Isakhiwo sesakhelo se-arched yeyadi yesamente inobude obupheleleyo beemitha ezingama-40, ubude bubonke buziimitha ezingama-88 kunye nobude obuziimitha ezingama-700.
1. Umbhobho wensimbi wamkela i-Q235B, ipayipi yensimbi edibeneyo (GB / T 3092) okanye ipayipi yensimbi engenamthungo (GB / T 8162) ingasetyenziswa.
2. Ibhola yentsimbi yenziwe nge-Nombolo ye-45 ye-forgings yensimbi edibana ne "Technical Conditions for High-Quality Carbon Structural Steel" GB 699, kwaye amandla okuvelisa yi-360N / mm2.
3. Iibholiti eziphezulu zesakhelo segridi zenziwe nge-40Cr zicinywe kwaye zifudumeze kwaye ziphathwe ngokushushu ngokwe "Technical Conditions of High-Quality Carbon Structural Steel" GB/T 16939.
4. Ipleyiti yokutywina yentloko ye-cone yenziwe ngentsimbi ye-Q235B, kwaye intloko ye-cone yenziwe nge-forgings.I-diameter yangaphakathi ye-casingI-M33 yamkela i-Q355B.
5. I-nut engenamsonto yenziwe nge-Q235B yentsimbi ye-forgings.Xa ububanzi beebholiti eziphezulu eziphezulu> M30, sebenzisa i-45-gauge forgings steel forgings.
6. Izikhonkwane zokuqinisa zenziwe nge-40Cr eziye zacinywa kwaye zavutha.
7. Insimbi ye-Q235B isetyenziselwa ukuxhasa, ipleyiti edibeneyo, inkxaso kunye neengxenye zayo zokudibanisa.
8. I-purlins zenziwe ngentsimbi epholileyo epholileyo eyenziwe ngentsimbi ye-Q235B.
9. Iibholithi eziqhelekileyo zenziwe ngeebhotshi ze-C-grade ezenziwe nge-Q235 yensimbi ehlangabezana neemfuno zomgangatho welizwe langoku, kwaye ibakala lokusebenza ngu-4.8.
10. Amabakala ensimbi akhankanywe ngasentla kufuneka abe nezatifikethi zomgangatho wezinto eziphathekayo kunye neengxelo zokuhlola kwakhona, ngokuhambelana neemfuno zemigangatho kazwelonke yangoku.
11. I-electrodes kunye neengcingo ezisetyenziselwa i-welding kufuneka zihlangabezane neemfuno zemigangatho yesizwe yangoku.Ukuwelda phakathi kweentsimbi ze-Q235B kwamkela i-E43 series electrode.
