Coefficient ya kukula kwamwatsatanetsatane zitsulo chitoliro
Yang'anani njira angagwiritsidwe ntchito mu ng'anjo annealing madzi sopo misozi aliyense mpata olowa, kuona ngati kuthamanga gasi;malo omwe mpweya umatha kulowa mu chubu cha ng'anjo ndikuyika chubu m'malo mwake, zisindikizo za malowa zimakhala pachiwopsezo chotha kung'ambika, Yang'anani nthawi zonse kusintha.Anaperekedwa pamaso pa mpukutu kupanga mwatsatanetsatane zitsulo pretreatment ndondomeko chiwembu;kusanthula kutentha kwa normalizing, kugwira nthawi ndi kuzirala chikoka cha zopangira chubu microstructure ndi mawotchi katundu;kudziwa ochiritsira normalizing ndondomeko mwatsatanetsatane zitsulo machubu: Kutentha kutentha (890 ± 10) ℃, mpweya kuzirala atagwira 6min interspersed.Ndondomeko yokhazikika yokhazikika imatha kuthetsedwanso mwatsatanetsatane zitsulo za Widmanstaten kuti zifanane ndi mphamvu zokolola komanso mphamvu zamakokedwe ndizokwanira zokolola chiŵerengero σS / bσ≤0.78, elongation 5δ≥30%, ndikusintha kwambiri mawonekedwe ozizira kupewa mng'alu wozizira.Coefficient yowonjezera imatha kuwonetsedwa ndi voliyumu kapena kutalika kumawonetsedwa molingana ndi kutalika.
Kachulukidwe ndi kachulukidwe kakang'ono ka zinthu pa voliyumu ya chinthucho, unit ndi kg / m3 kapena 1b / in3.Kupanikizika kotsalira kotsalira makamaka kuchokera kupsinjika kotsalira komwe kumapangidwa mu chipangizocho panthawi yowotcherera.Pakali pano, ambiri ntchito uinjiniya annealing mankhwala kuthetsa nkhawa yotsalira pambuyo kuwotcherera kuzirala, ndi kuziziritsa pambuyo kuwotcherera yotsalira kupsyinjika ndi njira yofunika, njira imeneyi ndi kuwononga mphamvu ndi zosavuta kukhala ndi kuwotcherera yotsalira kupsyinjika.Chithandizo cha kutentha kwa post weld ndi ukadaulo watsopano wochotsa kupsinjika kotsalira.Pamaso kuwotcherera mwatsatanetsatane zitsulo chitoliro ndi preheated ndi kutentha mankhwala kutentha ndi kuwotcherera ndondomeko kuwotcherera anapitiriza Kutentha kusunga kutentha, ntchito kuwotcherera watha thonje kutchinjiriza kutchinjiriza kuloledwa kuziziritsa pang`onopang`ono.Kuzimitsa chitsulo chitoliro kuonjezera mphamvu ndi kuuma, koma kuchepetsa plasticity awo.Zimitseni zowumitsa zomwe zimagwiritsidwa ntchito m'madzi, mafuta, mchere ndi alkali solution ndi zina zotero.Adzakhala ndi chitsulo chosasunthika chowumitsa chitsulo chokhazikika chomwe chimatenthedwanso mpaka kutentha kwina, ndiyeno njira ina yozizirira yotchedwa tempering.Cholinga chake ndikuchotsa kupsinjika kwamkati komwe kumapangidwa ndi kuzimitsa kuti muchepetse kuuma ndi brittleness, kuti mupeze zofunikira zamakina.Kutentha kumasonyeza kutentha kwakukulu, kutentha ndi kutentha kochepa kumapangitsa magawo atatu.Multi-kuzimitsa ndi kutentha, normalizing ntchito molumikizana.Pambuyo quenching ndi tempering quenching njira amatchedwa quenching.
