Njira Yopanga ndi njira yotentha yokhotakhota
Njira Zakumbuyo:
Pa msika wapano, hrb400e maakaunti ena ambiri. Njira yolimbitsa mtima yolimbitsa mtima ndiyo njira yayikulu yopangira HRB400E padziko lapansi. The microalloleyo ili makamaka Vadium Smoy kapena Niobium Aloy, yomwe imadya zambiri za zitsulo zambiri chaka chilichonse. Chifukwa cha zinthu zochepa zokhala ndi minerect okhala ndi vadium ndi Niobium, zomwe zimaperekedwa kwazinthu zoyatsirazi ndi zolimba. Chifukwa chake, ngati chivomerezo cha HRB400E Steel chingachepetsedwe, chimabweretsa phindu lalikulu komanso chikhalidwe.
Mwaukadaulo womwe ulipo, wa waya wopangira mavidiyo awiri popanda kuchepetsa ndi kuthira mphero nthawi zambiri amatenga zolimbitsa thupi kuti apange hrb400e, ndi misa yamafuta a vadium ndi 0.045%.
Chinese patent Cn104357747a akuwulula mtundu wa HRB400E Highd-Hil-Hield yachitsulo-chivomerezi chachitsulo ndi njira yake yopanga. Mwa njira, chinthu chomalizidwa chimapangidwa ndi kutsika kwamphamvu ndi kuwongolera mphero, komwe kungawonetsetse kuti zitsulo zogulirazizizo zimagundidwa pamtunda wa 730 ~ popanda kuchepetsa mphero. Chinese patent Cn110151516A akuwulula njira yokonzekera ya waya kwambiri ~ hrb400e cholumikizidwa. Mothandizidwa ndi mphamvu zamphamvu za zida, kugudubuza kochepa kumayamba kuchokera kutentha kutentha, ndipo kupanga popanda kuyamwa kumakwaniritsidwa. Zovuta za njirayi ndikuti zofuna za zida zamphamvu ndi zapakatikati ndizokwera kwambiri, makamaka kwa mzere wopangidwa ndi chiwongolero champhamvu, zomwe zimachepetsa moyo wa zida ndipo zimawonjezera mtengo wokonza a Zida, ndi zokolola zokolola za waya wapamwamba φ hrb400e coil yopangidwa ndi njirayi ndi oletsedwa. Kuchuluka kwa kuchuluka, ndizovuta kutsimikizira kuchuluka kwa magwiridwe antchito.
Kukhazikitsa kwaukadaulo:
Zopangira zomwe zikuwoneka kuti zimapereka njira yopangira zitsulo zotentha, makamaka njira yopanga nkhono zokhala ndi zosenda zokhala ndi ma aya kwambiri ~ HRB400 mtengo.
Dongosolo laukadaulo wa zopangidwa ndi izi:
Njira yopanga zitsulo zotentha, zomwe zimanenedwa chitsulo cha nthiti ndi ~8 ~ φ10mm, movutikira - kuzizira - kuzizira - kuzizira - kuzizira - kuzizira - Kupindika - cholumikizira cha mpweya-chodzitchinjiriza-coil-cell ozizira; Mankhwala opangidwa ndi mankhwala a chitsulo ndi C = 0.20% ~ 0.25%, ≤0.045%, v = 0,020 ~ 0.020%, Ena onse ndi a Fe ndi Zosalephera Kusalephereka; Njira zazikuluzikulu zimaphatikizapo: kutentha kwa ntchentche ndi 1070 ~ 1130 ℃, kutentha kosungunuka ndi 970 ~ 1000 ~ 10 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~ 1000 ~. 880 ℃; Kutentha 845 ~ 875 ℃; Kutentha kotsiriza kuli pansi pa kutentha kutentha kwa austetenite dera; Kuzizira mwachangu ndi faniza patebulo lozungulira mpweya, voliyumu ya mpweya ndi 100%; Kutentha kwa chivundikiro ndi 640 ~ 660 ℃, kutentha kwa chivundikiro cha kutentha ndi 600 ~ 620 ~ ndi nthawi yosungirako kutentha ndi 45s.
Mfundo yopanga: Mu kutentha kwa 840-880 ℃, mbewu za austete zimakula ndi kuphatikizika, koma kubwezeretsanso sikuchitika. Komabe, magulu osokoneza bongo amapangidwa mu mbewu ya austete, ndipo malekezero a zigawo za kusokonekera nthawi zambiri amakhala m'malire a tirigu, ndipo palinso magulu osokoneza bongo ngati malire a tirigu kuti aletse mbewu zazikuluzikulu za austete. Pa kusintha kwa austetete ku Ferrite, malire am'mimba ambiri ndi malo owoneka a tirigu. Kutentha kochepa kwambiri mu mphesa kumachepetsa mphamvu yogubuduza ndi mphero yogundana ndi mphero yoyendayenda ndipo imatha kupirira nthawi zonse za zida.
Zopindulitsa za kupangidwazi ndizotere: Powonjezera pang'ono v pofuna kusintha, v ndi C . Ndodo yotentha ya waya yopanga ili ndi mphamvu ya 600-700mA, mphamvu yokolola ya 420-500m, pafupifupi 2> 10%, yomwe imapangitsa kuti pakhale malire okwanira. Mphamvu zokolola zimakhala zokhazikika, ndipo kuchuluka koyenerera kuli pamwamba 99%. Kupanga mwaluso kumachepetsa vuto lomwe mphero yogundana siyovuta kuwongolera kutentha kochepa, kumachepetsa mtengo pa malo opanga sikufupika, ndipo kumabweretsa phindu lachuma kwambiri.
Njira Zatsatanetsatane
Zomwe zili momwe zilili zikufotokozedwera pansipa molumikizana ndi zokongoletsera.
Njira yopangira gulu la waya kwambiri ~ φ10mmhrb400e nkhono zophika. Njira yozungulira ndi: kutentha kotuluka: 1080 ~ 1120 ℃ Kutentha kwa 640 ~ 660 ℃, 600 ℃, 600 ~ 620 ℃ Chifukwa cha chivundikiro cha kutentha, nthawi yophimba kutentha ndi 45s, ndipo imazizira mwachilengedwe. Kuphatikizika kwa mankhwala kwa waya wa waya wa zopangira zomwe zafotokozedwapo kumawonetsedwa mu tebulo 1, ndipo makina a makina a waya wa waya wa zopangira zomwe wapezeka mu tebulo 2.
Mankhwala opangidwa (WT%) a waya waya waya
