Iindaba - "I-all-rounder" kwiPlate yeNtsimbi yeKhabhoni

Ipleyiti yentsimbi yekhabhoni yenye yezona ntlobo ziphambili zezinto zentsimbi. Isekelwe kwisinyithi, enomxholo wekhabhoni ophakathi kwe-0.0218%-2.11% (umgangatho wemizi-mveliso), kwaye ayinazo okanye ayinazo izinto ezincinci zokuxutywa. Ngokwemxholo wekhabhoni, inokwahlulwahlulwa ibe:
Intsimbi yekhabhoni ephantsi(C≤0.25%): ukuqina okuhle, kulula ukukucubungula, i-Q235 ikweli candelo;
Intsimbi yekhabhoni ephakathi(0.25%
Intsimbi yekhabhoni ephezulu(C>0.6%): ubulukhuni obuphezulu kakhulu kunye nokuqhekeka okuphezulu.

Intsimbi yekhabhoni ye-Q235: inkcazo kunye neeparamitha eziphambili (umgangatho we-GB/T 700-2006)

Ukwakhiwa	C	Si	Mn	P	S
Umxholo	≤0.22%	≤0.35%	≤1.4%	≤0.045%	≤0.045%

Iimpawu zoomatshini:
Amandla okuvelisa: ≥235MPa (ubukhulu ≤16mm)
Amandla okutsalwa: 375-500MPa
Ubude: ≥26% (ubukhulu ≤16mm)

Izinto kunye nokusebenza

Izixhobo:Izinto eziqhelekileyo ziqukaGR.B, X42, X46, X52, X56, X60, X65, X70, njl. njl.

Iimpawu zokusebenza
Amandla aphezulu: Iyakwazi ukumelana noxinzelelo oluphezulu oluveliswa zizinto ezifana neoyile kunye negesi yendalo ngexesha lokuthuthwa.
Ukuqina Okuphezulu: Akulula ukuphuka xa kuchaphazeleka yimpembelelo yangaphandle okanye utshintsho lwejoloji, okuqinisekisa ukusebenza ngokukhuselekileyo kombhobho.
Ukumelana kakuhle nokugqwala: Ngokweendawo ezahlukeneyo zokusetyenziswa kunye neendlela zokusasaza, ukukhetha izixhobo ezifanelekileyo kunye neendlela zonyango lomphezulu kunokumelana ngempumelelo nokugqwala kwaye kwandise ubomi benkonzo yombhobho.

Iimpawu "zomloli onamacangca" we-Q235

Ukusebenza kakuhle kokucubungula
Ukuxinana: Akukho mfuneko yokufudumeza kwangaphambili, ifanelekile kwi-arc welding, i-gas welding kunye nezinye iinkqubo (ezifana nokuthungela isakhiwo sentsimbi yokwakha);
Ukwakheka Kobandayo: Ingagotywa kwaye igximfizwe ngokulula (umzekelo: igobolondo lebhokisi yokusasazwa, umbhobho wokungenisa umoya);
Ukungakwazi ukusebenza: Ukusebenza okuzinzileyo phantsi kokusika ngesantya esiphantsi (ukucubungula iindawo zomatshini).
Ibhalansi epheleleyo yoomatshini

Amandla vs UkuqinaAmandla okukhupha i-235MPa athathela ingqalelo zombini ukumelana nomthwalo kunye nokumelana nempembelelo (xa kuthelekiswa ne-195MPa ye-Q195);
Uhlengahlengiso loNyango lomphezulu: Kulula ukuyigalela nge-galvanize kwaye uyitshize ngepeyinti (ezifana nee-guardrails, ii-keel zentsimbi ekhaphukhaphu).
Ukusebenza kakuhle kwezoqoqosho okugqwesileyo
Ixabiso liphantsi nge-15%-20% kunelentsimbi enamandla aphantsi (njenge-Q345), efanelekileyo ukusetyenziswa ngobukhulu.
Inqanaba eliphezulu lokuMisa
Ubukhulu obuqhelekileyo: 3-50mm (isitokhwe esaneleyo, ukunciphisa umjikelo wokwenza ngokwezifiso);
Imigangatho yokusetyenziswa: GB/T 700 (yasekhaya), ASTM A36 (elingana neyamazwe ngamazwe).

Thenga kwaye usebenzise "Isikhokelo Sokuphepha"

Ukuchongwa koMgangatho:
Inkangeleko: akukho mifantu, amanxeba, imigobo (umgangatho we-GB/T 709 plate shape);
Iwaranti: Jonga ukwakheka, iimpawu zoomatshini kunye nengxelo yokufunyanwa kweziphene (ukufunyanwa kweziphene ze-UT kuyafuneka kwiindawo ezibalulekileyo zesakhiwo).
Icebo lokulwa nokugqwala:
Ngaphakathi endlini: ipeyinti yokulwa nomhlwa (njengepeyinti ebomvu yentsimbi) + i-topcoat;
Ngaphandle: i-hot-dip galvanizing (i-coating ≥85μm) okanye i-spray fluorocarbon coating.
Inqaku lokuWelda:
Ukukhetha intonga yokuwelda: Uthotho lwe-E43 (olufana ne-J422);
Ipleyiti ebhityileyo(≤6mm): akukho mfuneko yokufudumeza kwangaphambili, ipleyiti etyebileyo (>20mm): fudumeza kwangaphambili i-100-150℃ ukuthintela ukuqhekeka.
