Chitsulo chotsika cha aloyi chosagwira kutentha, champhamvu kuposa chitsulo cha 12CrMo, kulimba pang'ono, pa 500-550 ° C kapena kucheperako kumakhala ndi kukana kutentha kwambiri komanso kukana makutidwe ndi okosijeni, komanso makina abwino, machinability ndi kuzizira kwapulasitiki wabwino. weldability chilungamo. Amagwiritsidwa ntchito kwambiri popanga chitoliro chachitsulo chosasunthika komanso pepala.



15CrMo Mapulogalamu:



Chitoliro chachikulu cha nthunzi cha magawo a nthunzi a 510 ° C, 530 ° C magawo a nthunzi ya boiler superheater machubu, catheters ndi mkulu-pressure nthunzi mutu, pambuyo kuzimitsa ndi kutentha, kutentha firiji angagwiritsidwe ntchito kupanga zosiyanasiyana mbali zofunika za ntchito.

Chithandizo cha kutentha ndi njira yabwino kwambiri yosinthira ndikusintha mawonekedwe a chitsulo chozungulira cha 15CrMo alloy. Zimagwira ntchito yofunika kwambiri pakudalirika kwazinthu komanso chuma. The kutentha mankhwala a 15CrMo aloyi kuzungulira zitsulo zambiri zikuphatikizapo wamba kutentha mankhwala (annealing, normalizing, quenching, tempering) ndi pamwamba kutentha mankhwala (pamwamba quenching ndi mankhwala kutentha mankhwala-carburizing, nitriding, metalizing, etc.).

Mu uinjiniya wamakina, mbali zambiri zamakina, monga ma crankshaft, magiya, ma camshaft a injini zoyatsira mkati, ndi zida zochepetsera zofunika, sikuti zimangofunika kulimba kokwanira, pulasitiki ndi mphamvu yopindika pachimake, komanso zimafunikira makulidwe apamwamba mkati mwa makulidwe ena. . Kuuma, kukana kuvala kwakukulu komanso mphamvu zotopa kwambiri. Zomwe tazitchulazi njira zosiyanasiyana zochizira kutentha kwanthawi zonse zimakhala zovuta kukwaniritsa zofunikira zomwe zili pamwambazi panthawi imodzi, ndipo kugwiritsa ntchito kutentha kwapamwamba ndi njira yabwino kwambiri yokwaniritsira zofunikira izi panthawi imodzi.

Kuchiza kutentha pamwamba ndi njira yochizira kutentha yomwe imasintha mawonekedwe amtundu wa 15CrMo alloy round steel posintha mawonekedwe a pamwamba.
Kuzimitsa pamwamba ndi chithandizo cha kutentha chomwe chimasintha mawonekedwe a pamwamba chimodzi ndi chimodzi popanda kusintha mankhwala a pamwamba. Itha kuzindikirika ndi ma frequency apamwamba, ma frequency apakati kapena njira yotenthetsera yamagetsi yamagetsi kapena njira yotenthetsera moto. Chodziwika bwino ndi chakuti pamwamba pa zitsulo zozungulira za 15CrMo zozungulira zimatenthedwa mofulumira mpaka kutentha kozimitsa, ndipo pamene kutentha sikunasamutsire pakatikati pa gawolo, kumakhazikika mofulumira, kotero kuti kuuma kwapamwamba kumakhala kwakukulu, koma core akadali kulimba kwambiri.

Chithandizo chamankhwala ndi njira yochizira kutentha yomwe imasintha kapangidwe kake ndi kapangidwe ka chitsulo chozungulira cha 15CrMo alloy round. Mankhwala kutentha mankhwala akhoza kugawidwa mu njira monga carburizing, nitriding, carbonitriding, ndi metalizing malinga ndi zinthu zosiyanasiyana analowerera pamwamba pa 15CrMo aloyi kuzungulira zitsulo. Ndiwothandiza kwambiri pakuwongolera ndikuwongolera kukana kwa mavalidwe, kukana kwa dzimbiri komanso kukana kutopa kwa 15CrMo alloy round steel. Pakalipano, chithandizo cha kutentha kwa mankhwala chakula mofulumira, ndipo pali ntchito zambiri zamakono zatsopano.
