Zida Zotayika Zotayika za Wax ya Cast Carbon Steel

China OEM mwambo mpweya zitsulo castings ndianataya sera ndalama kuponyerandi CNC mwatsatanetsatane Machining. Akupezeka kalasi kuchokera low carbon zitsulo, sing'anga mpweya zitsulo kuti mkulu mpweya zitsulo malinga specifications osiyana.

Carbon alloy ndi gulu la iron-carbon alloy yokhala ndi zinthu zina zomwe zimasowa mankhwala monga Si, Mn, P ndi S. Malinga ndi kuchuluka kwa mpweya wa carbon, carbon steel for casting imagawidwa kukhala chitsulo chochepa cha carbon, medium carbon steel ndi high carbon steel. Zitsulo za kaboni zamayiko onse padziko lapansi nthawi zambiri zimasankhidwa molingana ndi mphamvu zawo, ndipo magiredi ofanana amapangidwa. Pa kutentha komweko, fluidity ya chitsulo chosungunuka chokhala ndi zinthu zosiyanasiyana za carbon ndi yosiyana. Chifukwa zitsulo zokhala ndi mpweya wosiyanasiyana zimakhala ndi magawo osiyanasiyana a chitukuko mu dendrites. Kutentha kwakukulu kwa nthawi ya crystallization zone (kusiyana kwa kutentha pakati pa mzere wa liquidus ndi mzere wa solidus), kumapangitsa kuti makristasi a dendritic a carbon steel apangidwe, ndiko kuti, kuwonjezereka kwa chitsulo chosungunuka, chomwe chimayambitsa kuthekera kwachitsulo chosungunuka kudzaza nkhungu.

Ponena za mankhwala a carbon steel, kupatulapo phosphorous ndi sulfure, palibe zoletsa kapena malire apamwamba pa zinthu zina za mankhwala. Pansi pa zomwe tafotokozazi, kapangidwe kake kachitsulo ka kaboni kachitsulo kamatsimikiziridwa ndi mazikowo malinga ndi zomwe zimafunikira makina.

Njira zochizira kutentha kwacarbon steel castingsNthawi zambiri amakhala annealing, normalizing kapena normalizing + tempering. Kwa ena apamwamba mpweya zitsulo castings, quenching ndi tempering angagwiritsidwenso ntchito, mwachitsanzo, quenching + mkulu kutentha tempering, kuti patsogolo mabuku mawotchi zimatha castings mpweya zitsulo. Zitsulo zazing'ono za carbon zitsulo zimatha kuzimitsidwa mwachindunji ndi kutenthedwa kuchokera ku dziko la as-cast. Kwa zazikulu kapena zovuta zooneka ngati carbon steel castings, ndi koyenera kuchita quenching ndi kutentha mankhwala pambuyo normalizing mankhwala.

Ubwino wa Investment Casting:
✔ Kumaliza kwabwino komanso kosalala pamwamba
✔ Kulekerera kolimba kwambiri.
✔ Mawonekedwe ovuta komanso otsogola okhala ndi kusinthasintha kwamapangidwe
✔ Kutha kuyika makoma owonda kwambiri chifukwa chake ndi gawo lopepuka
✔ Kusankhidwa kwakukulu kwazitsulo ndi ma aloyi (zachitsulo komanso zopanda chitsulo)
✔ Kujambula sikofunikira pamapangidwe a nkhungu.
✔ Chepetsani kufunika kwamakina achiwiri.
✔ Kuwononga zinthu zochepa.

Njira Zopangira Investment Casting:
Panthawi yopangira ndalama, phula la sera limakutidwa ndi zinthu za ceramic, zomwe, zikaumitsidwa, zimatenga geometry yamkati ya kuponyedwa komwe kumafunikira. Nthawi zambiri, magawo angapo amawunikiridwa pamodzi kuti agwire bwino ntchito pomangirira phula pa ndodo yapakati yotchedwa sprue. Sera imasungunuka kuchokera papatani - ndichifukwa chake imatchedwanso ndondomeko yotayika - ndipo zitsulo zosungunuka zimatsanuliridwa muzitsulo. Chitsulo chikalimba, nkhungu ya ceramic imagwedezeka, ndikusiya mawonekedwe apafupi a ukonde wofunidwa, kutsatiridwa ndi kutsiriza, kuyesa ndi kuyika.
