2. Lub Hauv Paus Metallurgical: Kev Tshawb Fawb Txog Khoom Siv Rau Cov Kev Siv Hnyav Excavator

2.1 Cov Qauv Xaiv Cov Hlau Alloy

Qhov chaw ua haujlwm ntawm 30-35 tuj chav kawm excavator pem hauv ntej idler muaj cov khoom siv xav tau heev. Cov khoom yuav tsum tib lub sijhawm:

• Tiv thaiv kev hnav khaub ncaws tsis zoo los ntawm kev sib cuag tas li nrog txoj hlua thiab kev raug rau av, xuab zeb, pob zeb, thiab cov khib nyiab hauv kev khawb av uas muaj cov zaub mov tsis zoo heev.
• Tiv taus cov khoom hnyav los ntawm kev khawb av, kev mus los ntawm tshuab hla thaj chaw ntxhib, thiab kev thauj khoom dynamic thaum lub sijhawm ua haujlwm
• Tswj kev ruaj khov ntawm cov qauv hauv qab kev thauj khoom cyclic uas tuaj yeem tshaj 10⁷ cycles thoob plaws lub neej ntawm lub tshuab
• Khaws cia qhov ruaj khov txawm tias raug rau qhov kub thiab txias heev, dej noo, thiab cov tshuaj lom neeg

Cov chaw tsim khoom zoo xws li CQC TRACK xaiv cov qib hlau sib xyaw tshwj xeeb uas ua tiav qhov sib npaug zoo tshaj plaws ntawm qhov nyuaj, kev tawv, thiab kev tiv taus qaug zog rau chav kawm ntawv no:

50Mn Manganese Steel: Qhov no yog cov khoom siv tseem ceeb rau cov excavator idlers. Nrog cov ntsiab lus carbon ntawm 0.45-0.55% thiab manganese ntawm 1.4-1.8%, 50Mn muab:

• Kev ua kom tawv zoo heev rau kev ua kom tawv ntawm cov khoom loj
• Kev tiv thaiv zoo los ntawm kev tsim carbide thaum lub sijhawm kho cua sov
• Muaj zog txaus rau kev nqus tau thaum kho cua sov kom zoo
• Kev siv nyiaj tsim khoom ntau

40Cr Chromium Alloy: Rau cov ntawv thov uas xav tau kev ua kom tawv thiab qaug zog, 40Cr (zoo ib yam li AISI 5140) nrog cov pa roj carbon 0.37-0.44% thiab chromium 0.80-1.10% muab:

• Txhim kho qhov tawv kom zoo rau cov khoom sib xws hauv cov ntu loj
• Lub zog qaug zog ntxiv los ntawm chromium carbides
• Zoo toughness ntawm qib hardness nruab nrab
• Cov lus teb zoo heev rau kev ua kom tawv tawv induction

SAE 4140 / 42CrMo Premium Alloy: Rau cov ntawv thov uas xav tau tshaj plaws, cov chaw tsim khoom siv SAE 4140 (zoo ib yam li 42CrMo) nrog lub zog tensile kawg ntawm 950 MPa, muab kev ruaj khov tshwj xeeb rau cov voj voog hnyav.

Kev Tshawb Nrhiav Cov Khoom Siv: Cov chaw tsim khoom muaj koob npe muab cov ntaub ntawv pov thawj txog cov khoom siv, suav nrog Cov Ntawv Qhia Txog Kev Ntsuas Mill (MTRs) uas lees paub cov tshuaj lom neeg sib xyaw nrog kev tshuaj xyuas tshwj xeeb rau cov ntsiab lus. Kev tshuaj xyuas spectrographic lees paub cov tshuaj lom neeg ntawm cov hlau sib xyaw nrog cov lus qhia tau ntawv pov thawj.

2.2 Forging vs. Casting: Qhov tseem ceeb ntawm cov qauv nplej

Txoj kev tsim thawj zaug txiav txim siab qhov khoom siv kho tshuab thiab lub neej ua haujlwm ntawm tus neeg ua haujlwm. Thaum casting muab cov txiaj ntsig zoo rau cov qauv yooj yim, nws tsim cov qauv noob sib npaug nrog kev taw qhia tsis raug, qhov muaj peev xwm porosity, thiab kev cuam tshuam qis dua. Cov chaw tsim khoom siv excavator idler tshwj xeeb tsuas yog siv cov khoom siv kub kaw-tuag rau lub log idler thiab cov khoom yoke.

Cov txheej txheem forging pib nrog kev txiav cov hlau loj uas muaj txoj kab uas hla mus rau qhov hnyav meej, ua kom sov rau kwv yees li 1150-1250 ° C kom txog thaum austenitized tag nrho, tom qab ntawd raug rau qhov kev hloov pauv siab ntawm cov pwm precision-machined hauv cov xovxwm hydraulic uas muaj peev xwm ntawm ntau txhiab tons ntawm lub zog.

Kev kho cua sov no ua rau cov noob nplej ntws tas mus li uas ua raws li cov duab ntawm cov khoom, sib dhos cov ciam teb ntawm cov noob nplej perpendicular rau cov lus qhia tseem ceeb ntawm kev ntxhov siab. Cov qauv tsim tau qhia txog 20-30% siab dua qhov muaj zog qaug zog thiab nqus tau lub zog cuam tshuam ntau dua piv rau lwm cov kev xaiv cam khwb cia - qhov zoo tseem ceeb hauv cov ntawv thov uas qhov kev cuam tshuam tuaj yeem hnyav.

Tom qab forging, cov khoom yuav raug tswj kom txias kom tiv thaiv kev tsim cov microstructures tsis zoo xws li Widmanstätten ferrite lossis cov carbide nag lossis daus ntau dhau.

2.3 Kev Tsim Kho Kub Ob Chav Khoom

Qhov kev txawj ntse ntawm cov hlau nplaum ntawm lub tshuab ua haujlwm hnyav zoo qhia tau meej hauv nws qhov profile hardness uas tau tsim tshwj xeeb - qhov chaw tawv, hnav-resistant ua ke nrog lub hauv paus tawv, cuam tshuam-absorbing:

Kev Tua Kab thiab Kev Kub Siab (Q&T): Tag nrho lub cev forged idler yog austenitized ntawm 840-880 ° C, tom qab ntawd sai sai quenched hauv dej agitated, roj, lossis polymer kua. Qhov kev hloov pauv no tsim martensite - muab qhov nyuaj tshaj plaws tab sis nrog kev sib txhuam brittleness. Tam sim ntawd tempering ntawm 500-650 ° C tso cai rau carbon kom precipitate ua cov carbides zoo, txo cov kev ntxhov siab sab hauv thiab rov qab kho qhov tawv. Qhov tawv ntawm lub hauv paus feem ntau yog txij li 280-350 HB (29-38 HRC), muab qhov tawv zoo tshaj plaws rau kev nqus kev cuam tshuam hauv cov ntawv thov hnyav.

Kev Kho Kom Qhov Chaw Induction Hardening: Tom qab ua tiav kev ua tiav, cov nplaim hnav tseem ceeb - tshwj xeeb tshaj yog lub tread diameter thiab flange faces - dhau los ntawm kev kho kom qhov chaw induction hardening. Lub kauj inductor tooj liab uas tsim los ntawm kev ua haujlwm raug nyob ib puag ncig cov khoom, ua rau cov hluav taws xob eddy uas ua rau cov txheej saum npoo kub sai sai rau qhov kub austenitizing hauv ob peb feeb. Kev quenching tam sim ntawd tsim cov ntaub ntawv martensitic ntawm 8-12 hli tob nrog qhov nyuaj ntawm HRC 58-62, muab kev tiv thaiv zoo rau kev hnav abrasive los ntawm kev sib cuag ntawm txoj hlua.

Kev Txheeb Xyuas Qhov Hardness Profile: Cov chaw tsim khoom zoo ua qhov microhardness traverses ntawm cov khoom qauv los xyuas kom meej qhov tob ntawm lub thawv ua raws li cov lus qhia. Qhov hardness gradient ntawm qhov chaw (HRC 58-62) los ntawm lub thawv hardened mus rau lub hauv paus (280-350 HB) yuav tsum ua raws li kev hloov pauv tswj kom tiv thaiv kev tawg lossis kev sib cais ntawm lub thawv thiab lub hauv paus thaum muaj kev cuam tshuam.

2.4 Cov Txheej Txheem Kev Ntsuam Xyuas Zoo

Cov chaw tsim khoom zoo li CQC TRACK siv ntau theem kev txheeb xyuas zoo thoob plaws hauv kev tsim khoom, nrog rau cov txheej txheem txhim kho rau cov khoom siv hnyav:

• Kev Tshuaj Xyuas Cov Khoom Siv Spectroscopic: Paub meej tias cov tshuaj lom neeg ntawm cov hlau sib xyaw ua ke raws li cov lus qhia tau ntawv pov thawj thaum tau txais cov khoom siv raw, nrog rau kev txheeb xyuas cov ntsiab lus zoo dua rau cov hlau sib xyaw tseem ceeb.
• Kev Ntsuas Ultrasonic (UT): Kev tshuaj xyuas 100% ntawm cov khoom tseem ceeb lees paub qhov ruaj khov sab hauv, nrhiav pom txhua qhov porosity hauv nruab nrab, cov khoom suav nrog, lossis laminations uas tuaj yeem ua rau muaj kev puas tsuaj rau cov qauv hauv qab cov khoom hnyav.
• Kev Txheeb Xyuas Qhov Nyuaj: Kev kuaj xyuas qhov nyuaj ntawm Rockwell lossis Brinell lees paub ob qho tib si qhov nyuaj ntawm lub hauv paus tom qab kev kho Q&T thiab qhov nyuaj ntawm qhov chaw tom qab kev kho kom tawv. Cov nqi kuaj xyuas zoo dua rau cov khoom siv hnyav.
• Kev Tshuaj Xyuas Cov Khoom Sib Nqus (MPI): Tshuaj xyuas cov chaw tseem ceeb—tshwj xeeb yog cov hauv paus flange thiab kev hloov pauv ntawm tus ncej—nrhiav pom cov kab nrib pleb lossis cov kub hnyiab uas ua rau muaj kev rhiab heev.
• Kev Txheeb Xyuas Qhov Loj: Cov Tshuab Ntsuas Sib Koom Tes (CMM) txheeb xyuas qhov loj me tseem ceeb, nrog rau kev tswj hwm cov txheej txheem suav txheeb xyuas cov ntsuas peev xwm ua haujlwm (Cpk) tshaj 1.33 rau cov yam ntxwv tseem ceeb.
• Kev Ntsuas Tshuab: Cov khoom ua piv txwv raug kuaj qhov tensile thiab kev ntsuas kev cuam tshuam (Charpy V-notch) ntawm qhov kub qis dua kom paub tseeb tias muaj zog rau kev ua haujlwm hauv huab cua txias.
