Z-kev taw qhia steel
Z-kev taw qhia kev ua tau zoo kuaj steel kuj yog Z-kev taw qhia steel, laminar tsim kua muag resistant steel. Cov hlau phaj thiab cov seem hlau yog dov thiab tsim, thiab cov hlau siv nyob rau hauv ntau-high-rise steel qauv yog feem ntau kub dov, uas tuaj yeem rhuav tshem cov qauv casting ntawm lub ingot thiab kho cov nplej ntawm cov hlau.
Cov npuas thiab cov kab nrib pleb tsim thaum lub ingot yog nchuav tuaj yeem welded nyob rau hauv qhov kub thiab txias, kom cov khoom siv ntawm cov hlau tuaj yeem txhim kho. Qhov kev txhim kho no feem ntau yog cuam tshuam rau hauv cov kev taw qhia dov, vim tias cov khoom tsis yog xim hlau suav nrog hauv cov hlau yog nias rau hauv cov ntawv tom qab dov, thiab tseem nyob hauv cov phaj steel, kom cov phaj steel yog stratified. Qhov no non-metallic interlayer tshwm sim ua phem rau kev ua tau zoo ntawm cov hlau raws li cov kev taw qhia tuab, yog li cov khoom siv ntawm cov hlau phaj hauv peb cov lus qhia txawv; Kev ua tau zoo raws li qhov kev taw qhia dov yog qhov zoo, qhov kev ua tau zoo perpendicular mus rau qhov kev taw qhia dov yog me ntsis tsis zoo, thiab kev ua tau zoo raws li cov thickness kev taw qhia yog thib ob. Raws li ib txwm muaj, cov hlau phaj tuab yog ib qho yooj yim los tsim cov kua muag laminar, feem ntau vim tias cov hlau phaj tuab dua, qhov tsis zoo ntawm cov hlau tsis sib xws, qhov tuab ntawm cov vuam, qhov ntau dua qhov vuam kev nyuaj siab thiab deformation. Txhawm rau daws qhov teeb meem no, Z-kev taw qhia kev ntsuas kev ua tau zoo tuaj yeem siv tau. Z kev ua tau zoo xeem steel yog nyob rau hauv lub hauv paus ntawm ib tug tej yam theem ntawm cov qauv steel, tom qab tshwj xeeb smelting, kev kho mob ntawm hlau, nws cov ntsiab lus sulfur yog tsawg tshaj li ib feem tsib ntawm cov hlau dav dav, seem shrinkage tus nqi ntawm ntau tshaj 15 feem pua. Cov khoom siv hluav taws xob ntawm cov hlau phaj raws li kev taw qhia baidu yog hu ua z-direction zog.
