Alkalinity ntawm Silicon Manganese Alloy Slag

Thaum smelting silicon manganese alloys, silicon thiab manganese raug txo los ntawm lub xeev molten ntawm manganese silicate. MnO tau yooj yim txo, thaum SiO2 nyuaj txo. Txhawm rau kom txo qis SiO2 tag nrho thiab xyuas kom muaj cov khoom sib xyaw alloy, nws raug nquahu kom xaiv qis alkalinity slag los ntawm kev xav ntawm kev tswj cov slag muaj pes tsawg leeg, thiab qis dua alkalinity, qhov zoo dua. Tab sis thaum lub alkalinity qis dua 0.5, lub viscosity ntawm lub slag kuj siab, ua rau nws nyuaj rau tawm ntawm lub cub tawg; Thiab vim tsis zoo conductivity, nws cuam tshuam rau kev faib hluav taws xob tsis sib xws ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob, ua rau nws nyuaj kom tau txais qhov chaw dav dav. Qhov tshwm sim yog tias SiO2 tsis tuaj yeem txo qis tag nrho, thiab nws tuaj yeem ua rau muaj kev puas tsuaj rau cov cua sov. Qhov tseem ceeb cuam tshuam rau alkalinity ntawm slag yog qhov txo qis ntawm SiO2. Txoj hauv kev los txhim kho cov alkalinity ntawm slag yog kom txo qis ntawm SiO2, uas tsis tuaj yeem ua tiav los ntawm kev ntxiv CaO lossis MgO, vim tias qhov nce hauv CaO thiab MgO txwv qhov txo ntawm SiO2 thiab txo tus nqi rov qab ntawm Mn. Feem ntau, nws tsim nyog los tswj cov alkalinity ntawm slag CaO/SiO2=0.5~{11}}.7 thiab CaO plus MgO/SiO2=0.6~{15}}. 8. Lub sijhawm no, SiO2 cov ntsiab lus hauv slag yog nruab nrab ntawm 38 ~ 42 feem pua ​​​​thiab MnO cov ntsiab lus yog nyob ib ncig ntawm 10 feem pua.
