Titanium slag ntau lawm technology
Cov khoom siv raw rau titanium slag ntau lawm
Titanium slag yog tau los ntawm ilmenite concentrates. Ilmenite yog cov ntxhia ntuj uas muaj txog li 52.8% titanium raws li titanium dioxide.
Ilmenite yog ib lub koom haum ntawm titanium oxide nrog hlau. Yog li ntawd, thawj theem ntawm kev tsim khoom yog txhawm rau cais cov titanium dioxide los ntawm cov hlau oxides. Ilmenite concentrate yog txo nyob rau hauv ore-thermal furnaces (OTF) nyob rau hauv lub xub ntiag ntawm carbon-muaj reductant (ntoo charcoal, anthracite, coke) kom ua tiav qhov no.
Dab tsi yog Txoj Kev ntawm Titanium Slag Production
Kev ua haujlwm thev naus laus zis rau kev tsim cov titanium slag
Ib qho kev niaj hnub, txhim kho thev naus laus zis rau kev tsim cov titanium slag los ntawm ib theem txheej txheem yog npaj. Cov tshuab no yog npaj txhij rau kev siv.
Cov txheej txheem ntawm titanium slag ntau lawm yog cov txheej txheem ntawm smelting ilmenite mloog zoo nyob rau hauv arc ore-thermal furnaces (OTF) nyob rau hauv ib tug semi-kaw hom nrog kev siv cov hmoov sib tov kom tau titanium slag ntawm ib tug teev cov ntsiab lus ntawm hlau oxide, raws li zoo raws li txuam hlau.
Cov khoom tseem ceeb tshaj plaws ntawm titanium slags, uas txiav txim siab txo cov smelting txheej txheem thiab muaj peev xwm cais cov hlau thiab slag thiab lawv tapping los ntawm lub cub tawg, yog kev ntseeg siab, viscosity, thiab hluav taws xob conductivity.
Tau txais lawv los ntawm cov txheej txheem ib ntus ib ntus suav nrog cov haujlwm hauv qab no:
Kev thauj mus los, xa khoom, thiab khaws cia cov khoom siv raw;
Kev npaj thiab kev them nqi ntawm cov khoom sib tov, muaj ilmenite concentrate, txo tus neeg sawv cev, thiab plua plav ntes tau hauv cyclones, mus rau hauv OTF;
Kev txo qis ntawm smelting ntawm qhov sib tov thiab tau txais cov txheej txheem yaj ntawm slag thiab cov hlau txuam hauv OTF;
Ladle pouring slag thiab txuam hlau;
Ingot casting;
Ingot txias;
Sib tsoo thiab sib nqus sib cais ntawm titanium slag;
Desulfurization, alloying, thiab carbonization ntawm cov hlau txuam;
Ingot ncuav;
Kev xa khoom ntawm titanium slag thiab cov hlau txuas rau cov neeg siv khoom;
Recycling ntawm khib nyiab zog.
Txheej txheem khiav daim duab ntawm titanium slag smelting txheej txheem
Los ntawm kev thauj khoom hoppers, ilmenite concentrate thiab reductant yog cais pub rau dosing hoppers (txoj hauj lwm 2-4) los ntawm ib tug system ntawm siv conveyors (txoj hauj lwm 1). Cheebtsam ntawm tus nqi yog dosed los ntawm dosing hoppers nyob rau hauv xam kom muaj nuj nqis rau hauv ib tug ladle (txoj hauj lwm 5) muab tso rau ib tug trolley ntawm teev (txoj hauj lwm 15).
Filling furnace charge hoppers (txoj hauj lwm 61-6) thiab reductant hoppers (txoj hauj lwm 77-12), siv rau kev hloov slag, yog nqa tawm los ntawm ladles (txoj hauj lwm 5), uas yog thauj siv lub overhead fais crane (txoj hauj lwm 14).
Them lub qhov cub hluav taws xob ore-thermal (OTF) tshwm sim los ntawm lub qhov cub hluav taws xob los ntawm kev them nyiaj chute. Plua plav, ntes nyob rau hauv cyclones ntawm cov txheej txheem GCP ntawm OTF, yog pub rau hauv lub cub tawg nrog tus nqi.
Ib qho chaw tom qab hluav taws xob yog muab rau tom qab qhov hluav taws xob cov tshuaj tiv thaiv (pos. 101-3). Cua yog nkag mus rau lub afterburner chamber los ntawm cov kiv cua (pos. 111-3).
Cov txheej txheem roj rho tawm los ntawm OTF yog ua los ntawm cov kav dej. Gases raug ntxuav los ntawm hmoov av hauv cyclones (pos. 12) thiab lub hnab lim (pos. 13).
