Mmene kutentha kuzimitsira pa microstructure ndi katundu wapawiri-gawo zitsulo

Monga magazi amakampani, mafuta amakhala ndi gawo lofunikira pakupanga mphamvu.Chinsinsi chochulukitsira kupanga mafuta m'dziko langa ndikuwongolera ukadaulo wakubowola mafuta.Ukadaulo wokulirapo wa chubu ndiukadaulo watsopano wofunikira wamafuta ndi gasi wopangidwa ndikupangidwa kumapeto kwa zaka za zana lapitali komanso koyambirira kwa zana lino.Ndi njira yamakina kapena ma hydraulic omwe amagwiritsidwa ntchito pansi pa nthaka kuti asunthire kondomu yowonjezera kuchokera pamwamba mpaka pansi kapena kuchokera pansi kupita pamwamba kuti apange casing Chitsulocho chimakhala chopunduka kwamuyaya kuti chikwaniritse cholinga cha chowonjezera chowonjezera pafupi ndi khoma la chitsime.Kugwiritsa ntchito ukadaulo wachubu wowonjezera kumatha kupititsa patsogolo luso laumisiri wobowola pakukula kwamafuta ndi gasi, kupulumutsa anthu, zida, nthawi ndi mtengo, ndikulimbikitsa chitukuko chaukadaulo wina wofananira.Woyang'anira uinjiniya wamafuta ku US Cook akufotokoza ukadaulo wokulirapo wa chubu ngati "kubowola mafuta "Pulojekiti yofikira mwezi" ndi imodzi mwamaukadaulo ofunikira kwambiri pamakampani amafuta ndi gasi m'zaka za zana la 21, ndipo machubu okulitsa ndi imodzi mwazinthu zofunika kwambiri. mu tekinoloji yowonjezera chubu.

Kapangidwe kazitsulo kawiri kaŵirikaŵiri kumapangidwa makamaka ndi ferrite ndi martensite, yomwe imadziwikanso kuti martensitic dual phase steel.Ili ndi mawonekedwe osatulutsa zokolola, mphamvu zokolola zochepa, kulimba kwamphamvu kwambiri komanso kufananitsa bwino kwa pulasitiki, ndipo ikuyembekezeka kukhala chinthu chomwe chimakondedwa popanga mapaipi okulitsa mumakampani amafuta.Makhalidwe abwino kwambiri a zitsulo zapawiri-gawo makamaka zimadalira morphology ndi kuchuluka kwa martensite, ndipo kutentha kozimitsa kumakhudza kwambiri kuchuluka kwa martensite muzitsulo zapawiri.

Anapanga yoyenera mankhwala zikuchokera wapawiri gawo zitsulo machubu kukula, ndipo anaphunzira zotsatira za quenching kutentha pa microstructure ndi mawotchi katundu wapawiri gawo zitsulo.Zotsatira zikuwonetsa kuti pamene kutentha kwazimayi kumawonjezeka, gawo la martensite limawonjezeka pang'onopang'ono, zomwe zimapangitsa kuwonjezeka kwa mphamvu zokolola ndi mphamvu zowonongeka.Kutentha kozimitsa ndi 820 ℃, chitsulo chapawiri-gawo lamachubu okulitsa amatha kupeza ntchito yabwino kwambiri.
