35CrMoVA Cov Qauv Hlau Bar
35CrMoV yog siv tom qab quenching thiab tempering. Hauv kev lag luam hnyav lossis nruab nrab - loj machinery manufacturing kev lag luam, nws yog siv los tsim cov khoom tseem ceeb uas ua haujlwm nyob rau hauv kev ntxhov siab, xws li chav turbine impellers, advanced turbine blowers thiab compressor rotors uas ua hauj lwm ntawm 500 mus rau 520℃ntev. Npog discs, ncej discs, tsis muaj zog generator shafts thiab qhov chaw ntawm lub cav muaj zog, thiab lwm yam.

35CrMoVA puag ncig pas nrig yam ntxwv thiab daim ntawv thov Scope
Lub hardenability thiab kub siab zog yog zoo dua 34CrMo steel. Dej- roj quenching tshav kub kho tuaj yeem txhim kho tus nqi cuam tshuam. Lub zog creep thiab durability ntawm 550℃ob leeg tshaj 34CrMo, tab sis tom qab 5000h laus, cov khoom siv kho tshuab poob qis heev. Nws yog siv rau rotors, impellers, lub tshuab hluav taws xob nplhaib forgings thiab lwm yam tseem ceeb thiab lub zog ua haujlwm nyob rau hauv kev ntxhov siab nrog kev ua haujlwm kub hauv qab 500 txog 520 degree.

Kev xa khoom: Kev xa tawm hauv kev kho cua sov (normalizing, annealing lossis kub tempering) lossis tsis yog -kev kho cua sov, cov xwm txheej xa khoom yuav tsum tau teev tseg hauv daim ntawv cog lus.
Cov yam ntxwv tseem ceeb: Cov hlau no muaj lub zog siab thiab zoo hardenability. Qhov tseem ceeb hardenable txoj kab uas hla hauv cov roj yog 25 ~ 108mm. Nws muaj me ntsis temper brittleness thaum kho cua sov, tab sis cov hlau tsis tshua muaj plasticity thiab tsis zoo weldability thaum txias deformation.
