Gabatarwa zuwa Garin Dumama
Lokacin zabar kayan don abubuwan dumama, gami biyu akai-akai suna la'akari:Nichrome(Nickel-Chromium) daFeCrAl(Iron-Chromium-Aluminum). Duk da yake dukansu biyu suna aiki iri ɗaya a cikin aikace-aikacen dumama masu tsayayya, suna da halaye daban-daban waɗanda suka sa su dace da yanayi daban-daban da aikace-aikace. Fahimtar waɗannan bambance-bambance yana da mahimmanci don zaɓar kayan da ya dace don takamaiman bukatunku.
1.Composition da Basic Properties
Nichrome alloy ne na nickel-chromium yawanci yana ƙunshe da 80% nickel da 20% chromium, kodayake akwai sauran rabo. Wannan haɗin yana ba da kyakkyawar juriya ga iskar shaka kuma yana kula da ƙarfi a yanayin zafi. Nichrome alloys an san su don ƙayyadaddun tsari da daidaiton aiki a cikin kewayon zafin jiki mai faɗi.
FeCrAl alloys, kamar yadda sunan ke nunawa, sun ƙunshi baƙin ƙarfe (Fe) tare da ƙarin ƙarin abubuwan chromium (Cr) da aluminum (Al). Abun da aka gama gama gari zai iya zama 72% ƙarfe, 22% chromium, da 6% aluminum. Abubuwan da ke cikin aluminium musamman suna haɓaka aikin gawa mai zafin jiki da juriya na iskar shaka.
2.Ayyukan Zazzabi
Ɗaya daga cikin bambance-bambance mafi mahimmanci shine a cikin iyakar yanayin yanayin aiki:
Nichrome yawanci yana aiki har zuwa 1200°C (2192°F)
- FeCrAl na iya jure yanayin zafi har zuwa 1400°C (2552°F)
Wannan yana sa FeCrAl ya zama mafi girma don aikace-aikacen da ke buƙatar zafi mai tsanani, kamar tanderun masana'antu ko kayan aikin dakin gwaje-gwaje masu zafi.
3.Oxidation Resistance
Dukansu alloys suna samar da matakan kariya na oxide, amma ta hanyoyi daban-daban:
- Nichrome yana samar da Layer chromium oxide
- FeCrAl yana haɓaka Layer aluminum oxide (alumina).
Layer na alumina a cikin FeCrAl ya fi kwanciyar hankali a yanayin zafi sosai, yana samar da mafi kyawun kariya na dogon lokaci daga iskar shaka da lalata. Wannan ya sa FeCrAl ke da mahimmanci musamman a cikin mahalli masu yuwuwar abubuwa masu lalata.
4.Electrical Resistivity
Nichrome gabaɗaya yana da ƙarfin juriya na lantarki fiye da FeCrAl, wanda ke nufin:
- Nichrome na iya samar da ƙarin zafi tare da adadin halin yanzu
- FeCrAl na iya buƙatar ɗan ƙara na yanzu don daidaitaccen dumama
Koyaya, juriya na FeCrAl yana ƙaruwa sosai tare da zafin jiki, wanda zai iya zama fa'ida ga wasu aikace-aikacen sarrafawa.
5.Mechanical Properties and Formability
Nichrome gabaɗaya ya fi ductile da sauƙin aiki tare da zafin jiki, yana sa ya fi dacewa don aikace-aikacen da ke buƙatar sifofi masu rikitarwa ko lanƙwasa. FeCrAl yana zama mafi ductile lokacin zafi, wanda zai iya zama fa'ida yayin tafiyar matakai amma yana iya buƙatar kulawa ta musamman a zafin daki.
6.Tsarin Kudi
FeCrAl Alloys yawanci farashin ƙasa da Nichrome saboda suna maye gurbin tsadanickelda baƙin ƙarfe. Wannan fa'idar farashi, haɗe tare da mafi girman aikin zafin jiki, yana sanya FeCrAl zaɓi mai kyau don aikace-aikacen masana'antu da yawa.
Me yasa Zabi samfuranmu na FeCrAl?
Abubuwan dumama na mu na FeCrAl suna ba da:
- Mafi girman aikin zafi (har zuwa 1400 ° C)
- Kyakkyawan iskar shaka da juriya na lalata
- Tsawon rayuwar sabis a cikin matsanancin yanayi
- Madaidaicin farashi mai tsada zuwa ga gami na tushen nickel
- Magani na musamman don takamaiman buƙatun aikace-aikacen ku
Ko kuna ƙirar tanderun masana'antu, tsarin dumama, ko kayan aiki na musamman, samfuran mu na FeCrAl suna ba da dorewa da aiki da ake buƙata don mahalli masu buƙata.Tuntube muyau don tattauna yadda hanyoyin mu na FeCrAl zasu iya biyan buƙatun ku na dumama yayin haɓaka farashin ku na aiki.
