Lub luag haujlwm ntawm lub phaj hnav yog dab tsi?
Taw qhia:
Cov phaj hnav, tseem hu ua hnav liner lossis hnav ncoo, yog ib qho tseem ceeb hauv kev siv ntau yam kev lag luam. Nws yog tsim los tiv thaiv huab cua phem thiab tiv thaiv lub hauv paus qauv ntawm hnav thiab puas. Hauv tsab xov xwm no, peb yuav tshawb txog cov haujlwm, hom, cov ntaub ntawv, thiab kev siv ntawm cov phaj coj.
Kev Ua Haujlwm ntawm Hnav Plate:
1. Kev tiv thaiv kev puas tsuaj: Ib qho ntawm cov haujlwm tseem ceeb ntawm cov phaj hnav yog los tiv thaiv cov khoom siv hauv qab lossis cov qauv ntawm kev hnav tsis zoo. Nws ua raws li ib tug sacrificial txheej uas yuav siv sij hawm lub brunt ntawm hnav, kom ntseeg tau lub ntees ntawm cov khoom.
2. Impact resistance: Hnav daim hlau feem ntau raug cuam tshuam los ntawm cov khoom poob los yog cov tshuab hnyav. Lawv nqus thiab faib cov zog no, tiv thaiv kev puas tsuaj rau cov qauv thiab txuas ntxiv nws txoj sia.
3. Kev tiv thaiv corrosion: Qee qhov kev lag luam thiab ib puag ncig muaj kev cuam tshuam corrosion, uas tuaj yeem ua rau cov qauv thiab cov khoom siv tsis muaj zog thaum lub sijhawm. Hnav daim hlau ua los ntawm cov khoom siv tiv thaiv corrosion muab kev tiv thaiv kev tiv thaiv, tiv thaiv cov tshuaj tiv thaiv thiab ua kom lub neej ntev ntawm cov khoom siv.
4. Kev txo qhov hnyav: Hauv kev lag luam uas qhov hnyav yog qhov kev txhawj xeeb, hnav daim hlau ua los ntawm cov khoom siv hnyav muaj txiaj ntsig ntxiv. Los ntawm kev siv cov phiaj no, tag nrho qhov hnyav ntawm cov cuab yeej tuaj yeem txo qis yam tsis muaj kev cuam tshuam rau lub zog lossis kev ua haujlwm ntev.
Hom Hnav Plates:
1. Chromium carbide overlay daim hlau: Cov phaj hnav no muaj cov hlau puag, feem ntau yog cov hlau me me, thiab txheej ntawm chromium carbide alloy tso rau saum. Lawv muaj kev tiv thaiv zoo heev, cuam tshuam tsis kam, thiab zoo haum rau qhov chaw kub kub.
2. Hardox hnav daim hlau: Hardox yog hom hnav phaj tsim los ntawm SSAB. Cov phaj no paub txog lawv qhov tshwj xeeb hardness thiab toughness. Lawv zoo tagnrho rau cov ntawv thov uas cuam tshuam hnyav thiab zawv zawg abrasion, xws li cov khoom siv mining thiab pob tseg lub cev.
3. Ceramic coj daim hlau: Ceramic coj daim hlau yog tsim los ntawm cov vuas luaj ceramic uas txuas nrog cov roj hmab los yog hlau rov qab. Lawv muab kev puas tsuaj zoo heev thiab cuam tshuam, ua rau lawv haum rau cov cheeb tsam uas muaj qib siab hnav.
4. Tungsten carbide coj daim hlau: Tungsten carbide hnav daim hlau yog dav siv hauv kev lag luam xws li mining, kev tsim kho, thiab kev ua liaj ua teb. Lawv muaj zog heev thiab tuaj yeem tiv taus hnyav hnyav, yaig, thiab cuam tshuam.
Cov ntaub ntawv siv hauv cov phaj hnav:
1. High-strength steel: High-strength steel coj daim hlau yog feem ntau siv nyob rau hauv daim ntawv thov uas yuav tsum tau muaj zog thiab tej yam kuj. Lawv zoo tagnrho rau kev lag luam xws li kev tsim kho, mining, thiab kev ua liaj ua teb.
2. Chromium carbide: Chromium carbide hnav daim hlau muaj lub siab tawv thiab tiv taus kev puas tsuaj, cuam tshuam, thiab corrosion. Lawv feem ntau siv rau hauv cov ntawv thov uas yuav tsum hnav hnyav, xws li chutes, hoppers, thiab thoob.
3. Ceramic: Ceramic hnav daim hlau yog tsim los ntawm cov ntaub ntawv xws li alumina, zirconia, lossis silicon carbide. Cov ceramics no zoo heev hardness thiab resistant rau hnav, tshav kub, thiab kev cuam tshuam.
4. Roj Hmab: Roj hmab hnav daim hlau yog siv rau hauv cov ntawv thov uas txo cov suab nrov thiab kev co damping yog qhov tseem ceeb. Lawv muab kev cuam tshuam zoo heev thiab yoog raws.
Daim ntawv thov ntawm Wear Plates:
1. Kev lag luam mining: Hnav daim hlau pom kev siv dav hauv kev lag luam mining los tiv thaiv cov thoob, crusher liners, thiab cov ntxaij vab tshaus los ntawm kev hnav thiab tsim kua muag los ntawm cov khoom siv abrasive.
2. Kev tsim kho kev lag luam: hnav daim hlau yog siv rau hauv cov khoom siv, xws li excavator thoob, bulldozer blades, thiab pob zeb sib tov nruas, kom tiv taus qhov hnyav ntawm qhov chaw tsim kho thiab tiv thaiv kev hnav ntxov ntxov.
3. Cement kev lag luam: Hnav daim hlau yog ua hauj lwm hauv cov cement nroj tsuag los tiv thaiv cov cuab yeej xws li crushers, hoppers, thiab chutes los ntawm abrasive nkaus ntawm raw cov ntaub ntawv xws li limestone thiab clinker.
4. Kev lag luam ua liaj ua teb: Hnav daim hlau yog siv rau hauv cov tshuab ua liaj ua teb xws li plows, tillers, thiab sib txuas cov hniav sib dhos. Lawv muab kev tiv thaiv kev hnav los ntawm kev sib cuag nrog pob zeb, pob zeb, thiab av.
5. Kev lag luam tsim hluav taws xob: Hnav cov phaj yog siv rau hauv thermal fais fab nroj tsuag los tiv thaiv boilers, chutes, thiab deflectors los ntawm erosive los ntawm thee, biomass, thiab tshauv hais.
Xaus:
Cov phaj hnav ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv thiab cov qauv ntawm kev hnav, cuam tshuam, thiab corrosion. Nws ua raws li cov ntaub thaiv npog, ua kom lub neej ntev thiab kev ua haujlwm ntawm cov khoom siv. Nrog rau ntau hom thiab cov ntaub ntawv muaj, hnav daim hlau tuaj yeem ua raws li cov ntawv thov tshwj xeeb, ua rau lawv yog ib qho tseem ceeb hauv ntau qhov kev lag luam.
