Ukwakheka Kwamakhemikhali
Ipuleti le-carbon steel le-Q235D, ipuleti lensimbi eliqinile lisetshenziswa kabanzi ekwakhiweni, kwezimoto, ekwakhiweni kwemikhumbi, kwemishini nakwezokusebenza nezinye izimboni eziningi, kodwa ipuleti lensimbi elinamandla aphezulu kufanele likhethwe kahle. Okokuqala, izinga liphezulu kakhulu, okusho ukuthi intengo izoba phezulu ngenxa yezindleko eziphezulu zokukhiqiza. Okwesibili, izinga eliphansi lisho ukuthi ukusebenza kokuphepha akukho sezingeni. Okwesithathu, ukucaciswa kwamapuleti ensimbi anamandla aphezulu kufanele kukhethwe ngokuhambisana ngokuqinile nemidwebo yokuklama. Okwesine, kunconywa ukuthenga imishini ekhethekile yokuhweba ukuhlola amapuleti ensimbi anamandla aphezulu.

Inokuqina okuhle. Ngokulawula ngokuqinile ukwakheka kwamakhemikhali, ukunciphisa okuqukethwe kwezinto eziyingozi ku-Q235D carbon steel plate, nokukhetha izimo zokwelashwa kokushisa okunengqondo, i-NM360 steel plate inokuqina okuhle. Ngakho-ke, izingxenye zesakhiwo ezinokwethenjelwa okuphezulu zingakhiwa ngokuya ngokwehluleka okuqinile kwezingxenye ezingagugi. I-Q235D carbon steel plate yamukela ubuchwepheshe obuthuthukisiwe kanye nemishini, kuhlanganiswe nokuphathwa kobuchwepheshe okuphakeme nokwesayensi, ukuze impahla kanye nokuma komkhiqizo kufane futhi kube kuhle.
I-S355J2 steel plate Q235D carbon steel rolling process iyinqubo yokugoqa elawulwayo. Enqubweni yokugoqa, izinga lokushisa le-ingot liyi-1000-1050 ° C; Isigaba sokuqala samukela inqubo yokugingqika yokwehlisa isivinini esikhulu esiphansi, izinga lokushisa eliphezulu ngu-950-1000 °C, isivinini sokugoqa singu-1.6-2.0m/s, izinga elilodwa lokunciphisa le-Q235D carbon steel plate I-15-20%, futhi izinga lokunciphisa elikhulayo lingama-40-45% ukuze kuqinisekiswe ukuguqulwa okugcwele kwe-ingot. Esigabeni sokuqala, izinga lokushisa eliqala ukugoqa lingu-910-930 °C, futhi izinga lokushisa lokuqeda liyi-≤ 870 °C.
