UHP 450mm Graphite Electrode
He kuleana koʻikoʻi ka graphite electrodes i ka ʻoihana hana kila, hoʻohana pinepine ʻia lākou e hoʻoheheʻe i ka ʻōpala i loko o nā kapuahi uila (i hoʻopau ʻia ʻo EAF). Aia kekahi mau waiwai nui e hoʻoholo ai i ka maikaʻi o ka electrode, he aha lākou?
ʻO ke koena o ka hoʻonui wela
(hoʻopau ʻia ʻo CTE) e pili ana i ke ana o ke ana o ka hoʻonui ʻia ʻana o kahi mea ma hope o ka hoʻomehana ʻia, i ka piʻi ʻana o ka mahana ma 1 ° C, hoʻoulu ia i ka degere hoʻonui o ka laʻana mea paʻa i kahi kuhikuhi kikoʻī, i kapa ʻia ʻo ka hoʻonui laina. coefficient ma ia aoao me ka wae 1×10-6/℃. Inā ʻaʻole i hōʻike ʻia, pili ka helu hoʻonui wela i ka hoʻonui laina laina. ʻO ka CTE o ka graphite electrode e pili ana i ka axial thermal expansion coefficient.
ʻO ka mānoanoa nui
ʻo ia ka ratio o ka nuipaʻa o ka electrode graphite i kona leo, ʻo ka ʻāpana g / cm3. ʻO ka nui o ka puʻupuʻu puʻupuʻu, ʻoi aku ka denser o ka electrode. ʻO ka ʻōlelo maʻamau, ʻoi aku ka nui o ka nui o ka nui o ke ʻano electrode like, ʻoi aku ka haʻahaʻa o ka resistivity uila.
Modulus elastic
He ʻano koʻikoʻi ia o nā waiwai mechanical, a he kuhikuhi ia e ana i ka hiki ke hoʻololi elastic o kahi mea. ʻO Gpa kona ʻāpana. ʻO ka ʻōlelo maʻalahi, ʻoi aku ka nui o ka modulus elastic, ʻoi aku ka palupalu o ka mea, a me ka liʻiliʻi o ka modulus elastic, ʻoi aku ka palupalu o ka mea.
ʻO ke kiʻekiʻe o ka modulus elastic he kuleana piha i ka hoʻohana ʻana i nā electrodes. ʻOi aku ka kiʻekiʻe o ka nui o ka leo o ka huahana, ʻoi aku ka ʻoi aku o ka elastic modulus, akā ʻoi aku ka maikaʻi o ke kūpaʻa haʻalulu wela o ka huahana, a ʻoi aku ka maʻalahi o ka hana ʻana i nā māwae.
