Carane ngatasi expansion Nihan saka casting investasi stainless steel?

2022-12-19

Nalika nggawe casting investasi stainless steel,kita kerep ketemu Cacat expansion shell.Shell expansion disababaké déning mode solidification volume saka sekutu wesi cast modular lan expansion graphitization ing proses transformasi eutektik.Ing ngisor iki Tongda bakal pirembagan bab carane ngatasi masalah iki.


1) Kontrol proses kanthi ketat ing tahap awal (bahan bahan lilin, cetakan, posisi las sprue, pengerasan lapisan lan modul garing): Proporsi lilin miturut materi anyar lan lawas 50% saben. Peralatan ngecor yaiku lilin tekanan pneumatik, lilin pemanasan listrik gun injeksi lan kontrol suhu materi lilin antarane 42-50âãWelding lokasi sprue kudu milih ing sih paling gedhe hot spot saka stainless steelâinvestasi castings, supaya éling urutan solidification.Coating karo kekuatan dhuwur Nihan ,bahan lumahing karo wêdakakêna silika, wedhi silika, lapisan tulangan karo aluminium dhuwur, wedhi alumina dhuwur, powder coating rasio Cairan punika 1: 1, supaya nambah kekuatan smearing lan cangkang, nambah 0,05% lapisan surfaktan.


2) Kanggo nyilikake efek kanggo dewaxing expansion Nihan, kita nganggo proses apik minangka nderek: Copot rod lilin sadurunge dewaxing; Nggunakake cara gabungan gabungan, yaiku sistem pouring karo uap banyu pisanan materi lilin nyawiji utawa njupuk kelet lilin, lan banjur ing mundhut banyu panas saka jamur molten, Yahoo iku kanggo éling materi lilin saka nyawiji ing wektu sing padha, kanggo mesthekake yen materi lilin kebanjiran saluran unblocked.


3) Strictly kontrol pouring suhu, casting kacepetan lan pouring tingkat Cairan dhuwur saka castings investasi stainless steel kanggo èfèktif nyuda karusakan saka Nihan sak pouring proses.
