1, Dab tsi yog cov khoom ntawm hnav phaj
Cov phaj hnav-tiv taus yog hlau, thiab nws cov khoom tseem ceeb yog cov pa roj carbon tsawg thiab cov txheej txheem hnav-tiv taus, nyob rau hauv uas cov alloy hnav-resistant txheej nyiaj rau 1/2 ~ 1/3 ntawm tag nrho cov phaj tuab; Vim tias cov tshuaj muaj pes tsawg leeg tseem ceeb yog chromium, uas tuaj yeem ncav cuag 20% ~ 30% ntawm cov ntsiab lus ntawm tag nrho cov ntaub ntawv, nws hnav tsis kam yog qhov zoo heev.
2, Cov yam ntxwv ntawm hnav phaj
1. Impact resistance: Qhov cuam tshuam tsis kam ntawm lub phaj hnav-resistant yog zoo heev. Txawm hais tias muaj kev poob qis heev hauv cov txheej txheem ntawm kev xa khoom, nws yuav tsis ua rau muaj kev puas tsuaj ntau dhau rau cov phaj hnav-resistant.
2. Thaum tshav kub kub tsis kam: Feem ntau, hnav daim hlau hauv qab 600 ℃ tuaj yeem siv tau ib txwm. Yog tias peb ntxiv qee qhov vanadium thiab molybdenum thaum ua daim hlau, ces qhov kub siab tshaj 800 ℃ tsis muaj teeb meem.
3. Corrosion tsis kam: Cov phaj hnav muaj ntau cov chromium, yog li qhov corrosion kuj ntawm cov phaj hnav zoo heev, thiab tsis tas yuav txhawj txog corrosion.
4. Tus nqi kev ua tau zoo: tus nqi ntawm cov phaj coj yog 3-4 npaug ntawm cov phaj hlau zoo tib yam, tab sis kev pabcuam lub neej ntawm cov phaj phaj yog 10 npaug ntev dua li ntawm cov phaj hlau zoo tib yam, yog li nws cov nqi kev ua tau zoo yog qhov siab.
5. Kev ua haujlwm yooj yim: lub weldability ntawm lub phaj hnav-resistant yog qhov muaj zog heev, thiab nws tuaj yeem yooj yim khoov rau hauv ntau yam duab, uas yooj yim heev rau kev ua.
3 、 Daim ntawv thov ntawm hnav phaj
Nyob rau hauv ntau lub hoobkas, hnav daim hlau yog siv los ua conveyor siv. Vim tias lawv cov kev cuam tshuam muaj zog, lawv yuav tsis deform txawm tias qhov siab sib txawv ntawm cov khoom thauj khoom loj heev. Ntxiv mus, vim lawv cov corrosion kuj zoo, lawv muaj peev xwm tuav tau ib tug zoo kev pab cuam lub neej txawm yog dab tsi yog conveyed.
