40Cr yotentha yozungulira zitsulo zozungulira

40Cr alloy structural steel ili ndi mphamvu zowonjezereka, zokolola mphamvu ndi kuuma kuposa No. 40Cr ndi sing'anga mpweya modulated chitsulo, ozizira mutu kufa chitsulo. Chitsulocho ndi chamtengo wapatali komanso chosavuta kukonza. Pambuyo pa chithandizo choyenera cha kutentha, kulimba kwina, pulasitiki ndi kukana kuvala kungapezeke. Normalizing imatha kulimbikitsa spheroidization ya kapangidwe kake ndikuwongolera magwiridwe antchito opanda kanthu ndi kuuma kochepera 160HBS. Kutentha pa kutentha kwa 550 ~ 570 ℃, chitsulo ali bwino mabuku katundu makina. Kuuma kwa chitsulo ichi ndikwambiri kuposa chitsulo cha 45, ndipo ndichoyenera kuchiza zowumitsa pamwamba monga kuzimitsa pafupipafupi komanso kuzimitsa moto. Pambuyo kuzimitsa ndi kutentha, chitsulo cha 40Cr chimagwiritsidwa ntchito popanga zida zamakina pansi pa katundu wapakatikati komanso liwiro lapakati, monga ziwongolero zowongolera galimoto, mazenera am'mbuyo ndi magiya, mitsinje, nyongolotsi, ma spline shafts, manja apamwamba pazida zamakina, etc.; pambuyo quenching ndi Pambuyo tempering pa sing'anga kutentha, ntchito kupanga mbali kuti kunyamula katundu mkulu, zotsatira ndi sing'anga liwiro ntchito, monga magiya, spindles, mafuta mpope rotors, slider, makolala, etc.; pambuyo kuzimitsa ndi kutentha otsika kutentha, amagwiritsidwa ntchito popanga zigawo zomwe zimanyamula katundu wolemera ndi wochepa mphamvu Ndipo mbali zokhala ndi kukana kuvala ndi makulidwe olimba pamtanda pansi pa 25mm, monga mphutsi, zitsulo, zitsulo, makola, ndi zina zotero; pambuyo kuzimitsa ndi kutentha ndi pamwamba-pafupipafupi pamwamba quenching, iwo ntchito kutulutsa mkulu pamwamba kuuma ndi kuvala kukana. Zigawo zomwe zimakhudzidwa kwambiri, monga magiya, manja, ma shafts, ma shafts, ma crankshafts, spindles, mapini, ndodo zolumikizira, zomangira, mtedza, ma valve olowera, ndi zina zambiri. monga magiya ndi ma shaft okhala ndi ma diameter akulu komanso kulimba kwa kutentha kochepa.

Kutentha mankhwala Zogwirizana

• Zowonjezera za 40CR Alloy structural steel

Kutenthetsa pang'onopang'ono mpaka 850 ℃ ndikulola nthawi zokwanira, lolani chitsulo chitenthedwe bwino, Kenako kuziziritsa pang'onopang'ono mung'anjo. Chitsulo cha aloyi cha 40CR chidzapeza MAX 250 HB (kuuma kwa Brinell).

• Kuwumitsa kwa 40CR Alloy structural chitsulo

Kutenthetsa pang'onopang'ono mpaka 880-920 ° C, Pambuyo pakuwuka kokwanira pa kutentha uku muzimitsa mafuta. Kupsa mtima pamene zida zifika kutentha kwa chipinda.

Mapulogalamu

Chitsulo cha GB 40CR chimagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito m'mafakitale amagalimoto ndi uinjiniya kwa okhala ndi zida ndi zida zina zotere. Zomwe zimagwiritsidwa ntchito monga matupi a valve, mapampu ndi zopangira, Shaft, katundu wochuluka wa gudumu, mabawuti, ma bawuti okhala ndi mitu iwiri, magiya, ndi zina zambiri.

Kukula kokhazikika ndi Kulekerera

Chitsulo chozungulira chozungulira: Diameter Ø 5mm - 3000mm

Chitsulo mbale: makulidwe 5mm - 3000mm x M'lifupi 100mm - 3500mm

Chitsulo Hexagonal bar: Hex 5mm - 105mm

Ma 40CR ena sanatchule kukula kwake, pls  lemberani gulu lathu lodziwa zamalonda.
