Pane misiyano yakakura pakatisilicon carbide cruciblesuye magirafu crucibles mune zvakawanda zvinhu senge zvinhu, maitiro, kuita, uye mitengo. Iyi misiyano haingokanganisa maitiro ayo ekugadzira, asiwo inotarisisa kushanda kwayo uye mamiriro ekushandisa.
musiyano mukuru
Graphite crucibles inonyanya kugadzirwa neakasikwa flake graphite uye inoshandisa ivhu sebhainda. Musanganiswa uyu unopa iyo graphite crucible yakanakisa yekupisa yekupisa uye yakakwirira tembiricha kuramba, ichiita kuti ive yakakodzera kunyorera mune yakanyanya-tembiricha kunyungudika maitiro. Iyo yakasarudzika dhizaini uye yakakwira yekupisa conductivity yemasikirwo flake graphite inoita kuti magirafu crucible azivikanwe zvakanyanya mumetallurgical uye foundry maindasitiri.
Silicon carbide crucible yakavakirwa pachisikigo flake graphite, ine silicon carbide sechinhu chikuru chikamu uye yakakwirira-tembiricha resin sebinder. Sechinhu chakanyanya kuoma, silicon carbide ine yakanyanyisa kupfeka kuramba uye kugadzikana kwemafuta, ichibvumira silicon carbide crucibles kushandiswa munzvimbo dzakaoma. Iko kushandiswa kweyepamusoro-tembiricha resin zvakare inosimudzira iyo crucible simba rose uye kusimba.
Maitiro akasiyana
Iyo yekugadzira maitiro e graphite crucible inonyanya kutsamira pane manual uye mechanic kudzvanya. Madiki ma graphite crucibles anowanzo umbwa nekutsikirira kwemechani, obva apinzwa muchoto pane tembiricha ye1,000 madhigirii, uye pakupedzisira akaputirwa ne-anti-corrosion glaze kana hunyoro-ufakazi pendi kuti iwedzere kusimba uye kusagadzikana kwemarara. Iyi tsika yechinyakare, kunyangwe ichidhura-inoshanda, ine painogumira maererano nekubudirira kwekugadzira uye kuenderana kwemhando.
Iyo yekugadzira maitiro esilicon carbide crucible iri kumberi, uchishandisa isostatic yekutsikirira midziyo uye sainzi fomula. Isostatic yekutsikirira tekinoroji inoshandisa yunifomu kudzvanywa (kusvika ku150 MPa), zvichikonzera kuwanda kwepamusoro uye kuenderana mune crucible. Iyi nzira haingonatsiridza simba re crucible's mechanical, asiwo zvakanyanya kuwedzera kupikisa kwayo kutyisa kwekupisa uye corrosion.
Kusiyana kwemaitiro
Panyaya yekushanda, kune misiyano yakakura pakati pegirafu crucibles uye silicon carbide crucibles. Graphite crucibles ine density ye13 kA/cm², nepo silicon carbide crucibles ine density ye1.7 kusvika 26 kA/mm². Hupenyu hwesevhisi hwema graphite crucibles hunowanzo 3-5 nguva yesilicon carbide crucibles, iyo inonyanya kukonzerwa nehukuru hwezvinhu zvesimba uye kuomarara kuramba kwesilicon carbide crucibles.
Uye zvakare, musiyano wetembiricha pakati pemukati nekunze kwe graphite crucible ungangoita madhigirii makumi matatu nemashanu, nepo musiyano wetembiricha wesilicon carbide crucible unongova 2-5 madhigirii, zvichiita kuti silicon carbide crucible ive yepamusoro-soro maererano nekudzora tembiricha uye kupisa. kugadzikana. Iyo asidhi uye alkali kuramba uye corrosion resistance yesilicon carbide crucibles zvakare yakakwira zvakanyanya kupfuura iyo yemagraphite crucibles, iyo inovandudza zvakanyanya kushanda kwesimba uye inochengetedza ingangoita 50% simba pane graphite crucibles.
musiyano mumutengo
Nekuda kwekusiyana kwezvinhu uye maitiro ekugadzira, graphite crucibles uye silicon carbide crucibles zvakare ane yakakosha mitengo misiyano. Kazhinji, silicon carbide crucibles inodhura zvakapetwa katatu pane graphite crucibles. Uyu mutsauko wemutengo unoratidza zvakakosha zvakanakira silicon carbide crucibles maererano nemutengo wezvinhu, kugadzira maitiro kuoma uye kuita.
Muchidimbu, kunyangwe silicon carbide crucibles inodhura zvakanyanya, kusimba kwayo kwepamusoro, kusagadzikana kwekuora, uye kushanda nesimba kunoita kuti ive sarudzo inodhura kune akawanda anoda maapplication. Graphite crucibles inoramba ichishandiswa zvakanyanya mumazhinji echinyakare maapplication nekuda kwemutengo wakaderera uye yakanaka yekutanga zvivakwa. Izvo zvakanakira zvakanakira uye zvakaipira zveaya maviri crucibles anoona kuti akakodzera kune akasiyana ekushandisa mamiriro.
