Cov qauv kev ntseeg tau zoo dua
Fine grain lug txhim kho lub toughness thiab durability ntawm reinforcement steel.
Cov txiaj ntsig no piav qhia vim li cas ntau tus neeg tsim khoom hlau thoob ntiaj teb tso siab rauFeV50 ferrovanadium rau kev tsim steel ntau lawm.
Ntiaj teb no thov rau Vanadium Microalloyed Rebar
Vanadium microalloying tshuab tau dav siv los ntawm cov neeg tsim khoom steel hauv cov tebchaws xws liTuam Tshoj, Is Nrias teb, thiab Russia, qhov twg cov phiaj xwm loj loj ua rau muaj kev xav tau siab - lub zog txhawb nqa steel.
Raws li kev lag luam qhia, kev tsim kho sector suav rauTshaj li 40% ntawm kev siv vanadium thoob ntiaj teb. Ntau qhov kev thov no ncaj qha txuas rau kev siv FeV50 ferrovanadium hauv rebar ntau lawm.
Raws li kev txhim kho infrastructure txuas ntxiv mus thoob ntiaj teb, qhov kev thov rauvanadium microalloyed rebar hlaucia siab tias yuav nyob ruaj khov.
