Txhawm rau muab kev ua si tag nrho rau lub zog siab, siab tawv, kev tiv thaiv corrosion thiab hnav tsis kam ntawm titanium, tsim thiab txuas ntxiv rau cov khoom siv muaj txiaj ntsig zoo ntawm lub nraub qaum-kawg, thiab tsim ua tiav cov saw hlau ua ke "peev txheej-khoom-kev lag luam" , Ansteel Group Pansteel, koom tes nrog Beijing Iron thiab Steel Research Institute, Chongqing University, Northeastern University thiab lwm lub koom haum tshawb fawb tshawb fawb, tsis ntev los no tau tsim ib hom tshiab ntawm titanium alloyed hnav-resistant steel, tsim ntsuab thiab tsis tshua muaj nqi npaj tshuab rau titanium. alloyed hnav-resistant steel, hloov qhov uas twb muaj lawm "hluav taws xob rauv-tuag casting-forging" txheej txheem kev npaj nrog tus nqi qis "converter-nruam casting-rolling", qhib txoj hauv kev tshiab rau daim ntawv thov ntawm cov khoom siv titanium.
Pab pawg neeg ua haujlwm tau maj mam tawg los ntawm ntau qhov teeb meem tseem ceeb uas cuam tshuam qhov nruam casting ntau lawm ntawm high-titanium-steel los ntawm kev tshawb fawb thiab kev tsim qauv uas ua ke nrog cov kev tshawb fawb theoretical hauv kev sim, kev npaj ua lag luam, thiab daim ntawv thov kev lag luam. Nws tau tsim "converter-LF-RH-slab nruam casting-rolling" txheej txheem kev npaj rau titanium-muaj hnav-resistant steel, thiab muaj tswv yim tsim ib lub koom haum tus kheej thiab nag lossis daus tswj tswvyim rau TiC particle-txhim kho titanium alloyed hnav-resistant hlau.
Tam sim no, Panzhihua Hlau thiab Hlau tau ua tiav tiav daim ntawv thov ntawm titanium alloy hnav-resistant steel casting tshuab ntawm "converter-slab nruam casting-kub dov" nyob rau hauv Suav teb, sau qhov sib txawv ntawm domestic "converter-slab nruam casting" ntau lawm. titanium-steel technology. Tib lub sijhawm, nyob rau hauv cov txheej txheem ntawm kev hnav-resistant steel, cov txheej txheem "micro-alloying + heat treatment" cov txheej txheem tsis tau txais, tab sis TiC hais yog siv los txhim kho kev hnav tsis kam thiab txhim kho toughness.
Piv nrog rau cov txheej txheem "hluav taws xob rauv-pwm casting", titanium alloyed hnav-resistant steel tsim los ntawm Panzhihua Hlau thiab hlau siv cov txheej txheem "converter-nruam casting" muaj qhov zoo ntawm kev ua haujlwm siab, siab yield tus nqi, tsis tshua muaj nqi thiab ntau yam ntawm cov khoom siv. Piv nrog rau cov tsoos hnav-resistant steel, titanium alloyed hnav-resistant steel tsis xav tau kev kho cua sov, muaj cov txheej txheem tsim khoom yooj yim, muaj ob qho tib si hnav tsis kam thiab toughness, thiab yog siv dav hauv cov thoob khib nyiab tsheb, sib tov tank steel, thee tshuab tsheb thauj mus los steel. , thiab lwm yam, thiab muaj kev thov dav dav.
Cov thev naus laus zis tau kawm hauv qhov project no kuj tseem tuaj yeem siv los tsim ntau hom high-titanium steel, muab cov txheej txheem tseem ceeb thiab cov cuab yeej technology rau Panzhihua Hlau thiab Hlau txhawm rau txhim kho thiab txhim kho kev ua haujlwm siab, tsis tshua muaj nqi titanium-muaj siab. -cov khoom siv thev naus laus zis thiab paub txog tus nqi qis, kev ua haujlwm siab, kev npaj loj thiab daim ntawv thov, thiab muab cov kev pabcuam muaj zog rau kev txhawb nqa cov txiaj ntsig sib sib zog nqus txuas ntxiv thiab kev txhim kho kom ruaj khov ntawm Panxi vanadium-titanium kev lag luam saw, thiab txhim kho tag nrho. theem ntawm kuv lub teb chaws high-titanium-steel ntau lawm thiab tus kheej-sufficiency tus nqi ntawm high-end khoom.
