narkewar tanderun jan ƙarfe na graphite crucible yadda za a zaɓa?

Copper narkewa graphite crucible / silicon carbide crucible smelting daban-daban zinariya, azurfa, jan karfe, aluminum, gubar, tutiya da sauran wadanda ba ferrous karafa, matsakaici carbon karfe, daban-daban rare karafa da carbon kayayyakin masana’antu. Ya dace da narkar da ƙarfe a cikin tanderun ƙasa, wutar lantarki, matsakaicin mitar tanderun da manyan murhun wuta.

1. Kyakkyawan juriya mai zafi na narkakken jan ƙarfe graphite crucible, zafin jiki na narkewa zai iya zama kamar kusan 1800 ° C;

2. Kyakkyawan thermal conductivity na graphite crucible ga narkakkar jan karfe yana da karamin thermal fadada coefficient, iya gudanar da zafi da sauri, kuma yana da karfi iri juriya ga sauri dumama da quenching;

3. Kyakkyawan kwanciyar hankali na sinadarai na crucible na musamman don narkewar jan ƙarfe yana da ƙarfin juriya ga acid da alkaline mafita.
