Litaba - The "all-rounder" in Carbon Steel Plate

Letlapa la tšepe ea carbon ke e 'ngoe ea likarolo tsa mantlha tsa thepa ea tšepe. E thehiloe holim'a tšepe, e nang le carbon content pakeng tsa 0.0218% -2.11% (tekanyetso ea indasteri), 'me e na le che kapa e nyenyane ea likarolo tsa motsoako. Ho ea ka carbon content, e ka aroloa ka:
Tšepe e tlaase ea carbon(C≤0.25%): boima bo botle, bo bonolo ho sebetsa, Q235 ke ea sehlopha sena;
Tšepe ea khabone e mahareng(0.25%
Tšepe e phahameng ea carbon(C> 0.6%): boima bo phahameng haholo le bofokoli bo phahameng.

Matla a Phahameng: E khona ho mamella khatello e phahameng e hlahisoang ke maro a kang oli le khase ea tlhaho nakong ea lipalangoang.
Matla a Phahameng: Ha ho bonolo ho robeha ha ho na le tšusumetso e ka ntle kapa liphetoho tsa jeoloji, ho netefatsa ts'ebetso e bolokehileng ea lipeipi.
Ho hanyetsa Corrosion e ntle: Ho latela maemo a fapaneng a ts'ebeliso le mecha ea litaba, ho khetha lisebelisoa tse nepahetseng le mekhoa ea kalafo ea holim'a metsi ho ka hanela kutu le ho lelefatsa bophelo ba tšebeletso ea liphaephe.

Ts'ebetso e Ntle ea Ts'ebetso
Weldability: Ha ho na preheating e hlokahalang, e loketseng bakeng sa welding ea arc, welding ea khase le mekhoa e meng (e kang ho haha mohaho oa tšepe oa tšepe);
Cold Formability: E ka kobeha habonolo le ho hatisoa (mohlala: khetla ea lebokose la kabo, duct ea ventilation);
Boikemisetso: Ts'ebetso e tsitsitseng tlas'a ho itšeha ka lebelo le tlaase (ho sebetsa likarolo tsa mochine).
Comprehensive Mechanical Balance

Matla vs Matla: Matla a tlhahiso ea 235MPa a nahanela bobeli ba ho jara le ho hanyetsa tšusumetso (ha ho bapisoa le Q195's 195MPa);
Ho Fetola Phekolo ea Bokahohle: Ho bonolo ho galvanize le ho fafatsa pente (joalo ka litšepe, litšepe tse bobebe).
Tšebeliso e Ntle ea Moruo
Theko e ka bang 15% -20% e tlase ho feta ea tšepe e tlaase ea alloy e matla (e kang Q345), e loketseng bakeng sa kopo e kholo.
Boemo bo Phahameng ba Boemo
Botenya bo tloaelehileng: 3-50mm (setoko se lekaneng, ho fokotsa potoloho ea tloaelo);
Maemo a ts'ebetsong: GB/T 700 (ea malapeng), ASTM A36 (e lekanang le machaba).

Reka le ho Sebelisa "Avoidance Guide"

Boitsebiso ba Boleng:
Ponahalo: ha ho mapetsong, maqeba, mameno (GB / T 709 plate shape standard standard);
Tiisetso: Lekola sebopeho, thepa ea mochini le tlaleho ea ho lemoha liphoso (ho hlokahala ho fumana liphoso tsa UT bakeng sa likarolo tsa bohlokoa tsa sebopeho).
Leano la anti-corrosion:
Ka hare: pente e khahlanong le mafome (e kang pente e khubelu ea loto) + topcoat;
Kantle: hot-dip galvanizing (ho roala ≥85μm) kapa ho fafatsa seaparo sa fluorocarbon.
Welding Note:
Khetho ea molamu oa welding: Letoto la E43 (joalo ka J422);
Letlapa le lesesaane(≤6mm): ha ho na preheating e hlokahalang, poleiti e teteaneng (> 20mm): preheat 100-150 ℃ ho thibela mapetsong.
