Muaj ob hom yeeb nkab hlau tsis sib xws: cov yeeb nkab kub dov thiab cov yeeb nkab txias dov (hu xov tooj).
Cov kav hlau kub dov seamless tau muab faib ua cov kav hlau dav dav, cov kav hlau boiler siab qis thiab nruab nrab, cov kav hlau boiler siab siab, cov kav hlau alloy, cov kav hlau tawg roj av, cov kav hlau geological thiab lwm cov kav hlau.
Ntxiv rau cov kav hlau dav dav, cov kav hlau boiler siab qis thiab nruab nrab, cov kav hlau boiler siab siab, cov kav hlau alloy, cov kav roj tawg, thiab lwm yam kav hlau, cov kav hlau txias-dov (hu) seamless kuj suav nrog cov kav hlau carbon nyias-walled, cov kav hlau alloy nyias-walled, cov kav hlau profiled, thiab lwm yam.
Lub raj xa dej kub-kub seamless feem ntau yog loj dua 32 hli, thiab phab ntsa tuab yog 2.5-75 hli. Lub raj xa dej txias-kub seamless muaj txoj kab uas hla mus txog 6 hli, thiab phab ntsa tuab tuaj yeem ncav cuag 0.25 hli. Lub raj xa dej nyias-phab muaj txoj kab uas hla mus txog 5 hli, thiab phab ntsa tuab tsawg dua 0.25 hli. Kev dov txias muaj qhov tseeb ntawm qhov ntev dua li kev dov kub.
Cov kav hlau tsis muaj qhov tsis sib xws rau kev siv dav dav: yog ua los ntawm cov hlau carbon zoo xws li 10, 20, 30, 35, 45, 16Mn, 5MnV thiab lwm yam hlau tsis muaj hlau lossis 40Cr, 30CrMnSi, 45Mn2, 40MnB thiab lwm yam hlau sib xyaw uas yog kub-dov lossis txias-dov.
10, 20 thiab lwm yam yeeb nkab hlau tsis muaj hlau feem ntau yog siv rau cov kav dej xa dej. Cov yeeb nkab tsis muaj hlau ua los ntawm cov hlau carbon nruab nrab xws li 45 thiab 40Cr yog siv los tsim cov khoom siv kho tshuab, xws li cov khoom siv ntxhov siab ntawm lub tsheb thiab tsheb laij teb. Feem ntau, cov yeeb nkab hlau tsis muaj hlau yog siv los xyuas kom muaj zog thiab kev sim tiaj tus. Cov yeeb nkab hlau kub dov raug xa mus rau hauv lub xeev kub dov lossis kho cua sov; cov yeeb nkab hlau txias dov raug xa mus rau hauv lub xeev kho cua sov.
