Gwiritsani ntchito cholembera (dinani kuti muwerenge zambiri)

1.Check the resistance of silicon carbide heating element in the batch yomweyo musanatsegule kulongedza, ikani kulimbana kwapafupi kwambiri mgawo lomwelo, zomwe zimapangitsa kutentha kwa ng'anjo kukhala yunifolomu yambiri, kukana komwe tidzalemba kudera lozizira.

2.Chifukwa cha silicon carbide ndichinthu chovuta komanso chosavuta, osayesa kukonza mukachiyika, chikhale chosunthika momwe zingathere, chimatanthauza kuchipanga chosunthika ndipo chimatha kutuluka mukamayika. Silicon carbide Kutentha element akhoza kukhazikitsa ndi dangle kapena mosabisa.

3.Chotengera cha silicon carbide element element chimagwiritsa ntchito thyristor control, kotero mphamvu imasinthika, mphamvu yoyeserera ya wolamulirayo iyenera kukhala yopitilira 2-3 kuposa mphamvu yamoto yamotoyo, motero kukulitsa moyo wa silicon carbide m'njira yabwinoko.

4. Sankhani njira yolumikizira yolumikizira kutengera kukula ndi kulimbikira kwa kutentha kwa silicon carbide.

5.Chinthu chatsopano chotentha cha silicon carbide chikuyenera kukulitsa mphamvu pang'onopang'ono pakuwotcha, zimapangitsa kusiyana pakati pa kutentha kwa silicon carbide ndi kutentha kwa ng'anjo kumakhala kocheperako, motero kutalikitsa moyo wa silicon carbide element element life. After kukhazikitsa silicon carbide heating element, Kutumiza mphamvu motere: Choyamba ikani mphamvu ku 30% -40% yamphamvu yopangira kuti ichepetse mphindi 20 -40 mphindi, kenako idakwera mpaka 60% -70% yamphamvu yopanga kuti isakanize 20 mphindi -30 mphindi, pambuyo pake kutentha kwa silicon carbide Kutentha kwa zinthu ndi ng'anjo ndiyabwino, kenako kuwonjezera mphamvu pang'onopang'ono, zolembedwa zamagetsi komanso zaposachedwa mpaka kutentha kumafikira kutentha komwe kumafunidwa, izi ndizomwe zimagwiritsa ntchito magetsi komanso magetsi a silicon carbide element element, Mkati mwamtunduwu Ikhoza kukhazikitsidwa pakuwongolera kutentha kokha, pomwe kulimbikira kunayamba kukulitsa mphamvu yamagetsi yoyenera, kuti silicon carbide Kutentha element kuti maintai n mphamvu yokhazikika

6. Ng'anjo ikakonzeka, pamene mpweya wa silicon carbide umatitenthe ife ndikuyika tebulo motere: Mphamvu yamagetsi ikagwiritsidwa ntchito kuyamba kugwiritsa ntchito 40% mphamvu yamphamvu yense, kutentha mphindi 20, kenako kuwonjezera kutentha mpaka kutentha komwe mukufuna kwa mphindi 10 mpaka 30, kenako ikani nthawi yakugwirako.

7. Musangoyang'ana magetsi kapena magetsi mukamagwiritsa ntchito silicon carbide element element, chifukwa mukamagwiritsa ntchito kulimbana kumakhala kokulirapo pang'onopang'ono (magetsi azikula ndipo pano azikhala ocheperako), mphamvu yolowetsa nthawi zonse, ndiye kutentha kumakhala kosasintha.

8.Ngati zinthu zotentha za silicon carbide zawonongeka mutagwiritsa ntchito miyezi, musasinthe zatsopano, musinthe zinthu zotentha za silicon carbide, ndichifukwa choti kukana kudzakhala kokulirapo mukamagwiritsa ntchito, kukana kwatsopano kudzakula khalani ochepa kwambiri, ngati mutagwiritsa ntchito chatsopano kutentha kumakhala kosiyana ndi zinthu zotentha za silicon carbide, kotero mutha kusintha zomwe zagwiritsidwa ntchito, zomwe zingapangitse kulimbana kwa zinthu zotenthetsera kufupi. ngati mulibe zotenthetsera zinthu, chonde sinthani zonse zotenthetsera kukhala zatsopano, ndiye zomwe mungagwiritse ntchito mukazisintha mukafuna.

9. Kukaniza kudzakhala kokulirapo mukamagwiritsa ntchito chinthu chotenthetsera, ngati kutentha sikungakhutitsidwe ngati magetsi afika kwambiri, chonde sinthani kulumikizana, monga kulumikizana kwamndandanda kungasinthe kufanana, kusintha kwa nyenyezi kumasintha kulumikizana ndi delta, inu iyenera kusintha kulumikizana kumadalira woyang'anira wanu.

10. Chitsulo chosakaniza ndi slag ndi zinthu zina m'ng'anjo ziyenera kutsukidwa mu nthawi, musazisunge m'ng'anjo, ngati zingalumikizane ndi zotentha kuti ziwonongeke.

11. Kugwiritsa ntchito mosalekeza kudzakhala ndi moyo wautali kuposa kugwiritsa ntchito pakanthawi kochepa.

12. Zomwe mukufuna kuti muzitenthe siziyenera kukhala ndi chinyezi chambiri, kuti mupewe kutentha, musayang'ane ndi zinthu zamchere.

13. Kutentha kwa silicon carbide Kutentha element pamwamba sikuyenera kupitirira 1550 ℃.

Katundu wamagetsi, katundu wamankhwala (dinani kuti muwerenge zambiri)

SICTECH Silicon carbide heating element nthawi zambiri amakhala ndi makutidwe ndi okosijeni pang'onopang'ono, kapangidwe ka Silika ndi kuwonjezeka kwa kukana kwamagetsi, komwe kumatchedwa kuwonongeka pakugwiritsidwa ntchito.

SiC + 2O2 → SiO2 + CO2

Silicon carbide (SiC) imagwira ntchito ndi mpweya (O2) m'mlengalenga komanso pamwamba pazinthu zotenthetsera pang'onopang'ono ma oxide, omwe amapanga Silika (SiO2), yomwe ndi insulator, pomwe kuchuluka kwake kumawonjezeka. Izi zimapangitsa kukana kwamagetsi. Makutidwe ndi okosijeni kumachitika kutentha kumafika pa 800 ° C ndipo kumathamangitsidwa kutentha kukamakula. Kutsekemera kwachangu kumachitika koyambirira kwa ntchito, koma kuchuluka kwa makutidwe ndi okosijeni kumachepa pang'onopang'ono. Malire a moyo wautumiki akuti ndi pomwe kukana kwake kukuwonjezeka kufikira pafupifupi katatu kukana koyamba. (Moyo wa LD ndi LS umakhala mpaka kukana kufika nthawi 2 kuposa mtengo wapachiyambi). Cholinga chake ndikuti, pakukula kuwonjezeka katatu, kusiyanasiyana kwa kulimbana kwa chinthu chilichonse kumachulukirachulukira ndikufalikira kwa kutentha kwa chinthu chimodzi kumakulirakulira, kuchititsa kutentha kochepa m'chipinda chamoto.
