Njira ya Rock Furnace Yopangira Ferromanganese Yotsika ndi Yapakatikati

(1) Njira ya ng'anjo yamagetsi ya Rock ng'anjo yamagetsi
Rock ng'anjo yamagetsi yamagetsi ndiyo njira yayikulu yosungunulira ng'anjo ya miyala. Mfundo yofunikira pakukhazikitsa njira ya ng'anjo yamagetsi ya rock ndi njira zitatu zolumikizira ng'anjo.
Choyamba, slag ya manganese yochokera ku ng'anjo yoyenga imayikidwa mu rocker, kenako madzi a manganese silicon alloy opangidwa ndi ng'anjo yotentha yamchere kulowa mu rocker. Ndi liwiro la ng'anjo ya 55-60r/min, MnO mu slag ya manganese imachepetsedwa ndi silicon mu aloyi ya silicon ya manganese pansi pazikhalidwe zabwino za kinetic. Pambuyo pazimenezi, kutentha kwa mankhwala komwe kumatulutsidwa ndi kusintha kumatsimikizira kuti smelting ikuchitika bwino.

Chemical reaction equation ndi:
2MnO + Si = = 2 Mn + SiO2. Kuti muchepetse kuchepa kwa MnO ku zomwe zanenedwa pambuyo potaya, Zinyalala zimazimitsidwa ndi madzi ndipo zimagwiritsidwa ntchito popanga zida zomangira. Aloyi yamadzimadzi yoyenga ng'anjo mpaka kuyengedwa kwa chitsulo choyenerera cha mesocarbon manganese; Zomwe zimagwiritsidwa ntchito mu ng'anjo yoyenga ndizofanana ndi njira yotentha ya electrosilicon.


(2) Njira Yotentha ya Silicon ya Ng'anjo ya Mwala
Kupanga kwa low-carbon ferromanganese ndi silicon thermal method of rocker ng'anjo kunayambika ndi Japanese Shizhima iron alloy ndikuyika mu kupanga. Imatenthedwa koyamba mumtengo mpaka 600 ~ 800 ° C wa manganese ore ndi laimu mu rocker, Kenako aloyi yamadzimadzi ya manganese yopangidwa ndi ng'anjo yotentha yamchere, kuyambira rocker, kugwedeza liwiro la 1 ~ 65r/min. ntchito, liwiro pang'onopang'ono kuchuluka malinga ndi mphamvu ya mankhwala anachita mu ng'anjo.


Kuchepetsa kwakukulu kwa manganese oxides ndi: 2Mn2O3+Si===4MnO+SiO2+2MnO+Si===2MnO+SiO2
Zambiri mwazomwe zimachitika pa desilicon zimachitika potengera aloyi ya silicon yotentha-to-manganese, ndipo gawo laling'ono limapangidwa ndi kugwedezeka kwathunthu kwa rocker. The pakachitsulo mu aloyi kwenikweni oxidized, zimene amachita amakhala bata pamene ng'anjo, ndi anatsanulira slag condensate pambuyo kuphwanya ntchito mu ng'anjo smelting manganese pakachitsulo aloyi. Madzi aloyi kuponyera pambuyo mbale nambala zabwino stacking.
