Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Siyaziqhenya ngokwethula umkhiqizo wethu osezingeni eliphezulu,Ipayipi Lensimbi Ejikelezayo le-S235 J0, eklanyelwe ukuhlangabezana nezidingo ezikhulayo zezimboni ezahlukene. Njengomkhiqizi ohamba phambili kulo mkhakha, sisebenzisa ubuchwepheshe obuthuthukisiwe kanye nobuchwepheshe ukukhiqiza ikhwalithi ephezuluipayipi lomugqa ngokuqina nokusebenza okuhle kakhulu.

Amapayipi ethu ensimbi ajikelezayo enziwe ngama-strip steel coils ngokusebenzisa inqubo yokuwelda ye-arc engaphansi kwamanzi enama-double-wire double sides. Ngobuchwepheshe bokubumba be-extrusion yokushisa obuqhubekayo, siqinisekisa ukuthi ithubhu ngalinye likhiqizwa ngokunemba okuphezulu kanye nokuvumelana. Le nqubo yokukhiqiza ecophelelayo iqinisekisa ukuthi imikhiqizo yethu ihlangabezana nezindinganiso zekhwalithi ephezulu, okwenza ifaneleke kakhulu ezinhlotsheni ezahlukene zokusebenza.

Uma kuqhathaniswa namapayipi endabuko ahlanganisiwe,Ipayipi lensimbi elijikelezayo le-S235 J0 inezici ezilandelayo ezibalulekile:

A. Ngesikhathi senqubo yokwakha, ipuleti lensimbi liyashintshashintsha ngokulinganayo futhi linokucindezeleka okuncane okusele. Lokhu akugcini nje ngokwandisa impilo yepayipi, kodwa futhi kuqinisekisa ukuthi ubuso bepayipi bubushelelezi futhi abunamihuzuko noma amaphutha.

b. Inqubo yethu yokushisela i-arc engaphansi kwamanzi enamacala amabili ethuthukisiwe yenza kube lula ukushisela okunembile endaweni engcono kakhulu. Lokhu kunciphisa kakhulu ukwenzeka kwamaphutha afana nemiphetho engalingani kahle, ukuphambuka kokushisela, kanye nokushisela okungaphelele. Ngenxa yalokho, amapayipi ethu anekhwalithi yokushisela enhle kakhulu, kulula ukuwalawula futhi aqinisekisa ukusebenza okuhle kakhulu.

C. Ikhwalithi iyinto eza kuqala kithi. Ngakho-ke, senza ukuhlolwa kwekhwalithi okuphelele okungu-100% kuwo wonke amapayipi ensimbi esiwakhiqizayo. Lokhu kuhlolwa okuphelele kuqinisekisa ukuthi amapayipi ethu ahlangabezana nezindinganiso eziphakeme kakhulu embonini, okukunikeza ukuthula kwengqondo kuyo yonke inqubo yokukhiqiza nokusebenzisa.

Kwa-Cangzhou Spiral Steel Pipe Group Co., Ltd., siyaziqhenya kakhulu ngokukhiqizaIpayipi Lensimbi Ejikelezayo le-S235 J0. Sitholakala eDolobheni laseCangzhou, eSifundazweni saseHebei futhi besilokhu sikhonza imboni kusukela ngo-1993. Njengoba ihlanganisa indawo engamamitha-skwele angu-350,000 kanye nempahla iyonke engama-yuan ayizigidi ezingu-680, ibeke isisekelo esiqinile samakhono okukhiqiza amahle kakhulu. Ithimba lethu elizinikele labasebenzi abanamakhono abangu-680 lisebenza ngokuzikhandla ukuqinisekisa ukukhiqizwa okungenamthungo kanye nokulethwa ngesikhathi kwamapayipi ensimbi angamathani angu-400,000 ngonyaka.

a. Indlela yokususa i-oxidation ichazwa kanje: FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020% iyonke i-Al noma i-0,015% i-Al encibilikayo). b. Inani eliphezulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al okungu-0,020% kanye nesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto ezibophayo ze-N ezanele. Izinto ezibophayo ze-N kufanele ziqoshwe kuDokhumenti Yokuhlola.
