Annealing txheej txheem rau SMLS Pipes
Annealing muaj cua sov cov yeeb nkab steel seamless mus rau qhov ntsuas kub, tswj nws rau qee lub sijhawm, thiab tom qab ntawd maj mam txias. Cov txheej txheem no muaj ntau yam txiaj ntsig tseem ceeb:
Hardness Reduction: Txo qhov hardness ntawm cov yeeb nkab steel, txhim kho machinability.
Txhim kho Plasticity: Txhim kho cov yeeb nkab muaj peev xwm tiv thaiv sab nraud tsis muaj kev tawg.
Kev Nyuaj Siab: Tshem tawm cov kev ntxhov siab sab hauv los ntawm kev ua haujlwm txias lossis vuam, txo qhov kev pheej hmoo ntawm deformation thiab tawg.
Grain Refinement: Tsim kom muaj ib qho microstructure zoo sib xws, pab txhawb kev txhim kho toughness.
Cov nyhuv ntawm Annealing ntawm Toughness
Annealing ho txhim khu lub toughness ntawm seamless steel kav los ntawm refining lub grain qauv thiab txo cov kev ntxhov siab nyob rau hauv. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov ntaub ntawv uas muaj hardness siab, loj hauv kev ntxhov siab, lossis txias - cov khoom ua tiav. Los ntawm softening tus qauv thiab txhim kho ductility, annealing ua rau cov hlau ntau resistant rau brittle tsis ua hauj lwm.
Pom zoo daim ntawv thov
Annealing yog qhov zoo tagnrho rau cov qib steel uas yuav tsum tau muaj zog toughness tab sis tsis muaj zog nruj, xws li 20 # thiab 45 # steel kav.
Txheej txheem Annealing
Cua sov: tsa cov yeeb nkab steel rau qhov xav tau qhov kub thiab txias (nyob ntawm cov khoom siv thiab kev ua haujlwm tau zoo).
Soaking: Khaws qhov kub thiab txias rau lub sijhawm tshwj xeeb kom tso cai rau kev hloov pauv.
Ua kom txias: Maj mam txias cov yeeb nkab steel siv lub tshuab cua txias lossis cua txias kom ntseeg tau tias muaj qhov zoo ntawm microstructure.
Kev sib piv nrog lwm txoj kev kho cua sov
1. normalizing
Txheej Txheem: Ua kom sov siab tshaj qhov ntsuas kub tseem ceeb, tuav, thiab cua txias.
Cov txiaj ntsig ntawm Toughness: Txhim kho qhov sib xws thiab ua kom cov nplej ua kom zoo dua qub, txhim kho lub zog thiab tawv.
Qhov zoo tshaj plaws rau: Cov pa roj carbon nruab nrab (piv txwv li, 45 # steel, 40Cr steel) hauv cov ntawv thov kom muaj zog, lub zog, thiab hnav tsis kam.
2. Quenching thiab Tempering
quenching: ceev cua txias los ntawm kub kub kom nce hardness.
Tempering: Reheating mus rau qhov nruab nrab kub kom txo tau brittleness thiab txhim kho toughness.
Cov nyhuv ntawm Toughness: Kho lub zog thiab toughness sib npaug; haum rau siab -cov ntawv siv zog.
Qhov zoo tshaj plaws rau: Siab-lub zog alloy steels (xws li 40CrMo, 42CrMo) hauv tshuab thiab hydraulic systems.
3. Siab -Tsuas Kub Kub
Txheej txheem: Cua sov rau 550-650 degree, tuav, thiab txias.
Cov nyhuv ntawm Toughness: Txo brittleness, txhim khu kev qaug zog tiv thaiv thiab cuam tshuam toughness.
Qhov zoo tshaj plaws rau: Cov khoom siv hauv cov khoom siv siab (xws li, 30CrMnSi steel).
4. Kev Kho Kev laus
Txheej txheem: Tsawg-kub cua sov kom stabilize lub sab hauv ntawm cov hlau.
Cov nyhuv ntawm Toughness: Txhim kho hnav tsis kam thiab corrosion kuj, feem ntau siv rau siab - alloy steels.
Qhov zoo tshaj plaws rau: Aerospace thiab tob -sea engineering applications.
Xaus
Rau kev txhim kho seamless steel yeeb nkab toughness, kev xaiv ntawm kev kho cua sov nyob ntawm cov khoom muaj pes tsawg leeg thiab daim ntawv thov yuav tsum tau:
Annealing yog txheej txheem zoo tshaj plaws rau kev txhim kho toughness thaum txo hardness thiab sab hauv kev ntxhov siab.
Normalizing yog qhov zoo tagnrho rau cov ntawv thov uas xav tau ob qho tib si toughness thiab lub zog.
Quenching & Tempering yog siv thaum lub zog siab thiab nruab nrab toughness xav tau.
High -Tsub Tempering sib npaug ductility thiab cuam tshuam tsis kam.
Kev Kho Kev laus yog tshwj tseg rau siab -kev ua tau zoo alloy steels.
Zuag qhia tag nrho, annealing tseem yog txoj hauv kev zoo tshaj plaws rau kev ua kom lub zog ntawm cov kav dej seamless steel, ua kom muaj cov qauv ua kom zoo dua qub, txhim kho plasticity, thiab txo cov kev ntxhov siab sab hauv.
