Iwe Unoziva Kunyungudika KwemaAluminium Cans?

Aluminium magaba akajairika muhupenyu hwedu hwemazuva ese, achishanda semidziyo yezvinwiwa uye zvimwe zvigadzirwa zvevatengi.Magaba aya akagadzirwa kubva kune yakareruka, isingadziviriri, uye inogona kushandiswazve - aluminium.Kugadzirwa uye kudzokororwa kwemagaba ealuminium kunosanganisira maitiro akati wandei, kusanganisira kunyungudika kwealuminium.Muchinyorwa chino, tichaongorora inonakidza kunyunguduka kwemagaba ealuminium, tichitarisa pazvinhu zvakakosha senge aruminiyamu inonyunguduka choto, maajenti ekubvisa slag, ekunatsa, simbi silicon, uye furo ceramic sefa.

I. Aluminium Melting Furnace
Kunyunguduka kwemagaba ealuminium kunotanga nearuminiyamu yekunyunguduka kwevira, iyo inoita basa rakakosha mukushandura aruminiyamu yakasimba kuita yakanyunguduka.Kune marudzi akasiyana-siyana emavira anoshandiswa muindastiri, asi anonyanya kuzivikanwa anosanganisira anotevera:
Reverberatory Furnace: Choto ichi chakagadzirwa nechakaderera-mbiri, rectangular kamuri umo aruminiyamu inopisa zvisina kunanga kuburikidza neinopenya kupisa kubva padenga nemadziro.Choto chacho chinogona kusvika pakupisa kusvika ku1200 ° C, iyo inodarika zvakakwana kunyungudusa aluminium.
Crucible Furnace: Iyi mhando yevira inoshandisa refractory-lined crucible kubata iyo aluminium.Iyo crucible inopisa nemagetsi kana gasi-anopisa zvinopisa, uye iyo aluminium inonyungudika mukati mayo.
Induction Furnace: Choto ichi chinotsamira pane electromagnetic induction kugadzira kupisa mualuminium.Iyo nzira yakachena uye ine simba-inoshanda, zvichiita kuti ive sarudzo yakakurumbira yekunyungudutsa aluminium.

II.Slag Removal Agents
Munguva yekunyunguduka, tsvina mualuminium inogona kuumba chidimbu che slag pamusoro pesimbi yakanyungudutswa.Kuti uone kunaka kwechigadzirwa chekupedzisira, zvakakosha kubvisa slag.Slag ekubvisa vamiririri, vanozivikanwawo se fluxes, makemikari anofambisa kupatsanurwa kwe slag kubva kune yakanyungudutswa aluminium.Zvakajairwa slag ekubvisa vamiririri vanosanganisira zvinotevera:
Sodium Chloride (NaCl): Munyu uyu unobatsira mukupwanya slag, zvichiita kuti zvive nyore kubvisa.
Potassium Chloride (KCl): Kufanana nesodium chloride, potassium chloride inobatsira mukuparara kwe slag, ichikurudzira kuparadzaniswa kwayo kubva kune yakanyungudutswa aluminium.
Fluoride-based Fluxes: Izvi zvinoyerera zvinobatsira mukubvisa oxide tsvina uye zvakare kuderedza kunyungudika kwe slag, zvichiita kuti zvive nyore kubvisa.

III.Refining Agents

Kunatsa maajenti anoshandiswa kusimudzira kunaka kwealuminum yakanyungudutswa nekubvisa tsvina yakaita sehydrogen gasi uye inclusions.Mamwe akajairika ekunatsa maajenti anosanganisira anotevera:

Hexachloroethane (C2Cl6): Mushonga uyu unoora mualuminium yakanyungudutswa, uchibudisa chlorine gasi rinosangana netsvina, zvichiita kuti zvive nyore kubvisa.
Nitrogen Gasi (N2): Kana gasi renitrogen rikaputirwa nealuminium yakanyungudutswa, inobatsira kubvisa hydrogen gasi uye inclusions.
Argon Gasi (Ar): Kufanana nenitrogen, argon gasi inogona kushandiswa kubvisa hydrogen gasi uye inclusions kubva mualuminium yakanyungudutswa.

IV.Metallic Silicon

Metallic silicon inowedzerwa kune yakanyungudutswa aruminiyamu sechinhu chinosanganisa.Kuwedzerwa kwesimbi silicon kunonatsiridza mashandiro emuchina wechigadzirwa chekupedzisira, sekusimba kwayo nekuoma kwayo.Uyezve, silicon inobatsirawo mukunatsa aluminium yakanyungudutswa nekuita nekusachena uye nekusimudzira kubviswa kwavo.

Mukupedzisa, kunyunguduka kwemagaba ealuminium inzira yakaoma asi inonakidza inosanganisira akati wandei akakosha zvikamu nematanho.Iyo aruminiyamu yekunyungudutsa choto, ingave iri reverberatory, crucible, kana induction choto, inoshanda semusana wekuita, ichigonesa shanduko yealuminiyamu yakasimba kuita yakanyungudutswa.Slag ekubvisa maajenti, akadai sesodium chloride uye potassium chloride, anoita basa rakakosha mukubvisa tsvina uye kuve nechokwadi chemhando yealuminium yakanyungudutswa.Kunatsa maajenti, senge hexachloroethane uye nitrogen gasi, anowedzera kuwedzera kunaka nekubvisa hydrogen gasi uye inclusions.Kuwedzerwa kwesimbi silicon sechinhu chinosanganisa haingonatsiridze michina yechigadzirwa chekupedzisira asiwo inobatsira mukunatsa.Chekupedzisira, foam ceramic mafirita anobatsira mukucheneswa kwekupedzisira kwealuminium yakanyungudutswa, zvichikonzera yakachena uye yepamusoro-yemhando yekupedzisira chigadzirwa.Kunzwisisa zvinhu izvi zvakakosha uye matanho kunopa nzwisiso yakakosha mumaitiro anoshamisa ari kuseri kwekugadzirwa uye kudzokororwa kwemagaba ealuminium.
