Njerwa za chromium magnesia chrome zotsika mtengo zazitsulo za simenti ndi njerwa zachindunji za magnesia chrome

Njerwa za Magnesia chrome ndizopanga zokhala ndi magnesium oxide (MgO) ndi chromium trioxide (Cr2O3) monga zigawo zikuluzikulu, ndi periclase ndi spinel ngati zomwe zimayambitsa mchere. Njerwa yamtunduwu imakhala ndi zotsekemera zambiri, kutentha kwambiri, kukana kwamphamvu kwamchere kwamchere, kutentha kwambiri, komanso kusinthasintha kwa asidi slag. Zipangizo zazikulu zopangira njerwa za magnesia-chrome ndi sintered magnesia ndi chromite. Kuyera kwa zopangira za magnesia kuyenera kukhala kwakukulu momwe zingathere. Zofunikira pakupanga mankhwala a chromite ndi: Cr2O3: 30 ~ 45%, CaO: ≤1.0 ~ 1.5%.

Njerwa za Magnesium chrome zimagwiritsidwa ntchito kwambiri pamakampani azitsulo, monga kumanga nsonga za ng’anjo yotseguka, nsonga zamagetsi zamagetsi, ng’anjo zowotchera m’ng’anjo ndi ziwaya zingapo zosapanga dzimbiri. Gawo lotentha kwambiri la khoma lamoto lamoto lamoto lamphamvu kwambiri limapangidwa ndi njerwa zosakanikirana ndi magnesia-chrome, malo okwera kwambiri a ng’anjo yoyenga kunja kwa ng’anjo amapangidwa ndi zinthu zopangidwa, ndipo Malo okokoloka kwambiri a ng’anjo yosakanizika ndi chitsulo amapangidwa ndi njerwa zophatikizika za magnesia-chrome ndi zida zopangira. Zapangidwa ndi njerwa za magnesia chrome. Kuphatikiza apo, njerwa za magnesia-chrome zimagwiritsidwanso ntchito m’malo oyaka simenti oyatsira ndi opangira magetsi a magalasi.

Katundu ndi mankhwala am’munsi njerwa za chromium magnesia chrome ndi njerwa zachindunji za magnesia chrome zomwe zimagwiritsidwa ntchito mu mabatani a simenti ndi izi:

Zokhudzana ndi kapangidwe kake ndi kagwiridwe kake ka mitundu iwiri ya njerwa, mafakitale osiyanasiyana ndi mfundo ziyenera kusamaliridwa pozigwiritsa ntchito mu uvuni wa simenti.

1. Njerwa

Molunjika ndi njerwa za magnesia-chrome pansi pa 1500, kusintha kwa mzere kumatha kufikira + 0.2% -0.8%. Pali mbale zachitsulo kapena matope osunthira mumizeremizere ya njerwa kuti mutenge cholumikizira chimodzi chokha, chifukwa chake njira yomanga yoyera yopanda mbale zachitsulo kapena matope amoto sangagwiritsidwe ntchito. , Ndipo njerwa za chromium magnesia chrome zotsika zimapatsidwa katoni yamakatoni, yomalizayi yokhala ndi makatoni makulidwe a 2mm

2. uvuni wophikira

Njerwa za magnesia-chrome zomwe zimakhala zolumikizidwa molunjika zimakhudzidwa kwambiri ndi kupsinjika kwamkati kwa njerwa zoyambitsidwa ndi kutentha ndi kutalika kwa thupi lamoto, motero pamafunika kuwongolera mosamalitsa.
Njerwa za magnesia-chrome zomangidwa molunjika zimakhala ndi ma chromium ambiri, zimatsutsana pang’ono ndi dzimbiri la alkali mumlengalenga, ndipo maubwenzi omangika a gawo la chromium amawonongeka. Njerwa ndizosavuta kuwononga ndikuwononga chilengedwe.

3. Kukaniza kuchepetsa mpweya

Zomwezo zimachitika pamitundu yonse ya njerwa m’malo ochepetsa, omwe amawononga gawo lolumikizana ndipo pamapeto pake amawononga njerwa. Kulumikizana kwachindunji kwa njerwa za magnesia-chrome kudzakhudzidwa kwambiri.

4. Mphamvu pakapangidwe ka khungu lamoto

Mzere wolemera mu C4AF udzapangidwa pakati pa otsika a chromium ndi mkulu-chitsulo magnesia-chrome njerwa ndi clinker, kotero khungu la uvuni ndilobwino. Magwiridwe antchito a khungu la uvuni molumikizana ndi njerwa ya magnesia-chrome imasiyanasiyana ndi kapangidwe ka njerwa. Khungu la ng’anjo likakhala labwinobwino Pomwe mapangidwe ndi kukonza kwake kuli bwino, kutentha kwa njerwa pansi pa khungu la uvuni kumatsika kwambiri, ndipo sikofunikira kwambiri kuphatikiza mwachindunji mphamvu zamphamvu zamafuta a njanji ya magnesia.
Tsopano yatuluka njerwa zingapo zotsika kwambiri za chrome magnesia-chrome, njerwa yopanda chrome, yopanga mpaka 6000-10000T / h ya uvuni wa PC, kutentha kwakukulu komanso kukana kutentha kwamphamvu ndikofunikira kwambiri, adapanga nsonga yofanana ndi Spar kuphatikiza ndi chiyero chapamwamba cha chromium chopanda magnesiamu chimagwiritsidwa ntchito posinthira ma kilns a simenti.
