Monga mchenga woponyera maziko ochokera ku China, RMC imatha kuponyera zitsulo ndikuponya mchenga. Chitsulo choponyera chimatha kugawidwa muchitsulo chosungunuka ndi kuponyera chitsulo cha kaboni molingana ndi kapangidwe kake ka mankhwala, komanso chimatha kugawidwa ngati chitsulo chosungunula, chitsulo chapadera, zomangamanga ndi kuponyera kandalama ndi kuponyera aloyi chitsulo malinga ndi mawonekedwe ake.
Ndi mankhwala
1. Ponyani chitsulo cha kaboni. Ponyani chitsulo ndi kaboni ngati chinthu chachikulu chophatikizira komanso zinthu zina zochepa. Osewera mpweya wazitsulo amatha kugawidwa muzitsulo zazitsulo zazing'ono, kupangira chitsulo chosakanikirana ndi mpweya. Mpweya wa kaboni wazitsulo wazitsulo wocheperako ndi wochepera 0.25%, zomwe zimapangidwa ndi mpweya wazitsulo zili pakati pa 0.25% ndi 0.60%, ndipo mpweya wa kaboni wazitsulo zili pakati pa 0.6% ndi 3.0%. Mphamvu ndi kuuma kwa chitsulo cha kaboni kumawonjezeka ndikukula kwa mpweya. Osewera mpweya zitsulo ali ndi ubwino izi: mtengo wotsika kupanga, mphamvu apamwamba, kulimba bwino ndi plasticity apamwamba. Chitsulo cha kaboni chingagwiritsidwe ntchito popanga zinthu zomwe zimanyamula katundu wolemera, monga mipando yazitsulo yazitsulo ndi makina osindikizira a hayidiroliki pamakina olemera. Itha kugwiritsidwanso ntchito kupanga magawo omwe ali ndi mphamvu zazikulu komanso zovuta, monga mawilo, ma coupler, ma bolsters ndi mafelemu ammbali munjanji.
2. Ndikutaya aloyi zitsulo. Zotayidwa aloyi zitsulo akhoza kugawidwa mu pulasitala otsika aloyi zitsulo (zinthu okwana aloyi ndi zosakwana kapena wofanana 5%), pulasitala aloyi zitsulo (zinthu okwana aloyi ndi 5% mpaka 10%) ndi kuponyera mkulu aloyi zitsulo (aloyi okwana zinthu ndizoposa kapena zofanana 10%).
Pogwiritsa ntchito mawonekedwe
1. Zida zoponyera. Osewera chida zitsulo akhoza kugawidwa mu kuponyera chida zitsulo ndi kuponyera nkhungu zitsulo.
2. Kuponya chitsulo chapadera. Akuponya zitsulo wapadera akhoza kugawidwa mu pulasitala zosapanga dzimbiri, kuponyera kutentha zosagwira zitsulo, kuponyera avale zosagwira zitsulo, kuponyera aloyi faifi tambala ofotokoza, etc.
3.Ponyani chitsulo cha zomangamanga ndi kapangidwe kake. Osewera zitsulo kwa zomangamanga ndi kapangidwe akhoza kugawidwa mu pulasitala mpweya structural zitsulo ndi pulasitala aloyi structural zitsulo.
4.Ponyani aloyi zitsulo. Ikhoza kugawidwa kukhala chitsulo chochepa kwambiri, kuponyera chitsulo chosakanikirana ndi kuponyera chitsulo chachikulu.
Zitsulo zopangidwa ndi 304 ndi 316 ndizomwe zimagwiritsidwa ntchito kwambiri. Zonsezi ndi ma austenitic cast steels, osakhala maginito kapena maginito ofooka. 430, 403, ndi 410 ndizitsulo zosapanga dzimbiri za austenitic-ferritic zokhala ndi maginito.
▶ Zopangira za Cast Steel malinga ndi kapangidwe kake kapangidwe kazomwe zimakonzedwa ndi makina.
