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. Kudzera njira, chinthu chomalizidwa chimapangidwa ndi kutsika kwamphamvu ndi kuwongolera mphero yolimba, yomwe ingawonetsetse kuti zitsulo zogulirazi zimagundidwa pamtunda wa 730 ~ 760 ~ Zoyenera kupeza mitengo yabwino, njirayi sioyenera kupanga mizere yopanga. 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 zimakhala zazitali, makamaka pakupanga mphamvu ya zidayi ndikuwonjezera mtengo wopangidwa ndi njirayi ndi zochulukirapo. Kuchuluka kwa kuchuluka, ndizovuta kutsimikizira kuchuluka kwa magwiridwe antchito.
Kukhazikitsa kwaukadaulo:
Zopangira zomwe zikuwoneka kuti zimapereka njira yopangira zitsulo zotentha, makamaka njira yopanga nkhono zogulira zosenda zapamwamba ~ hrb400e, zomwe zimathetsa ndalama zomwe zalembedwazi.
Dongosolo laukadaulo wa zopangidwa ndi izi:
Njira yopanga zitsulo zotentha zosewerera, zomwe zimanenedwa za nthiti za nthiti ndi φ10mm, zozizira - zozizira - zozizira - zosemerera - kuzizira - kuzizira kwambiri; the chemical composition mass percentage of steel is c=0.20%~0.25%, si=0.40%~0.50%, mn=1.40%~1.60%, p≤0.045%, s ≤0.045%, v=0.015%~0.020%, the rest are Fe and unavoidable impurity elements; 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 kupangidwa ndizotere: Powonjezera zochepa v pofuna kusintha, v ndi c mawonekedwe carbider, ndikupanga gawo la mpweya wolimbitsa thupi. 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 yoyendetsa bwino ndi: kutentha kotuluka: 1080 ~ 1120 ℃, Kutembenuza Kutentha Kwambiri: 850 ~ 85 ~ 660 ~ 80 ~ 650 ~ 620 ~ 620 ~ 620 ~ 82 ~ Nthawi Pachikuto cha kutentha ndi 45 ~ 55s, ndipo chimazizira 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.
