Iithegi zeMveliso

Siyazingca ngokwazisa imveliso yethu ekumgangatho ophezulu,Umbhobho wentsimbi ejikelezayo ye-S235 J0, eyenzelwe ukuhlangabezana neemfuno ezikhulayo zamashishini ahlukeneyo. Njengomvelisi okhokelayo kweli candelo, sisebenzisa ubuchwepheshe obuphambili kunye nobuchule ukwenza izinto ezikumgangatho ophezuluumbhobho womgca ngokuqina nokusebenza okugqwesileyo.

Iipayipi zethu zentsimbi ezijikelezayo zenziwe ngee-strip steel coils ngokusebenzisa inkqubo yokuwelda ye-arc engaphantsi kwamanzi enamacala amabini ezenzekelayo. Ngokusebenzisa ubuchwepheshe bokubumba obuqhubekayo bokukhupha ubushushu, siqinisekisa ukuba ityhubhu nganye iveliswa ngokuchanekileyo nangokungaguquguquki okuphezulu. Le nkqubo yokuvelisa ecokisekileyo iqinisekisa ukuba iimveliso zethu ziyahlangabezana nemigangatho ephezulu yomgangatho, nto leyo eyenza ukuba zilungele ukusetyenziswa ngeendlela ezahlukeneyo.

Xa kuthelekiswa nemibhobho yendabuko edibeneyo,Umbhobho wentsimbi ojikelezayo we-S235 J0 ineempawu ezibalulekileyo ezilandelayo:

A. Ngexesha lenkqubo yokwenza, ipleyiti yentsimbi iyaguquguquka ngokulinganayo kwaye ayinaxinzelelo luninzi olushiyekileyo. Oku akupheleli nje ekwandiseni ubomi bombhobho, kodwa kuqinisekisa ukuba umphezulu wombhobho uthambile kwaye awunamikrwelo okanye iziphene.

b. Inkqubo yethu yokuwelda ye-arc engaphantsi kwamanzi enamacala amabini ivumela ukuwelda ngokuchanekileyo kwindawo efanelekileyo. Oku kunciphisa kakhulu ukwenzeka kweziphene ezifana nemiphetho engalungelelananga, ukuphambuka kokuwelda, kunye nokuwelda okungaphelelanga. Ngenxa yoko, imibhobho yethu inomgangatho ogqwesileyo wokuwelda, kulula ukuyilawula kwaye iqinisekisa ukusebenza kakuhle.

C. Umgangatho yeyona nto iphambili kuthi. Ke ngoko, senza uhlolo olupheleleyo lomgangatho oluyi-100% kuyo yonke imibhobho yentsimbi esiyivelisayo. Olu hlolo lupheleleyo luqinisekisa ukuba imibhobho yethu ihlangabezana nemigangatho ephezulu yoshishino, ikunika uxolo lwengqondo kuyo yonke inkqubo yokuvelisa nokusetyenziswa.

Apha eCangzhou Spiral Steel Pipe Group Co., Ltd., siyazingca kakhulu ngokuvelisaUmbhobho wentsimbi ejikelezayo ye-S235 J0SikwiSixeko saseCangzhou, kwiPhondo laseHebei kwaye besikhonza eli shishini ukusukela ngo-1993. Sigubungela indawo yeemitha zesikwere ezingama-350,000 kunye neempahla zizonke ezingama-680 ezigidi zeeyuan, sibeke isiseko esiqinileyo sezakhono ezibalaseleyo zemveliso. Iqela lethu elizinikeleyo labasebenzi abanezakhono ezingama-680 lisebenza nzima ukuqinisekisa imveliso engenamthungo kunye nokuhanjiswa ngexesha elifanelekileyo kweetoni ezingama-400,000 zeepayipi zentsimbi ezijikelezayo ngonyaka.

a. Indlela yokususa ioksijini ichazwe ngolu hlobo lulandelayo: FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha initrogen ngobuninzi obaneleyo ukubopha initrogen ekhoyo (umz. ubuncinci be-0,020% iyonke ye-Al okanye i-0,015% ye-Al enyibilikayo). b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukwakheka kweekhemikhali kubonisa umxholo opheleleyo we-Al ongama-0,020% kunye nomlinganiselo ophantsi we-Al/N oyi-2:1, okanye ukuba kukho ezinye izinto ezaneleyo zokubopha i-N. Izinto zokubopha i-N mazirekhodwe kuXwebhu loHlolo.
