Yuav ua li cas hom ntawm nruam casting tshuab yog siv los faib lub nruam casting tshuab?
1) Vertical nruam casting tshuab, ntsug dabtsi yog khoov nruam casting tshuab, nkhaus nruam casting tshuab, elliptical nruam casting tshuab thiab kab rov tav nruam casting tshuab.
2) A, ntsug nruam casting tshuab: qhov zoo: lub tshuab casting plhaub txias yog ib yam, thiab tsis raug khoov ncaj, yog li nws tsis tsim nyog los tsim cov kab nrib pleb sab hauv thiab saum npoo, uas yog qhov tsim nyog rau kev suav nrog ntab; Qhov tsis zoo: cov cuab yeej siv siab siab, kev ua haujlwm tsis yooj yim, cov nqi peev siab, cov khoom siv tu thiab kev sib tsoo yog qhov nyuaj, qhov seem seem thiab qhov ntev thiab rub nrawm yog txwv, thiab cov slab muaj lub siab zoo li qub vim cov hlau molten. , thiab slab femoral deformation yog qhov tseem ceeb dua.
B, elliptical nruam casting tshuab: qhov zoo: qhov siab yog txo qis heev piv nrog arc, qhov zoo li qub siab ntawm cov hlau molten yog tsawg, tus nqi ntawm cov strands ntawm cov casting dawb paug yog me me, qhov nruab nrab segregation ntawm lub sab hauv tawg yog txhim kho, thiab kev nqis peev txuag 20% –30% (cov duab tshwj xeeb arc). Disadvantages: Cov inclusions nyob rau hauv lub molten steel nyob rau hauv lub crystallizer yuav luag tsis muaj floating, yog li cov kev cai rau molten steel yog nruj me ntsis.
- Kab rov tav nruam casting tshuab: Qhov zoo: Nws yog cov cuab yeej qis tshaj qhov siab, qhov thib ob oxidation ntawm molten steel, qhov zoo ntawm slab yog txhim kho, nws tsis cuam tshuam los ntawm dabtsi yog khoov thiab straightening, nws yog qhov zoo los tiv thaiv cov kab nrib pleb, cov khoom siv tu yooj yim, thiab kev sib tsoo yog yooj yim; Kev sib cais ntawm lub pob thiab cov crystallizer kuj tseem kim, thiab lubrication ntawm crystallizer thiab cam khwb cia slab yog nyuaj. Lub crystallizer tsis vibrate thaum lub sij hawm kos duab, thiab yog haum rau me me blanks, ntau yam castings, billet ntawm 200 mm los yog tsawg dua, round billet, tshwj xeeb hlau.
D, nkhaus nruam casting tshuab: muab faib ua ib qho taw tes ncaj arc nruam casting tshuab, multi-point straightening arc nruam casting tshuab, ncaj siv lead ua pwm nruam casting tshuab.
a) Ib qho taw qhia ncaj ncaj arc nruam casting tshuab: Qhov zoo: qhov siab yog qis dua li hom ntsug thiab ntsug dabtsi yog khoov hom, yog li cov cuab yeej yog lub teeb hauv qhov hnyav, tsis tshua muaj nqi peev, yooj yim hauv kev teeb tsa thiab kev saib xyuas, thiab lub siab zoo li qub. ntawm cov hlau molten ntawm lub casting dawb paug yog me me, uas tuaj yeem txo qhov ua rau sab hauv thiab kev sib cais los ntawm lub plab femoral yog qhov zoo los txhim kho qhov ceev ntawm cov casting thiab txhim kho qhov zoo ntawm cov slab. Disadvantages: Thaum lub sij hawm solidification txheej txheem ntawm molten steel, non-metallic inclusions muaj ib tug nyiam nyob rau hauv lub arc, uas ua rau nyob rau hauv unevenly faib ntawm cov khib nyiab nyob rau hauv lub casting dawb paug.
b) Multi-point straightening arc nruam casting tshuab: Qhov zoo: Thaum cov khoom-kua interface deformation tus nqi txo, cov tub ntxhais ua kua yog straightened yam tsis muaj cov kab nrib pleb, uas muaj txiaj ntsig zoo rau kev rub nrawm.
c) Ncaj ncaj crystallizer nkhaus nruam casting tshuab Qhov Zoo: Nws muaj qhov zoo ntawm hom ntsug, uas yog qhov zoo rau lub ntab ntawm cov khoom loj thiab qhov nruab nrab faib ntawm cov khoom siv hauv cov hlau. Nws yog siab tshaj qhov ntsug dabtsi yog khoov qhov siab thiab tsis tshua muaj nqi tsim kho. Disadvantages: Lub plhaub sab nrauv ntawm lub casting dawb paug yog stretched, thiab ob-theem cheeb tsam yog ib qho yooj yim ua rau tawg tsis xws luag. Cov txheej txheem cov cuab yeej yog qhov nyuaj, thiab nws nyuaj rau kev kho thiab kho.
