Dab tsi yog qhov txawv ntawm channel steel thiab kuv -steel?
Txawm hais tias kuv -section steel yog zoo tib yam los yog lub teeb, vim hais tias cov seem loj yog qhov siab thiab nqaim, lub sij hawm ntawm inertia ntawm ob lub ntsiab axes ntawm seem yog loj, yog li nws tsuas yog siv ncaj qha nyob rau hauv lub web dav hlau dabtsi yog khoov cov tswv cuab los yog nws yog tsim los ntawm lattice kev nyuaj siab cov tswv cuab. Cov tswv cuab axial compression los yog cov tswv cuab uas yog perpendicular rau lub vev xaib dav hlau thiab khoov yuav tsum tsis txhob siv, uas ua rau nws muaj kev txwv loj hauv daim ntawv thov ntau yam.
Channel steel yog carbon structural steel siv nyob rau hauv kev tsim kho thiab machinery, yog ib tug complex seem ntawm seem steel, nws seem puab yog zawj -puab. Channel steel yog tsuas yog siv nyob rau hauv lub tsev qauv, ntaub thaiv phab ntsa engineering, mechanical khoom thiab tsheb manufacturing. Hauv kev siv, nws yuav tsum muaj kev sib txuas zoo dua, riveting thiab cov khoom siv kho tshuab dav dav.
Cov khoom siv raw khoom siv rau kev tsim cov channel steel yog carbon bonded steel lossis qis alloy steel billet nrog cov ntsiab lus tsis tshaj 0.25%. Cov hlau channel tiav yog xa los ntawm kev ua haujlwm kub, normalizing lossis kub dov.
Qhov txawv yog qhov zoo ntawm cov channel steel thiab qhov tso cai sib txawv ntawm cov duab geometric tau teev nyob rau hauv tus qauv. Feem ntau, qhov saum npoo yuav tsum tsis muaj qhov tsis zoo, thiab yuav tsum tsis muaj qhov torsion tseem ceeb, thiab tus nqi tso cai ntawm yoj khoov (sickle khoov) ntawm cov channel steel thiab qhov cuam tshuam tsis zoo ntawm cov duab ntawm cov channel steel ntawm txhua qhov tshwj xeeb (h, b, d, t, thiab lwm yam) thiab tus nqi kam rau ua. Lub ntsiab manifestations ntawm qhov tsis raug geometric duab ntawm channel steel yog: Lub kaum sab xis, ceg nthuav dav thiab ob txhais ceg sib luag. Ordinary I-steel, light I-steel, vim hais tias cov seem loj yog qhov siab thiab nqaim, yog li lub sijhawm ntawm inertia ntawm ob lub tes tsho tseem ceeb ntawm ntu yog loj, uas ua rau nws nyob rau hauv daim ntawv thov ntau yam muaj kev txwv loj. Kev siv I-beams yuav tsum raug xaiv raws li qhov xav tau ntawm cov duab kos duab.
