Lub nraub qaum yob yog ib qho yob uas txhawb nqa kev ua haujlwmlub pob mov mogThiab yog qhov loj tshaj plaws thiab hnyav tshaj plaws yob siv nyob rau hauv rolling mills. Tuslub pob mov mogtuaj yeem pab txhawb nruab nrablub pob mov mogRau lub hom phiaj ntawm kev zam kev deflection ntawm kev ua haujlwm yob thiab cuam tshuam rau ntawm cov txiaj ntsig thiab kev ua tau zoo ntawm cov phaj thiab sawb dov zeb. Cov yam ntxwv zoo ntawm cov thaub qab thaub qab yog High Wardness thiab lub zog hardenity zoo thiab lub zog zoo thiab yob lub cev. Lub backup yob muaj siab hnav tsis kam thiab tev ua kom tsis kam, muaj zog tiv thaiv kev sib tsoo. Cov hlau forged steel yob ntawm 1000mm lossis tsawg dua yog ua los ntawm 86crMov7 thiab 9CR2MO. Nws cov ntsiab lus carbon yog 0.80% rau 0.95% thiab cov ntsiab lus cr yog 2% .IT siv tau rau qee cov mills me me. CR4 thiab CR5 rov qab yob muaj cov ntsiab lus carbon muaj ntawm 0.4% mus rau 0.6% thiab 5%, haum rau qib high-ceev steel ua haujlwm yob.

Rau qee cov mills me me, cov forged steel backup yob ntawm 1000mm lossis tsawg dua yog ua los ntawm 86Cr2mo, nws cov peev txheej carbon thiab 0.95% thiab cov ntsiab lus craseces yog 2%.
Cov hlau rau CR4 thiab CR5 Backup Rolls muaj cov ntsiab lus carbon ntawm 0.4% mus rau 0.6% thiab cov ntsiab lus ntawm 4% mus rau 5%. Lub hardened, hnav tsis kam, tev ua kom tsis taus, nkees-resistant thiab anti-huam yuaj ntawm cov ntaub qhwv ntsej muag ntawm lub yob lub cev thiab yob tawm ntawm kev sib tsoo. CR4, CR5 Backup Rolls yog qhov tsim nyog rau high-ceev steel thiab semi-high-ceev steel ua haujlwm yob.

Cov yam ntxwv ntawm High-ceev steel yob (hss yob)

1. High-ceev steel yob cov ntaub ntawv muaj cov ntaub ntawv loj xws li Vanadium, Tungsten, chromium, molybdenum, thiab niobium. Cov hom carbides hauv yob qauv yog MC thiab M2C. Muab piv nrog cov hlau colls nrog cov npib tsib xee-chromium rolls, txhim kho lub sij hawm ntawm lub sijhawm hloov, txhim kho cov nqi kev ua haujlwm zoo thiab txo cov nqi tsim khoom.

2. Kev ceev-ceev steel yob muaj zoo thermal stability. Ntawm lub yob kom sov, lub yob nto muaj ntau dua hardness thiab zoo hnav tsis kam.
High-ceev steel yob muaj cov khoom siv tawv zoo, thiab lub cev muaj zog tsis tshua muaj nuj nqis, yog li ua haujlwm tau muaj sib npaug zoo los ntawm sab nraud rau sab hauv.

3. Thaum siv cov hlau ceev rolls, nyob rau hauv cov kev mob txias, ib qho nyias nyias thiab ntom duab yeeb yaj kiab. Qhov kev hnav khaub ncaws no, cov yeeb yaj kiab nyias thiab ntom nti uas tsis muaj lub sijhawm ntev uas tsis tau poob, ua kom cov neeg ceev nrawm ua kom muaj zog dua.

4. Kev ceev-ceev steel yob muaj cov khoom siv loj nthuav cov coefficient thiab zoo thermal conductivity. Cov HSS yob txuas ntxiv mus rau hauv kev txiav vim yog nthuav dav ntawm cov ntaub ntawv ceev steel uas lawv tus kheej. Thaum lub sij hawm rolling, qhov kev hloov ntawm cov zawj yob yog me, thiab kev sib xws ntawm lub qhov bar lossis rebar, uas yog qhov ntau dua rau kev tswj hwm qhov tsis zoo rau kev thev taus.
5. Tus tub ntxhais ntawm centrifugally cam khwb cia high-ceev steel yob yog ua los ntawm alloy catoy zog yog muaj zog.
