ʻO ka Moʻolelo Hoʻomohala o Silicon carbide crucible

Ma ke kahua o ka metallurgy, hiki ke huli ʻia ka mōʻaukala hana o Silicon carbide crucible i hoʻohana ʻia no ka hoʻoheheʻe ʻana i nā metala non-ferrous i ka makahiki 1930. ʻO kāna kaʻina hana paʻakikī e pili ana i ka ʻoki ʻana i nā mea maka, ka hui ʻana, ka wili lima a i ʻole ka ʻōwili ʻana, ka hoʻomaloʻo ʻana, ke kī ʻana, ka ʻaila a me ka hoʻomaʻamaʻa. ʻO nā mea i hoʻohana ʻia he graphite, pālolo, pyrophyllite clinker a i ʻole kiʻekiʻe-alumina bauxite clinker, pauka monosilica a i ʻole ferrosilicon pauka a me ka wai, i hui pū ʻia i kekahi ʻāpana. I ka wā lōʻihi, ua hoʻohui ʻia ka silicon carbide e hoʻomaikaʻi i ka conductivity thermal a hoʻomaikaʻi i ka maikaʻi. Eia nō naʻe, ʻo kēia ʻano hana kuʻuna he kiʻekiʻe ka hoʻohana ʻana i ka ikehu, ka lōʻihi o ka hana ʻana, a me ka poho nui a me ka deformation i ka pae huahana semi-finished.

ʻO ka ʻokoʻa, ʻo ke kaʻina hana crucible kiʻekiʻe loa o kēia lā ʻo ke kaomi isostatic. Ke hoʻohana nei kēia ʻenehana i ka graphite-silicon carbide crucible, me ka resin phenolic, tar a i ʻole asphalt e like me ka mea hoʻopaʻa paʻa, a me ka graphite a me ka silicon carbide ma ke ʻano kumu kumu. ʻO ka crucible hopena he porosity haʻahaʻa, kiʻekiʻe kiʻekiʻe, ʻano like ʻole a me ke kūpaʻa corrosion ikaika. ʻOiai kēia mau mea maikaʻi, hoʻokuʻu ke kaʻina puhi ahi i ka uahi a me ka lepo, e hoʻohaumia ai i ke kaiapuni.

Hōʻike ka hoʻomohala ʻana o Silicon carbide crucible production i ka ʻimi mau ʻana o ka ʻoihana i ka pono, ka maikaʻi a me ke kuleana kaiapuni. Ke holomua nei ka ʻenehana, aia ka manaʻo i ka hoʻomohala ʻana i nā ala e hōʻemi ai i ka hoʻohana ʻana i ka ikehu, e hoʻopōkole i nā pōʻai hana a hoʻēmi i ka hopena o ke kaiapuni. Ke ʻimi nei nā mea hana Crucible i nā mea hou a me nā kaʻina hana e hoʻokō ai i kēia mau pahuhopu, me ka manaʻo e hoʻopaʻa i ke kaulike ma waena o ka kuʻuna a me ka wā hou. Ke hoʻomau nei ka noi no ka hoʻoheheʻe metala non-ferrous, ʻo ka hoʻomohala ʻana i ka hana crucible e hana nui i ka hana ʻana i ka wā e hiki mai ana o ka metallurgy.
