Kugona kuzadza kwesimbi yakanyungudutswa, inozivikanwawo sekuti fluidity, chinhu chakakosha mukukanda maitiro. Zvinoreva kugona kwesimbi yakanyungudutswa kuzadza mhango ye mold zvachose isati yaoma. Kunzwisisa uye nekugonesa ichi chivakwa kwakakosha mukugadzira emhando yepamusoro castings ine yakaoma geometries uye kushoma hurema.
Basic Concept yeKuzadza Mano
Kugona kuzadza kwesimbi yakanyungudutswa kunotarisisa kuti simbi inoyerera sei mukati uye inozadza zvinhu zvakaomarara zve mold. Zvinokonzerwa nezvakati wandei zvinosanganisira kuumbwa kwesimbi, tembiricha, uye magadzirirwo eforoma. Kugona kuzadza kwakanaka kunovimbisa kuti kukanda kwekupedzisira hakuna kukanganisa senge misruns, kutonhora kunovhara, uye zvikamu zvisina kukwana. Iyi pfuma inonyanya kukosha mukugadzirwa kwematete-walled castings uye zvikamu zvine yakaoma geometries.
Zvinhu Zvinokurudzira Kuzadza Mano
1.Metal Composition: Kemikari yesimbi yakanyungudutswa inoita basa rakakosha mukuyerera kwayo. Simbi dzine nzvimbo dzakaderera dzekunyungudika kazhinji dzine mvura iri nani.
2.Tembiricha: Tembiricha yesimbi yakanyungudutswa inoenderana nekuyerera kwayo. Kupisa kwepamusoro kunoderedza viscosity yesimbi, ichiwedzera kukwanisa kwayo kuyerera muforoma. Nekudaro, tembiricha yakanyanya kukwira inogona kukonzera kuwedzera oxidation uye kunyudzwa kwegasi, izvo zvinogona kukonzera kukanganisa mukukanda.
3.Mold Design: Dhizaini uye zvinhu zve mold zvinokanganisa zvakanyanya kugona kuzadza. Mold ine nzvimbo yakatsetseka uye yakakodzera gating masisitimu inofambisa kuyerera kuri nani.
4.Kudira Rate: Muyero wekuti simbi yakanyungudutswa inodirwa muforoma inokanganisa kugona kwayo kuzadza gomba. Chiyero chinodzorwa uye chisingachinjiki chekudira chinovimbisa kuti simbi inochengetedza tembiricha yayo uye kuyerera kwayo, kudzivirira kusimba kusati kwasvika.
5.Additives: Zvimwe zvekuwedzera zvinogona kuunzwa kuvandudza fluidity yesimbi yakanyungudutswa. Semuyenzaniso, silicon inowanzowedzerwa kune aruminiyamu alloys kuti iwedzere kuyerera kwayo, ichiita kuti ive yakakodzera kune yakaoma castings.
Matanho Ekuvandudza Kuzadza Mano
1.Optimal Alloy Selection: Kusarudza alloys ane inherent yakanaka fluidity zvivakwa ndiyo nhanho yekutanga yekuvandudza kugona kuzadza. Semuenzaniso, aruminiyamu-silicon alloys anosarudzwa kune yavo yepamusoro fluidity uye nyore kukanda.
2.Temperature Control: Kuchengetedza tembiricha yakakwana yesimbi yakanyungudutswa mukati mekuita kwekukanda kwakakosha. Preheating mold uye kudzora tembiricha yekudurura inogona kuwedzera zvakanyanya fluidity. Kushandisa tembiricha yekutarisa masisitimu kunobatsira mukuwana mhedzisiro inowirirana.
3.Yakavandudzwa Mold Dhizaini: Kugadzira mold ine nzvimbo dzakatsetseka, mhepo yakakwana, uye yakanyatsorongwa gating masisitimu anogona kufambisa zviri nani kuyerera kwesimbi.
4.Kushandisa Inoculants uye Fluxes: Kuwedzera inoculants inogona kunatsa chimiro chezviyo chesimbi, kuvandudza fluidity yayo. Fluxes inogona zvakare kushandiswa kubvisa kusvibiswa uye kuderedza kushushikana kwepasi, kuwedzera kuyerera maitiro esimbi yakanyungudutswa.
5.Degassing: Kubvisa magasi akanyungudutswa kubva kusimbi yakanyungudutswa kunogona kudzivirira kuumbwa kwemabhuru uye voids, kuvandudza kugona kwekuzadza kwese.
6.Kunodzorwa Kudira Techniques: Kushandisa otomatiki ekudira masisitimu kunovimbisa kuenderana uye kudzorwa kuyerera kwesimbi yakanyungudutswa muforoma. Izvi zvinoderedza mikana yemhirizhonga uye inotonhora inovhara, zvichitungamira kune zvirinani kuzadza kugona.
