Quenching da tempering tsari na 316L bakin karfe tsiri

Quenching da tempering su ne tsarin kula da zafi da ake amfani da su don inganta kayan aikin injiniya na kayan, ciki har da bakin karfe kamar 316L. Ana amfani da waɗannan hanyoyin sau da yawa don haɓaka taurin, ƙarfi, da tauri yayin kiyaye juriyar lalata. Anan ga yadda za'a iya amfani da tsarin quenching da tempering zuwa 316L bakin karfe tsiri:

1. Annealing (ZABI): Kafin quenching da fushi, za ka iya zabar anneal bakin karfe 316L don sauƙaƙa damuwa na ciki da tabbatar da kaddarorin iri. Annealing ya haɗa da dumama karfe zuwa takamaiman zafin jiki (yawanci a kusa da 1900F ko 1040C) sannan a sanyaya shi a hankali cikin tsari mai sarrafawa.
2. Quenching: Zafi 316L bakin karfe tsiri zuwa zafin jiki na austenitic, yawanci a kusa da 1850-2050 ° F (1010-1120 ° C) dangane da takamaiman abun da ke ciki.
   Rike ƙarfe a wannan zafin jiki na ɗan lokaci don tabbatar da dumama iri ɗaya.
   Kashe karfe cikin sauri ta hanyar nutsar da shi a cikin matsakaiciyar kashewa, yawanci mai, ruwa, ko maganin polymer. Zaɓin matsakaicin quenching ya dogara da abubuwan da ake so da kauri na tsiri.
   Quenching da sauri yana kwantar da ƙarfe, yana sa shi ya canza daga austenite zuwa mafi wuya, mafi raunin lokaci, yawanci martensite.
3. Tempering: Bayan quenching, karfe zai zama da wuya sosai amma gaggautsa. Don inganta taurin da rage raguwa, karfe yana da zafi.
   Yanayin zafin jiki yana da mahimmanci kuma yawanci yana cikin kewayon 300-1100°F (150-590°C), dangane da abubuwan da ake so. Madaidaicin zafin jiki ya dogara da takamaiman aikace-aikacen.
   Riƙe ƙarfe a zafin jiki na ɗan lokaci, wanda zai iya bambanta dangane da abubuwan da ake so.
   Tsarin zafin jiki yana rage taurin karfe yayin inganta taurinsa da ductility. Mafi girma da zafin jiki, da taushi da ƙarin ductile karfe zai zama.
4. Cooling: Bayan zafin jiki, ba da damar 316L bakin karfe tsiri don yin sanyi ta halitta a cikin iska ko a ƙimar sarrafawa zuwa zafin jiki.
5. Gwaji da Kula da Inganci: Yana da mahimmanci a yi gwaje-gwajen inji da na ƙarfe akan tsiri da aka kashe da zafin don tabbatar da ya dace da ƙayyadaddun bayanai da kaddarorin da ake so. Waɗannan gwaje-gwajen na iya haɗawa da gwajin taurin, gwajin juzu'i, gwajin tasiri, da kuma nazarin tsarin ƙananan ƙwayoyin cuta. Ya kamata a ƙayyade takamaiman ma'auni na quenching da zafin jiki, kamar yanayin zafi da tsawon lokaci, bisa ga kaddarorin da ake buƙata don aikace-aikacen kuma yana iya buƙatar gwaji da gwaji. Daidaitaccen sarrafa dumama, riƙewa, quenching, da matakan zafin jiki yana da mahimmanci don cimma ma'aunin da ake so na taurin, ƙarfi, da tauri yayin kiyaye juriya na lalata a cikin 316L bakin karfe. Bugu da ƙari, ya kamata a ɗauki matakan tsaro yayin aiki tare da matakai masu zafi da masu kashe wuta.
