Nrog rau txoj kev loj hlob sai ntawm kev lag luam crusher, crusher manufacturers tab tom nrhiav rau kev txhim kho tshiab thiab cov tswv yim tshiab, thiab qhov hnav-tiv taus ntawm crusher crusher rauj taub hau tau dhau los ua lub hom phiaj tseem ceeb. Piv txwv li, rauj lub taub hau ntawm rauj crusher yog qhov yooj yim rau hnav thiab hnav, uas yog ib qho yooj yim ua rau hnyav hnyav hauv cov txheej txheem ua haujlwm, uas yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv. Txhawm rau ntxiv dag zog rau kev ua haujlwm ntawm rauj lub taub hau ntawm lub crusher, rauj manufacturers yog tas li innovating. Xaiv cov khoom siv chromium alloy siab rau cam khwb cia crusher rauj tuaj yeem ua rau cov khoom hnav-tiv taus.
Crusher rauj yog ib qho yooj yim rau hnav qhov chaw, thaum hnav hnyav yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv, yog li xaiv rauj ntawm cov khoom siv chromium alloy siab. High chromium alloy muaj qhov hnav tsis zoo vim nws qhov hnyav hnyav thiab ua haujlwm tawv tawv ntawm qhov chaw nyob rau hauv lub siab extrusion siab lossis cuam tshuam. Txawm li cas los xij, lub crusher rauj ua los ntawm high chromium alloy tsis haum rau crushing ntawm ib yam khoom. Lub hardness ntawm tsawg chromium alloy yog xws li crushing ntawm thee. Kev ua tau zoo ntawm cov chromium alloy siab tsis tuaj yeem ua si tag nrho, thiab nws yuav yooj yim heev rau hnav zoo li cov ntaub ntawv tsis tshua muaj zog, ua rau muaj qhov tshwm sim ntawm lub neej luv luv ntawm lub rauj.
Nws tuaj yeem pom tias lub crusher rauj ua los ntawm high chromium alloy kuj muaj qhov zoo thiab qhov tsis zoo. Thaum xaiv cov khoom siv crusher, cov neeg siv yuav tsum xaiv qhov tsim nyog rau lawv tus kheej, txhawm rau ua si nws qhov kev ua tau zoo mus rau qib siab dua thiab txhim kho kev ua haujlwm ntawm cov khoom siv.
Muaj ntau ntau hom kev annealing rau hnav-resistant rauj castings, nrog rau ua tiav annealing thiab tsis tiav annealing. Qhov txawv ntawm ob txoj kev yog dab tsi?
Kev ua tiav ntawm kev hnav-tiv taus rauj yog kom sov cov cam khwb cia hlau mus rau qhov ntsuas kub, thiab maj mam txias nws tom qab ua tiav austenitizing kom tau txais cov qauv sib luag. Nws yog ib txoj kev annealing los hloov cov qauv qub thiab cov khoom. Ua kom tiav annealing yog feem ntau annealing txoj kev los txhim kho cov microstructure ntawm carbon steel thiab tsawg alloy steel, los yog kom soften nws kom deb li deb tau los txhim kho cov yas workability thiab machinability. Yog hais tias peb tsuas hais annealing, peb feem ntau xa mus rau ua kom tiav annealing. Tsawg carbon steel thiab hypereutectosis tsis haum rau ua kom tiav annealing. Lub hardness ntawm tsawg carbon steel castings tom qab annealing yog tsawg, uas yog tsis conducive rau txiav. Qhov thib ob cementite nag lossis daus ntawm hypereutectoid steel castings thaum lub sij hawm cua sov thiab qeeb txias annealing tuaj yeem txo lub zog, plasticity thiab cuam tshuam rau lub zog ntawm castings. Qhov tsis tiav annealing ntawm hnav-resistant rauj yog recrystallize lub microstructure ntawm cov castings ntawm engineering steel, low-alloy steel thiab nruab nrab carbon structural steel los ntawm kev ua tiav annealing, uas ua rau cov nplej ntawm cov castings zoo thiab microstructure uniform, thiab ua rau lub microstructure. nyuaj tsim.
