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 ntawm qhov siab ntawm lub puab tsaig tawg thiab hnav, kev xaiv cov khoom siv lub puab tsaig muaj feem xyuam nrog cov nqi thiab cov txiaj ntsig ntawm cov neeg siv.
Siab manganesesteel High manganese steel yog cov khoom siv niaj hnub ntawm lub puab tsaig crusher lub puab tsaig phaj, muaj kev cuam tshuam zoo rau kev thauj khoom, tab sis vim yog vim li cas ntawm cov qauv crusher, lub kaum sab xis ntawm lub puab tsaig thiab lub puab tsaig ruaj ruaj yog loj heev, yooj yim ua rau abrasive zawv zawg, vim rau deformation hardening tsis txaus ua rau lub puab tsaig phaj nto hardness yog tsawg, abrasive luv-ntau txiav, puab tsaig phaj hnav sai dua. Txhawm rau txhim kho lub neej kev pab cuam ntawm lub puab tsaig phaj, ntau yam khoom siv ntawm lub puab tsaig phaj tau tsim, xws li ntxiv Cr, Mo, W, Ti, V, Nb thiab lwm yam khoom los hloov kho cov hlau manganese siab, thiab ua kom muaj zog ntxiv. kev kho mob ntawm cov hlau manganese siab los txhim kho nws qhov pib hardness thiab yield zog. Tsis tas li ntawd, qhov sib xyaw ntawm nruab nrab manganese steel, qis alloy steel, siab chromium cam khwb cia hlau thiab siab manganese steel tau tsim, thiab cov txiaj ntsig zoo tau ua tiav hauv kev tsim khoom.
Tuam Tshoj Manganese Steel yog thawj zaug tsim los ntawm Tuam Txhab Climax Molybdenum thiab tau raug teev npe nyob rau hauv Tebchaws Meskas patent xyoo 1963. Cov txheej txheem hardening yog raws li nram no: tom qab txo cov manganese cov ntsiab lus, kev ruaj ntseg ntawm austenite txo, thiab thaum muaj kev cuam tshuam los yog hnav, austenite yog nquag deformation-vim txoj kev hloov pauv ntawm martensitic, uas txhim kho nws cov hnav tsis kam. Ib txwm muaj pes tsawg leeg ntawm 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 neej ua haujlwm tiag tiag ntawm nruab nrab manganese steel lub puab tsaig phaj yog ntau dua 20% siab dua li cov hlau manganese siab, thiab tus nqi yog piv rau cov hlau manganese siab.
03 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, kev siv cov chromium cam khwb cia hlau siab ua lub puab tsaig phaj tsis tas yuav ua tiav cov txiaj ntsig zoo. Nyob rau hauv xyoo tas los no, siab chromium cam khwb cia hlau los yog bonded rau siab manganese steel puab tsaig phaj los tsim ib tug ob lub puab tsaig phaj, tus txheeb ze hnav tsis kam mus txog 3 zaug, thiaj li hais tias lub neej kev pab cuam ntawm lub puab tsaig phaj ho nce. Qhov no kuj yog ib txoj hauv kev zoo los txhim kho lub neej kev pab cuam ntawm lub puab tsaig phaj, tab sis nws cov txheej txheem tsim khoom yog qhov nyuaj dua, yog li nws nyuaj rau kev tsim khoom.
Cov pa roj carbon tsawg alloy cam khwb cia hlau kuj yog cov khoom siv dav siv-resistant, vim tias nws cov hardness siab (≥45HRC) thiab tsim nyog toughness (≥15J / cm²), tuaj yeem tiv taus cov khoom txiav thiab rov ua dua extrusion los ntawm qaug zog spalling, yog li qhia tau zoo. hnav tsis kam. Nyob rau tib lub sijhawm, qhov nruab nrab carbon qis alloy cam khwb cia hlau kuj tuaj yeem hloov kho los ntawm cov txheej txheem kev sib xyaw thiab kev kho cua sov, kom lub hardness thiab toughness hloov tau ntau yam kom tau raws li cov kev xav tau ntawm kev ua haujlwm sib txawv. Qhov kev sim ua haujlwm qhia tau hais tias lub neej kev pab cuam ntawm cov pa roj carbon tsawg alloy steel lub puab tsaig phaj yog ntau tshaj 3 zaug ntev dua li ntawmsiab manganesehlau.
Cov lus qhia xaiv lub puab tsaig phaj:
Hauv cov ntsiab lus, kev xaiv cov khoom siv lub puab tsaig zoo tshaj plaws kom ua tau raws li qhov yuav tsum tau muaj ntawm cov tawv tawv thiab siab tawv, tab sis lub toughness thiab hardness ntawm cov khoom yog feem ntau contradictory, yog li nyob rau hauv lub tiag tiag xaiv ntawm cov ntaub ntawv, peb yuav tsum to taub tag nrho cov ua hauj lwm tej yam kev mob, tsim nyog. xaiv cov ntaub ntawv.
1) Kev cuam tshuam kev thauj khoom 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-tiv taus, qhov ntau lumpiness ntawm cov ntaub ntawv tawg, thiab qhov cuam tshuam ntau dua. Lub sijhawm no, hloov kho lossis dispersion-strengthened siab manganese hlau tseem tuaj yeem siv los ua cov khoom ntawm cov khoom xaiv. Rau nruab nrab thiab me crushers, qhov cuam tshuam los ntawm kev sib tsoo yooj yim tsis yog loj heev, kev siv cov hlau manganese siab, nws nyuaj rau ua kom nws ua haujlwm siab. Nyob rau hauv cov kev ua haujlwm zoo li no, kev xaiv ntawm nruab nrab carbon tsawg alloy steel lossis siab chromium cam khwb cia hlau / qis alloy steel cov khoom sib xyaw tuaj yeem tau txais txiaj ntsig zoo thiab kev lag luam.
2) Qhov sib xyaw ntawm cov khoom thiab nws cov hardness kuj tseem yog qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej hauv kev xaiv cov khoom tsim nyog. Feem ntau, qhov siab dua qhov hardness ntawm cov khoom, qhov siab dua qhov yuav tsum tau muaj hardness ntawm cov khoom ntawm ib qho yooj yim-rau-hnav, yog li nyob rau hauv cov xwm txheej ntawm ua tau raws li qhov yuav tsum tau toughness, cov khoom uas siab hardness yuav tsum tau xaiv kom deb li deb tau. .
3) Kev xaiv cov khoom tsim nyog yuav tsum tau xav txog kev hnav cov txheej txheem ntawm cov khoom hnav yooj yim. Yog hais tias qhov txiav hnav yog qhov tseem ceeb, qhov hardness yuav tsum tau txiav txim siab ua ntej thaum xaiv cov khoom. Yog hais tias hnav yas los yog qaug zog hnav yog lub ntsiab hnav, plasticity thiab toughness yuav tsum tau txiav txim siab ua ntej thaum xaiv cov khoom. Ntawm chav kawm, nyob rau hauv kev xaiv ntawm cov ntaub ntawv, nws yuav tsum tau xav txog lub rationality ntawm nws cov txheej txheem, yooj yim rau kev npaj ntau lawm thiab kev tswj kom zoo.
