Yakadzika chromium magnesia chrome zvidhinha zve sement kilns uye yakananga yakasungwa magnesia chrome zvidhinha

Magnesia chrome zvidhinha zvigadzirwa zvinokanganisa zvine magnesium oxide (MgO) uye chromium trioxide (Cr2O3) sezvinhu zvikuru, uye periclase uye spinel semakemikari makuru. Rudzi urwu rwezvidhina rine kukwirira kukuru kwekushisa, simba rakakwira rekushisa, yakasimba kushinga kune alkaline slag kukukurwa, kwakanakisa kupisa kwakasimba, uye kumwe kuchinjika kune acid slag. Huru mbichana zvigadzirwa zvekugadzira magnesia-chrome zvidhinha sintered magnesia uye chromite. Iko kuchena kwemagnesia mbishi zvigadzirwa kunofanirwa kuve kwakakwira sezvinobvira. Zvinodikanwa zvemakemikari akaumbwa echromite ndeaya: Cr2O3: 30 ~ 45%, CaO: ≤1.0 ~ 1.5%.

Magnesium chrome zvidhinha zvinonyanya kushandiswa mu metallurgia indasitiri, senge kuvakwa kwenzvimbo dzakavhurika dzechoto mato, magetsi emoto turu, kunze-kwe-choto yekuchenesa mavira uye akasiyana asiri esimbi simbi yekuyera mavira. Iyo yakanyanya-tembiricha chikamu cheiyo yevira madziro emagetsi-emagetsi emagetsi emagetsi inogadzirwa neakasanganiswa-kukanda magnesia-chrome zvidhinha, iyo yakakwira-kugumisira nzvimbo yeiyo yekuchenesa choto kunze kwevira rakagadzirwa nezvinhu zvekugadzira, uye iyo kukwirira-kukwira kwenzvimbo yeasina-ferrous simbi inopenya yekunyungudutsa choto inogadzirwa neakasanganiswa-yakakandwa magnesia-chrome zvidhinha uye zvigadzirwa zvekugadzira. Yakagadzirwa nemagnesia chrome zvidhinha. Uye zvakare, magnesia-chrome zvidhinha zvinoshandiswa zvakare munzvimbo inotsva yesimendi rotary kilns uye inogadzirisazve magirazi kilns.

Iwo epanyama uye emakemikari zvimiro zveakaderera chromium magnesia chrome zvidhinha uye akananga akasungwa magnesia chrome zvidhinha zvinoshandiswa musimenti kilns ndeaya anotevera:

Zvinoenderana nekuumbwa uye mashandiro emhando mbiri idzi dzezvidhinha, maindasitiri akasiyana uye mapoinzi anofanirwa kutariswa mukuita kwekushandisa mumasimoni kilns.

1. Kukomberedza zvidhinha

Zvakananga zvakasanganiswa nemagnesia-chrome zvidhinha pazasi pe1500, shanduko yemutsara inogona kusvika + 0.2% -0.8%. Kune mahwendefa esimbi kana madhaka anonamira mudenderedzwa redhina kuti apinze izvi zvakawedzerwa chinhu chakabatana, saka nzira yekuveza yakachena isina mahwendefa esimbi kana madhaka emoto haigone kushandiswa. , Uye yakaderera chromium magnesia chrome zvidhinha zvinopihwa nekadhibhodhi pamutsago, iyo yekupedzisira ine kadhibhodhi ukobvu hwe2mm

2. Kubikira huni

Zvakananga zvakasungwa magnesia-chrome zvidhinha zvinonyanya kunetseka nekunetsekana kwemukati kwechidhinha chakakonzerwa nekupisa uye ellipticity yemuviri wevira, saka kudzora kwakasimba kunodiwa.
Zvakananga zvakasungwa magnesia-chrome zvidhinha zvine yakawanda chromium, ine yakaderera kuramba kune alkali ngura mune iyo oxidizing mhepo, uye zvisungo zvekubatanidza zvechromium-ine chikamu zvinoparara. Zvidhinha zviri nyore kukuvadza uye zvinokonzeresa kusvibiswa kwakakomba nharaunda.

3. Kuramba kudzikisira mhepo

Kuita kumwe chete uku kunoitika mumhando mbiri dzezvidhinha munzvimbo inoderera, iyo inoparadza chikamu chekubatanidza uye pakupedzisira inotungamira mukukuvadza kwezvidhinha. Kubatana kwakananga kwemagnesia-chrome zvidhinha kuchanyanya kukanganiswa.

4.Kufurira pakuumbwa kweganda remoto

Dura rakapfuma muC4AF richaumbwa pakati peiyo yepasi-chromium uye yakakwirira-iron magnesia-chrome yezvidhinha uye iyo clinker, saka iko kweganda rekuita kuri nani. Iko kushanda kweganda remoto kwakanyatso kubatanidzwa nemagnesia-chrome zvidhinha zvinosiyana nekuumbwa kwechidhina. Kana ganda remoto rajairika Kana kugadzirwa nekugadzirisa kuri kwakanaka, kudziya kwenzvimbo yezvidhinha pasi peganda reganda kunodonha zvakanyanya, uye hazvina kukosha zvakanyanya kusanganisa zvakanakira simba rakakwira rekushisa remagnesia chrome zvidhinha.
Ikozvino kwabuda akati wandei pasi chrome magnesia-chrome zvidhinha, chrome isina yemahara zvidhinha, iyo yekugadzira inokwana inosvika ku6000-10000T / h yePC kiln, iyo yakanyanya tembiricha uye yekupisa yekuvhunduka kuramba kwakanyanya zvakanyanya, vakagadzira inoenderana tip Spar inosanganiswa nechena yakachena chromium-isina yakasarudzika magnesium inonyanya kushandiswa munzvimbo yekushandurwa kwenzvimbo yesimendi kilns.
