Melting ceev
Particle Size Influence: Qhov loj me me ntawm cov ntaub ntawv raw muaj qhov cuam tshuam loj heev rau qhov ceev melting. Cov ntaub ntawv nyoos nrog cov khoom me me, xws li cov khoom seem hlau lossis cov khoom siv hlau nplaum uas muaj qhov loj me ntawm 1 - 5mm, muaj thaj tsam loj dua li cov uas muaj qhov loj me me. Thaum lub sij hawm cov hlau - ua cov txheej txheem, cov cua kub hloov feem ntau tshwm sim los ntawm cov ntaub ntawv raw mus rau sab hauv. Ib cheeb tsam loj dua txhais tau tias muaj cua sov ntau dua - cov ntsiab lus nqus. Siv cov khoom siv hlau ua piv txwv, cov seem hlau nrog qhov me me tuaj yeem nqus tau cov cua sov sai dua hauv lub tshuab hloov hluav taws xob lossis lub tshuab hluav taws xob, yog li ua kom nrawm nrawm. Nyob rau hauv tib lub cua sov, lub sij hawm melting ntawm cov seem hlau nrog ib tug particle loj ntawm 1 - 5 hli yuav yog 30% - 50% luv dua li ntawm cov seem hlau nrog ib tug particle loj ntawm {{6} } hli.
Puab Influence: Cov duab ntawm cov ntaub ntawv raw kuj cuam tshuam rau lub melting ceev. Cov ntaub ntawv nyoos nrog cov duab tsis sib xws, xws li cov khoom seem hlau nrog ntau cov npoo thiab cov ces kaum los yog hauv daim ntawv nyias nyias, muaj cov cua sov loj dua nyob rau hauv qhov cub piv nrog kheej kheej lossis thaiv - zoo li cov ntaub ntawv raw. Qhov no yog vim qhov tsis sib xws - zoo li cov khoom siv raw muaj qhov sib txawv me me ntawm ib leeg thaum sib tsoo, thiab cua sov tau yooj yim dua thiab nqus tau hauv cov khoob no. Thaum lub sij hawm hluav taws xob arc rauv hlau - ua, qhov tsis sib xws - zoo li cov seem hlau tuaj yeem siv cov cua sov uas tsim los ntawm hluav taws xob arc zoo dua, ua rau cov txheej txheem melting zoo dua.

 

Tshuaj Reaction Rate
Particle Size Influence: Cov ntaub ntawv nyoos nrog cov khoom me me tuaj yeem muab cov tshuaj tiv thaiv ntau dua, yog li ua kom cov tshuaj tiv thaiv kab mob nrawm dua. Hauv cov tshuaj tiv thaiv redox thaum lub sij hawm cov hlau - ua cov txheej txheem, xws li cov hlau oxidation cov tshuaj tiv thaiv () thiab cov tshuaj tiv thaiv decarburization (), thaum cov ntaub ntawv loj me me, cov pa oxygen lossis lwm cov reactant gases tuaj yeem yooj yim dua los ntawm kev sib cuag nrog cov khoom siv raw. nto ntawm cov khoom siv raw. Piv txwv li, thaum lub sij hawm cov pa oxygen - tshuab cov txheej txheem hauv converter steel - ua, cov decarburization cov tshuaj tiv thaiv ntawm npua hlau nrog ib tug particle loj ntawm 3 - 5 hli yog li ntawm 20% - 30% sai dua li cov npua hlau nrog. ib particle loj ntawm 10 - 15mm. Qhov no yog vim hais tias cov npua hlau nrog me me particle loj muab cov pa roj carbon ntau dua - oxygen cov tshuaj tiv thaiv cuam tshuam, ua rau cov tshuaj tiv thaiv decarburization mus sai dua.
Puab Influence: Cov duab ntawm raw cov ntaub ntawv kuj cuam tshuam cov tshuaj tiv thaiv tus nqi. Cov ntaub ntawv nyoos nrog cov duab tsis yooj yim, xws li cov khoom seem hlau nrog lub qhov los yog wrinkles, yuav ua rau lub sijhawm nyob ntawm cov roj reactant ntawm lawv qhov chaw. Siv cov khoom siv ore raw li piv txwv, qee cov hlau - ore nrog cov qauv microporous tuaj yeem ua rau txo cov pa roj (xws li carbon monoxide) kom nkag mus rau hauv micropores zoo dua thiab ua rau cov hlau oxides hauv cov ore thaum lub sij hawm txo cov tshuaj tiv thaiv. Piv nrog rau cov ore nrog cov duab du, qhov txo cov tshuaj tiv thaiv ntawm cov ore no nrog cov duab nyuaj tuaj yeem nce li ntawm 15% - 20%.

Slag Formation thiab Properties
Particle Size Influence: Qhov loj me me ntawm cov khoom siv raw ua lub luag haujlwm tseem ceeb hauv kev tsim slag thiab cov khoom. Thaum lub sij hawm slag - ua txheej txheem, ib tug tsim nyog particle loj ntawm raw cov ntaub ntawv yog conducive rau tsim ntawm slag nrog zoo fluidity. Yog hais tias qhov luaj li cas ntawm slag - ua raw cov ntaub ntawv xws li txiv qaub loj heev, piv txwv li, yog hais tias lub particle loj tshaj 50 hli, nws yuav tsis tau tag nrho melted thaum lub sij hawm cov hlau - ua cov txheej txheem, uas ua rau lub non-uniform slag muaj pes tsawg leeg thiab cuam tshuam rau cov khoom. Basicity thiab fluidity ntawm slag. Txawm li cas los xij, cov txiv qaub nrog qhov me me me me (xws li 10 - 30 hli) tuaj yeem sib xyaw zoo dua nrog lwm cov slag Cheebtsam los tsim cov slag sib xws, uas yog qhov zoo rau kev tshem tawm cov impurities xws li phosphorus thiab sulfur hauv cov hlau molten.
Puab Influence: Cov duab ntawm cov ntaub ntawv raw kuj cuam tshuam rau kev tsim slag. Piv txwv li, qee cov khoom siv raw nrog cov duab elongated tuaj yeem cuam tshuam nrog ib leeg thaum lub sij hawm melting, cuam tshuam cov fluidity ntawm slag. Ntawm qhov tsis sib xws, tsis tu ncua - zoo li cov khoom siv raw yog yooj yim dua thiab sib npaug ntawm cov slag tom qab melting, uas yuav pab kom muaj kev ruaj ntseg thiab zoo lub cev ntawm cov slag. Piv txwv li, thaum ntxiv magnesia thiab lwm yam raw cov ntaub ntawv los kho cov viscosity ntawm slag, cov tsis tu ncua - zoo li tus magnesia hais yuav ua tau zoo dispersed nyob rau hauv lub slag, zoo tswj lub viscosity ntawm lub slag thiab ua rau nws ntau conducive rau impurity tshem tawm thiab molten hlau. kev tiv thaiv thaum lub sij hawm steel - ua txheej txheem.
