Pob zeb rauv txoj kev rau zus tau tej cov tsawg thiab nruab nrab Carbon Ferromanganese

(1) Pob zeb rauv hluav taws xob rauv txoj kev
Pob zeb rauv hluav taws xob rauv txoj kev yog txoj kev tseem ceeb ntawm pob zeb rauv smelting daim ntawv thov. Lub hauv paus ntsiab lus ntawm kev siv pob zeb rauv hluav taws xob rauv txoj kev yog peb lub qhov cub sib txuas.
Ua ntej, cov manganese slag los ntawm cov khoom los ntawm lub qhov cub refining yog muab tso rau hauv lub rocker, thiab tom qab ntawd cov kua manganese silicon alloy tsim los ntawm cov ntxhia tshav kub rau hauv lub rocker. Nrog rau qhov ceev ntawm 55-60r / min co rauv, lub MnO nyob rau hauv manganese slag yog txo los ntawm silicon nyob rau hauv manganese silicon alloy nyob rau hauv zoo kinetic tej yam kev mob. Tom qab cov tshuaj tiv thaiv, cov tshuaj tshav kub tso tawm los ntawm kev hloov ua kom ntseeg tau tias cov smelting yog nqa tawm ib txwm.

Cov tshuaj tiv thaiv kab mob sib npaug yog:
2MnO + Si = = 2 Mn + SiO2. Txhawm rau slag MnO depletion rau cov kev cai lij choj tom qab muab pov tseg, cov khib nyiab pov tseg yog quenched los ntawm dej thiab siv los tsim cov khoom siv hauv tsev. Ua kua alloy rau refining rauv kom txog rau thaum refining ntawm tsim nyog mesocarbon manganese hlau; Cov tshuaj tiv thaiv nyob rau hauv lub refining rauv yog tib yam li electrosilicon thermal txoj kev.


(2) Silicon Thermal Method ntawm Pob Zeb Rauv
Kev tsim cov pa roj carbon tsawg ferromanganese los ntawm silicon thermal txoj kev ntawm rocker rauv yog pioneered los ntawm Japanese Shizhima hlau alloy thiab muab tso rau hauv kev tsim khoom. Nws yog thawj zaug preheated nyob rau hauv lub ncej rau 600 ~ 800 ° C ntawm manganese ore thiab txiv qaub nyob rau hauv lub rocker, Ces cov kua manganese alloy tsim los ntawm cov ntxhia tshav kub rauv, pib lub rocker, rocking ceev ntawm 1 ~ 65r / min, Thaum kev khiav hauj lwm, qhov ceev yog maj mam nce nyob ntawm qhov kev siv ntawm cov tshuaj tiv thaiv nyob rau hauv lub cub tawg.


Lub ntsiab txo cov tshuaj tiv thaiv manganese oxides yog: 2Mn2O3 + Si = = = 4MnO + SiO2 和2MnO + Si = = = 2MnO + SiO2
Feem ntau ntawm cov tshuaj tiv thaiv desilicon yog ua nyob rau hauv tus txheej txheem ntawm kub-rau-manganese silicon alloy, thiab ib feem me me yog ua los ntawm tag nrho cov agitation ntawm lub rocker. Lub silicon nyob rau hauv cov hlau yog yeej oxidized, cov tshuaj tiv thaiv zoo li ntsiag to thaum lub qhov cub tawg, lub ncuav slag condensate tom qab crushing rau siv nyob rau hauv lub cub tawg smelting manganese silicon alloy. Ua kua alloy casting tom qab phaj tooj zoo stacking.
