Dab tsi yog kev tsim cov txheej txheem ntawm weathering steel phaj?
Weathering steel, uas yog, atmospheric corrosion-resistant steel, yog ib tug tsawg-alloy steel series ntawm zoo tib yam hlau thiab stainless hlau. Huab cua-resistant daim hlau yog ua los ntawm cov pa roj carbon zoo tib yam nrog ib tug me me ntawm tooj liab, npib tsib xee thiab lwm yam corrosion-resistant ntsiab ntxiv. Cov huab cua tsis kam yog 2 npaug ntawm cov pa roj carbon zoo tib yam. ~ 8 zaug, thiab cov xim pleev xim yog 1.5 ~ 10 npaug ntawm cov pa roj carbon zoo tib yam.
Weathering steel phaj feem ntau txais yuav cov txheej txheem ntawm kev them cov khoom zoo rau hauv lub cub tawg - smelting (converter, hluav taws xob rauv - microalloying kho - argon tshuab - LF refining - qis superheat nruam casting (feem tsawg lub ntiaj teb hlau) - tswj dov thiab tswj cua txias. smelting, scrap steel yog ntxiv rau hauv lub cub tawg ua ke nrog cov nqi, thiab yog smelted raws li cov txheej txheem ib txwm, tom qab tapping, deoxidizer thiab alloy yog ntxiv. Tempered los ntawm argon tshuab yog cam khwb cia rau hauv slabs los ntawm ib tug nruam casting tshuab.Vim hais tias los ntawm kev ntxiv lub ntiaj teb tsis tshua muaj ntsiab lus rau cov hlau, lub weathering steel phaj yog purified thiab cov ntsiab lus inclusion yog heev txo.
