Indlela yokwahlula izinto zeplate yentsimbi yi-Q235 kunye ne-Q345?

Q235 ipleyiti yentsimbikwayeQ345 ipleyiti yentsimbiazibonakali ngokubanzi ngaphandle. Ukwahlukana kombala akunanto yakwenza nezinto zentsimbi, kodwa kubangelwa iindlela ezahlukeneyo zokupholisa emva kokuba intsimbi ikhutshwe. Ngokuqhelekileyo, ubuso bubomvu emva kokupholisa kwendalo. Ukuba indlela esetyenzisiweyo ipholisa ngokukhawuleza, umphezulu wokubunjwa kwe-dense oxide layer, iya kubonisa umnyama.
Uyilo lwamandla ngokubanzi kunye ne-Q345, kuba i-Q345 kune-Q235 amandla ensimbi, gcina intsimbi, ngaphezu kwe-235 igcina i-15% - 20%. Kuyilo lolawulo lozinzo ngeQ235 elungileyo. Umahluko wexabiso le-3% --- 8%.

Ngokuphathelele ukuchongwa, kukho iingxelo ezininzi:
A.
1, umzi-mveliso unokusetyenziselwa ukuvavanya iindlela ze-welding ukwahlula phakathi kwezi zinto zimbini. Umzekelo, kwiziqwenga ezibini ipleyiti yentsimbi kunye E43 intonga welding zaye welded intsimbi encinane ngeenxa zonke, uze usebenzise amandla ukucheba, ngokutsho ukutshatyalaliswa imeko ukwahlula phakathi kweentlobo ezimbini ipleyiti yentsimbi.
2, umzi-mveliso unokusebenzisa ivili lokusila ukwahlula phakathi kwezi zinto zimbini. Intsimbi ye-Q235 enevili lokugaya xa ugaya, iintlantsi ziyisuntswana elingqukuva, umbala omnyama. Kwaye iintlantsi ze-Q345 zine-bifurcated, umbala oqaqambileyo.
3, kukwakho ngokutsho kwentsimbi emibini yokucheba umphezulu umahluko wombala unokwahlula phakathi kweentlobo ezimbini zentsimbi. Ngokubanzi, Q345 shear umlomo umbala mhlophe
B.
I-1, ngokombala wepleyiti yensimbi inokwahlula phakathi kwe-Q235 kunye ne-Q345 impahla: umbala we-Q235 oluhlaza, i-Q345 enye ebomvu (oku kuphela kwintsimi yentsimbi, ixesha alinakuhlukaniswa)
I-2, uvavanyo lwezinto ezibonakalayo ezibonakalayo luhlalutyo lweekhemikhali, i-Q235 kunye ne-Q345 i-carbon content ayifani, ngelixa umxholo wekhemikhali awufani. (Le yindlela yobudenge)
I-3, ulwahlulo phakathi kwe-Q235 kunye ne-Q345 yezinto eziphathekayo, kunye ne-welding: iziqwenga ezimbini zezinto ezingabonakaliyo ze-steel butt, kunye nentonga ye-welding eqhelekileyo kwi-weld, ukuba kukho ukuqhekeka kwelinye icala lentsimbi yensimbi ibonakaliswe ukuba yi-Q345 impahla. (La ngamava asebenzayo)
