2. Lub Hauv Paus Metallurgical: Kev Tshawb Fawb Txog Khoom Siv Rau Kev Siv Mining

2.1 Cov Qauv Xaiv Cov Hlau Alloy rau Kev Ua Haujlwm Hnyav

Qhov chaw ua haujlwm ntawm lub tshuab khawb av sab saud yog qhov xav tau cov khoom siv ntau tshaj plaws hauv kev lag luam khoom siv hnyav. Lub Cheebtsam yuav tsum ua tib lub sijhawm:

• Tiv thaiv kev hnav abrasive los ntawm kev sib cuag tas mus li nrog cov saw hlau abrasive thiab kev raug rau cov hmoov av mining uas muaj quartz, silicates, thiab lwm yam minerals abrasive heev
• Tiv taus cov khoom hnyav los ntawm kev tsav tsheb hla thaj chaw khawb av thiab kev co thaum lub sijhawm khawb av
• Tswj kev ruaj khov ntawm cov qauv hauv qab kev thauj khoom cyclic tshaj 10⁷ cycles thoob plaws lub neej ntawm lub tshuab
• Khaws cia qhov ruaj khov txawm tias raug rau qhov kub thiab txias heev (-40 ° C txog + 50 ° C), dej noo, thiab cov tshuaj lom neeg suav nrog roj, roj nplua nyeem, thiab cov tshuaj reagents hauv kev khawb av

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 cov ntawv thov mining:

42CrMo Chromium-Molybdenum Alloy: Qhov no yog cov khoom siv zoo tshaj plaws rau cov menyuam sab saud hauv chav kawm mining. Nrog cov ntsiab lus carbon ntawm 0.38-0.45%, chromium ntawm 0.90-1.20%, thiab molybdenum ntawm 0.15-0.25%, 42CrMo (zoo ib yam li AISI 4140) muab:

• Kev ua kom tawv zoo heev rau kev ua kom tawv ntawm cov khoom loj
• Kev tiv thaiv kev qaug zog zoo tshaj plaws rau cov ntawv thov cyclic loading
• Kev tawv zoo ntawm cov qib siab hardness
• Kev tiv thaiv rau kev kub ntxhov thaum lub sijhawm kho cua sov

40Cr Chromium Alloy: Rau cov ntawv thov uas xav tau qhov sib npaug ntawm cov khoom sib txawv me ntsis, 40Cr (zoo ib yam li AISI 5140) nrog cov pa roj carbon 0.37-0.44% thiab chromium 0.80-1.10% muab qhov nyuaj zoo heev nrog kev vuam zoo rau cov qauv tsim.

50Mn Manganese Hlau: Rau cov menyuam lub cev qhov twg kev tiv thaiv kev hnav zoo dua li kev ua kom tawv, 50Mn nrog carbon 0.45-0.55% thiab manganese 1.4-1.8% muab qhov tawv tawv zoo heev thiab kev tiv thaiv kev hnav.

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 Xeem Mill (MTRs) uas lees paub cov tshuaj lom neeg sib xyaw nrog kev tshuaj xyuas tshwj xeeb ntawm cov ntsiab lus (C, Si, Mn, P, S, Cr, Mo, Ni yog tias siv tau). 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 txog cov khoom siv kho tshuab thiab lub neej ua haujlwm ntawm cov menyuam sab saud. Txawm hais tias kev casting muaj cov txiaj ntsig zoo rau cov qauv yooj yim, nws tsim cov qauv noob sib npaug nrog kev taw qhia tsis sib xws, qhov muaj peev xwm porosity, thiab kev tiv thaiv kev cuam tshuam qis dua. Cov chaw tsim khoom siv qib siab hauv chav kawm mining tsuas yog siv cov khoom siv kub kaw-tuag rau lub cev menyuam.

Cov txheej txheem forging rau SY950 / SY980 chav kawm Cheebtsam pib nrog kev txiav cov hlau loj-txoj kab uas hla mus rau qhov hnyav meej, cua sov lawv mus rau kwv yees li 1150-1250 ° C kom txog thaum tag nrho austenitized, tom qab ntawd raug rau lawv qhov kev hloov pauv siab ntawm cov tuag precision-machined hauv hydraulic presses 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 kev siv mining qhov twg cov khoom 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 sab saud ntawm lub tshuab khawb av pom tseeb hauv nws qhov kev ua haujlwm nyuaj - qhov chaw tawv, tiv taus hnav ua ke nrog lub hauv paus ruaj khov, nqus tau kev cuam tshuam:

Kev Tua Kab thiab Kev Kub Siab (Q&T): Tag nrho lub cev forged roller yog austenitized ntawm 840-880 ° C, tom qab ntawd tua sai sai hauv dej, roj, lossis cov tshuaj polymer. Qhov kev hloov pauv no tsim cov martensite - muab qhov nyuaj tshaj plaws tab sis nrog rau kev tawg yooj yim. Kev kub siab tam sim ntawd ntawm 500-650 ° C tso cai rau cov pa roj carbon kom ua rau cov carbides zoo, txo cov kev ntxhov siab sab hauv thiab rov qab ua kom muaj zog. Qhov nyuaj ntawm cov tub ntxhais feem ntau yog txij li 280-350 HB (29-38 HRC), muab qhov nyuaj zoo tshaj plaws rau kev nqus cov kev cuam tshuam hauv kev siv mining.

Kev Kho Kom Qhov Chaw Induction Hardening: Tom qab ua tiav qhov kev ua tiav, qhov chaw hnav tseem ceeb - qhov txoj kab uas hla ntawm lub tread - yuav raug kho kom qhov chaw induction hardening. Lub kauj inductor tooj liab uas tsim los ntawm kev ua haujlwm raug nyob ib puag ncig lub Cheebtsam, ua rau muaj cov hluav taws xob eddy uas ua rau cov txheej saum npoo kub sai sai mus rau qhov kub austenitizing (900-950 ° C) hauv ob peb feeb. Kev tua dej tam sim ntawd tsim cov ntaub ntawv martensitic ntawm 8-12 hli tob nrog qhov nyuaj ntawm HRC 55-60, muab kev tiv thaiv zoo rau kev hnav abrasive los ntawm kev sib cuag ntawm cov saw hlau.

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 55-60) 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.

Qhov kev sib txawv ntawm qhov tawv tawv no tsim cov qauv sib xyaw zoo tshaj plaws rau kev siv hauv kev khawb av: ib qho chaw uas tsis yooj yim hnav uas tiv taus ntau lab lub voj voog ntawm kev sib txhuam nrog cov saw hlau, txhawb nqa los ntawm lub hauv paus ruaj khov uas nqus cov khoom cuam tshuam yam tsis muaj kev tawg loj heev.

A: Cov yam ntxwv txo lub neej ntawm cov menyuam suav nrog: cov ntsiab lus quartz / silica siab hauv cov hlau (kev hnav sai), dej / av nkos raug (kev ntxhov siab ntawm lub foob), qhov kub thiab txias heev (kev puas tsuaj ntawm cov roj nplua nyeem), kev thauj khoom cuam tshuam (kev qaug zog ntawm cov kabmob), thiab kev mus ncig ceev ceev tas mus li (kev tsim cua sov).

Q: Cov kev coj ua txij nkawm twg txuas ntxiv lub neej ntawm cov menyuam sab saud hauv kev ua haujlwm khawb av?
A: Cov kev coj ua tseem ceeb suav nrog kev saib xyuas qhov nruj ntawm txoj kev, kev tshuaj xyuas tsis tu ncua rau qhov xwm txheej ntawm lub foob, zam kev ntxuav siab ntawm cov foob, hloov pauv sai sai thaum muaj kev hnav ntau dhau, thiab cov tswv yim hloov pauv raws li lub kaw lus.

Q: Kuv yuav xaiv li cas ntawm cov kev teeb tsa sib txawv rau cov menyuam sab saud rau cov ntawv thov khawb av?
A: Kev xaiv nyob ntawm: cov lus qhia txog txoj kev sib txuas (qhov siab, qhov profile ntawm txoj kev tsheb ciav hlau), kev siv tshuab (hom kev khawb av, av), cov xwm txheej ua haujlwm (qib kev ua qias tuaj, huab cua), thiab cov kev cai ua haujlwm (lub hom phiaj ntawm lub neej ua haujlwm, kev txwv tus nqi). Kev txhawb nqa engineering los ntawm cov chaw tsim khoom zoo li CQC TRACK tuaj yeem coj kev xaiv zoo tshaj plaws.

Daim ntawv tshaj tawm txog kev siv tshuab no yog rau cov thawj coj saib xyuas cov khoom siv, cov kws tshaj lij kev yuav khoom, thiab cov neeg ua haujlwm saib xyuas hauv kev ua haujlwm khawb av. Cov lus qhia thiab cov lus pom zoo yog raws li cov qauv kev lag luam thiab cov ntaub ntawv chaw tsim khoom muaj thaum lub sijhawm tshaj tawm. Txhua lub npe chaw tsim khoom, cov lej ntawm qhov chaw, thiab cov qauv qauv tsuas yog siv rau kev txheeb xyuas xwb. Ib txwm sab laj nrog cov ntaub ntawv khoom siv thiab cov kws tshaj lij kev tsim nyog rau kev txiav txim siab tshwj xeeb rau daim ntawv thov.
