Kev sib tsom tawm xov pob khoom txuj ci thiab daim teb daim ntawv thov

Lub luag hauj lwm tseem ceeb ntawm kev sib tsom tawm pob yog muab cov khoom siv, uas yog qhov khoom qub rau ib hom kev sib tsoo nruab nrab, feem ntau yog hais txog lub pob zeb siv rau kev sib tsoo cov khoom ntawm kev sib tsoo tshuab. Kev sib tsoo cov khoom sib npaug muaj ntau hom khoom sib xws, xws li cov khoom tawg pob zeb, cov hlau steel forged, cov khoom tawg hlau, kev sib tw steel hlau, thiab cov zoo li.

1. Kev npaj txoj kev sib tsoo tawm pob zeb:

Ntawm qhov tam sim no, feem ntau yog siv ntau tshaj xov xwm npas yog feem ntau qis-chromium hlau npas, uas yog qhov tseem ceeb sib tsoo lub cev hauv pob mills. Tsawg-chromium npas yog tsim los ntawm cov khoom ua kom sov muaj cua txias, hlau pwm, los yog xuab zeb casting, thiab feem ntau hu ua qes-chromium hlau casting npas.

2, kev sib tsoo tawm kev sib tsoo steel pob qauv:

Yuav kom paub tseeb tias siv cov txiaj ntsim tau zoo, nws yog qhov tsim nyog los xyuas kom meej tias cov khoom sib tsoo ntawm kev sib tsoo tuaj yeem ncav ib qho qauv zoo. Ua ntej tshaj plaws, thaum txiav txim tias nws yog looj, qhov tseem ceeb tshaj plaws rau kev txiav txim siab yog qhov kev ua kom pom kev nyuaj. Rockwell hardness tester yuav siv tau los xyuas txog qhov nyuaj. Kev xyaum tau pom tau hais tias lub neej ntawm cov khoom tawg ntawm HRC60 ntau tshaj ob zaug ntawm HRC40-50. Cov pob zeb tsawg-chromium hais txog pob hlau nrog cov ntsiab lus ntawm chromium tsawg dua 3.0% thiab cov ntsiab lus ntawm cov khoom nruab nrab ntawm 1.80% thiab 3.30%. Tsis tshua muaj chromium pob hardness yuav tsum yog siab tshaj 45 degree, yog tias koj tau txais kev pab ntawm kev siv cov lus qis tsis tshua zoo siab yuav tsum siv los kho cov tshuaj kub los yog kev tswj kev laus. Yog tias qhov kev xeem tawv (HRC) tsawg dua 40 degree, nws qhia tau hais tias lub pob chromium tsawg tsawg dua los yog dhau los.

3, sib tsoo tawm ntawv pob ntawv pob:

Tam sim no, qhov sib tsoo tawm pob zeb tau siv dav. Cov koom txoos muaj xws li: metallurgy thiab mining, cement tsev cov ntaub ntawv, cov ntoo tshauv, thermal fais fab, cov pa roj carbon dioxide, cov khoom siv hlau nplaum, cov khoom lag luam, cov dej khov, cov pob zeb, cov paug, ultrafine hmoov, calcium carbonate, quartz xuab zeb thiab lwm yam lag luam.
