Dab tsi yog cov rooj siv feem ntau hauv kev tsim cov txheej txheem induction cua sov?
What are the commonly used tables in the formulation of induction heat treatment processes?
Commonly used tables in the formulation of induction heat treatment processes are:
(1) Daim npav daim npav Qhov no yog ib daim ntawv rau cov neeg siv khoom siv los sim cov lus qhia tshwj xeeb, saib lub rooj.
Part Number los yog ib feem npe:
Fais fab mov thiab quenching tshuab naj npawb los yog npe:
zaus Hz; voltage V; zog kW
| Quenching ib feem: | |||
| Transformation ratio ntawm quenching transformer | |||
| Anti-tam sim no coil tig | Coupling (zeeg) | ||
| Fais fab tuag/kvar | Cov lus teb (scale) | – | |
| Sensor tooj | Sensor tooj | ||
| Generator tsis-load voltage / V | Anode tsis-load voltage / kV | ||
| Generator load voltage / V | Load voltage / kV | ||
| Generator tam sim no / A | Anode tam sim no / A | ||
| Lub zog muaj zog / kW | Rooj vag tam sim no / A | ||
| Fais fab kis tau | Lub zog hluav taws xob / kV | ||
| Lub sijhawm cua sov / s lossis kW • s | Lub sijhawm cua sov / s lossis kW • s | ||
| Pre-txias lub sij hawm / s | Pre-txias lub sij hawm / s | ||
| Lub sijhawm txias / s | Lub sijhawm txias / s | ||
| Dej txau siab / MPa | Dej txau siab / MPa | ||
| Quenching txias nruab nrab kub / tsis muaj | Quenching txias nruab nrab kub / Y | ||
| Loj feem ntawm quenching txias nruab nrab lub npe (%) | Loj feem ntawm quenching txias nruab nrab lub npe (%) | ||
| Hloov ceev / (mm / s) | Hloov ceev / (mm / s) | ||
Tom qab tus kws ua haujlwm ua haujlwm debug qhov ntu, nkag mus rau qhov tsis sib xws hauv cov lus no, thiab tseem nkag mus rau cov teeb meem pom thaum lub sijhawm debugging specification hauv lub rooj. Kab laug sab yog siv rau qhov nruab nrab zaus, thiab kab sab xis yog siv rau qhov siab zaus.
(2) Induction tshav kub kho qhov chaw tsom xam thiab tshuaj xyuas daim npav (saib Daim duab 3-10) Qhov no yog cov lus qhia dav dav uas suav nrog cov khoom siv tshuaj ntsuam xyuas, qhov tawv tawv, qhov tob ntawm cov txheej tawv tawv, thiab cov txiaj ntsig soj ntsuam macro thiab microstructure. Raws li cov txiaj ntsig thiab kev txiav txim siab ntawm lub rooj no, tus neeg ua haujlwm craftsman tuaj yeem tsim cov yam ntxwv ntawm daim npav khoom siv tes ua.
Table 3-10 Kev soj ntsuam thiab tshuaj xyuas daim npav ntawm induction cua sov kho qhov chaw
| 1. Cov khoom muaj pes tsawg leeg (cov qhab nia loj) | (%) | ||||||||
| C | Mn | Si | S | P | Cr | Ni | W | V | Mo |
HRC qhov chaw hardness:
Hardened txheej qhov tob / hli
(Kho qhov nkhaus ntawm seem hardness)
Macroscopic hardened txheej faib:
(Duab los yog kos duab rau nplai)
Microstructure thiab qib:
xeem tau:
(3) Induction cua sov txheej txheem daim npav feem ntau muab faib ua ob nplooj ntawv, thawj nplooj ntawv suav nrog cov khoom siv, kev xav tau, schematic daim duab, cov txheej txheem thiab cov txheej txheem, thiab lwm yam. Cov txheej txheem feem ntau suav nrog induction hardening, intermediate inspection, tempering, tshuaj xyuas (hardness. , zoo li, kev soj ntsuam sib nqus, kev tshuaj xyuas qhov chaw tsis tu ncua ntawm cov qauv metallographic, thiab lwm yam). Yog hais tias cov khoom yuav tsum tau ncaj nraim tom qab quenching, cov txheej txheem straightening tuaj yeem suav nrog hauv daim npav no.
Cov ntsiab lus tseem ceeb ntawm nplooj ntawv thib ob yog cov txheej txheem txheej txheem. Cov lus no tuaj yeem siv rau qhov siab thiab nruab nrab zaus. Cov ntsiab lus tseem ceeb ntawm cov txheej txheem tsis zoo ib yam li cov ntawv teev cia.
1) Nws yuav tsum tau muab sau tseg tias daim duab schematic ntawm ib feem tseem ceeb heev. Lub quenched ib feem tuaj yeem kos ib feem nrog rau kev siv cov khoom kos duab, thiab qhov loj me yuav tsum tau ntxiv nrog cov nyiaj sib tsoo, vim tias cov khoom kos duab yog cov khoom tiav lawm, thiab daim npav txheej txheem yog cov txheej txheem loj.
2) Lub hardened cheeb tsam yuav tsum tau cim nrog qhov ntev thiab kam rau ua.
3) Cov khoom kuaj xyuas yuav tsum muaj feem pua, xws li 100%, 5%, thiab lwm yam.
4) Tus txheeb ze txoj hauj lwm ntawm lub workpiece thiab lub voj voog zoo yuav tsum tau cim ntawm ib sab ntawm daim duab kos duab, thiab qhov txheeb ze ntawm qhov pib thiab qhov xaus ntawm qhov scanning hardened yuav tsum tau cim.
