Thaum muaj kev sib txhuam hnyav, kev cuam tshuam thiab kev ua haujlwm hnyav hauv kev lag luam mining, cement, hlau thiab kev tuav cov khoom siv, kev xaiv cov hlau sib xyaw ua ke zoo uas tiv taus kev hnav yuav cuam tshuam ncaj qha rau lub neej ua haujlwm ntawm cov khoom siv, tus nqi txij nkawm thiab kev ua haujlwm zoo tag nrho. Ntau tus neeg yuav khoom tsuas yog piv cov nqi thiab tsis quav ntsej txog cov khoom siv tseem ceeb, uas yooj yim ua rau cov phaj tawg ua ntej lub sijhawm, tev tawm thiab hnav tsis ua haujlwm. Hauv qab no peb piav qhia txog cov yam ntxwv tseem ceeb los pab koj txiav txim siab yuav khoom zoo.
1. Qhov nyuaj ntawm cov txheej hnav
Qhov tawv yog qhov qhia tau yooj yim tshaj plaws rau cov hlau sib xyaw uas tiv taus kev hnav. Cov txheej txheem sib xyaw ua ke hardfacing yog tsim los ntawm kev vuam ntawm cov hlau carbon hauv paus. Cov qib tawv feem ntau yog HRC 55–62. Qhov tawv ruaj khov txhais tau tias kev ua haujlwm tiv thaiv kev sib txhuam tas li. Tsis txhob siv cov khoom uas muaj qhov tawv tsis sib xws; qhov tawv qis hauv zos yuav ua rau cov khoom poob sai.

2. Kev sib txuas ntawm cov hlau nplaum thiab cov phaj puag zoo
Ib daim phaj uas tsim nyog ua tiav kev sib txuas ntawm cov hlau nplaum tawv thiab cov hlau tsis muaj zog. Kev sib txuas zoo tiv thaiv kev tawg thaum raug cuam tshuam ntau zaus. Kev sib txuas tsis zoo yuav ua rau txheej hnav tawm thaum raug cuam tshuam los ntawm cov khoom loj xws li hlau thiab thee.

3. Hnav kev ua haujlwm tsis kam
Kev tiv thaiv kev sib txhuam yog qhov tseem ceeb. Nws raug sim los ntawm kev sim kev hnav khaub ncaws abrasive. Nyob rau hauv tib qho xwm txheej ua haujlwm, cov phaj uas muaj kev tiv thaiv kev hnav khaub ncaws zoo heev tuaj yeem ntev lub neej kev pabcuam 3-8 zaug piv rau cov phaj hlau manganese ib txwm muaj. Kev tiv thaiv kev hnav khaub ncaws muaj feem cuam tshuam nrog cov khoom sib xyaw, xws li cov ntsiab lus chromium carbide.
Lo lus tseem ceeb:chromium carbide hnav phaj
4. Kev cuam tshuam tsis kam
Muaj ntau tus neeg tsis nkag siab txog qhov nyuaj siab nrog rau qhov tsis yooj yim rau kev cuam tshuam. Qhov nyuaj siab feem ntau ua rau muaj kev tawg yooj yim. Cov hlau sib xyaw ua ke zoo uas tiv taus kev hnav sib npaug qhov nyuaj thiab kev tawv. Nws tuaj yeem tiv taus qhov cuam tshuam nruab nrab los ntawm cov pob zeb poob yam tsis tawg. Yog tias koj qhov chaw muaj kev cuam tshuam hnyav, peb yuav tsum kho cov mis alloy raws li qhov tsim nyog.
5. Kev ua tau zoo
Cov phaj zoo txhawb nqa kev txiav, khoov, tho thiab vuam rau kev teeb tsa ntawm qhov chaw. Qee cov phaj tsis zoo yuav tawg yooj yim thaum txiav lossis khoov. Kev ua haujlwm tau zoo yog qhov tseem ceeb rau kev tsim cov chute, hopper thiab crusher liner.
Lo lus tseem ceeb:lub tshuab crusher liner
6. Kev ruaj khov ntawm pawg
Kev sib xws ntawm cov khoom ib pawg mus rau ib pawg yog qhov tseem ceeb heev rau kev yuav khoom ntau mus sij hawm ntev. Cov chaw tsim khoom txhim khu kev qha tswj hwm cov khoom siv raw thiab cov yam ntxwv ntawm cov khoom siv. Txhua pawg yuav muab cov ntawv qhia COA rau kev sim rau qhov nyuaj thiab cov tshuaj lom neeg. Cov pawg tsis ruaj khov ua rau muaj kev pheej hmoo ntawm lub sijhawm tsis ua haujlwm uas tsis paub tseeb.
Lo lus tseem ceeb:hlau vuam hardfacing
7. Kev Tshuaj Xyuas & Daim Ntawv Pov Thawj
Thov nug cov ntawv pov thawj ua ntej yuav khoom ntau. Kev kuaj qhov nyuaj, kev tshuaj xyuas metallographic thiab cov ntaub ntawv kuaj kev hnav tuaj yeem txheeb xyuas qhov ua tau zoo tiag tiag, es tsis txhob tsuas yog cia siab rau cov lus piav qhia ntawm tus neeg muag khoom xwb.
Kev Txheeb Xyuas
Yuav kom xaiv tau cov hlau sib xyaw ua ke uas tiv taus kev hnav zoo, tsis txhob txiav txim los ntawm tus nqi xwb. Soj ntsuam qhov nyuaj, lub zog sib txuas, kev hnav tsis kam, kev cuam tshuam, kev ua haujlwm thiab kev ruaj khov ua ke. Qhia rau peb paub txog koj qhov xwm txheej ua haujlwm, cov khoom siv abrasive, qib kev cuam tshuam thiab qhov loj ntawm cov hlau, peb tuaj yeem pom zoo cov hlau chromium carbide hnav tsis kam rau koj qhov project.
