Nhau

Munyika yemaindasitiri anopisa zvakanyanya, kuwana zvinhu zvinovimbika zvinogona kutsungirira kupisa kwakanyanya, ngura, uye kusakara kwakakosha. Ndipo panodiwa.kurova kwemakumbo(inozivikanwawo semusanganiswa weramming) inopinda. Iyi midziyo isina kuumbwa inogumbura, yakagadzirwa nemidziyo yemhando yepamusoro inogumbura, hupfu, uye zvinosunga, yave chikamu chakakosha chemaitiro mazhinji emaindasitiri. Ngationgororei mashandisirwo ayo makuru uye kuti nei iri sarudzo yepamusoro kumabhizinesi pasi rese.

1. Simbi: Mutsipa weKugadzirwa kweSimbi neSimbi

Indasitiri yesimbi inovimba zvakanyanya nesimbi yekubatanidza kuti mabasa arambe achifamba zvakanaka. Imwe yenzira dzayo huru ndeyekuisa zvidhinha zvemagetsi. Zvidhinha zvechinyakare zvemagnesium zvaimboshandiswa, asi simba rekubatanidza rine magnesium rave kutonga. Rinogona kusungirirwa zvakasimba mumadziro emukati mechoto, zvichiita kuti pave nechikamu chakakora uye chisina musono. Chikamu ichi chinodzivirira kupisa kwakanyanya (kusvika 1,800°C) uye ngura yesimbi yakanyungudutswa.

Simba rekugadzira simbi rinoshandawo se "muchengeti" akavimbika wemidziyo yesimbi (migero inotakura simbi yakanyungudutswa). Simbi yakanyungudutswa inokwesha zvikuru uye inoparadza, asi simba rekugadzira midziyo yesimbi, ine alumina yakawanda, inogara yakasimba. Inodzivirira kubuda kwemvura nekutsemuka, zvichiita kuti simbi irambe ichiyerera nguva dzose. Pasina iyo, kugadziriswa kwemidziyo nguva nenguva kwaizomisa kugadzirwa uye kuwedzera mari.

2. Indasitiri yeMakemikoro: Kuve nechokwadi chekugadzikana mukuita kwakanyanya

Muindasitiri yemakemikari, uko maovheni anoshandiswa pakuita zvinhu zvakaita sekugadzira makemikari uye kupisa zvinhu, ramming mass ishamwari yakavimbika. Ndiyo chinhu chakakosha mukuvaka ovheni. Pakuvaka ovheni dzemakemikari, ramming mass inoshandiswa kurongedza mukati memukati. Hunhu hwayo hwakanaka hwekudzivirira kupisa hunochengetedza tembiricha yemukati meovheni yakagadzikana, ukuwo kuramba kwayo kuparadzwa nemakemikari kunodzivirira chimiro cheovheni.
Pamusoro pezvo, kurema kwesimbi yekunyungudutsa inyanzvi yekugadzirisa zvigadziko nemadhishi. Zvigadziko (zvinoshandiswa kunyungudutsa simbi) nemadhishi (zvinoshandiswa kutakura zvinhu zvakanyungudutswa) zvinowanzova nemadhishi mushure mekushandiswa kakawanda. Panzvimbo pekutsiva (izvo zvinodhura), kurema kwesimbi yekunyungudutsa kunogona kushandiswa kuzadza madhishi. Chidzidzo chakaratidza kuti kugadzirisa chigadziko chesimbi chine kurema kwesimbi yekunyungudutsa kunoderedza mari yekutsiva ne70% uye kunowedzera hupenyu hwechigadziko ne40%.

3. Mimwe Minda Yemaindasitiri: Inoshanda Zvakasiyana-siyana

Kurema kwekugadzira hakungogumiri pakugadzira simbi nemakemikari chete—kunopenyawo mune dzimwe nzvimbo. Mumagirazi ekuchengetera, anoshandiswa kufukidza nzvimbo dzinosangana negirazi rakanyungudutswa. Girazi rakanyungudutswa rinopisa zvikuru uye rinoparadza, asi kurema kwekugadzira kwegirazi rekuchengetera (nekunge rine silica shoma) kunodzivirira kukurwa kwevhu, zvichiita kuti girazi rirambe rakafanana.

Mukugadzira simbi isina ferrous (senge kugadzirwa kwearuminiyamu nemhangura), ramming huss inowedzera kushanda kwechoto. Inodzivirira kupisa kwakanyanya uye kurwiswa kwesimbi yakanyungudutswa. Kune aluminium melting muAustralia, kuchinja kune ramming huss kwakawedzera kushanda kwechoto ne20%, sezvo kupisa kushoma kwaibuda nepajira.

4. Sei Uchifanira Kusarudza Misa Yemhando Yepamusoro Yekusimudza Mapapiro?

Kuti uwane mhedzisiro yakanaka, kusarudza huremu hwemhando yepamusoro ndicho chinhu chakakosha. Tsvaga zvigadzirwa zvakagadzirwa nezvinhu zvepamusoro-soro (senge alumina ine purity yakakura kana magnesium oxide), maitiro akasimba ekugadzira (kuona kuti zvakafanana), uye mhando dzinovimbwa dzine sevhisi yakanaka mushure mekutengesa. Mutengesi akavimbika achapawo mhinduro dzakagadzirwa zvichienderana nezvinodiwa neindasitiri yako.

Mhedziso

Simba rekugadzira zvinhu zvemhando ye "ramming mass" ringave risiri iro rinozivikanwa zvakanyanya, asi rinochinja-chinja maindasitiri anopisa zvakanyanya. Kubva pakugadzira simbi kusvika kumakemikari, uye magirazi kusvika kusimbi dzisina feri, rinovimbisa kugara kwenguva refu, rinoderedza mitengo, uye rinowedzera kushanda zvakanaka. Sezvo maindasitiri achichinja, simba rekugadzira zvinhu zvemhando ye "ramming mass" richaramba richichinja—zvichiita kuti rive mari yenguva refu kune chero bhizinesi. Wagadzirira kuvandudza mashandiro ako eindasitiri here? Sarudza simba rekugadzira zvinhu zvemhando yepamusoro nhasi!
