Mbiri Yachitukuko ya Silicon carbide crucible

Pankhani ya zitsulo, mbiri yopangira Silicon carbide crucible yomwe imagwiritsidwa ntchito posungunula zitsulo zosakhala ndi chitsulo idayambira m'ma 1930. Njira yake yovuta imaphatikizapo kuphwanya zopangira, kugwedeza, kupota dzanja kapena kupanga mpukutu, kuyanika, kuwombera, kupaka mafuta ndi kutsimikizira chinyezi. Zosakaniza zomwe zimagwiritsidwa ntchito zimaphatikizapo graphite, dongo, pyrophyllite clinker kapena high-alumina bauxite clinker, ufa wa monosilica kapena ferrosilicon ufa ndi madzi, osakaniza mu gawo linalake. M'kupita kwa nthawi, silicon carbide yaphatikizidwa kuti ipititse patsogolo matenthedwe matenthedwe ndikuwongolera bwino. Komabe, njira yachikhalidwe iyi imakhala ndi mphamvu zambiri, nthawi yayitali yopanga, komanso kutayika kwakukulu komanso kusinthika mu gawo lomaliza lazinthu.

Mosiyana ndi izi, njira zamakono zopangira ma crucible crucible ndi kukanikiza kwa isostatic. Tekinoloje iyi imagwiritsa ntchito graphite-silicon carbide crucible, yokhala ndi utomoni wa phenolic, phula kapena phula monga chomangira, ndi graphite ndi silicon carbide monga zida zazikulu zopangira. The crucible chifukwa ali otsika porosity, mkulu kachulukidwe, mawonekedwe yunifolomu ndi amphamvu dzimbiri kukana. Ngakhale zabwino izi, kuyaka kumatulutsa utsi woyipa ndi fumbi, zomwe zimawononga chilengedwe.

Kusinthika kwa Silicon carbide crucible kupanga kumawonetsa kufunafuna kwamakampani komwe kukupitilira kuchita bwino, luso komanso udindo wachilengedwe. Pamene ukadaulo ukupita patsogolo, cholinga chake ndikukhazikitsa njira zochepetsera kugwiritsa ntchito mphamvu, kufupikitsa nthawi yopanga komanso kuchepetsa kuwononga chilengedwe. Opanga ma Crucible akuwunika zida ndi njira zatsopano kuti akwaniritse zolingazi, ndicholinga chofuna kuti pakhale mgwirizano pakati pa miyambo ndi zamakono. Pamene kufunikira kosungunula zitsulo kosakhala ndi ferrous kukukulirakulira, chitukuko cha kupanga crucible chidzagwira ntchito yofunika kwambiri pakukonza tsogolo lazitsulo.
