Intsimbi ephantsi kwe-alloyi ekwazi ukumelana nobushushu, yomelele kunentsimbi ye-12CrMo, ukuqina okungaphantsi kancinane, kwi-500-550 ° C okanye ngaphantsi inokumelana nobushushu obuphezulu kunye nokumelana ne-oxidation, kunye neempawu ezilungileyo zoomatshini, ubugcisa kunye noxinzelelo olubandayo lweplastiki elungileyo. weldability fair. Isetyenziselwa ikakhulu ukuveliswa kombhobho wentsimbi enomthungo ohlukeneyo kunye neshiti.



15CrMo Izicelo:



 Umbhobho womphunga ongundoqo weparameters zomphunga we-510 ° C, 530 ° C iiparamitha zomphunga we. kwibhoyila superheater iityhubhu, catheters kunye noxinzelelo oluphezulu umphunga header, emva quenching kunye nokuqukumbela, kwiqondo lobushushu kwigumbi ingasetyenziselwa ukuvelisa ezahlukeneyo iindawo ezibalulekileyo zomsebenzi.

Unyango lobushushu linyathelo elisebenzayo kakhulu lokuphucula kunye nokuguqula iipropathi ze-15CrMo ialloy round steel. Idlala indima ebaluleke kakhulu ekuthembekeni kwemveliso kunye noqoqosho. Unyango ubushushu 15CrMo ingxubevange intsimbi ngeenxa ngokuqhelekileyo ibandakanya unyango ubushushu eqhelekileyo (annealing, normalizing, quenching, tempering) kunye nonyango ubushushu phezu komhlaba (umphezulu quenching kunye unyango ubushushu imichiza-carburizing, nitriding, metalizing, njl.).

Kubunjineli boomatshini, iindawo ezininzi zoomatshini, ezinjengee-crankshafts, iigiya, ii-camshafts zeenjini zokutsha zangaphakathi, kunye neegiya kwizinciphisi ezibalulekileyo, azifuni nje ubunzima obaneleyo, iplastiki kunye namandla okugoba kumbindi, kodwa zikwafuna ukutyeba okuphezulu komphezulu ngaphakathi kobunzima obuthile. . Ukuqina, ukumelana nokunxiba okuphezulu kunye namandla aphezulu okudinwa. Iindlela ezahlukeneyo zokunyanga ubushushu zikhankanywe ngasentla kunzima ukuhlangabezana neemfuno zokusebenza ezingentla ngaxeshanye, kwaye ukusetyenziswa konyango lobushushu bomhlaba yeyona ndlela isebenzayo yokufezekisa ezi mfuno zokusebenza ngexesha elinye.

Unyango lobushushu bomhlaba yindlela yonyango yobushushu etshintsha iipropathi zomphezulu we-15CrMo ingxubevange yentsimbi ejikelezayo ngokuguqula ubume bomaleko womphezulu.
Ukucima umphezulu lunyango lobushushu olutshintsha ubume bomphezulu omnye komnye ngaphandle kokutshintsha ukwakheka kweekhemikhali kumphezulu. Inokuqondwa ngamaza omoya aphezulu, amaza aphakathi okanye amandla akhoyo ngoku indlela yokufudumeza okanye indlela yokufudumeza idangatye. Into eqhelekileyo kukuba umphezulu we-alloy ye-15CrMo ejikelezileyo yentsimbi ifudunyezwa ngokukhawuleza kwiqondo lokushisa lokucima, kwaye xa ubushushu bungadluliswanga kumbindi wenxalenye, bupholile ngokukhawuleza, ukwenzela ukuba ubunzima bomhlaba buphezulu, kodwa undoqo usenokuqina okuphezulu.

Unyango lweMichiza yindlela yonyango yobushushu etshintsha ukubunjwa kweekhemikhali kunye nesakhiwo somgangatho ophezulu we-15CrMo alloy round steel. Unyango lobushushu bekhemikhali lunokwahlulwa ngokweendlela ezinje nge-carburizing, i-nitriding, i-carbonitriding, kunye ne-metalizing ngokwezinto ezahlukeneyo ezingenwe kumphezulu we-15CrMo intsimbi engqukuva. Isebenza kakhulu ekuphuculeni nasekuphuculeni ukumelana nokunxiba, ukuxhathisa ukubola kunye nokumelana nokudinwa kwe-15CrMo i-alloy round steel. Okwangoku, unyango lobushushu beekhemikhali luphuhliswe ngokukhawuleza, kwaye kukho izicelo ezininzi zobuchwepheshe obutsha.
