Ntchito

1. Chitoliro chachitsulo chachitsulo chiyenera kugwirizana ndi Q235B chitsulo chotchulidwa mu "Carbon Structural Steel" GB700 ndi chitoliro chachitsulo chopangidwa ndi GB3092 kapena chitoliro cha 20 chopanda chitsulo chotchulidwa ndi GB3087.
2. Mpira wa bolt umapangidwa ndi No. 45 zitsulo zotchulidwa mu GB699, ndipo pamwamba payenera kukhala yosalala, popanda ming'alu, osawotcha kwambiri, komanso opanda pitting.
3. Mabotolo amphamvu kwambiri amapangidwa ndi zinthu zomwe zafotokozedwa mu GB/T16939-1997 za "Maboti amphamvu kwambiri opangira ma gridi achitsulo ndi zolumikizira mpira".Chomalizidwacho sichimalola kuzimitsa ming'alu yakuya kapena kutalika kulikonse mu gawo lililonse.Gawo la magwiridwe antchito a mabawuti amphamvu kwambiri liyenera kukwaniritsa zofunikira za "Maboti achitsulo apamwamba kwambiri a ma bawuti a gridi ndi zolumikizira mpira "GB/T16939-1997", kulimba kwapamtunda kuyenera kufikira HRC32 ~ 36, ulusi uyenera kukwaniritsa mulingo wa 6g mu "General Thread Tolerance and Fit" GB197, ndipo pamwamba ayenera kuda ndi utoto.
4. Zida za mbale yosindikizira ndi mutu wa cone ziyenera kugwirizana ndi chitsulo cha Q235 chotchulidwa mu GB700, ndipo zida za manja ndi manja ziyenera kugwirizana ndi chitsulo cha Q235 chomwe chili mu GB700 kapena chitsulo cha 16Mn chotchulidwa mu "Technical Conditions for Low Alloy Structural Steel" GB1591 kapena "High Quality Carbon Structure".Kwa No. 45 chitsulo chotchulidwa mu GB699, maonekedwe a mbale yosindikizira, mutu wa cone ndi manja sizikhala ndi ming'alu, kuwotcha kwambiri ndi sikelo.
5. Ndodo yowotcherera: E43XX mndandanda wasankhidwa;kugwirizana weld kalasi zofunika: matako kuwotcherera chitoliro chachikulu ndi zonse malowedwe kuwotcherera, ndi weld khalidwe kalasi ndi kalasi yoyamba.Magulu abwino a ma welds onse olowera ndi Class II;
6 Zida ziyenera kukhala ndi ziphaso zabwino ndi malipoti ovomerezeka, mipira yachitsulo iyenera kulembedwa ndi manambala a ntchito, zowotcherera zonse ziyenera kulembedwa ndi manambala a ntchito zowotcherera, ndipo ubwino wa zinthu zonse uyenera kugwirizana ndi <<> JGJ75.1~75.3-91
7. Chitsulo chomwe chimagwiritsidwa ntchito ponyamula katundu chiyenera kukhala ndi chiphaso cha mphamvu zowonongeka, kutalika, mphamvu zokolola ndi sulfure ndi phosphorous.
Chitsulo chomwe chimagwiritsidwa ntchito pazitsulo zomangika zonyamula katundu ndi zofunikira zosamangika zosamangika zimakhalanso ndi satifiketi yoyeserera yopindika yozizira.
