Yawancin sassa na inji suna aiki a ƙarƙashin maye gurbin da tasirin tasiri kamar torsion da lankwasawa, kuma saman saman su yana ɗaukar damuwa fiye da ainihin; A cikin yanayi na gogayya, saman Layer yana ƙarewa koyaushe. Sabili da haka, an gabatar da buƙatun da ake buƙata don ƙarfafa Layer na ƙirƙira a gaba, wanda ke nufin cewa saman yana da ƙarfi mai ƙarfi, tauri da juriya.
Surface zafi jiyya na forgings bangare ne mai tsari da cewa kawai shafi zafi magani a saman na workpiece canza tsarin da kaddarorin. Yawancin lokaci, saman yana da tsayi mai tsayi da juriya, yayin da ainihin har yanzu yana kula da isasshen filastik da tauri. A cikin samarwa, an fara zaɓar karfe tare da wani abun da ke ciki don tabbatar da cewa kayan aikin injiniya na ainihin sun cika buƙatun, sannan ana amfani da hanyoyin kula da zafin jiki don ƙarfafa saman saman don saduwa da buƙatun aikin. Maganin zafin jiki ya kasu kashi biyu: quenching surface da kuma saman sinadarai maganin zafi.
Fuskar bangon bangon ƙirƙira. The surface quenching na forgings sassa ne mai zafi magani Hanyar cewa da sauri heats saman workpiece zuwa quenching zazzabi, sa'an nan da sauri cooling saukar, kawai kyale saman Layer ya sami quenched tsarin, yayin da core har yanzu kula da pre-quenched tsarin. . Yawanci ana amfani da su sune dumama dumama quenching da harshen wuta quenching. Sama quenching ne gaba ɗaya amfani da matsakaici carbon karfe da matsakaici carbon gami karfe forgings.
Induction dumama quenching yana amfani da ƙa'idar shigar da wutar lantarki don haifar da manyan igiyoyin ruwa a saman kayan aikin ta hanyar canjin halin yanzu, yana haifar da zafi da sauri na ƙirƙira yayin da ainihin ke kusan rashin zafi.
Halayen induction dumama quenching: bayan quenching, da martensite hatsi suna mai ladabi, da surface taurin ne 2-3 HRC sama da na talakawa quenching. Akwai gagarumin raguwar damuwa na matsa lamba akan saman Layer, wanda ke taimakawa wajen inganta ƙarfin gajiya; Ba mai yiwuwa ga nakasawa da oxidative decarburization; Sauƙi don cimma aikin injiniya da sarrafa kansa, dacewa da samar da taro. Bayan shigar da dumama quenching, domin rage quenching danniya da brittleness, a low zafin jiki zafi a 170-200 ℃ ake bukata.
quenching na harshen wuta hanya ce ta tsari wacce ke amfani da harshen iskar oxygen acetylene konewar iskar gas (har zuwa 3100-3200 ° C) don ɗora zafi da sauri sama da yanayin canjin lokaci, sannan quenching da sanyaya.
Nan da nan gudanar da ƙananan zafin jiki bayan quenching, ko amfani da zafi na cikin gida na ƙirƙira don zafin kai. Wannan hanya na iya samun zurfin quenching na 2-6 mm, tare da kayan aiki mai sauƙi da ƙananan farashi, wanda ya dace da yanki ɗaya ko ƙananan samar da tsari.
