Zvidhinha zveMagnesia Carbon: Mhinduro Inokosha Yekudzora Matanda Esimbi

Muindasitiri yekugadzira simbi, chirongo chesimbi mudziyo unokosha unotakura, unobata, uye unobata simbi yakanyungudutswa pakati pemaitiro akasiyana ekugadzira. Kushanda kwayo kunokanganisa zvakananga kunaka kwesimbi, kushanda zvakanaka kwekugadzira, uye mari yekushandisa. Zvisinei, simbi yakanyungudutswa inosvika pakupisa kwakanyanya kusvika 1,600°C kana kupfuura, uye inosanganawo nemarara akasimba, kukurwa kwemagetsi, uye kupisa kwakanyanya—zvichikonzera matambudziko makuru kune zvinhu zvinoramba zviri mukati mechirongo chesimbi. Apa ndipo panowanikwa.zvidhinha zve magnesium kabhoni(Zvidhinha zveMgO-C) zvinoonekwa semhinduro yepamusoro, zvichipa kugara kwenguva refu uye kuvimbika pakushanda kwesimbi.

Nei Zvidhinha zveMagnesium Carbon Zvichikosha paMatanda eSimbi​

Madhishi esimbi anoda zvinhu zvinoramba zvichishanda izvo zvinogona kumira mumamiriro ezvinhu akaoma pasina kukanganisa mashandiro. Zvidhinha zvechinyakare zvinoramba zvichishanda zvinowanzotadza kusangana nezvinodiwa izvi, zvichiita kuti zvitsiviwe kakawanda, nguva yekugadzira ishande, uye mitengo yakawedzera. Zvisinei, zvidhinha zve magnesium carbon zvinosanganisa simba re high-purity magnesia (MgO) ne graphite kugadzirisa matambudziko ese akakosha e steel ladle lining:

1. Kuramba Kusina Kunaka Kwekupisa Kwakanyanya

Magnesia, chinhu chikuru chezvidhinha zveMgO-C, ine nzvimbo yekunyunguduka yakanyanya kusvika 2,800°C—inodarika tembiricha yepamusoro yesimbi yakanyungudutswa. Kana ikasanganiswa negraphite (chinhu chine kugadzikana kwakanaka kwekupisa), zvidhinha zvemagnesium carbon zvinochengetedza chimiro chazvo kunyangwe kana zvikabatwa kwenguva refu nesimbi yakanyungudutswa ye1,600+°C. Kuramba uku kunodzivirira kupfava, kushanduka, kana kunyunguduka kwezvidhinha, zvichiita kuti chidhinha chesimbi chirambe chakachengeteka uye chichishanda kwenguva yakareba.​

2. Kuramba Kupisa Kwesimbi Nekuora Kwemhando Yepamusoro​

Simbi yakanyungudutswa inoperekedzwa nemaslag—zvigadzirwa zvakapfuma muma oxides (akadai seSiO₂, Al₂O₃, uye FeO) zvinokuvadza zvakanyanya kune zvinoramba. Magnesia iri muzvidhinha zveMgO-C inopindirana zvishoma nemaslag aya, ichigadzira denderedzwa rakakora, risingapindi mvura pamusoro pezvidhinha rinovhara kupinda kweslag. Kusiyana nezvidhinha zvealumina-silica, izvo zvinokurumidza kupwanywa nemaslag ane acidic kana basic, zvidhinha zvemagnesium carbon zvinochengetedza ukobvu hwazvo, zvichideredza njodzi yekubuda kweladle.​

3. Kuramba Kupisa Kwakanaka Kwekupisa​

Madhishi esimbi anodziiswa kakawanda (kubata simbi yakanyungudutswa) uye kutonhora (panguva yekugadzirisa kana nguva yekusashanda)—maitiro anokonzera kuvhunduka kwekupisa. Kana zvinhu zvinoramba zvichichinja tembiricha nekukurumidza, zvinotsemuka, zvichikonzera kutadza kushanda zvakanaka. Graphite iri muzvidhinha zve magnesium carbon inoshanda se "buffer," ichibvisa kushushikana kwekupisa uye ichidzivirira kuumbwa kwetsekwe. Izvi zvinoreva kuti zvidhinha zveMgO-C zvinogona kutsungirira mazana emitambo yekudziya-kutonhodza pasina kurasikirwa nekushanda, zvichiwedzera hupenyu hwebasa redhishi resimbi.​

4. Kuderedzwa Kwemari Yekupfeka Nekugadzirisa​

Kupera kwemidziyo kubva mukukurunga simbi yakanyungudutswa, kufamba kwendiro, uye kukwenya slag ndeimwe dambudziko guru kune zvinoramba simbi. Magnesium carbon brick ine simba guru remuchina uye kuomarara, nekuda kwekubatana pakati pemagnesia grains negraphite. Kugara kwenguva refu uku kunoderedza kupera kwezvidhinha, zvichiita kuti ndiro ishande kwenguva yakareba pakati pema relinings. Kune simbi, izvi zvinoreva kuti nguva shoma yekushanda, mari shoma yevashandi yekutsiva inoramba, uye purogiramu yekugadzira yakaenderana.​

Mashandisirwo Akakosha eMagnesium Carbon Bricks muSimbi Ladles​

Zvidhinha zveMagnesium carbon hazvisi zvemhando imwe chete—zvakagadzirirwa zvikamu zvakasiyana zvesimbi zvichibva padanho rekumanikidzwa:

Chidzitiro chepasi nemadziro:Madziro epasi neapasi echirongo anosangana zvakananga kwenguva refu nesimbi yakanyungudutswa uye marara. Pano, zvidhinha zve magnesium carbon zvine density yakakwira (zvine 10-20% graphite content) zvinoshandiswa kudzivirira ngura nekusakara.​

Mutsetse weSlag yeLadle:Mutsetse wetsvina ndiyo nzvimbo inonyanya kukuvadzwa, sezvo ichitarisana nekusangana netsvina inoparadza uye kupisa kwakanyanya. Zvidhinha zve magnesium carbon zvepamusoro (zvine graphite yakawanda uye antioxidants dzakawedzera seAl kana Si) zviri kuiswa pano kuti zviwedzere hupenyu hwebasa.​

Nozzle yeChidziyo neHole reTap:Nzvimbo idzi dzinoda zvidhinha zvine simba rekupisa uye zvinodzivirira kukurwa kwevhu kuti simbi yakanyungudutswa ifambe zvakanaka. Zvidhinha zveMgO-C zvine magnesia yakanatswa zvinoshandiswa kudzivirira kuvharika uye kuwedzera nguva yekushanda kwemuchina.​

Mabhenefiti emiti yesimbi: Kupfuura kugara kwenguva refu​

Kusarudza zvidhinha zve magnesium carbon zvesimbi yekuisa machira esimbi kunoita kuti pave nemabhenefiti anooneka kune vagadziri vesimbi:

Hunhu Hwakagadziridzwa hweSimbi:Nekudzivirira kukurwa kwesimbi isingapindi mvura, zvidhinha zveMgO-C zvinoderedza njodzi yekuti simbi yakanyungudutswa iparare mvura - zvichiita kuti pave nekuumbwa kwemakemikoro kwakafanana uye kuti pave nekusakwana kushoma muzvigadzirwa zvesimbi zvakapedzwa.​

Kuchengetedza Simba:Kupisa kwakanyanya kwegraphite muzvidhinha zveMgO-C kunobatsira kuchengetedza kupisa mundiro, zvichideredza kudiwa kwekudziyazve simbi yakanyungudutswa. Izvi zvinoderedza kushandiswa kwemafuta uye kuburitswa kwekabhoni.​
Hupenyu Hwenguva Refu Yekushanda Kwechidziva: Paavhareji, machira esimbi ane magnesium carbon anogara kwenguva yakareba ka2-3 kupfuura machira ekare asina kusimba. Kune chidziva chesimbi chakajairika, izvi zvinoreva kuaisa patsva kamwe chete pamwedzi 6-12 yega yega, zvichienzaniswa neka2-3 pagore nezvimwe zvinhu.

Sarudza Zvidhinha zveMagnesium Carbon zvemhando yepamusoro zveMaradhi ako eSimbi​

Hazvisi zvese zvidhinha zve magnesium carbon zvakagadzirwa zvakaenzana. Kuti unyatsoita basa, tsvaga zvigadzirwa zvine:

Magnesia yakachena kwazvo (95%+ MgO) kuti ive nechokwadi chekuti ngura haipindi.

Graphite yepamusoro-soro (dota shoma) kuti isanyanya kupisa.

Zvinhu zvinosimbisa simbi zvine hunyanzvi uye zvinorwisa antioxidants kuti zvisimbise zvidhinha uye zvidzivirire graphite oxidation.

At Shandong Robert Refractory, isu tine hunyanzvi mukugadzira zvidhinha zve magnesium carbon zvemhando yepamusoro zvakagadzirirwa kushandiswa kwendiro dzesimbi. Zvigadzirwa zvedu zvinodzorwa zvakanyanya—kubva pakusarudzwa kwezvinhu zvakabikwa kusvika pakuyedzwa kwekupedzisira—kuti zvive nechokwadi chekuti zvinosangana nezvinodiwa zvakanyanya zvekugadzira simbi. Kunyangwe iwe uchishandisa chigayo chidiki chesimbi kana fekitori hombe yakabatana, tinogona kupa mhinduro dzakagadzirirwa iwe kuderedza mitengo yako uye kuwedzera kugona kwako.​
