Kub dov seamless steel yeeb nkab, yuav tsum tau muaj tseeb, yog ib qho tseem ceeb ntau lawm txheej txheem rau seamless yeeb nkab.Nws qhov zoo tuaj yeem rhuav tshem cov qauv ntawm cov hlau ingot, ua kom cov nplej ntawm cov hlau, thiab tshem tawm qhov tsis xws ntawm microstructure, thiaj li ua kom cov qauv steel compact thiab txhim kho nws cov khoom siv kho tshuab.Qhov kev txhim kho no feem ntau yog tshwm sim hauv cov kev taw qhia dov, kom cov hlau tsis muaj isotropic rau qee yam;npuas, tawg thiab porosity tsim thaum lub sij hawm pouring kuj yuav welded nyob rau hauv kub thiab siab.
