Kushandiswa uye hunhu hwegraphite sagger crucible

Crucible inogona kushandiswa kusimba kupisa kwenhamba yakawanda yemakristasi. Crucible inogona kukamurwa kuitagraphite crucibleuyequartz crucible. Graphite crucible ine yakanaka yekupisa conductivity uye yakakwirira tembiricha kuramba; Mukushanda kwekushisa kwepamusoro, iyo coefficient yekuwedzera kwekushisa iduku zvikuru. Iine simba rakasimba rinopikisa kupisa kwakanyanya uye kutonhora. Inopikisa kune yakasimba acid uye alkali. Inokodzera kupisa zvakasiyana-siyana zvemvura; Pamusoro pemakemikari, magirafu crucibles anoshandiswa zvakanyanya musimbi, kukanda, michina, indasitiri yemakemikari nemamwe madhipatimendi; Iyo girafu crucible inogadzirwa neyakasikwa graphite zvinhu, iyo inochengetedza yepakutanga yakanakisa kupisa kwakakosha moto kupisa kwegraphite. Iyo graphite crucible inonyanya kushandiswa kunyungudutsa simbi dzisina-ferrous semhangura, aluminium uye alloy. Pane zvisingaverengeki maficha egraphite crucible pachayo. Pano tichanyora muchidimbu imwe kana maviri kwauri.
1. Kusvibiswa kushoma, nekuti simba rakachena rakadai segasi rechisikigo kana gasi rakanyungudutswa rinogona kushandiswa sehuni uye kusvibiswa kushoma.
2. Kuderera kwesimba rekushandisa, nokuti girafu crucible ine kuronga kunonzwisisika, chimiro chepamusoro uye zvinyorwa zvitsva. Mushure mokuedzwa, kushandiswa kwesimba kwakaderera pane iyo yemhando imwechete yevira.
Resistance furnace yakakwirira kuchena graphite crucible inonyanya kushandiswa kunyungudutsa goridhe, sirivheri uye isingawanzo simbi.Ceramic cruciblesanonyanya kushandiswa mumarabhoritari uye kunyungudutswa kweplatinamu, goridhe uye zvisingawanzo simbi. Ko iyo graphite crucible inogona kushandiswa pakupisa kwakanyanya kwe2000 ℃ pasi pemamiriro emhepo? Ichaora uye oxidize nechisimba? Ichaviga simbi yakanyungudutswa here? Chinhu chinonyanya kukosha ndechekuti carburizing inouraya. Mumamiriro ezvinhu akajairika, inogona kusvika 2000 madhigirii mumhepo, asi ichaita oxidize nekukurumidza. Dambudziko resimbi carburization rinofanira kuvapo. Ikozvino pane yakakosha anti carburizing coating pamusika, iyo ine runyerekupe rwekuita zvakanaka.
