Kub-dov yog ua raws li cov slab (feem ntau yog billet) raws li raw khoom, rhuab los ntawm ib tug roughing zeb thiab xov zeb pab pawg neeg ua los ntawm hlau.Los ntawm kev ua tiav qhov kawg ntawm qhov kub sawb zeb los ntawm laminar txias rau qhov kub thiab txias, lub tshuab coiling dov steel strip coils, steel yob txias los ntawm kev sib txawv ntawm cov kab ua tiav thiab ua cov hlau, tiaj tus ntim thiab slitting steel khoom.

Kev kos duab txias txhais tau hais tias nyob rau hauv chav tsev kub, tom qab kos duab txias, khoov, kos duab thiab lwm yam txias phaj los yog sawb rau hauv kev ua ntawm ntau hom hlau.

Kub dov thiabtxias dov qhov txawv:

1, Kub dov thiab txias drawn steel los yog steel phaj txheej txheem yog tib yam, lawv muaj kev cuam tshuam zoo rau lub microstructure thiab mechanical zog ntawm steel, dov hlau, kub-kuav los tiag raws li, txias-dov hlau tsuas yog siv rau zus tau tej cov steel. me me thiab daim ntawv.

2, Cold-formed steel cross-section zoo nkaus li tso cai rau hauv zos buckling, uas tuaj yeem siv tag nrho cov pas nrig bearing peev tom qab buckling;thaum kub-dov hlau tsis pub hla ntu ntawm lub zos buckling tshwm sim.

3, Rau ntau yam yog vim li cas kub-kuav los tiag steel thiab txias-kuav los tiag steel residual kev nyuaj siab, yog li kev faib ntawm tus ntoo khaub lig seem kuj txawv heev.Cold-formed steel residual stress distribution on the cross-section is curved, and hot rolled steel or welded steel section of the residual stress distribution is a film type.

4, Kev ywj pheej ntawm kub-kuav los tiag steel txias-kuav los tiag steel siab torsional stiffness piv, yog li torsional kev ua tau zoo dua li kub-dov hlau txias-kuav los tiag steel.

5, Kub dov txheej txheem: raj - cua sov - kub punch - dov - txias txaj, txias txheej txheem: pib - xyaum qhov - pickling - phosphate - kos duab - annealing.
