S690Q S690QL S690QL1 High Strength Steel Ntau Lawm Txheej Txheem:
S690Q / S690QL / S690QL1 steel daim hlau yog txhua yam tsim los ntawm quenched thiab tempered (Q + T) kev kho cua sov. Tag nrho cov txheej txheem tsim khoom muaj cov theem tseem ceeb hauv qab no:
1. Smelting thiab Refining
Cov txheej txheem txheej txheem: Kub hlau pretreatment → BOF steelmaking → LF ladle refining → VD / RH nqus degassing.
Kev sib sib zog nqus desulfurization yog ua los ntawm KR kub hlau pretreatment kom muaj cov ntsiab lus tsis tshua muaj leej faj hauv cov hlau molten. BOF steelmaking enables meej tswj cov pa roj carbon, phosphorus thiab lwm yam khoom. LF refining thiab nqus degassing ntxiv purify molten steel, tshem tawm cov pa phem thiab cov khoom siv, thiab lav zoo siab steel huv.
2. Casting thiab Slab Production
Refined molten steel yog cam khwb cia rau hauv slabs ntawm nruam casting (los yog ingot casting). Nruam cam khwb cia slabs undergo qeeb txias rau 24-60 teev, ua raws li slab tshuaj xyuas thiab txais.
3. Kub Rolling
Slabs tau ua tiav rau hauv daim hlau los ntawm cua sov → descaling → tswj dov → ACC ceev cua txias → straightening. Tswj dov thiab txias tshuab yog siv thaum dov. Kev tswj xyuas qhov tseeb ntawm dov kub thiab txias tus nqi refines grain qauv thiab optimizes metallurgical microstructure. Txias txias thiab tshuaj xyuas saum npoo yog nqa tawm tom qab dov.
4. Quenched & Tempered Thaum tshav kub kub kho
Qhov no yog cov txheej txheem tseem ceeb kom ua tiav lub zog ntawm 690 MPa. Cov phaj yog raug rau quenching thiab tempering kho:
- Quenching: Cov phaj yog rhuab mus rau austenitizing kub (kwv yees . 800℃) ces sai sai dej-cooled los ua high-strength martensitic los yog bainitic microstructure.
- Tempering: Rov ua kom sov thiab tuav ntawm qhov kub thiab txias (kwv yees . 620}℃) txhawm rau txo qis kev ntxhov siab thiab txhim kho toughness thiab ductility.
5. Ua tiav thiab tshuaj xyuas
Tom qab kev kho cua sov: xov → txiav & sampling → mechanical property test → ultrasonic test → marking → warehousing. Kev tshuaj xyuas zoo suav nrog cov xwm txheej saum npoo av, qhov ntev ntev, kev muaj tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab thiab lwm yam ntsuas kom ua tau raws li EN 10025-6 cov cai.
