I-Master Alloys

I-master alloy iyinsimbi eyisisekelo efana ne-aluminium, i-magnesium, i-nickel, noma ithusi ehlanganiswe nephesenti eliphezulu ngokuqhathaniswa lesici esisodwa noma ezimbili. Yenzelwe ukusetshenziswa njengezinto zokusetshenziswa yimboni yensimbi, yingakho sibize i-master alloy noma imikhiqizo esekwe i-alloy semi-finished. Ama-master alloys akhiqizwa ngezindlela ezehlukene njenge-ingot, amapuleti we-waffle, izinduku kumakhoyili nokunye.

1. Ayini ama-alloys ayinhloko?
I-master alloy yi-alloy material esetshenziselwa ukubunjwa okunembe ngokucwenga, ngakho-ke i-master alloy ibizwa nangokuthi i-casting master alloy. Isizathu sokuthi kungani i-master alloy ibizwa ngokuthi "i-master alloy" yingoba inezici zofuzo ezinamandla njengesisekelo sokusakazwa, okusho ukuthi, izici eziningi ze-master alloy (njengokusabalalisa i-carbide, usayizi wokusanhlamvu, isakhiwo sesithombe sesibuko esincane. ), Ngisho nokufaka izakhiwo zemishini nezinye izici eziningi ezithinta ikhwalithi yemikhiqizo yokusakazwa) izotholwa njengefa ekubunjweni ngemva kokuncibilika nokuthululwa. Izinto ezisetshenziswa kabanzi ezisetshenziswa kabanzi ezihlanganisa ingxubevange yokushisa ephezulu esezingeni eliphezulu, ama-alloys ensimbi amelana nokushisa, ama-alloys ayinhloko ezigaba ezimbili, kanye nama-alloys ayinhloko ensimbi engenasici.

2. I-Master Alloys Isicelo
Kunezizathu eziningi zokwengeza ama-alloys ayinhloko ekuncibilikeni. Olunye uhlelo lokusebenza oluyinhloko ukulungisa ukwakheka, okungukuthi ukushintsha ukwakheka kwensimbi ewuketshezi ukuze kubonakale ukucaciswa kwamakhemikhali okucacisiwe. Olunye uhlelo lokusebenza olubalulekile ukulawulwa kwesakhiwo - ukuthonya i-microstructure yensimbi enqubweni yokuphonsa kanye nokuqiniswa ukuze kuhluke izici zayo. Izakhiwo ezinjalo zihlanganisa amandla emishini, i-ductility, i-conductivity kagesi, i-castability, noma ukubukeka kwendawo. Ukubala ekusetshenzisweni kwayo, i-master alloy ngokuvamile ibizwa nangokuthi "i-hardener", "i-grain refiner" noma "i-modifier".
