Simbi yakakandwa zvinoreva simbi inoshandiswa pakugadzira simbi castings. Simbi yesimbi inofanirwa kushandiswa kana simba rekukanda riine kukwirira uye kushandiswa kwesimbi kukanda hakukwanisi kuita zvinodiwa. Nekudaro, kuyerera kwesimbi yakanyungudutswa yesimbi yakakandwa haina kunaka seyesimbi yakakoswa, saka ukobvu hwechinhu chinodururwa hachifanirwe kunge chiri chidiki uye chimiro hachifanirwe kuve chakanyanya kuomarara. Kana iyo yesilicon yezvinyorwa ichidzorwa kumucheto wepamusoro, iko kuyerera kwesimbi yakanyungudutswa kunogona kuvandudzwa.
Simbi yesimbi inogona kukamurwa kuita simbi yekukanda simbi uye kukanda kabhoni simbi zvinoenderana nemakemikari ayo, uye inogona zvakare kukamurwa kuita simbi yekushandisa simbi, kukanda yakakosha simbi, mainjiniya uye dhizaini kukanda uye kukanda chiwanikwa simbi zvinoenderana nehunhu hwayo.
Nekuumbwa kwemakemikari
1. Kanda kabhoni simbi. Kanda simbi nekabhoni sechinhu chikuru chekuisa zvinhu uye zvishoma zvezvimwe zvinhu. Kanda kabhoni simbi inogona kukamurwa kuita yakakandwa yakadzika kabhoni simbi, kukanda wepakati kabhoni simbi uye kukanda yakakwira kabhoni simbi. Iyo kabhoni yezvakakandirwa yakadzika kabhoni simbi iri pasi pe0.25%, iyo kabhoni yezvinhu yakakandwa kabhoni simbi iri pakati pe0.25% uye 0.60%, uye iyo kabhoni yezvinhu yakakandwa yakakwira kabhoni simbi iri pakati pe0.6% ne3.0%. Iko kusimba uye kuomarara kwesimbi kabhoni simbi inowedzera pamwe nekuwedzera kwekabhoni yezvinhu. Kanda kabhoni simbi ine zvinotevera zvakanakira: yakaderera kugadzirwa mutengo, simba rakakwirira, kusimba kuri nani uye yakakwirira mapurasitiki. Kanda kabhoni simbi inogona kushandiswa kugadzira zvikamu zvinotakura zvinhu zvinorema, senge simbi inoyerera zvigadziko uye hydraulic yekudhinda mabhesheni mune anorema michina Iyo inogona zvakare kushandiswa kugadzira zvikamu zvinoiswa pasi pemasimba makuru uye kukanganisa, senge mavhiri, couplers, bolsters uye mativi mafuremu pazvitima mota.
2. Kanda chiwanikwa chesimbi. Kukanda chiwanikwa simbi inogona kukamurwa kukanda yakaderera chiwanikwa simbi (iyo yakazara chiwanikwa zvinhu zvakaderera kana zvakaenzana ne5%), kukanda chiwanikwa simbi (iyo yakazara chiwanikwa zvinhu zviri 5% kusvika 10%) uye kukanda yakakwira chiwanikwa simbi (iyo yakazara chiwanikwa zvinhu zvakakura kupfuura kana zvakaenzana 10%).
Nekushandisa hunhu
1. Kukanda mudziyo simbi. Kukanda chishandiso simbi inogona kukamurwa kukanda chishandiso simbi uye kukanda chakuvhuvhu simbi.
2. Kukanda simbi yakakosha. Kukanda simbi yakasarudzika inogona kukamurwa kuita simbi isina kukanda, kukanda simbi isina kupisa, kukanda simbi isingachapfeke, kukanda nickel-based alloy, nezvimwe.
3. Kanda simbi yeinjiniya uye chimiro. Simbi yesimbi yeinjiniya uye chimiro inogona kukamurwa kuita cast kabhoni simbi simbi uye yakakanda chiwanikwa chimiro chesimbi.
4. Kanda chiwanikwa chesimbi. Inogona kukamurwa kukanda yakaderera chiwanikwa simbi, kukanda wepakati chiwanikwa simbi uye kukanda yakakwira chiwanikwa simbi.
304 uye 316 simbi yakakandwa ndiyo simbi dzinoshandiswa zvakanyanya simbi foundries. Ose ari maviri austenitic cast steels, asiri-magineti kana asina kusimba magineti. I430, 403, uye 410 ndeayaustenitic-ferritic simbi isina tsvina ine magnetic properties.
Mukugadzirwa kwesimbi castings, kukanda simbi yekunyungudika inzira yakakosha. Pamberi pekudurura kwega kwega, kuongororwa kwechoto chisati chavepo kunodiwa. Chiyero chechimwe nechimwe chemakemikari chinofanira kusangana nezvinodiwa nevatengi uye zvinoshandiswa zvinoshandiswa.
Kuti uwedzere kunyungudika nekumhanya uye nekuona mhando yeanokanda, ingots ine anokwanisa scouring kuumbwa anowanzo shandiswa kunze kwenyika. Nekudaro, mumatangi eChinese, zvigadzirwa zvesimbi zvinoshandiswa kunyungudika zvakakamurwa kuita mhando mbiri: zvishandiswazve zvigadzirwa uye zvitsva zvinhu. Zvinhu zvakashandiswazve zvinoreva kudurura nekusimudza sisitimu yekukanda, zvigadzirwa zvakakandwa, nezvimwe zvisati zvashandiswa, makemikari uye giredhi rinofanira kuongororwa zvakajeka, uye tsvina yepasi uye chiyero che oxide chinofanira kubviswa nekupfura nenyunje kana sandblasting, wozoisa padivi , kana kuti chinhu chakashandiswazve chinofanira kunyungudutswa uye chinodururirwa mumaingoti ekushandisa.
Zvishandiso zvitsva ingots inogadzirwa nemamwe mamakisi esimbi mabara kana zvimedu, pamwe neanowanzo shandiswa ferroalloys uye yakachena simbi zvinhu. Iyo simbi mbariro uye ingots yemamwe mamakisi inoda kuongororwa kuti iumbwe uye inosangana nematanho, uye saizi yemabhawa inoda kuenderana nehukuru hwesimba remoto uye crucible.
