Nta
- Precision & sib npaug
Advanced txias-kos duab thiab kub- dov technologies kom zoo ib yam sab- ntev raug nrog nruj tolerances tsawg tshaj li los yog sib npaug rau ± 0.1 hli, nrog rau ib tug du nto tiav, xa ruaj khov thiab zoo ib yam nyob rau hauv ntau lawm batches.
- Ntev -Lub Sij Hawm Durability
High- cov ntaub ntawv raw khoom zoo thiab kev tswj xyuas nruj kom ntev lub neej kev pabcuam ntawm peb cov square steel tuav, txo cov nqi hloov pauv rau cov neeg siv khoom hauv qhov chaw hnyav (xws li cov av noo siab, hnav hnyav).
- Zoo Machining thiab Vuam Performance
Square bar hlau tuaj yeem ua tiav tau yooj yim los ntawm kev siv tshuab, drilling, khoov, thiab vuam, tso cai rau nws hloov mus rau ntau yam kev tsim khoom thiab kev tsim kho.
Khoom siv thiab tshuaj muaj pes tsawg leeg
Plain carbon hlau:Q235, Q345 (feem ntau siv, tus nqi qis, zoo toughness).
Hlau alloy:45 #, 40Cr, 20CrMnTi (siv rau siab -lub zog txhua yam).
Stainless hlau:304, 316L (corrosion-resistant, siv nyob rau hauv tshuaj thiab khoom noj khoom haus khoom).
Main Components:Hlau (Fe) yog cov khoom siv hauv paus, nrog cov pa roj carbon (C) cov ntsiab lus feem ntau yog li ntawm 0.02% mus rau 2.11%, thiab muaj me me ntawm silicon (Si), manganese (Mn), phosphorus (P), thiab sulfur (S) thiab lwm yam.
Sab ntev li ntawm 5mm mus rau 200mm (customizable rau tshwj xeeb xav tau kev pab), thiab standard lengths yog 6m, 9m, los yog 12m. Kev kho deg muaj xws li kub- dov (ntxhiab saum npoo rau hnyav- lub luag haujlwm scenarios), txias- kos (nqus nto rau qhov tseeb), thiab galvanized (txhim kho corrosion rau sab nraum zoov siv)
Kev tsim khoom
Kub Rolling (Kub Rolled): Lub steel billet yog rhuab thiab ces dov los ntawm ib lub tshuab dov. Qhov saum npoo yog ntxhib, qhov tseeb qhov loj yog nruab nrab, tab sis lub toughness yog qhov zoo, thiab tus nqi qis.
Cold Drawing (Cold Drawn): Kub dov square steel yog txuas ntxiv los ntawm lub tshuab kos duab txias. Qhov saum npoo yog du, qhov tseeb qhov loj yog siab, hardness thiab lub zog nce, tab sis cov plasticity me ntsis txo.
Cold Bending (Cold Bending): Txias dabtsi yog khoov yog ua los ntawm steel strips lossis daim hlau (feem ntau yog rau hollow lossis nyias-walled square steel).
