Silicon Yekukanda Metal

Metal casting inzira yechinyakare yave yakakosha kubudiriro yevanhu kwemazana emakore. Kubva pakugadzira zvivezwa zvakaoma kusvika pakugadzira zvikamu zvemaindasitiri zvakaomarara, kukanda simbi kunoita basa rakakosha mumaindasitiri akasiyana.Silicon, chinhu chinowanzobatanidzwa nehunyanzvi hwepamusoro, ndechimwe chezvinhu zvinobatsira kumunhu. Inonyanya kushandiswa kugadzira aluminium-silicon alloysuyeferrosilicon(iron-silicon) alloys, ine zvakare yakakosha kukanganisa kwesimbi yekukanda maitiro. China, Russia, Norway, neBrazil ndidzo dzinonyanya kugadzira zvicherwa zvesilicon. Muchinyorwa chino, tichatora kunyura kwakadzika mukushandiswa kwesilicon mukukanda simbi, tichiongorora zvimiro zvayo, mashandisirwo, uye nzira dzainosimudzira kukanda.

Kunzwisisa Silicon muMetal Casting

Silicon chinhu chakasiyana-siyana chinoshandiswa zvakanyanya mukukanda simbi nekuda kwezvakasiyana zvimiro. Kana yakasanganiswa nesimbi senge aruminiyamu, mhangura, uye simbi, silicon inosimudzira kusimba, kuoma, uye kusaita ngura kweiyo alloy inoguma. Izvi zvakagadziridzwa zvemichina zvinoita kuti masilicon alloys anyanya kukosha mumaindasitiri uko kusimba uye kuita kwakakosha.

Nei Silicon Yakakodzera Kukandira Metal

High Melting Point: Silicon ine yakakwira yekunyungudika, ichiita kuti ive yakakodzera kune yakakwira-tembiricha maapplication akadai sekukanda simbi.
Low Thermal Kuwedzera: Silicon ine yakaderera thermal kuwedzera pfuma, iyo inobatsira kuderedza njodzi yekupisa kunetseka panguva yekukanda.
Mvura yakanaka: Silicon inonatsiridza kuyerera kwesimbi yakanyungudutswa, ichibvumira kuti iyerere nyore nyore mumhando dzakaoma uye mapako.
Simba rakawedzerwa: Silicon inowedzera kusimba uye kuoma kwesimbi alloys, ichiita kuti ive yakanakira maapplication ayo anoda yakakwira mechanical zvivakwa.

Zvishandiso zveSilicon muMetal Casting

1. Aluminium Casting: Silicon inowanzoshandiswa mukukanda aluminium kuti ivandudze michina ye alloy. Aluminium-silicon alloys ane huremu uye ane yakanakisa corrosion resistance, zvichiita kuti ive yakanakira aerospace uye mota kunyorera.

2. Simbi: Musimbi yakakandwa, silicon inowedzerwa kune grey iron kukurudzira kuumbwa kwe graphite flakes, iyo inosimudzira machinability yezvinhu uye kunyorova zvinhu. Silicon zvakare inovandudza kupfeka kuramba kweferroalloys.

3. Cast Steel: Silicon inoshandiswa musimbi yakakandwa kuti deoxidize simbi yakanyungudutswa uye kunatsiridza fluidity yayo. Silicon inobatsirawo kudzora saizi yezviyo zvesimbi, zvichikonzera kusimba, kuchinjika kukanda.

Basa reSilicon muKusimudzira Maitiro ekukanda

Kuvandudzwa kwemvura: Silicon inonatsiridza kuyerera kwesimbi yakanyungudutswa, ichibvumira kuti ive nyore kuzadza makomba akaomarara. Ichi chivakwa chakakosha kuti uwane yakaoma uye yakadzama castings.

Yakaderedzwa Shrinkage: Kuwedzera silicon kune simbi alloys kunobatsira kuderedza shrinkage kuremara mukukandira, kuve nechokwadi chekuita kwedimensional uye kuderedza kudiwa kwekuwedzera machining.

Enhanced Machinability: Machinability iri nyore kugadzirisa. Ichi chivakwa chinonyanya kubatsira mumashandisirwo anoda post-casting machining.

Matambudziko uye Mafungiro

Nepo silicon ichipa akawanda mabhenefiti mukukanda simbi, kune zvakare mamwe matambudziko ekufunga nezvawo:

1. Brittleness: Kunyanya kukwira kwesilicon content kunogona kukonzera alloy brittleness, iyo inogona kukanganisa maitiro ayo emagetsi. Yakakodzera alloy dhizaini uye silicon yemukati yekutonga yakakosha kudzivirira dambudziko iri.

2. Porosity: Kana isina kudzorwa zvakanaka, silicon inogona kuwedzera njodzi yeporosity mukukanda. Kungwarira machining uye yakasimba kudzora mhando matanho anofanira kutorwa kuderedza porosity.

3. Mutengo: Silicon chinhu chinodhura chinokanganisa mari yose yekugadzira silicon-containing alloys. Kuongororwa kwemutengo-kubatsirwa kunokosha kuti uone kugona kwekushandisa silicon mune imwe nzira yekukanda.
