LC Ferro Manganese Ua li cas?

Tsawg-Carbon Ferro Manganese yog dab tsi?

Tsawg-carbon ferro manganese, luv luv li LC FeMn, yog manganese- hlau alloy nyob rau hauv uas cov ntsiab lus carbon yog txhob txwm tuav qis dua 0.5 feem pua. Cov qib lag luam feem ntau muaj 78 mus rau 88 feem pua ​​​​ntawm manganese, nrog qhov sib npaug yog hlau thiab me me ntawm silicon, phosphorus thiab sulfur. Vim tias nws qhia txog manganese yam tsis muaj cov pa roj carbon, LC FeMn yog cov khoom siv manganese nyiam rau cov hlau tsis muaj steel, alloy steels thiab qis- carbon steel qib uas cov pa roj carbon tswj yog qhov tseem ceeb. Nws txhim kho lub zog, hardness thiab hnav tsis kam thaum khaws cia ductility thiab weldability hauv cov hlau tiav.

Raw Materials thiab Feedstock Npaj

Kev tsim khoom ntawm LC FeMn pib nrog manganese- cov khoom noj nplua nuj. Manganese ore muaj 30 mus rau 50 feem pua ​​​​ntawm manganese, sintered manganese ore, thiab tau txais txiaj ntsig manganese concentrates yog lub ntsiab manganese. Cov ore yog crushed, sib tov thiab tshuaj ntsuam rau ib tug uniform loj kom tus nqi reacts tusyees nyob rau hauv lub cub tawg. Txiv qaub los yog dolomite yog ntxiv raws li flux los tsim ib qho yooj yim slag, uas tiv thaiv cov hlau los ntawm re-oxidation thiab pab tshem tawm phosphorus thiab sulfur. Tus neeg sawv cev txo qis yog silicon-cov kabmob alloy, xws li ferrosilicon lossis siliconanganese, vim tias silicon tuaj yeem txo cov manganese oxide los ntawm slag yam tsis tau qhia cov pa roj carbon rau hauv cov hlau kawg.

Main Production Routes rau LC FeMn

Silicothermic Refining

Silicothermic refining yog txoj kev siv dav tshaj plaws rau qis -carbon ferromanganese. Manganese ore, flux thiab silicon- nplua nuj reductant raug them rau hauv lub tshuab hluav taws xob refining rauv thiab yaj ntawm qhov kub ntawm qhov kub ntawm 1400 txog 1500 degrees Celsius. Silicon nyob rau hauv lub reductant reacts nrog manganese oxide nyob rau hauv lub molten slag, txo nws mus rau metallic manganese uas qhia rau cov hlau da dej. Vim hais tias cov reductant muaj me me los yog tsis muaj cov pa roj carbon, cov hlau ua los ntawm txoj kev no muaj cov ntsiab lus tsis tshua muaj carbon. Cov txheej txheem yog nqa tawm nyob rau hauv cov theem, nrog ib tug thib ob slagging kauj ruam kom rov qab residual manganese los ntawm thawj slag thiab kom nruj qhov kawg muaj pes tsawg leeg.

Kev kho decarburization

Txoj kev thib ob pib los ntawm qhov siab dua -carbon manganese yaj, feem ntau nruab nrab -carbon ferromanganese lossis kev sib xyaw ntawm siab -carbon ferromanganese nrog manganese ore, thiab tshem tawm cov pa roj carbon monoxide los ntawm lub tshuab nqus tsev oxygen decarburization. Cov pa roj carbon monoxide yog oxidized rau cov pa roj carbon monoxide thiab tawm hauv da dej, txo cov pa roj carbon ntsiab lus kom qis dua 0.5 feem pua. Vim tias manganese oxidizes yooj yim dua li hlau, cov txheej txheem yuav tsum tau ua tib zoo tswj nrog ib qho yooj yim slag thiab tswj kub kom tsis txhob manganese poob qis. Txoj kev no tau txais kev pom zoo thaum cov neeg tsim khoom xav tau pib los ntawm qis dua - tus nqi siab - carbon feedstock thiab thaum lub tshuab hluav taws xob muaj nyob.

Hom Composition thiab Qib Parameters

Cov kev txwv tseeb ua raws li lub teb chaws lossis thoob ntiaj teb tus qauv thiab tus neeg yuav khoom specification. Siab dua - qib manganese siab dua 85 feem pua ​​​​Mn hais kom tus nqi them vim tias lawv xav tau ntau dua - qib ore thiab kev ua kom zoo dua slag.

Kev Tswj Xyuas Zoo thiab Kev Tshawb Fawb Hauv Kev Tsim Khoom

Txhim khu kev qha LC FeMn ntau lawm nyob ntawm kev tswj ntawm txhua kauj ruam. Txhua qhov cua sov yog kuaj tom qab ua kom zoo thiab tshuaj xyuas rau manganese, carbon, silicon, phosphorus thiab sulfur. Cov hlau yog ces muab pov rau hauv ingots los yog granulated, crushed thiab soj ntsuam mus rau qhov kev txiav txim loj ntau yam, thiab soj ntsuam rau loj tis, bulk ntom thiab internal soundness. Daim ntawv pov thawj ntawm kev tshuaj xyuas yog muab rau txhua pawg, thiab kev ywj pheej thib peb - tog tshuaj ntsuam feem ntau yog npaj ua ntej xa khoom los xyuas cov tshuaj thiab qhov loj ntawm daim ntawv cog lus.

Cov lus nug nquag

Dab tsi yog qhov txwv carbon rau qis -carbon ferro manganese?

Tsawg- carbon ferromanganese feem ntau tau teev tseg nrog cov pa roj carbon monoxide ntawm lossis qis dua 0.5 feem pua, thiab ntau qib hwm tau tuav txog 0.2 txog 0.4 feem pua ​​​​siab tshaj.

Vim li cas cov ntsiab lus qis carbon tseem ceeb hauv steelmaking?

Adding manganese without carbon allows steelmakers to hit target manganese levels while keeping carbon within specification, which is essential for stainless steels, low-carbon strip grades and other products where excess carbon would cause hardening, brittleness or rejection.

Cov ntaub ntawv dab tsi yog siv los tsim LC FeMn?

Cov khoom siv tseem ceeb yog manganese ore lossis sinter, txiv qaub flux, thiab silicon -cov kabmob reductant xws li ferrosilicon lossis siliconanganese. Rau txoj kev decarburization, siab dua -carbon ferromanganese yog siv los ua qhov pib yaj.

Dab tsi yog qhov txawv ntawm silicothermic refining thiab oxygen decarburization?

Silicothermic refining siv silicon los txo cov manganese oxide thiab yeej tsis qhia cov pa roj carbon, thaum decarburization tshem tawm cov pa roj carbon monoxide los ntawm cov yaj uas twb muaj lawm nrog oxygen lossis lub tshuab nqus tsev. Ob leeg tuaj yeem ncav cuag cov pa roj carbon qis dua 0.5 feem pua, tab sis lawv txawv ntawm cov khoom noj, hom rauv thiab kev siv hluav taws xob.

LC FeMn muab qhov loj npaum li cas?

Qhov loj me me yog 10 mus rau 50 hli thiab 10 mus rau 100 hli lumps, nrog cov feem me me thiab kev txiav txim siab muaj rau cored hlau lossis cov tshuab them nyiaj tshwj xeeb.

Qhov zoo ntawm LC FeMn txheeb xyuas li cas?

Kev ua tau zoo raug txheeb xyuas los ntawm ib- tshuaj ntsuam xyuas cua sov, daim ntawv pov thawj ntawm kev tshuaj xyuas rau txhua pawg, kev tshuaj xyuas qhov loj me, thiab xaiv thib peb- kev tshuaj ntsuam xyuas ua ntej xa khoom.
