1. Dab tsi yog qhov zoo tshaj plaws ntawm cov yeeb nkab kub dov, thiab vim li cas?
Teb:Kub dov yeeb nkab feem ntau muaj ntxhib, xiav - grey, scaled nto. Qhov ntsuas no yog txheej oxide (feem ntau yog hlau oxide) uas tsim thaum cov hlau kub raug cua thaum lub sij hawm dov thiab txias. Nws tsis tshua muaj kev zoo nkauj tab sis feem ntau siv tau rau ntau daim ntawv thov kev lag luam.
2. Cov txheej txheem kub dov ua li cas cuam tshuam rau cov txheej txheem ntawm cov hlau sab hauv?
Teb:Cov txheej txheem kub dov refines lub grain qauv ntawm cov hlau. Kev kub siab thiab kev siv tshuab ua haujlwm ua rau qhov ntxhib, xws li - nrum cov qauv, ua rau cov nplej zoo dua, zoo dua qub. Qhov no feem ntau txhim kho cov khoom siv kho tshuab, xws li toughness thiab lub zog.
3. Dab tsi yog qhov txawv ntawm Seamless thiab Welded Kub Rolled Yeeb Nkab?
Teb:
Seamless Kub Rolled Yeeb Nkabyog tsim los ntawm ib tug khoom billet tsis muaj weld seam. Nws feem ntau muaj zog thiab txhim khu kev qha rau siab - cov ntawv thov siab.
Welded Kub Rolled Yeeb Nkabyog tsim los ntawm dov lub phaj kub (skelp) rau hauv lub tog raj kheej thiab tom qab ntawd vuam cov seam (xws li, siv hluav taws xob tsis kam vuam). Nws yog kev lag luam ntau dua thiab muaj nyob rau hauv cov kab loj dua.
4. Dab tsi yog "normalizing" thiab vim li cas nws thiaj li feem ntau siv rau cov kav dej kub dov?
Teb:Normalizing yog txheej txheem kev kho cua sov uas cov yeeb nkab tau rhuab mus rau qhov kub thiab txias thiab tom qab ntawd cua - txias. Nws yog siv rau kub dov kav mus rau:
Txo cov kev ntxhov siab sab hauv los ntawm kev dov thiab txias.
Kho cov qauv nplej kom zoo dua cov khoom siv kho tshuab.
Txhim kho toughness thiab machinability.
5. Dab tsi yog qhov dav dav rau cov yeeb nkab kub dov?
Teb:Tolerances txawv raws li specification tab sis feem ntau npog:
Sab nraud txoj kab uas hla (±):Feem ntau ntawm 0.75% mus rau 1%.
Phab ntsa Thickness (±):Feem ntau nyob ib ncig ntawm 12.5%.
Ntev (±):Nws txawv tab sis muaj peev xwm raug teev rau random los yog pes tsawg lengths.
