Lub luag haujlwm tseem ceeb
1. Lead lub billet: Thaum lub sij hawm nruam casting txheej txheem, molten steel yog poured rau hauv cov pwm tooj liab, thiab nrog rau kev co thiab txias ntawm cov pwm tooj liab, cov hlau maj mam solidifies rau hauv ib lub billet. dummy bar taub hau yog nyob rau hauv qab cov pwm tooj liab, thiab nws yog lub luag hauj lwm rau kev coj thiab kev txhawb nqa lub billet uas tau pib solidified, thiab xyuas kom meej tias nws nkag mus rau hauv lub thib ob cua txias cheeb tsam yam tsis muaj teeb meem.
2. Kev tswj cov duab billet: Cov qauv tsim thiab cov duab ntawm lub taub hau dummy bar muaj qhov cuam tshuam ncaj qha rau cov duab thiab qhov zoo ntawm lub billet. Kev tsim kom zoo ntawm lub taub hau dummy bar tuaj yeem pab tswj tus nqi cua txias thiab cov duab ntawm lub billet, yog li txhim kho qhov zoo thiab tawm los ntawm billet.
Txoj cai ntawm kev ua haujlwm
Lub hauv paus ntsiab lus ua haujlwm ntawm lub taub hau dummy bar yog ze ze rau kev ua haujlwm tag nrho ntawm lub tshuab nruam nruam. Thaum lub sij hawm nruam casting txheej txheem, molten steel yog thawj zaug poured rau hauv cov pwm tooj liab, thiab raws li cov tooj liab pwm vibrates, cov hlau pib solidify. Lub sijhawm no, lub taub hau dummy bar yog nyob rau hauv qab cov pwm tooj liab thiab yog ze rau qhov pib solidified billet. Raws li lub billet loj tuaj, lub taub hau dummy bar rub lub billet cia los ntawm qhov chaw txias txias thiab thaum kawg mus rau qhov chaw txiav. Thoob plaws hauv cov txheej txheem, lub taub hau Dummy bar tsis tsuas yog muab traction rau downward zog ntawm lub billet, tab sis kuj pab tswj cov duab ntawm lub billet thiab cov cua txias npaum li cas los ntawm nws tshwj xeeb tsim.
Kev siv tsis tau
1. Cov yam ntxwv tsis zoo
| Parameter | Hom ntau yam / piav qhia | ua rau |
| Lub taub hau zoo li | Swallowtail, rectangular, cone (hloov mus rau qhov sib txawv crystallization hauv qab duab) | Xyuas kom meej nrog lub crystallization foob kom tiv thaiv steel to |
| seem seem | -Billet / rectangular billet: 200200mm ~ 600600mm | Muab cov seem casting los xyuas kom meej qhov pib solidification uniformity |
| -Slab: dav 1000 ~ 2500mm, thickness 150 ~ 400mm | ||
| ntev | 300 ~ 800mm (txog rau crystallization ntev thiab nqus tau nrawm) | Muab cov lus qhia kom txaus kom ruaj khov ntawm lub plhaub tsim |
| Tone Angle | 1℃~ 3℃(feem ntau siv) | Nws yog ib qho yooj yim kom cais tawm ntawm lub pob zeb casting thiab txo adhesion |
| Qhov loj ntawm graphite inlay block | Lub thickness yog 20 ~ 50mm, thiab qhov dav tso nyiaj rau 60% ~ 80% ntawm lub taub hau dav | Txo cov kev sib txhuam coefficient nrog lub siab kub casting los tiv thaiv adhesion |
2. Cov kev xaiv xaiv
| Hom cam khwb cia hlau | Pom zoo lub taub hau tsis |
| Me me square blank | Lub taub hau loj 200200mm, cov khoom siv 42 CrMo + Al ₂ O ₃ txheej, dej txias txaus 5m³ / h |
| Loj seem slab | Lub taub hau dav ntawm 2000mm, cov khoom siv H13 + WC txheej, dej txias matrix channel tsim, dej ntws ntawm 15m³ / h |
3. Kev tu tsis tu ncua
| Parameter | Cov qauv kev saib xyuas |
| Graphite block hnav | Hloov rau thickness<10mm (50~200 times) |
| Txheej peeling cheeb tsam | >10% deg cheeb tsam |
| Bolt pretension attenuation | Monthly testing with torque wrench, attenuation>15% xav kom rov kho dua |
| Txias dej channel scaling | Annual pickling and scaling (treated immediately when flow rate drops> 20%) |
Peb lub tuam txhab muaj ntau xyoo dhau los ntawm kev tsim khoom thiab kev lag luam ntawm dummy bar hau, nrog cov kws tshaj lij cov neeg ua haujlwm, raws li tus neeg xav tau kev pab ntawm cov neeg siv khoom, ntau lawm thiab ua. Cov ntaub ntawv parameter saum toj no tuaj yeem siv rau kev siv, yog tias koj muaj kev xav tau tshwj xeeb, thov hu rau peb.
