SmCo Disc Magnet

Samarium Cobalt Magnet

Cov hlau nplaum samarium cobalt yog ib hom hlau nplaum uas tsis tshua muaj hauv ntiaj teb. Nws yog tsim los ntawm kev sib xyaw ua ke ntawm samarium, cobalt, thiab lwm yam tsis tshua muaj lub ntiaj teb hlau los ntawm cov txheej txheem ntawm proportioning, melting rau hauv ib qho alloy, crushing, nias, thiab sintering. Cov khoom siv no muaj cov khoom siv hluav taws xob sib nqus siab thiab qhov kub tsis tshua muaj coefficient. Qhov siab tshaj plaws ua haujlwm kub tuaj yeem ncav cuag 350 degree, thiab tsis muaj kev txwv rau qhov kub tsis zoo. Thaum ua haujlwm kub siab tshaj 180 degree, nws cov khoom siv hluav taws xob siab tshaj plaws (BHmax), kev sib koom ua ke, qhov kub thiab txias, thiab tshuaj lom neeg ruaj khov tag nrho cov khoom siv hlau nplaum ruaj khov NdFeB. Nws kuj muaj zog tiv thaiv corrosion thiab oxidation, ua rau nws dav siv nyob rau hauv aerospace, tiv thaiv lub teb chaws, microwave li, kev sib txuas lus, cov cuab yeej kho mob, cov twj paj nruag, meters, ntau yam sib nqus kis tau tus mob li, sensors, sib nqus processors, motors, magnetic cranes, thiab lwm yam.

Qhov siab tshaj plaws magnetic zog khoom (BHmax) ntawm samarium cobalt hlau nplaum nyob ntawm 16 MGOe mus rau 32 MGOe, nrog rau kev txwv ntawm 34 MGOe. Muaj ob qhov sib xyaw ua ke rau samarium cobalt hlau nplaum: 1: 5 thiab 2: 17 (samarium atoms rau cobalt atoms).

SmCo Disc Magnet Processing txheej txheem

Cov txheej txheem ntau lawm suav nrog: batching → smelting los tsim ingots → hmoov ua → nias → sintering thiab tempering → sib nqus → sib tsoo → precision processing → tiav cov khoom.

Cov alloys no feem ntau yog machined nyob rau hauv lub xeev unmagnetized. Samarium cobalt yog ua tiav siv cov kev sib tsoo ntub dej (nrog dej-txias rau cov cua sov dissipation) thiab pob zeb diamond sib tsoo log. Cov txheej txheem no yog tsim nyog thaum drilling qhov lossis hais txog lwm yam kev ua haujlwm. Kev sib tsoo pov tseg yuav tsum tsis txhob raug tso cai kom qhuav tag, vim samarium cobalt muaj qhov taw tes qis. Lub txim me me, xws li ib qho tsim los ntawm hluav taws xob zoo li qub, tuaj yeem ua rau nws yooj yim. Qhov tshwm sim hluav taws tuaj yeem ua rau kub siab heev thiab tswj tau yooj yim.

Kev phom sij

1. SmCo hlau nplaum yog qhov ua rau chipping, yog li cov tsom iav yuav tsum tau hnav thaum tuav lawv.
2. Tso cai rau cov hlau nplaum sib tsoo tuaj yeem ua rau lawv tawg, tsim kom muaj kev phom sij.
3. Samarium cobalt hlau nplaum yog tsim los ntawm cov txheej txheem sintering, uas tuaj yeem ua rau tawg sab hauv. Cov hlau nplaum no tsis muaj kev ncaj ncees thiab tsuas yog ua haujlwm los tsim cov hlau nplaum. Yog li ntawd, tshwj xeeb mechanical systems yuav tsum tau tsim los xyuas kom meej cov neeg kho tshuab kev cia siab rau tag nrho cov system.

Yam ntxwv

1. Siab coercivity heev.
2. Kev ruaj ntseg kub zoo heev (qhov siab tshaj plaws ua haujlwm kub ntawm 250 degree mus rau 550 degree, thiab Curie kub li ntawm 700 degree txog 800 degree).
3. Tus nqi kim thiab raug rau tus nqi hloov pauv (lub khw cobalt yog tus nqi-rhiab heev).
