Kub Rolled Seamless Steel Tube
Kub Rolled Seamless Steel Tube, Kub dov yog txheeb ze rau txias dov, txias dov yog dov hauv qab qhov kub ntawm recrystallization, thiab kub dov yog dov saum toj no lub recrystallization kub.
Kub Rolled Seamless Steel Tube, Qhov Zoo
Nws tuaj yeem rhuav tshem cov qauv ntawm cov hlau ingot, ua kom cov qoob loo loj ntawm cov hlau, thiab tshem tawm qhov tsis xws ntawm microstructure, kom cov qauv steel yog compacted thiab cov khoom siv kho kom zoo.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 looseness tsim thaum lub sij hawm casting kuj yuav welded nyob rau hauv kub thiab siab.
Kev faib tawm
