Silicon manganese alloy yog ib qho kev sib xyaw ua ke deoxidizer, nws kuj yog tus neeg sawv cev txo qis. Tam sim no silicon manganese alloy rau koj los qhia silicon manganese alloy yog yuav ua li cas txo dephosphorization. Kev txo qis sab nraud thiab dephosphorization ntawm siab silicon manganese silicon alloy, siv CaSi-CaF2-Ca0 ua tus neeg sawv cev dephosphorization, nyob rau hauv cov xwm txheej ntawm cov pa oxygen tsawg heev, vam khom cov calcium hauv tus neeg sawv cev dephosphorization thiab phosphating. nyob rau hauv cov alloy Ca3P2., phosphorus nyob rau hauv lub alloy yuav raug tshem tawm, thiab cov alloying ntsiab nyob rau hauv lub alloy tsis poob. Cov khoom siv raw siv hauv smelting siab silicon manganese silicon alloy yog: manganese nplua nuj slag, silica, coke, charcoal, txiv qaub. Lub hauv paus ntsiab lus ntawm kev txo qis dephosphorization yog tias nyob rau hauv cov xwm txheej tsis tshua muaj oxygen, phosphorus hauv cov hlau raug tshem tawm los ntawm kev cia siab rau calcium hauv tus neeg sawv cev dephosphorization thiab phosphating hauv cov hlau.
Txheej txheem txheej txheem: inversion method, hmoov txau txoj kev. Yuav tsum muaj ob lub ladle A thiab B. Ladle A, tridnnC-Si alloy ua los ntawm ore-tuav rauv, ladle B yog loaded nrog dephosphorization tus neeg sawv cev. Tom qab ntawd lub ladle A yog nqa mus rau lub ladle B, lub ladle A yog qhib kom cov kua siab silicon manganese silicon alloy nyob rau hauv lub ladle A ntws mus rau ladle B nrog dephosphorization tus neeg sawv cev. Lub sijhawm no, calcium nyob rau hauv tus neeg sawv cev dephosphorization ua rau cov tshuaj tiv thaiv dephosphorization hnyav nrog phosphorus nyob rau hauv siab silicon manganese silicon alloy, thiab phosphorus nyob rau hauv cov hlau raug tshem tawm. Tus neeg sawv cev dephosphorization tau muab tso rau hauv 0.25m3 hmoov txau lub tank los ntawm cov hmoov txau. Argon roj tau siv los ua tus cab kuj los tshuaj tsuag tus neeg sawv cev dephosphorization rau hauv siab silicon manganese silicon alloy yaj los ntawm rab phom txau kom tshem tawm cov phosphorus hauv cov hlau. Thaum cov hmoov txau, lub siab ntawm cov roj txhaj tshuaj yog tswj ntawm 0.20.3MPa, lub siab ntawm cov roj fluidized tswj ntawm 0.5 ~ 0.8MPa, lub sij hawm tshuaj tsuag hmoov yog 2 ~ 3 feeb, thiab tus nqi txhaj tshuaj ntawm tus neeg sawv cev dephosphorization yog tib yam li cov txheej txheem rov qab ntim khoom. High silicon manganese silicon alloy yog ib tug txo tus neeg sawv cev rau smelting hlau manganese. Cov saum toj no yog hais txog yuav ua li cas silicon manganese alloy txo thiab dephosphorized.
