Steel smelting kom nceferromolybdenumtawm los thiab txo cov nqi tsim khoom
Tam sim no, nyob rau hauv cov txheej txheem smelting ntawm molybdenum-muaj hlau, ferromolybdenum yog ntxiv rau lub converter ua ke nrog cov seem hlau nyob rau hauv seem hopper. Thaum lub sij hawm hloov tshuab tshuab, cov txiaj ntsig ntawm ferromolybdenum kuj qis, tsuas yog 80% -85%, uas ua rau cov nqi smelting zoo heev. Tsis muaj ib txoj hauv kev los ua kom cov qoob loo ntawm ferromolybdenum thaum lub sij hawm smelting.
Ib txoj kev siv hlau smelting uas txo cov nqi tsim khoom thiab ua kom cov qoob loo ntawm ferromolybdenum. Txoj kev pub mis ntawm ferromolybdenum yog hloov los ntawm converter pub rau kev pub mis los ntawm qib siab silo thaum lub sij hawm tapping, uas daws qhov teeb meem ntawm cov molybdenum uas tsis tshua muaj yield thaum smelting molybdenum-muaj hlau. teeb meem, thiab yuav ua li cas los txhim kho molybdenum yield, stabilize txheej txheem tswj, thiab txo cov nqi thaum smelting high-zoo steel kom tau raws li cov kev cai ntau lawm.
Cov kev daws teeb meem tau txais los daws cov teeb meem technical ntawm ferromolybdenum yog:
1. Hloov txoj kev pub mis ntawm ferromolybdenum los ntawm converter pub rau high-theem silo pub thaum tapping;
2. Ua kom muaj kev ua haujlwm ntawm cov cib ua pa hauv qab ntawm lub ladle kom ntseeg tau tias huab cua nkag; Lub granularity ntawm ferromolybdenum yog tswj los ntawm 15 hli -30 hli rau lumped ferromolybdenum; tapping kub yog tswj ntawm 1680-1710 degree ;
3. Thaum tapping, argon gas ntws tus nqi cua tshuab nyob rau hauv qab ntawm lub ladle yog tswj ntawm 6-7NL/( daim iav) kom paub meej tias cov hlau cov kua theem yog tig ;
4. Thaum cov hlau tapping tus nqi nce mus txog 1/2, ntxiv alloy thiab ferromolybdenum nyob rau hauv qhov kev txiav txim ntawm AlFe-MnFe-MoFe; lub slag thickness yog 30-60 hli, tswj tus nqi slag nyob rau hauv lub converter;
5. Tom qab khob, ntxiv 0.4- Aluminium particles ntawm 0.6kg/t steel yog tso rau ntawm slag nto ntawm lub ladle.
Qhov zoo ntawm cov tshiab ferromolybdenum ntxiv txoj kev ua tau zoo daws qhov teeb meem ntawm molybdenum yield tsawg thaum smelting molybdenum-muaj hlau. Molybdenum tawm los ntawm 80% -85% mus rau ntau tshaj 95%, uas tuaj yeem ua tiav cov khoom lag luam ruaj khov thiab txo cov nqi smelting zoo heev.
