Kev cuam tshuam ntawm Alloy Additives ntawm Kub Rise ntawm Molten Steel

 

Thaum lub sij hawm steelmaking txheej txheem, ntau yam alloy additives feem ntau ntxiv los txhim kho cov khoom ntawm hlau. Siv qhov sib ntxiv ntawm npib tsib xee (Ni) ua piv txwv, qhov tshwj xeeb kub ntawm nickel yog kwv yees li {{0}}.44 kJ/(kg· degree ). Thaum nickel alloy additives ntxiv rau cov hlau molten, thaum lub sij hawm cua sov theem, npib tsib xee yuav nqus tau ib tug loj npaum li cas ntawm tshav kub rau nws tus kheej kub nce. Piv txwv li nyob rau hauv ib tug me me hluav taws xob rauv steelmaking txheej txheem, qhov loj ntawm cov hlau molten yog 1000 kg, qhov pib kub yog 1400 degree, thiab 100 kg ntawm nickel alloy yog ntxiv. Yog tias lub zog cua sov yog 100 kW (uas yog, 100 kJ ntawm cov cua sov yog muab rau ib ob), raws li cov qauv ntsuas cua sov (, qhov twg yog qhov kub, qhov loj, yog qhov tshwj xeeb kub, thiab qhov kub hloov pauv), tsis xav txog lwm yam kub poob thiab lwm yam khoom nyob rau hauv cov hlau molten, rau cov nickel alloy, . Los ntawm kev suav, qhov kub nce ntawm cov nickel alloy yog kwv yees li . Thaum nyob rau hauv tib tus nqi ntawm cov cua sov, qhov kub nce ntawm cov hlau molten (xws li cov cua kub tshwj xeeb ntawm cov hlau tseem ceeb hauv cov hlau molten yog li ntawm 0.46 kJ / (kg· degree )) yog kwv yees li . Nws tuaj yeem pom tau tias qhov kub ntawm cov nickel alloy nce nrawm dua piv rau lub cev tseem ceeb ntawm cov hlau molten tom qab nqus cua sov, uas yuav ua rau kom qhov kub thiab txias ntawm lub cev tseem ceeb ntawm cov hlau molten, uas ua rau lub sijhawm txuas ntxiv. rau cov hlau molten kom ncav cuag lub hom phiaj kub hauv tag nrho cov txheej txheem steelmaking, yog li cuam tshuam rau kev tsim khoom.

 

Kev cuam tshuam ntawm kev sib xyaw ntawm cov khoom seem sib txawv ntawm lub sijhawm Melting

 

Thaum cov khoom siv rov ua dua tshiab muaj cov khoom sib txawv, qhov sib txawv ntawm cov cua sov tshwj xeeb yuav muaj feem cuam tshuam rau cov txheej txheem melting. Piv txwv li, rau cov khoom sib xyaw hlau uas muaj txhuas (Al) thiab hlau (Fe). Cov cua sov tshwj xeeb ntawm txhuas yog kwv yees li {{0}}.90 kJ / (kg· degree), thiab cov hlau yog li 0.46 kJ / (kg· degree ). Piv txwv li, muaj ib pawg ntawm cov khoom sib xyaw ua ke, uas feem pua ​​​​ntawm txhuas yog 30% thiab cov hlau yog 70%, nrog rau tag nrho cov hnyav ntawm 500 kg. Thaum lub sij hawm converter steelmaking txheej txheem, cua sov yog nqa tawm los ntawm sab saum toj - cua tshuab pa. Thaum cov nplaim hluav taws kub muab qee qhov cua sov, vim qhov kub tshwj xeeb ntawm txhuas, nyob rau theem pib ntawm cov cua sov, qhov kub ntawm aluminium nce qeeb tom qab nqus cua sov. Thaum qhov kub ntawm hlau nce kuj ceev thiab pib yaj. Txawm li cas los xij, raws li cov hlau melts, ib feem ntawm lub tshav kub nws absorbs yog siv rau nws tus kheej lub xeev hloov (los ntawm cov khoom mus rau cov kua), thiab lwm yam yog kis mus rau lub puag ncig unmelted aluminium. Vim tias aluminium heats qeeb qeeb thiab yuav tsum tau kub ntau kom ncav cuag nws qhov melting point, nyob rau hauv cov ntaub ntawv no, lub sij hawm melting ntawm tag nrho cov seem hlau yuav ntev dua li ntawm ib qho hlau seem hlau. Qhov no yog vim cov yam ntxwv tshwj xeeb ntawm cov cua sov ntawm aluminium, uas ua rau muaj kev hloov pauv hauv kev faib khoom thiab kev siv cov cua sov hauv cov seem hlau thiab cuam tshuam rau kev ua haujlwm melting.

Kev cuam tshuam ntawm cov cua kub tshwj xeeb ntawm cov khoom siv raw ntawm qhov kub thiab txias gradient hauv qhov cub

 

Nyob rau hauv loj converter steelmaking, ntau yam raw khoom muaj ib txhij nyob rau hauv lub cub tawg. Yog hais tias qhov sib txawv ntawm cov cua sov tshwj xeeb ntawm cov khoom siv raw yog loj, pom tseeb qhov kub thiab txias gradients yuav raug tsim. Piv txwv li, muaj ntau cov high - tshwj xeeb - tshav kub alloy raw cov ntaub ntawv (xws li tooj liab alloys, tshwj xeeb kub ntawm tooj liab yog kwv yees li 0.39 kJ / (kg· degree )) thiab zoo tib yam seem hlau nyob rau hauv lub cub tawg. Thaum lub sij hawm tshuab, cua sov yuav nyiam absorbed los ntawm lub siab - tshwj xeeb - tshav kub alloy raw cov ntaub ntawv, ua rau kub nyob rau hauv ib ncig ntawm lub cheeb tsam kuj tsis tshua muaj. Qhov no yuav ua rau muaj qhov tshwm sim ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov loj hauv lub qhov cub, cuam tshuam rau qhov sib txawv ntawm cov cua sov hauv qhov cub. Piv txwv li, nyob ze ntawm lub qhov cub phab ntsa, qhov kub ntawm qhov yuav tsum tau qis vim yog melting ntawm cov seem hlau thiab cov cua sov nqus ntawm cov ntaub ntawv raw, thaum nyob rau hauv cheeb tsam ncaj qha rhuab los ntawm nplaim taws nyob rau hauv nruab nrab ntawm lub cub tawg, qhov kub thiab txias yog feem ntau. siab. Qhov ntsuas kub ntawm qhov ntsuas kub no yuav ua rau cov txheej txheem hloov hluav taws xob tsis zoo hauv lub tshuab hluav taws xob, uas tsis tsim nyog rau kev ruaj khov ntawm cov txheej txheem steelmaking, vim tias qhov kub tsis sib xws tuaj yeem ua rau tsis sib xws ntawm cov khoom siv raw, thiab tom qab ntawd cuam tshuam rau qhov zoo ntawm cov hlau.
