Kev npaj txuj ci thiab txheej txheem cov txheej txheem ntawm kev sib tsoo steel pob

Kev sib tsoo steel pob yog hais txog lub pob steel siv los zom cov khoom siv ntawm lub zeb, uas yog qhov tseeb yog ib hom kev sib tsoo lub cev. Cov neeg kho mob hauv qab no thiab txhua tus neeg luv luv qhia cov txheej txheem kev npaj thiab cov txheej txheem kev sib tsoo cov pob steel.

Npaj:

Tsawg chromium steel pob yog qhov tseem ceeb tshaj plaws kev sib tsoo lub cev nyob rau hauv pob mills, thiab nws yog hu ua sib tsoo steel pob txawv teb chaws. Tsawg-chromium steel npas raug tsim los ntawm nruab nrab cov hluav taws xob ua kom sov, hlau pwm lossis xuab zeb casting. Yog li no, cov neeg lag luam hauv tsev ntawm cov khoom siv tiv taus hnav cov khoom siv feem ntau hu ua low-chromium alloy cam khwb cia khoom.

Cov qauv kev:

1. Seb cov sib tsoo steel pob hnav-resistant, cov ntaub ntawv tseem ceeb tshaj plaws yog kuaj qhov nyuaj, uas tuaj yeem kuaj los ntawm Rockwell hardness tester. Kev xyaum ua pov thawj pom tau tias kev pab cuam lub neej ntawm steel npas saum HRC60 yog ntau dua ob zaug ntawm HRC40-50.

2. Cov qib qis chromium steel npas xa mus rau cov npas steel nrog cov ntsiab lus chromium ≤ 3.0% thiab cov ntsiab lus carbon ntawm 1.80% thiab 3.30%. Txhua tus yog cov khoom me me chromium. Lub teb chaws tus qauv hais tias qhov tsawg kawg chromium pob hardness (HRC) yuav tsum be 45 degrees. Yog tias qhov zoo ntawm cov khoom siv chromium tsawg kawg yog qhov kev lees paub, kev kho cua sov thiab huab cua sov lossis kev vibration lub hnub nyoog yuav tsum tau saws. Yog tias qhov kev xeem qhov hardness (HRC) qis dua 40 degrees, nws txhais tau hais tias lub pob me me chromium pob hardness tsis txaus los yog kub siab dhau tshwm sim.

Qhov saum toj no yog kev qhia ntawm kev npaj ua thiab txheej txheem txheej txheem ntawm kev sib tsoo steel pob, Kuv vam tias nws yuav pab tau txhua tus.
