Rudzi rutsva rwezvidhinha zvinofema zvinobatsira induction choto kubvisa tsvina

Kuvapo kwegasi inclusions uye oxide inclusions mucastings ndicho chikonzero chikuru chekushayikwa kwemaitiro emagetsi uye kushorwa kwekupokana kwe castings, uye zviri mukati mezvakasiyana-siyana zvinosanganisirwa mucastings zvine hukama zvakanyanya nekuchena kwesimbi yakanyungudutswa muchoto chekupinza. Kunyangwe AOD (Argon Oxygen Decarburization Refining Furnace), VOD (Vacuum Oxygen Blown Decarburization Refining Furnace) nemimwe michina yekunatsa ine mhedzisiro yakanaka, mari yekudyara uye yekushandisa yakakwira, uye haina kukodzera nhamba huru yediki uye yepakati-saizi. foundries. Parizvino, yakawanda yemaitiro ekugadzira castings mu induction furnaces inotora nzira yekugadziridza, iyo isina basa rekunatsa uye haigone kubvisa akasiyana inclusions akaunzwa mukati mekugadzirisa. Hunhu hwesimbi yakanyungudutswa haigone kuvimbiswa, zvichiita kuti pave negoho rakaderera uye giredhi yakaderera. Maitiro ekudzikisa zviri mukati meakasiyana inclusions anogadzirwa mune remelting process yestainless simbi castings nehunyanzvi hwepamusoro uye mutengo wakaderera yave nyaya yekukurumidzira kumabhizinesi anoshandisa induction furnaces kugadzira castings.

Kuiswa kwezvidhinha zvemhepo. Kuiswa kwechidhinha chinofema muchoto chemukati chiri nyore kwazvo. Hapana chikonzero chekuita shanduko huru yechimiro chechoto chemukati. Ingori gomba rakatenderera rine dhayamita ye40 mm kusvika ku60 mm inodonhedzwa pabhodhi reasbestos kana bhuroka rakagadzirirwa pasi pechoto kuti ritungamirire chidhinha chinofema. Iyo argon inovhuvhuta pombi inogona kuve yakashongedzerwa nemabhodhoro maindasitiri argon seyo argon sosi. Iyo nzira yekuvaka choto yevira yekupinza ine mhepo-inopindirwa zvidhinha yakafanana neyeyakajairwa induction furnace.

Chirevo chekuyedza chesimbi yakanyungudutswa chinoratidza kuti zviri mukati [O], [N] uye [H] musimbi yakanyungudutswa zvakadzikiswa zvakanyanya kana argon kuvhuvhuta nzira inoshandiswa kana ichienzaniswa neisina kuvhuvhuta argon. Panguva imwecheteyo, mushumo webvunzo wakaratidzawo kuti zviri mukati meisiri-spherical inclusions musimbi yakanyungudutswa yaive yakaderera pane yekuumba mwero, uye zviri mukati spherical oxide inclusions zvakasvika pachiyero che0.5A. Ichi chigumisiro chinoratidza kuti kushandiswa kweargon kuvhuvhuta maitiro nezvidhinha zvinofema mukati mepakati frequency induction furnace inogona kunyatso kuvandudza kunaka kwesimbi yakanyungudutswa uye pakupedzisira kunatsiridza giredhi rekukanda.
