Iiprojekthi

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 sesithuba 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.

12. Umlinganiselo wexabiso elilinganisiweyo lamandla okuvelisa kwixabiso elilinganisiweyo lamandla obunzima bensimbi akufanele kube mkhulu kune-0.85.

13. Intsimbi kufuneka ibe namanyathelo okuvelisa acacileyo, kwaye i-elongation akufanele ibe ngaphantsi kwe-20%.

14. Intsimbi kufuneka ibe ne-weldability efanelekileyo kunye nokuqina kwempembelelo efanelekileyo.Xa intsimbi ye-Q235B, umgangatho wayo womgangatho kufuneka uhambelane ne "Carbon Structural Steel" (GB700-88), kwaye xa i-Q355B, umgangatho wayo womgangatho kufuneka uhambelane ne "Low Alloy High Strength Structural Steel" GB / T1491, zonke iintsimbi kufuneka Unesiqinisekiso sokuqina, ukomelela, ukomelela kwesivuno, uvavanyo lokugoba olubandayo kunye nekhabhoni, isulfure kunye nomxholo wephosphorus.Isakhiwo esidibeneyo siya kuba nesiqinisekiso esifanelekileyo somxholo wekhabhoni.
