Imibhobho yentsimbi engenamthungo idlala indima ebalulekileyo kwizicelo zoshishino, kunyeEN 10210kunye ne-EN 10216 yimigaqo emibini eqhelekileyo kwimigangatho yaseYurophu, ejolise kwimibhobho yentsimbi engenamthungo kulwakhiwo kunye nokusetyenziswa koxinzelelo ngokulandelelanayo.

EN 10210 esemgangathweni
Izinto kunye nokwakheka:
IEN 10210umgangatho usebenza kwimibhobho yentsimbi engenamthungo eyenziwe eshushu kwizakhiwo. Izinto eziqhelekileyo ziquka i-S235JRH, S275J0H,S355J2H, njl. Izinto eziphambili ze-alloy ezi zinto ziquka i-carbon (C), i-manganese (Mn), i-silicon (Si), njl njl. Ngokomzekelo, umxholo wekhabhoni we-S355J2H awudluli i-0.22%, kwaye umxholo we-manganese malunga ne-1.6%.

Ukuhlolwa kunye neemveliso ezigqityiweyo:
EN 10210imibhobho yentsimbi kufuneka ingene kuvavanyo olungqongqo lwepropathi yoomatshini, kubandakanywa ukomelela, ukomelela kwesivuno kunye novavanyo lobude. Ukongeza, iimvavanyo zokuqina kwempembelelo ziyafuneka ukuze kuqinisekiswe ukusebenza kwindawo yobushushu obuphantsi. Imveliso egqityiweyo kufuneka ihlangabezane nokunyamezelwa kwe-dimensional kunye neemfuno zomgangatho ophezulu ezichazwe kumgangatho, kwaye umphezulu udla ngokuba ngumhlwa.

EN 10216 esemgangathweni
Izinto kunye nokwakheka:
Umgangatho we-EN 10216 usebenza kwimibhobho yentsimbi engenamthungo yokusetyenziswa koxinzelelo. Izinto eziqhelekileyo zibandakanya i-P235GH, i-P265GH, i-16Mo3, njl. Ezi zixhobo ziqulethe izinto ezahlukeneyo ze-alloying. Ngokomzekelo, i-P235GH inomxholo wekhabhoni ongekho ngaphezu kwe-0.16% kwaye iqulethe i-manganese kunye ne-silicon; I-16Mo3 iqulethe i-molybdenum (Mo) kunye ne-manganese, kwaye inokumelana nokushisa okuphezulu.

Ukuhlolwa kunye neemveliso ezigqityiweyo:
I-EN 10216 imibhobho yentsimbi kufuneka iphumelele uluhlu lweenkqubo zokuhlola ezingqongqo, kubandakanywa uhlalutyo lwemichiza, uvavanyo lwepropathi ngoomatshini kunye novavanyo olungonakalisi (njengovavanyo lwe-ultrasonic kunye novavanyo lwe-X-ray). Umbhobho wensimbi ogqityiweyo kufuneka uhlangabezane neemfuno zokuchaneka kobukhulu kunye nokunyamezela kobunzima bodonga, kwaye ngokuqhelekileyo kufuna uvavanyo lwe-hydrostatic ukuqinisekisa ukuthembeka kwayo kwiindawo eziphakamileyo zoxinzelelo.

Isishwankathelo
IEN 10210kunye nemigangatho ye-EN 10216 yemibhobho yentsimbi engenamthungo yeyolwakhiwo kunye noxinzelelo lwemibhobho yentsimbi ngokulandelelanayo, egubungela imathiriyeli eyahlukeneyo kunye neemfuno zokwakheka. Ngokuhlola ngokungqongqo kunye neenkqubo zokuvavanya, iimpawu zomatshini kunye nokuthembeka kweepayipi zetsimbi ziqinisekiswa. Le migangatho ibonelela ngesiseko esithembekileyo sokukhethwa kwemibhobho yensimbi kwizicelo ezahlukeneyo zoshishino, ukuqinisekisa ukhuseleko kunye nokuzinza kweprojekthi.
