AH36 / EH36 steel phaj Z-kev taw qhia kev ua haujlwm
1. Z kev taw qhia yog dab tsi?
Z-kev taw qhia steel: tseem hu ua "lamellar tearing resistant steel", uas yog feem ntau hu ua Z-kev taw qhia kev ua tau zoo. Nyob rau hauv cov qauv hlau txuas nrog vuam, thaum lub thickness ntawm cov hlau phaj tsis tsawg tshaj li 40 hli thiab nws bears tensile quab yuam raws thickness kev taw qhia ntawm lub phaj, thiaj li tsis txhob lamellar tearing thaum lub sij hawm vuam, nws yog tsim nyog los siv cov hlau uas resists. lamellar tearing (feem ntau hu ua "Z"). "Rau Steel"). Cov phaj tuab muaj teeb meem lamellar tearing, yog li Z-kev taw qhia kev ntsuas yuav tsum tau ua.
2. Z-kev taw qhia kev ua tau zoo thiab nws qhov cuam tshuam rau cov phaj hlau nws tus kheej
Cov phaj hlau thiab steel seem yog dov thiab tsim. Feem ntau, cov hlau siv nyob rau hauv ntau qhov siab-siab steel qauv yog kub dov. Kub dov tuaj yeem rhuav tshem cov qauv casting ntawm cov hlau ingot thiab kho cov nplej ntawm cov hlau. Cov npuas thiab cov kab nrib pleb tsim thaum lub sij hawm nchuav cov hlau ingots tuaj yeem welded nyob rau hauv qhov kub thiab txias, yog li txhim kho cov khoom siv ntawm cov hlau. Txawm li cas los xij, qhov kev txhim kho no feem ntau tshwm sim hauv kev taw qhia dov, vim tias cov khoom tsis yog xim hlau (tsuas yog sulfides, oxides, silicates, thiab lwm yam) hauv cov hlau yog nias rau hauv cov ntawv nyias tom qab dov thiab tseem nyob hauv cov hlau phaj (feem ntau sib npaug rau qhov saum npoo ntawm cov hlau phaj), ua rau cov phaj hlau tshwm delaminated (interlayered). Qhov no non-metallic interlayer phenomenon. Deteriorating lub tensile zog ntawm cov hlau raws thickness kev taw qhia. Yog li ntawd, cov khoom siv ntawm cov hlau phaj sib txawv nyob rau hauv peb cov lus qhia: qhov zoo tshaj plaws raws li cov kev taw qhia dov; qhov kev ua tau zoo perpendicular rau dov kev taw qhia yog me ntsis zuj zus; thiab kev ua tau zoo raws li cov thickness kev taw qhia yog thib ob. Feem ntau, cov phaj tuab tuab yog feem ntau ua rau lamellar tearing, vim tias cov hlau phaj tuab dua, ntau qhov tsis xws li cov hlau tsis sib xws, thiab qhov tuab ntawm cov vuam, qhov ntau dua qhov vuam kev nyuaj siab thiab deformation. Txhawm rau daws qhov teeb meem no, nws yog qhov zoo tshaj los siv Z-kev taw qhia steel. Hom steel phaj no yog ib qho tshwj xeeb smelted thiab kho steel raws li cov qib ntawm cov qauv hlau (hu ua niam txiv steel). Nws cov ntsiab lus sulfur yog tsawg dua 1/5 ntawm cov hlau zoo tib yam, thiab nws qhov kev sib tshuam ntawm qhov shrinkage yog ntau tshaj 15%. . Cov khoom siv kho tshuab (feem ntau yog cov khoom siv ductility) ntawm cov phaj hlau raws li cov kev taw qhia tuab yog hu ua Z-kev taw qhia cov khoom. Z-kev taw qhia cov khoom ntawm cov hlau phaj tuaj yeem tau txais los ntawm kev ntsuas tensile ntawm cov qauv, thiab feem ntau ntsuas los ntawm qhov shrinkage ntawm cheeb tsam. Z-kev taw qhia steel daim hlau tsim nyob rau hauv kuv lub teb chaws yog cim los ntawm kev ntxiv Z-kev taw qhia steel phaj qib qhab nia Z25, Z25, thiab Z25 tom qab tus niam txiv steel tooj. Tus lej tom qab Z yog qhov taw qhia ntawm qhov sib txawv ntawm qhov shrinkage tus nqi (%).
