Nyumba ya Carbon Steel Lock ndi Kutaya Sera

Malinga ndi zomangira zosiyanasiyana zomanga zipolopolo, zopangira ndalama zitha kugawidwa mu silika sol binder Investment casting, madzi galasi binder kuponyera ndalama ndi kuponyera ndalama ndi zosakaniza monga binder zipangizo. Silica sol ndizomwe zimapangidwira m'madzi zomwe zimakhala ndi silicic acid colloid. Ndi polima colloidal njira imene kwambiri omwazikana silika particles sungunuka m'madzi. Ma colloidal particles ndi ozungulira ndipo ali ndi mainchesi a 6-100 nm. Njira yopangira ndalama kuti ipange chipolopolo ndi njira ya gelling. Pali zinthu zambiri zomwe zimakhudza gelation, makamaka electrolyte, pH, sol concentration ndi kutentha. Pali mitundu yambiri yazitsulo zamalonda za silika, ndipo zomwe zimagwiritsidwa ntchito kwambiri ndi zamchere zamchere zamchere zomwe zili ndi silica 30%. Pofuna kuthana ndi zofooka za chipolopolo chautali wa chipolopolo cha silica sol, silika yowuma mofulumira yapangidwa m'zaka zaposachedwa. Njira yopangira chipolopolo cha silica sol ndiyosavuta. Njira iliyonse ili ndi njira zitatu: zokutira, kupukuta mchenga, ndi kuyanika. Njira iliyonse imabwerezedwa kangapo kuti mupeze chipolopolo cha multilayer cha makulidwe ofunikira.

Popanga chipolopolo cha silika, kuyanika ndiye njira yofunika kwambiri. Kupyolera mu kuyanika, madzi amasungunuka, silika sol gels, ndi refractory particles amalumikizana mwamphamvu pamodzi, motero amapeza chipolopolo champhamvu kwambiri. Uku ndikukonzekera bwino kwa kuponyera kotsatira. Kuponyedwa komwe kumapangidwa ndi silika sol kupanga njira kumakhala ndi roughness yotsika, yolondola kwambiri komanso kuzungulira kwa zipolopolo zazitali. Njirayi imagwiritsidwa ntchito kwambiri popangira ma alloys osatentha kwambiri kutentha, zitsulo zosagwira kutentha, zitsulo zosapanga dzimbiri, zitsulo za kaboni, zotayira zochepa, zotayira za aluminiyamu ndi zida zamkuwa.

Silica sol mwatsatanetsatane wotayika wax investment casting process ndi yoyenera kupanga mobwerezabwereza zigawo za mawonekedwe a ukonde kuchokera ku zitsulo zosiyanasiyana ndi ma aloyi ochita bwino kwambiri. Ngakhale kuti nthawi zambiri amagwiritsidwa ntchito popanga zing'onozing'ono, njirayi yakhala ikugwiritsidwa ntchito popanga mafelemu a zitseko za ndege zonse, zokhala ndi zitsulo zokwana 500 kgs ndi aluminiyumu mpaka 50 kgs. Poyerekeza ndi njira zina zoponyamo monga kufa kapena kuponya mchenga, zitha kukhala zodula. Komabe, zida zomwe zitha kupangidwa pogwiritsa ntchito kuyika ndalama zimatha kuphatikiza ma contours ovuta, ndipo nthawi zambiri zidazo zimayikidwa pafupi ndi mawonekedwe a ukonde, motero zimafunikira kukonzanso pang'ono kapena kusasinthidwa kamodzi.

Malinga ndi mlingo wa carbon zili, mpweya zitsulo poponya zambiri ogaŵikana otsika mpweya zitsulo, sing'anga mpweya zitsulo ndi mkulu mpweya zitsulo. Zitsulo za kaboni zamayiko onse padziko lapansi nthawi zambiri zimasankhidwa molingana ndi mphamvu zawo, ndipo magiredi ofanana amapangidwa.

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 zopangira zitsulo za kaboni nthawi zambiri zimakhala zokhazikika, zokhazikika kapena zokhazikika + zotentha. 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.

Pankhani yamakampani opanga zitsulo ndizitsulo, zitsulo zachitsulo zimatanthawuza zitsulo ndi ma alloys awo omwe ali ndi chitsulo. Chitsulo chachitsulo chimaphatikizapo chitsulo ndi chitsulo cha nkhumba ndipo mazikowo amawagawa m'magulu awiri akuluakulu: chitsulo (imvi kuponyedwa chitsulo, chitsulo chosungunula, chitsulo chosungunuka, chitsulo chosungunuka, vermicular graphite cast iron etc.) aloyi zitsulo, zitsulo zosapanga dzimbiri etc). Ndi njira yotayira thovu yotayika, RMC Casting Foundry imatha kuthira chitsulo chotuwira, chitsulo cha ductile, chitsulo cha alloy ndi carbon steel.
