Mumunda wesimbi, nhoroondo yekugadzira yeSilicon carbide crucible inoshandiswa kunyungudutsa simbi dzisina-ferrous inogona kurondwa kumashure kuma1930s. Maitiro ayo akaomarara anosanganisira mbishi kupwanya, batching, ruoko kuruka kana roll kuumba, kuomesa, kupfura, oiri uye hunyoro-proofing. Zvinhu zvinoshandiswa zvinosanganisira graphite, ivhu, pyrophyllite clinker kana high-alumina bauxite clinker, monosilica powder kana ferrosilicon powder nemvura, yakasanganiswa mune imwe chikamu. Nekufamba kwenguva, silicon carbide yakaiswa kuti iwedzere kupisa conductivity uye kunatsiridza mhando. Nekudaro, iyi yechinyakare nzira ine yakakwira simba rekushandisa, kutenderera kwenguva refu yekugadzira, uye kurasikirwa kukuru uye deformation muhafu-yakapedza chigadzirwa nhanho.
Kusiyana neizvi, yanhasi yakanyanya kusimukira crucible forming process is isostatic pressing. Iyi tekinoroji inoshandisa graphite-silicon carbide crucible, ine phenolic resin, tara kana asphalt seanosunga mumiriri, uye graphite nesilicon carbide seyakanyanya mbishi zvinhu. Iyo inokonzeresa crucible ine yakaderera porosity, yakakwira density, yunifomu magadzirirwo uye yakasimba corrosion kuramba. Pasinei nezvakanakira izvi, nzira yekupisa inoburitsa utsi hunokuvadza neguruva, zvichikonzera kusvibiswa kwezvakatipoteredza.
Iko kushanduka kweSilicon carbide crucible kugadzirwa kunoratidza kuenderera mberi kweindasitiri kutsvaga kwekuita, kunaka uye basa rezvakatipoteredza. Sezvo tekinoroji ichifambira mberi, chakatarisana nekugadzira nzira dzekudzikisa kushandiswa kwesimba, kupfupisa kutenderera kwekugadzira uye kudzikisira kukanganisa kwezvakatipoteredza. Vagadziri veCrucible vari kuongorora zvinhu zvitsva uye maitiro ekuzadzisa izvi zvinangwa, vachivavarira kurova chiyero pakati pechinyakare uye chazvino. Sezvo kudiwa kweiyo isiri-ferrous simbi kunyungudutsa kuri kuramba kuchikura, kusimukira mukugadzirwa kwecrucible kuchaita basa rakakosha mukuumba ramangwana resimbi.
