Lub sab sauv ntawm lub puab tsaig txav ntawm lub puab tsaig crusher yog txuas nrog lub puab tsaig eccentric, qhov qis yog txhawb nqa los ntawm lub puab tsaig phaj, thiab lub puab tsaig ruaj ruaj yog tsau rau ntawm tus ncej. Thaum lub eccentric ncej tig, lub puab tsaig txav lub puab tsaig feem ntau bears lub extrusion txiav txim ntawm cov khoom, thaum lub puab tsaig ruaj ruaj feem ntau bears lub zawv zawg txiav txiav ntawm cov khoom. Raws li ib feem nrog siab coj tus nqi ntawm lub puab tsaig crusher, kev xaiv ntawm lub puab tsaig phaj cov ntaub ntawv muaj feem xyuam rau cov nqi thiab cov txiaj ntsig ntawm cov neeg siv.
High manganese hlau
High manganese steel yog cov khoom siv niaj hnub ntawm lub puab tsaig phaj ntawm lub puab tsaig crusher, uas muaj lub peev xwm zoo los tiv thaiv kev cuam tshuam. Txawm li cas los xij, vim yog cov qauv ntawm cov crusher, qhib lub kaum sab xis ntawm lub puab tsaig txav tau thiab ruaj khov yog qhov loj heev, uas yooj yim ua rau cov abrasive swb. Lub degree ntawm hardening tsis txaus, yog li lub hardness ntawm lub puab tsaig phaj yog tsawg, thiab cov khoom abrasive txiav nyob rau hauv luv luv, thiab lub puab tsaig phaj hnav sai dua.
Txhawm rau txhim kho lub neej kev pab cuam ntawm lub puab tsaig phaj, ntau yam khoom siv lub puab tsaig tau tsim, xws li ntxiv Cr, Mo, W, Ti, V, Nb thiab lwm yam khoom los hloov kho siab manganese hlau, thiab ua kom muaj kev sib cais. ntxiv dag zog rau kev kho mob ntawm siab manganese hlau. Txhim kho nws qhov pib hardness thiab yield zog. Tsis tas li ntawd, nruab nrab-manganese steel, low-alloy steel, high-chromium cam khwb cia hlau thiab high-manganese steel composites kuj tau tsim, tag nrho cov uas tau zoo siv nyob rau hauv ntau lawm.
Medium manganese hlau
Nruab nrab manganese hlau tau tsim los ntawm Climax Molybdenum Co., Ltd. thiab tau suav nrog US patent xyoo 1963. Lub tshuab hardening yog: thaum tus nqi ntawm manganese txo qis, kev ruaj ntseg ntawm austenite txo, thiab thaum nws cuam tshuam los yog hnav, Lub austenite yog nquag deformation thiab induces martensitic transformation, yog li txhim kho nws hnav tsis kam. Cov muaj pes tsawg leeg (%) ntawm nruab nrab manganese hlau: 0.7-1.2C, 6-9Mn, 0.5-0.8Si, 1-2Cr thiab lwm yam kab kawm V, Ti, Nb, tsis tshua muaj ntiaj teb, thiab lwm yam. Lub puab tsaig phaj tuaj yeem nce ntau dua 20% piv nrog cov hlau manganese siab, thiab tus nqi sib npaug rau cov hlau manganese siab.
High chromium cam khwb cia hlau
Txawm hais tias siab chromium cam khwb cia hlau muaj siab hnav tsis kam, tab sis vim nws cov tawv tsis zoo, siv cov chromium cam khwb cia hlau ua lub puab tsaig phaj yuav tsis tas ua tiav cov txiaj ntsig zoo. Nyob rau hauv xyoo tas los no, high chromium cam khwb cia hlau tau siv los inlay los yog khi siab manganese steel puab tsaig los tsim cov puab tsaig. Cov txheeb ze hnav tsis kam yog siab li 3 zaug, thiab kev pabcuam lub neej ntawm lub puab tsaig tau txhim kho zoo. Qhov no kuj yog ib txoj hauv kev zoo los ua kom lub neej ua haujlwm ntawm lub puab tsaig phaj, tab sis nws cov txheej txheem tsim khoom yog qhov nyuaj, yog li nws nyuaj rau kev tsim khoom.
Nruab nrab carbon tsawg alloy cam khwb cia hlau
Nruab nrab-carbon low-alloy cam khwb cia hlau kuj yog siv dav siv cov khoom siv-resistant. Vim nws cov hardness siab (≥45HRC) thiab tsim nyog toughness (≥15J / cm²), nws muaj peev xwm tiv taus cov khoom txiav thiab rov extrusion. Fatigue spalling, yog li nthuav tawm zoo hnav tsis kam. Nyob rau tib lub sijhawm, qhov nruab nrab-carbon low-alloy cam khwb cia hlau kuj tseem tuaj yeem kho qhov sib xyaw thiab cov txheej txheem kho cua sov kom hloov cov hardness thiab toughness nyob rau hauv ntau yam kom tau raws li qhov yuav tsum tau ntawm cov kev ua haujlwm sib txawv. Kev tsim khoom thiab kev sim ua haujlwm qhia tau hais tias lub neej kev pab cuam ntawm qhov nruab nrab-carbon low-alloy steel lub puab tsaig phaj tuaj yeem ua tau ntau dua 3 zaug ntev dua li cov hlau manganese siab.
Cov lus qhia rau kev xaiv cov khoom siv lub puab tsaig
Yuav kom suav tau, qhov zoo tshaj plaws, kev xaiv cov khoom siv lub puab tsaig yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm cov tawv tawv thiab siab tawv, tab sis cov tawv tawv thiab tawv tawv ntawm cov khoom feem ntau tsis sib haum. Yog li ntawd, hauv kev xaiv cov khoom siv tiag tiag, nws yog qhov yuav tsum tau nkag siab txog kev ua haujlwm thiab xaiv qhov tsim nyog. khoom.
Impact load yog ib qho tseem ceeb uas yuav tsum tau xav txog hauv kev xaiv cov khoom tsim nyog.
Qhov loj dua qhov tshwj xeeb, qhov hnyav dua qhov hnav, qhov ntau lumpy cov khoom crushed, thiab ntau dua qhov cuam tshuam nws dais. Nyob rau lub sijhawm no, hloov kho lossis dispersion ntxiv dag zog rau siab manganese hlau tseem tuaj yeem siv los ua cov khoom ntawm cov khoom xaiv.
Rau nruab nrab thiab me crushers, qhov cuam tshuam load ntawm qhov hnav tsis tau loj heev, thiab nws yog ib qho nyuaj rau kev ua hauj lwm nyuaj nrog siab manganese hlau. Raws li cov kev ua haujlwm zoo li no, cov txiaj ntsig zoo thiab kev lag luam tuaj yeem tau txais los ntawm kev xaiv nruab nrab-carbon low-alloy steel lossis high-chromium cam khwb cia hlau / low-alloy steel composite khoom.
Qhov muaj pes tsawg leeg thiab hardness ntawm cov ntaub ntawv kuj yog ib qho tseem ceeb uas yuav tsis raug ignored nyob rau hauv cov khoom tsim nyog xaiv.
Feem ntau hais lus, qhov siab dua qhov hardness ntawm cov khoom, qhov siab dua qhov yuav tsum tau muaj hardness rau cov khoom ntawm cov khoom hnav. Yog li ntawd, nyob rau hauv cov xwm txheej ntawm ua tau raws li qhov yuav tsum tau toughness, cov ntaub ntawv uas siab hardness yuav tsum tau xaiv ntau npaum li cas.
Kev xaiv cov khoom tsim nyog yuav tsum tau xav txog kev hnav lub cev ntawm cov khoom hnav.
Yog tias txiav hnav yog cov khoom tseem ceeb, hardness yuav tsum tau txiav txim siab ua ntej thaum xaiv cov khoom; Yog hais tias cov yas hnav los yog qaug zog hnav yog cov khoom tseem ceeb, plasticity thiab toughness yuav tsum tau txiav txim siab ua ntej thaum xaiv cov khoom.
Ntawm chav kawm, thaum xaiv cov ntaub ntawv, qhov kev xav ntawm cov txheej txheem yuav tsum tau txiav txim siab, kom nws yooj yim rau kev npaj ntau lawm thiab kev tswj kom zoo.
Shanvim raws li lub ntiaj teb no tus neeg muag khoom ntawm crusher hnav qhov chaw, peb tsim lub khob hliav qab crusher coj qhov chaw rau ntau hom ntawm crushers. Peb muaj ntau tshaj 20 xyoo ntawm keeb kwm nyob rau hauv lub teb ntawm CRUSHER WEAR PARTS. Txij li xyoo 2010, peb tau xa tawm mus rau Asmeskas, Europe, Africa thiab lwm lub tebchaws hauv ntiaj teb.
