyungudutsa simbi isina simbi, iyo inogona kudzikisira zvirimo zvezvakasiyana inclusions muiyo induction vira inonyorova simbi isina simbi maitiro nemutengo wakaderera uye wakanyanya kushanda, kunatsiridza iro giredhi rekukanda, uye gadzira isina simbi yekukanda vagadziri Wana zvakanaka hupfumi. Induction furimi yekunyungudika ine zvinhu zvitatu zvakakosha pazvidhinha zvinofema.

Kuchengetedzwa kwakanaka:

② Yakadzikama gasi kuyerera;

Hupenyu hwakakwana hwebasa.

Zvigadzirwa zvakagadzirwa nekutsvaga uye kusimudzira kwezvinhu zvechifemo chinofema chinonyanya kushandiswa muvira rekutsvaira simbi isina simbi. Iko tembiricha yekushandisa yakanyanya kukwirira, uye iyo nguva yekupururudza yeArgon uye yakazara yeargon inoputira nguva yevira. Naizvozvo, izvo zvinhu zvezvidhinha zvinofema zvinofanirwa kuve nekumira kwakanaka kune yakaumbwa nesimbi uye slag. Kukwanisika uye yakanaka yepamusoro tembiricha simba. Nekuda kwetembiricha yakakwira yekunyungudutsa simbi isina tsvina mukati menguva yevira, iyo viscosity yakadzika uye kukwana kwakasimba kwesimbi isina simbi yemvura, panoshandiswa zvidhinha zvegesi-zvinokwanisika zvidhinha. izvo zvigadzirwa zvegasi-zvinokwanisika zvidhinha zvinoshanda pamusoro, ichivharidzira gasi-inokwenenzverwa migero uye ichiita gasi kubvumidzwa Izvo zvidhinha zvinorasikirwa nemhepo yekufema basa. Nekudaro, zvimwe zvezvinhu zvakasvibirira zvidhinha zvinofema zvakagadziridzwa uye zvakagadziriswa kuti zviwirirane nekunyungudika kwesimbi isina tsvina.
