Nzvimbo Yekushanda yeKirni yeGirazi

Nzvimbo yekushanda mukirni yegirazi yakanyanya kuomarara, uye kukuvara kwejira rekirni risingashande kunonyanya kukanganiswa nezvinhu zvinotevera.

(1) Kukukurwa kwemakemikari

Girazi rine huwandu hwakakura hwezvikamu zveSiO2, saka rine acidic yemakemikari. Kana zvinhu zvemuchoto zvikabatana nemvura yegirazi, kana pasi pekushanda kwechikamu chegasi-mvura, kana pasi pekushanda kweupfu neguruva zvakapararira, ngura yemakemikari inokuvadza zvakanyanya. Kunyanya pasi neparutivi pemadziro ebhavhu, uko girazi rinoputika rinokanganiswa nekukura kwenguva refu, kukuvara kwemakemikari kunotonyanya kuipa. Zvidhinha zvechecker zve regenerator zvinoshanda pasi pekupisa kwakanyanya kwefume, gasi neguruva, kukuvara kwemakemikari kwakasimbawo. Naizvozvo, pakusarudza zvinhu zvinodzivisa, kuramba ngura ndicho chinhu chakakosha kufungwa nezvacho. Chidziviriro chebhavhu chakanyungudutswa chinodzivisa uye chinodzivisa madziro eparutivi chinofanira kunge chiri acid. Mumakore achangopfuura, zvidhinha zve AZS series zvakasanganiswa ndiyo sarudzo yakanakisa yezvikamu zvakakosha zvebhavhu rakanyungudutswa, zvakaita sezvidhinha zve zirconia mullite nezvidhinha zve zirconium corundum, pamusoro pezvo, zvidhinha zve silicon zvemhando yepamusoro zvinoshandiswawo.

Tichifunga nezvechimiro chakakosha chechitofu chegirazi, madziro ebhavhu nepasi pacho zvakagadzirwa nezvidhinha zvikuru zvinoramba kushanda panzvimbo pezvidhinha zvidiki, saka chinhu chacho chinonyanya kugadzirwa nesimbi yakasanganiswa.

(2) Kukwesha nemidziyo
Kukwesha nekushandisa michina kunonyanya kukwesha nekushandisa magirazi akanyunguduka, senge pahuro yemoto wechikamu chekunyunguduka. Chechipiri kukwesha nekushandisa michina, senge panopinda zvinhu. Saka, zvinhu zvinoramba zvichishandiswa pano zvinofanira kunge zvine simba guru rekushandisa michina uye zvinodzivirira kukwesha zvakanaka.

(3) Kupisa kwakanyanya
Tembiricha yekushanda kwegirazi muchoto inosvika 1600 °C, uye kuchinja-chinja kwetembiricha yechikamu chimwe nechimwe kuri pakati pe100 ne200 °C. Zvinofanirawo kucherechedzwa kuti jira rechoto rinoshanda mumamiriro ekunze anodziya kwenguva refu. Zvinhu zvinodzivirira girazi muchoto zvinofanira kuramba zvichikura, uye hazvifanirwe kusvibisa mvura yegirazi.
