Pakati peakasiyana ekukanda maitiro, Stainless simbi inonyanya kukandwa neinvestment casting kanakurasika kukanda wakisi, nekuti ine yakanyanya kurongeka uye ndosaka iyo investment casting ichinziwo precision casting.
Stainless simbi ndiyo chidimbu chesimbi isina tsvina uye acid-resistant simbi. Inonzi Stainless simbi inoshingirira kune zvisina kusimba zvinoodza media zvakaita semhepo, chiutsi, uye mvura. Corrosion simbi inonzi acid-resistant simbi.
Nekuda kwemusiyano wekuumbwa kwemakemikari pakati peyakajairwa Stainless simbi uye acid-resistant simbi, kushora kwavo kusimba kwakasiyana. Stainless simbi yakajairwa kazhinji haimirire kuchemical media corrosion, ukuwo acid-resistant simbi kazhinji isingaite corrosion. Izwi rekuti "stainless simbi" haringorevi rudzi rumwe chete rwesimbi isina tsvina, asi zvakare rinoreva zvinopfuura zana maindasitiri esimbi asina tsvina. Simbi imwe neimwe isina tsvina yakagadziridzwa ine kuita kwakanaka mune yayo chaiyo yekushandisa ndima.
Simbi isina simbi inowanzokamurwa kuita martensitic simbi isina tsvina, ferritic simbi isina tsvina, austenitic simbi isina tsvina,austenitic-ferritic (duplex) simbi isina tsvinauye kunaya kunoomesa simbi isina tsvina zvichienderana nemamiriro e microstructure. Pamusoro pezvo, zvinoenderana nemakemikari ekuumbwa, anogona kukamurwa kuita chromium simbi isina tsvina, chromium nickel simbi isina simbi uye chromium manganese nitrogen simbi isina tsvina, nezvimwe.
Mukugadzira kugadzirwa, mazhinji eStainless simbi castings anopedzwa nekukandira kwekudyara. Iyo yepamusoro yesimbi isina simbi castings inogadzirwa neinvestment casting yakatsetseka uye iyo dimensional kurongeka kuri nyore kudzora. Zvechokwadi, mari yeInvestment kukanda Stainless simbi zvikamuyakakwira zvakanyanya kana ichienzaniswa nemamwe maitiro uye zvinhu.
Investment casting, inonziwo precision casting kana kurasika wax casting, inoshandiswa zvakanyanya sezvo ichipa asymmetrical casting ine ruzivo rwakanaka kwazvo kuti igadzirwe zvisingadhure. Maitirwo acho anosanganisira kugadzira simbi yekukandwa uchishandisa mold inonamira yakagadzirwa kubva patani yewakisi. Matanho anowanikwa mukuita kana kurasika kukanda wakisi ndeaya:
• Gadzira wax pattern kana replica
• Paridza patani yewakisi
• Isai patani yewakisi
• Bvisa patani yewakisi nekuipisa (mukati mechoto kana mumvura inopisa) kugadzira mold.
Kumanikidza kudira simbi yakanyungudutswa muforoma
• Kutonhodza uye Kusimbisa
• Bvisa sprue kubva pakukanda
• Pedzisa uye kupukuta akapedzwa mari castings
