Zvidhinha Zvinodzora Simende yeKirni Inotenderera: Mhando uye Mashandisirwo

Makironi anotenderera esimendendiyo michina mikuru mukugadzira simende, inoshanda mumamiriro ezvinhu akaomarara—tembiricha inosvika 1450°C, kuparadzwa kwakanyanya kwemakemikari kubva kualkaline media neclinker, uye kupera kwemakemikari nguva dzose. Kusarudza zvidhinha zvinoramba zvichishanda kwakakosha pakuona kuti zvinoshanda zvakanaka, kuwedzera hupenyu hwekushanda kwechoto, uye kuderedza mari yekugadzirisa. Pazasi pane mhando huru dzezvidhinha zvinoramba zvichishanda zvakagadzirirwa machoto anotenderera esimende, chimwe nechimwe chakagadzirirwa nzvimbo dzacho dzekushanda.

Zvidhinha zveAlumina ZvakakwiriraNdiwo madhiri anonyanya kushandiswa muzvitofu zvinotenderera zvesimende. Ane alumina iri pakati pe48% kusvika 75%, anodzivirira kupisa kwakanyanya, anodzivirira kupisa zvakanyanya, uye anodzivirira kupfeka zvakanyanya. Anonyanya kushandiswa munzvimbo dzisinganyanyi kupisa dzakadai semuchina wekupinda muzvitofu, preheater, uye decomposition furnace, uko tembiricha dzinotangira pa800°C kusvika 1200°C. Kuderera kwawo kunodzivirira kupinda kwegasi rinoparadza, zvichiita kuti zvive zvakanaka kunzvimbo dzine makemikari ari pakati nepakati.

Zvidhinha zveMagnesia-Alumina SpinelZvakakosha kunzvimbo inotsva muchoto, uko tembiricha inosvika 1350°C kusvika 1450°C. Dzakagadzirwa nemagnesium oxide nealumina, dzine simba rekudzivirira kupisa uye dzinogona kugadzira jira rinodzivirira kana dzichiita clinker, zvichidzivirira kukurwa kweclinker yakanyungudutswa. Zvichienzaniswa nezvidhinha zvemagnesia-chrome, zvine simba rekudzivirira kupisa, zvichiita kuti dzive sarudzo yakasimba kune nzvimbo dzinopisa zvakanyanya.

Zvidhinha zveMagnesia-Chrome Zvakabatana ZvakanangaDzinokunda mukudzivirira ngura yemakemikari. Dzakagadzirwa ne magnesite ne chromite yemhando yepamusoro, dzakaiswa calcium pa 1750-1850°C, dzakakodzera nzvimbo inotsva uye nzvimbo yekuchinja, uko kukanganiswa kwe alkaline ne sulfate kwakanyanya. Dzinopa tembiricha inonyorovesa mutoro uye simba rakanaka remakanika, zvichiita kuti dzigare dzakagadzikana kwenguva refu munzvimbo dzakaoma.

Zvidhinha Zvisingapindi AlkaliZvakagadzirirwa muchina we tertiary air duct uye cyclone separator, uko kukanganiswa kwealkali vapor kuri pachena. Ne 25%-30% alumina uye pamusoro pe 65% silica, zvinoumba glaze layer ine viscosity high-viscosity kudzivirira kupinda kwealkali, kudzivirira kutsemuka kwezvidhinha uye kupwanyika.

Kusarudza zvidhinha zvinoramba kushanda zvakanaka zvichibva panzvimbo dzechitofu kunokanganisa zvakananga kugadzirwa zvakanaka uye mutengo. Zvidhinha zvedu zvinoramba kushanda zvakanaka zvinosangana nezvinodiwa neindasitiri, zvine mhinduro dzakagadzirirwa mhando dzakasiyana dzechitofu. Taura nesu nhasi kuti uwane zvigadzirwa zvinoramba kushanda zvakanaka zvinoderedza nguva yekushanda uye zvinosimudzira kushanda zvakanaka kwekugadzira simende.
