Kushandiswa uye hunhu hwe graphite sagger crucible

Crucible inogona kushandiswa kupisa makristaro akawanda zvakanyanya. Crucible inogona kukamurwa kuitachipfuro chegrafitiuyechipfukidziro chequartz. Graphite crucible ine conductivity yakanaka yekupisa uye inodzivirira kupisa kwakanyanya; Pakushandiswa kwekupisa kwakanyanya, coefficient yekuwedzera kwekupisa idiki kwazvo. Ine simba rakasimba rekudzivirira kupisa kwakanyanya uye kutonhora. Inodzivirira acid yakasimba uye alkali. Yakakodzera kupisa mvura dzakasiyana-siyana; Pamusoro pemakemikari, graphite crucibles inoshandiswa zvakanyanya musimbi, casting, michina, indasitiri yemakemikari nedzimwe nzvimbo; graphite crucible yakagadzirwa nezvinhu zvechisikigo zvegraphite, izvo zvinochengetedza kupisa kwepakutanga kwakakosha kwemoto wegraphite. Graphite crucible inonyanya kushandiswa pakunyungudutsa simbi dzisina ferrous dzakadai semhangura, aruminiyamu uye alloy. Kune zvinhu zvisingaverengeki zvegraphite crucible pachayo. Pano tichanyora muchidimbu chimwe kana zviviri zvako.
1. Kusvibiswa kushoma, nekuti simba rakachena senge gasi rechisikigo kana gasi rakanyungudutswa rinogona kushandiswa semafuta uye kusvibiswa kushoma.
2. Kushandiswa kwesimba shoma, nekuti girafu ine hurongwa hwakanaka, chimiro chepamusoro uye zvinhu zvitsva. Mushure mekuedza, kushandiswa kwesimba kwakaderera pane kwerudzi rumwe chete rwechoto.
Chitofu chegirafiti chakasimba chinoshandiswa zvakanyanya pakunyungudutsa goridhe, sirivha nesimbi dzisingawanzoonekwi.Zvigadziko zvesimbi zveceramicZvinonyanya kushandiswa mumarabhoritari uye kunyungudutsa platinum, goridhe nesimbi dzisingawanzoonekwi. Chinonyungudika chegrafiti chinogona kushandiswa pakupisa kwakanyanya kwe2000 ℃ kana chiri mumhepo here? Chinoora here uye chinoomesa zvine simba? Chinoomesa simbi yakanyungudutswa here? Chinhu chakakosha ndechekuti carburizing inouraya. Mumamiriro ezvinhu akajairwa, inogona kusvika 2000 degrees mumhepo, asi inoomesa nekukurumidza. Dambudziko recarburizing yesimbi rinofanira kunge riripo. Iye zvino kune coating yakakosha ye anti carburizing pamusika, iyo inonzi ine mhedzisiro yakanaka.
