Cov Txheej Txheem Kho Kub ntawm 431 Stainless Steel Forged Block

Kev kho cua sov ntawm431 stainless hlau forged thaivfeem ntau muaj peb kauj ruam tseem ceeb:kev ua kom sov, hardening (kev kho kom tawv), thiabkev ua kom sovTxhua kauj ruam ua lub luag haujlwm tseem ceeb hauv kev ua tiav cov khoom siv kho tshuab thiab tiv taus xeb kawg.

1. Kev Ua Kub - Kev Txo Kev Nyuaj Siab thiab Kev Ua Kom Mos

Kev ua kom sovyog ua los txhim kho cov qauv ntawm cov noob thiab txo cov kev ntxhov siab sab hauv uas tsim thaum lub sijhawm forging. Cov kauj ruam no ua rau cov khoom siv yooj yim dua rau kev siv tshuab thiab ua kom muaj kev sib npaug ua ntej hardening.

Cov Txheej Txheem Annealing Ib Txwm Muaj:

  • Kub thiab txias:850–900°C

  • Lub Sijhawm Tuav:Txaus rau tag nrho lub thaiv kom ncav cuag qhov kub thiab txias

  • Txias:Txias qeeb hauv lub cub tawg kom tiv thaiv kev cuam tshuam

Cov txiaj ntsig ntawm kev ua kom sov:

  • Txo qhov nyuaj thiab brittleness

  • Txhim kho kev siv tshuab thiab ductility

  • Txo qhov kev ntxhov siab sab hauv kom ruaj khov dua

Tom qab annealing, cov khoom siv feem ntau yog mos thiab npaj txhij raukev ua kom raug or cov kauj ruam kho cua sov tom qab ntawd.

2. Kev Ua Kom Ruaj (Kev Tua Kom Tsis Txhob Kub) - Tsim Kom Muaj Zog Siab

Lubua kom tawvtheem yog theem tseem ceeb tshaj plaws rau431 stainless hlau forged thaiv, raws li nws hloov cov khoom siv los ntawm cov qauv ductile mus rau hauv ib qhotheem martensitic muaj zog heev.

Cov Txheej Txheem Kho Kom Ruaj Khoov:

  • Kub thiab txias:980–1035°C

  • Lub Sijhawm Tuav:Ntev txaus kom tso cai rau kev ua kom tiav austenitization (feem ntau 30-60 feeb, nyob ntawm qhov loj me)

  • Kev Tua Hluav Taws Xob:Roj los yog cua, nyob ntawm seb qhov tuab ntawm seem thiab qhov txias uas xav tau

Thaum lub sijhawm ua kom sov, cov qauv hloov pauv los ntawmferrite to austeniteThaum txias sai (quenched), lub austenite hloov mus uamartensite, ib qho qauv crystalline tawv heev thiab muaj zog.

Cov txiaj ntsig ntawm kev ua kom tawv:

  • Lub zog tensile:Txog li 1300 MPa

  • Qhov nyuaj:260–300 HB (tuaj yeem ncav cuag txog li 40 HRC nyob ntawm kev tempering)

  • Lub Zog Tawm:750–950 MPa

Cov Kev Xav Tseem Ceeb:

  • Kev tua cua txo qhov kev cuam tshuam rau cov blocks loj.

  • Kev ua kom roj quenching muaj qhov nyuaj dua rau cov ntu me me.

  • Kev tswj kom zoo ntawm qhov txias yog qhov tseem ceeb kom tsis txhob tawg lossis warping.

Tom qab ua kom tawv, cov khoom siv ua tiav qhov muaj zog tshaj plaws tab sis kuj tseem yuav ua rau tawg yooj yim - uas yog vim li caskev ua kom sovkauj ruam yog qhov tseem ceeb.

3. Kev Sib Npaug - Kev Sib Npaug Lub Zog thiab Kev Ruaj Ntseg

Kev ua kom sovua raws li kev ua kom tawv kom txo qhov brittleness thaum tseem khaws feem ntau ntawm lub zog tau txais. Nws cuam tshuam nrog kev rov ua kom sov cov khoom tawv kom qis dua, uas tso cai rau kev tswj hwm kev ntxhov siab thiab kev ua kom zoo dua qub.

Cov Txheej Txheem Tempering:

  • Kub thiab txias:620–760°C

  • Lub Sijhawm Tuav:1-2 teev nyob ntawm seb qhov loj ntawm lub block loj npaum li cas

  • Txias:Cua txias

Cov teebmeem ntawm kev kub ntxhov:

  • Txo kev ntxhov siab sab hauv thiab kev tawg yooj yim

  • Txhim khokev ua siab tawvthiabkev tiv thaiv kev cuam tshuam

  • Txhim khokev ruaj khov ntawm qhov ntevthaum lub sijhawm ua haujlwm

  • Tso cai rau kev hloov kho qhov nyuaj nyob ntawm daim ntawv thov

Piv txwv li:

  • Kub qis tempering (~ 620 ° C):Khaws cov hardness thiab lub zog siab dua.

  • Kub siab kub (~ 750 ° C):Muab kev tawv zoo dua thiab ductility.

Cov txheej txheem no ua kom ntseeg tau tias431 stainless hlau forged thaivua tiav ib qhokev sib xyaw ua ke ntawm qhov nyuaj, lub zog, thiab kev tawv nqaij, ua rau nws haum raucov chaw muaj kev ntxhov siab ntau.
