Muindasitiri yekugadzira simbi nekugadzira foundation, kuvimbika kwezvikamu zvinoramba kushanda kunokanganisa zvakananga kushanda zvakanaka kwekugadzira, kuchengetedzeka, uye kunaka kwechigadzirwa. Pakati pezvikamu izvi zvakakosha,Zvidhinha zvekudira pasiHazvina kukosha, zvakagadzirirwa kutsungirira tembiricha yakanyanya, simbi dzakanyungudutswa dzinoora, uye kupisa kwakanyanya ukuwo zvichiita kuti simbi ifambe zvakanaka uye ichidzorwa. Kubva pakugadzirwa kwesimbi kusvika pakuumbwa kwesimbi nemazvo, mashandisirwo adzo akasiyana-siyana anoita kuti dzive dzinokosha pakushanda kwemazuva ano kwekugadzira simbi. Pazasi pane pfupiso yakadzama yekushandiswa kwadzo kukuru uye kukosha kwadzo mumaindasitiri.
1. Core Application: Simbi & Alloy Casting
Kushandiswa kukuru kweZvidhinha zvekudira pasiiri mumabasa ekukanda simbi ne alloy. Sezvikamu zvakakosha zvemasisitimu ekukanda machira, vanoisa machira mumitsetse, vanoumba ma nozzles ekudira, zvidhinha zvezvigaro, uye zvidhinha zvemaoko. Nzira dzavo dzekuyerera dzakagadzirwa nemazvo dzinogonesa kugoverwa kwesimbi yakanyungudutswa yakafanana, isina turbulence, chinhu chakakosha mukuderedza zvikanganiso zvekukanda zvakaita se porosity, inclusions, uye kusarongeka kwepamusoro.
Mumigodhi yesimbi, zvidhinha izvi zvinoita basa rakakosha mukugadzira masystem ekudururira pasi, zvichichengetedza kusimba kwezvipfungaidzo zvesimbi nemakwara panguva yekufambisa simbi yakanyungudutswa.Mhando dzealuminium yakawanda uye mullitezvinodzivirira zvakanyanya simbi yakanyungudutswa uye ngura yetsvina, zvichiwedzera hupenyu hwekushanda kwendiro uye zvichideredza nguva yekushanda kwayo. Pakuumbwa kwe alloy—apo kuumbwa kwemakemikari chaiwo uye kudzora tembiricha zvisingakurukurwi—Zvidhinha zvekudira pasisimbisa kuti mvura inodururwa nguva dzose, kudzivirira kupatsanurwa kwe alloy uye kuwedzera kunaka kwechigadzirwa chekupedzisira.
2. Kuisa Furnace Lining & Thermal Insulation
Kunze kwehurongwa hwekudira,Zvidhinha zvekudira pasianoshandiswa zvakanyanya sezvinhu zvekubatanidza maovheni efoundry, maovheni e arc, uye maovheni e induction. Nekugadzikana kwakanyanya kwekupisa (kusingapindi tembiricha inodarika 1700°C), anochengetedza mukati meovheni zvinobudirira, achideredza kurasikirwa nekupisa uye achivandudza mashandiro esimba. Kudzivirira uku kwekupisa hakungodzikisi mari yekushandisa chete asiwo kunogadzira nzvimbo yakagadzikana yekupisa, yakakosha pakunyungudutsa nekunatswa kwesimbi zvakaenzana.
Kusagadzikana kwavo nekupisa kunodzivirira kutsemuka uye kukuvara kwechimiro nekuda kwekuchinja-chinja kwekushisa, zvichiita kuti chitofu chigare kwenguva refu uye kuderedza kudzima kwekugadzirisa. Semuenzaniso, mukugadzira simbi dzemagetsi, zvidhinha izvi zvinotsigira mashandiro ekubvisa gasi pasi nekuchengetedza kugadzikana kwemhepo uye kudzivirira kukurwa kwesimbi yakanyungudutswa ine simba rakawanda.
3. Kugadzira Zvinhu Zvakanyatsonaka zveMaindasitiri Epamusoro-soro
Makambani ekugadzira zvinhu nemazvo—kusanganisira kugadzira zvinhu zvemuchadenga, zvemotokari, uye zvekushandisa pakurapa—anonyanya kuvimba neZvidhinha zvekudira pasikuti simbi yakanyungudutswa ifambe zvakanaka uye inodzora. Mukugadzira simbi yakanyungudutswa (lost-wax casting), vanogadzirisa mwero wekuyerera kwemvura kuita simbi dzakaoma, vachivimbisa kuzadza kwakazara pasina kukuvadza zvivakwa zvesimbi zvakapfava.
Kuenzana kwemhando yepamusoroZvidhinha zvekudira pasiinobatsirawo mukubvisa utsi hwesimbi yakanyungudutswa, kubvisa tsvina nemabubble emhepo anokanganisa hunhu hwemakanika ezvikamu zvakanyatsonaka. Kune zvikamu zvakakosha zvakaita semabhuroko einjini yemotokari kana zvikamu zvemuchadenga zvinoda simba rakawanda uye kuvimbika, kunyatsoita uku kunoita kuti zvidhinha izvi zvive chikamu chisingatsivike cheketani yekugadzira.

Vagadziri vanopa sarudzo dzakagadzirwa maererano nechimiro, saizi, uye kuumbwa kwezvinhu zvinoenderana nemaitiro chaiwo: Zvidhinha zvakagadzirwa nevhu zvinodhura zvishoma pakukanda zvisina ferrous pakupisa kwepakati (aruminiyamu, mhangura); zvidhinha zvealumina zvine ferrous pakupisa kwakanyanya uye zvinodzivirira ngura zvakanyanya; zvidhinha zvemullite zvakanakira nzvimbo dzakaoma, dzinogara dzichiita semachira ekugadzira simbi, nekuda kwechimiro chadzo chakasimba chinodzivirira kupinda kwesimbi yakanyungudutswa.
Sei Uchifanira Kusarudza Zvidhinha Zvekudira Pasi Zvemhando Yepamusoro?
Kudyara mari muzvidhinha zvepamusoro zvinodira pasi (Bottom Pouring Bricks) zvinoreva kuti zvinhu zvinogadzirwa zvakanaka, nguva shoma yekushanda, uye mitengo yenguva refu inoshandiswa inodzikira.Kugara kwenguva refu uye kugadzikana kwekushanda kwavo kunoita kuti pave nekugadzirwa kwakafanana, nepo kushandiswa kwadzo kwakasiyana-siyana kuchitsigira maitiro akasiyana-siyana ekugadzira simbi. Ingave yekugadzira simbi yakakura kana kugadzira zvikamu zvakanyatsonaka, zvidhinha izvi zvinopa kuvimbika uye kushanda zvakanaka kunodiwa nemakambani emazuva ano ekugadzira simbi.
