Ribbed steel bar ntau lawm kab ua tiav txheej txheem
Cov txheej txheem tseem ceeb thiab cov khoom siv ntawm cov kab ntau lawm
1. Kev npaj cov khoom nyoos
Cov khoom siv raw: Billets tsim los ntawm kev nruam nruam, nws cov tshuaj muaj pes tsawg leeg (xws li, carbon, manganese, silicon, thiab lwm yam) nruj me ntsis raws li cov qauv qib rebar.
Chaw thau khoom: Billets tau muab tso rau hauv lub qhov cub cua sov kom zoo ntawm cov saw of elevator lossis taug kev nqaj.
2. Cua sov
Khoom siv: Ib qho kev taug kev beam cua sov rauv yog feem ntau siv.
Lub hom phiaj: Txhawm rau kom sov lub billet mus rau qhov kub austenitic thaj tsam li ntawm 1050-1200 degree, muab cov yas zoo thiab ua kom yooj yim deformation thaum dov.
3. Rolling - Lub plawv ntawm cov kab ntau lawm
Cov txheej txheem dov feem ntau muab faib ua ntau theem. Rollers teem nyob rau hauv roughing, nruab nrab, thiab xov mills maj mam txo cov billet mus rau lub hom phiaj rebar txoj kab uas hla, tsim nto ribs nyob rau hauv tus txheej txheem.
- Lub tshuab roughing ua qhov pib txoj kab uas hla ntawm cov loj -section steel billets.
- Qhov nruab nrab dov zeb ntxiv txo txoj kab uas hla ntawm cov khoom dov, nqa nws tus ntoo khaub lig-sectional duab los ze zog rau cov khoom tiav.
- Lub tshuab ua tiav yog cov kauj ruam tseem ceeb hauv kev tsim cov txheej txheem kawg. Ntawm no, cov khoom dov dhau los ntawm qhov tshwj xeeb grooved xov zeb sawv ntsug. Cov rolls yog engraved nrog grooves sib haum mus rau rib qauv ntawm steel bar, yog li tsim transverse thiab longitudinal tav rau saum npoo ntawm steel bar.
4. Thermomechanical Rolling - Cov txheej txheem tseem ceeb
Niaj hnub nimno siab -lub zog rebar (xws li HRB400E thiab HRB500E) feem ntau siv kev sib xyaw ua ke ntawm cov hluav taws kub quenching thiab autotempering.
Cov txheej txheem: Tom qab tawm hauv lub tshuab tiav, cov rebar nkag mus rau qhov siab - dej ua haujlwm - los ntawm chav tsev txias, ua kom txias sai sai rau cov txheej txheem saum npoo los ua ib qho nyuaj martensite thaum lub hauv paus tseem kub.
Autotempering: Tom qab tawm hauv chav txias, cua sov los ntawm cov tub ntxhais sai sai dissipates sab nraud, "tempering" txheej martensite rau ntawm qhov chaw, tsim kom muaj ib tug tempered bainite qauv nrog zoo tag nrho cov khoom.
Qhov zoo: Txhim kho lub zog thiab toughness ntawm lub rebar yam tsis muaj los yog nrog tsawg ntxiv ntawm cov khoom kim heev alloying.
5. Tiav thiab sau
Txias Txias: Tso cai rau cov cua txias kom ua haujlwm zoo thiab txias ntxiv rau chav sov thaum tiv thaiv kev khoov.
Txias Shearing: Txiav ntev rebar rau hauv qhov ntev (piv txwv li, 9m lossis 12m).
Straightening: Ib tug straightener tshem tawm qhov khoov uas tshwm sim thaum lub caij txias thiab kev thauj mus los.
Sau thiab Bundling: Yeej suav thiab sau cov rebar, tom qab ntawd siv lub baler los ntim rau hauv cov pob khoom kom yooj yim thauj thiab khaws cia.
