macrucibles anogadzirwa nei?

The composition ofcruciblezvinhu uye kukosha kwavo mune metallurgy

Crucible chishandiso chakakosha muindasitiri yemetallurgical, inoshandiswa kuve nekupisa simbi dzakasiyana siyana uye alloys. Nekudaro, kuumbwa kwezvinhu zvecrucible kunokanganisa zvakananga kuita kwayo uye hupenyu munzvimbo dzekushisa kwepamusoro. Naizvozvo, kunzwisisa kuumbwa kweiyo crucible zvinhu kwakakosha pakusarudza iyo chaiyo crucible ye metallurgical application. Ichi chinyorwa chichaongorora zvakakosha zvezvinhu zve crucibles uye kukosha kwavo mumetallurgical application.

1.Graphite crucible
Graphite crucible ndeimwe yemhando dzakajairika. Nekuda kwekunaka kwayo kwepamusoro tembiricha kuramba uye kugadzikana kwemakemikari, inoshandiswa zvakanyanya mukunyungudutsa simbi dzisina-ferrous sealuminium, mhangura, negoridhe. Chinhu chikuru che graphite crucible is carbon, iyo ine yakanakisa yekupisa conductivity, inobvumira simbi kupisa nekukurumidza uye zvakaenzana, nekudaro ichideredza nguva yekunyungudika. Mukuwedzera, graphite crucible ine yakanaka corrosion resistance uye inogona kumira nekukukurwa kwezvinhu zvakawanda zvine acidic uye alkaline yakanyungudutswa.

2.Silicon carbide crucible
Silicon carbide crucibles inofarirwa neiyo metallurgical indasitiri nekuda kwekuoma kwavo kwakanyanya uye oxidation kuramba. Silicon carbide chinhu chakanyanya kuoma icho chinogona kumira zvakanyanya tembiricha pasina kukanganisa. Zvichienzaniswa ne graphite crucibles, silicon carbide crucibles ine hupenyu hurefu hwebasa uye inonyanya kukodzera kunyunguduka kwesimbi, simbi uye mamwe masimbi ekupisa. Uye zvakare, iyo silicon carbide zvinhu ine yakanaka yekupisa kugadzikana kugadzikana, ichidzikisa njodzi yekukuvara kune crucible nekuda kwekukurumidza kuchinja kwekushisa.

3. Ceramic crucible
Ceramic crucibles inonyanya kugadzirwa neceramic zvinhu senge alumina uye zirconia. Aya macrucibles anoratidza yakanakisa kemikari inertness uye akakodzera kugadzirisa simbi uye alloys ayo anoparadza zvakanyanya kune zvimwe zvinhu. Iyo yakakwira yekunyungudika yeceramic crucibles inovagonesa kuramba yakagadzikana pasi peyakanyanya-yepamusoro tembiricha mamiriro uye inoshandiswa zvakanyanya mumarabhoritari uye mamwe akakosha maindasitiri ekushandisa. Nekudaro, ma crucibles eceramic ane brittle uye anoda kungwarira kubata panguva yekushandiswa kudzivirira kutyoka nekuda kwekukanganisa kwemuchina.

4. Steel crucible
Simbi macrucibles anowanzo shandiswa muhombe yekunyungudutsa simbi, senge foundries. Simbi macrucibles anowanzo gadzirwa neasingapi kupisa simbi alloys uye ane yakanakisa mechanicha simba uye yakakwirira tembiricha kuramba. Kunyangwe ma crucibles esimbi asina kutonhora senge graphite crucibles, anogona kumirisana nekukatyamadzwa kwemuviri, zvichiita kuti akwanise kunyungudusa mabasa anoda kugara achirodha uye kuburutsa kana kutamiswa.

5. Zvimwe zvinhu
Pamusoro pezvakajairwa crucible zvinhu zvataurwa pamusoro apa, kune zvakare zvimwe zvehunyanzvi zvekushandisa zvinoshandisirwa zvinangwa chaizvo. Semuyenzaniso, tungsten crucibles anowanzo shandiswa mukukwira-tembiricha kuyedza nekuda kweiyo yakanyanya kunyungudika nzvimbo yekunyungudika uye kushora. Titanium crucibles inoshandiswa kunyungudutsa specialty alloys nekuti haibatike nesimbi zhinji.

Mukupedzisa
Iko kuumbwa kwezvinhu zvecrucible hakungotaridzi kugadzikana kwayo uye kusimba munzvimbo dzekushisa kwepamusoro, asiwo zvinokanganisa zvakananga kushanda uye kuchengetedzwa kwemaitiro ekunyungudika. Naizvozvo, kana uchisarudza crucible, zvinhu zvemakemikari zvimiro, yekupisa conductivity, simba remakanika uye hupenyu hwesevhisi hunofanirwa kutariswa zvichienderana nezvinodiwa zvekushandisa. Crucibles yemhando dzakasiyana-siyana inoita basa risingadzokerike muindasitiri yesimbi, ichipa vimbiso yakavimbika yekushanda uye yakachengeteka simbi kugadzirisa.
