Nhanganyaya yeKupisa Alloys
Pakusarudza zvinhu zvekupisa zvinhu, zvinhu zviviri zvinowanzo fungwa nezvazvo:Nichrome(Nickel-Chromium) uyeFeCrAl(Iron-Chromium-Aluminum). Kunyange zvazvo ese ari maviri achishandira zvakafanana mukushandiswa kwekupisa kunodzivisa kupisa, ane hunhu hwakasiyana hunoita kuti akwanise kushandiswa munzvimbo dzakasiyana. Kunzwisisa misiyano iyi kwakakosha pakusarudza zvinhu zvakakodzera zvaunoda.
1. Maumbirwo uye Hunhu Hwakakosha
Nichrome imhando yenickel-chromium inowanzova ne80% nickel uye 20% chromium, kunyange zvazvo paine mamwe ma ratios. Musanganiswa uyu unodzivirira oxidation zvakanaka uye unochengetedza simba pakupisa kwakanyanya. Nichrome alloys inozivikanwa nekuumbwa kwayo uye kushanda kwayo nguva dzose pakupisa kwakasiyana-siyana.
Ma alloys eFeCrAl, sezita rayo, anonyanya kuumbwa nesimbi (Fe) ine chromium (Cr) nealuminium (Al). Chinhu chakajairika chingave 72% iron, 22% chromium, uye 6% aluminum. Huremu hwealuminum hunonyanya kuwedzera kushanda kwealloy pakupisa kwakanyanya uye kuramba oxidation.
2. Kushanda kweTembiricha
Imwe yemisiyano yakakosha iri mukupisa kwavo kwakanyanya kushanda:
- Nichrome inowanzo shanda kusvika pa1200°C (2192°F)
- FeCrAl inogona kutsungirira tembiricha inosvika 1400°C (2552°F)
Izvi zvinoita kuti FeCrAl ive yepamusoro pakushandiswa kunoda kupisa kwakanyanya, senge maovheni emaindasitiri kana michina yemurabhoritari inodziya zvakanyanya.
3.Kuramba kweOxidation
Ma alloys ese ari maviri anoumba ma layers ekudzivirira oxide, asi kuburikidza nenzira dzakasiyana:
- Nichrome inoumba chromium oxide layer
- FeCrAl inogadzira jira realuminium oxide (alumina)
Rutivi rwealumina muFeCrAl rwakasimba zvakanyanya kana tembiricha yakakwira zvikuru, zvichipa dziviriro iri nani kwenguva refu kubva mukuora uye oxidation. Izvi zvinoita kuti FeCrAl ive yakakosha zvikuru munzvimbo dzine zvinhu zvinogona kuora.
4. Kudzivirira Kwemagetsi
Nichrome inowanzova ne resistivity yemagetsi yakakwira kupfuura FeCrAl, zvinoreva kuti:
- Nichrome inogona kuburitsa kupisa kwakawanda nehuwandu hwakaenzana hwemagetsi
- FeCrAl ingangoda simba remagetsi rakati wandei kuti iite kuti kupisa kukwane
Zvisinei, kuramba kweFeCrAl kunowedzera zvakanyanya kana tembiricha yakwira, izvo zvinogona kubatsira kune mamwe mashandisirwo ekudzora.
5. Hunhu hweMichina uye Kuumbwa Kwayo
Nichrome inowanzova yakapfava uye iri nyore kushanda nayo patembiricha yemumba, zvichiita kuti ive yakakodzera kushandiswa pakushandisa kunoda maumbirwo akaomarara kana kuti yakakombama zvakasimba. FeCrAl inova yakapfava zvikuru kana yapiswa, izvo zvinogona kubatsira panguva yekugadzira asi zvinogona kuda kugadziriswa kwakakosha patembiricha yemumba.
6. Zvaunofanira Kufunga Nezvemutengo
Ma alloys eFeCrAl anowanzo kudhura zvishoma pane eNichrome nekuti anotsiva anodhuranikelinesimbi. Iyi mukana wemutengo, pamwe chete nekushanda kwepamusoro-soro pakupisa, zvinoita kuti FeCrAl ive sarudzo inokwezva kune akawanda maindasitiri.
Sei Tichifanira Kusarudza Zvigadzirwa Zvedu zveFeCrAl?
Zvinhu zvedu zveFeCrAl zvinopa:
- Kushanda zvakanaka pakupisa kwepamusoro-soro (kusvika 1400°C)
- Kudzivirira ngura zvakanyanya uye oxidation
- Hupenyu hwebasa hwakareba mumamiriro ezvinhu akaipisisa
- Imwe nzira inoshanda pamutengo wayo isingadhuri pane nickel-based alloys
- Mhinduro dzinogona kugadziriswa kune zvaunoda zvekushandisa
Ungave uri kugadzira maovheni emaindasitiri, masisitimu ekudziyisa, kana michina yakakosha, zvigadzirwa zvedu zveFeCrAl zvinopa kugara kwenguva refu uye kushanda zvakanaka kunodiwa munzvimbo dzinoda kushanda kwakawanda.Taura nesunhasi kuti tikurukure kuti mhinduro dzedu dzeFeCrAl dzingazadzisa sei zvinodiwa nechinhu chako chekupisa uku uchigadzirisa mari yako yekushanda.
