Ka hoʻomaopopo ʻana i nā palena o ka Clay Graphite Crucibles i ka Induction Heating

Hoʻolauna:Pālolo graphite cruciblesHe kuleana koʻikoʻi ia i nā kaʻina hana metallurgical, akā ʻo ko lākou kūlike me ka hoʻomehana induction he kumuhana o ka nīnau. Ke manaʻo nei kēia ʻatikala e wehewehe i nā kumu ma hope o ka hiki ʻole o nā crucibles graphite pālolo e hoʻokō pono i ka hoʻomehana induction, e hāʻawi ana i nā ʻike i ka ʻepekema ma hope o kēia mau palena.

Ka Hoʻohui a me ke kuleana o ka pālolo graphite crucibles: hoʻohana mau ʻia nā crucibles graphite pālolo i nā noi wela kiʻekiʻe ma muli o kā lākou haku mele ʻana, ʻo ia hoʻi ka pālolo a me ka graphite. ʻO kēia mau crucibles he mau ipu no ka hoʻoheheʻe ʻana a me ka hoʻolei ʻana i nā metala, e hāʻawi ana i ka conductivity thermal maikaʻi loa a me ke kū ʻana i ka haʻalulu wela.

Nā Luʻi i ka Induction Heating: ʻOiai ko lākou mau waiwai maikaʻi, ke kū nei nā crucibles graphite pālolo i nā pilikia i ka wā e hoʻokau ʻia ai nā kaʻina hoʻomehana induction. Ke hilinaʻi nei ka hoʻomehana induction i ka induction electromagnetic, kahi e hoʻoulu ai kahi māla magnetic i nā au eddy i loko o ka mea, e hana ana i ka wela. ʻO ka mea pōʻino, ʻo ka haku ʻana o nā crucibles graphite pālolo ke keʻakeʻa nei lākou i kā lākou pane ʻana i kēia mau māla magnetic.

1. ʻAʻole hoʻokō maikaʻi ʻia i nā kahua Electromagnetic. ʻO ka hoʻomehana hoʻoulu ʻana e hilinaʻi nui ʻia i ka hiki o ka mea hana ke hoʻoulu i nā au eddy, a ʻo ka haʻahaʻa haʻahaʻa o ka pālolo graphite e kaupalena ʻia kona pane ʻana i ke kaʻina hana induction.

2. Ka palena o ka Permeability i ka Magnetic Fields: ʻO kekahi kumu ʻē aʻe e kōkua ana i ka maikaʻi ʻole o ka pālolo graphite crucibles i ka hoʻomehana induction ʻo ko lākou palena permeability i nā māla magnetic. ʻO ka maʻiʻo pālolo i loko o ka crucible e hoʻopau i ke komo like ʻana o ke kahua magnetic, ka hopena i ka wela ʻole a me ka hoʻemi ʻana i ka ikehu.

3. Nā Pohō ma muli o ka maʻiʻo Graphite: ʻOiai ʻike ʻia ka graphite no kāna conductivity uila, ʻo ke ʻano hui o nā crucibles graphite pālolo e alakaʻi i nā poho o ka hoʻoili ikehu. ʻAʻole hiki i nā ʻāpana graphite i hoʻopuehu ʻia i loko o ka pālolo matrix ke kūpono ʻole me ke kahua magnetic, e alakaʻi ana i ka nalowale o ka ikehu ma ke ʻano o ka wela i loko o ka mea crucible ponoʻī.

ʻO nā mea hana ʻē aʻe no ka hoʻomehana ʻana: ʻo ka hoʻomaopopo ʻana i nā palena o ka pālolo graphite crucibles e koi ai i ka ʻimi ʻana i nā mea ʻē aʻe i kūpono no ka hoʻomehana induction. ʻO nā crucibles i hana ʻia mai nā mea me ka conductivity uila kiʻekiʻe, e like me ka silicon carbide a i ʻole kekahi mau metala refractory, makemake ʻia no nā noi e koi ana i ka hoʻomehana induction kūpono.

Panina: Ma ka hōʻuluʻulu manaʻo, ʻo ka hiki ʻole o ka pālolo graphite crucibles e hana i ka hoʻomehana induction maikaʻi e ala mai i ko lākou conductivity maikaʻi ʻole i nā kahua electromagnetic, ka palena permeability i nā māla magnetic, a me nā poho e pili ana i ka maʻiʻo graphite. ʻOiai ʻoi aku ka maikaʻi o nā crucibles graphite pālolo ma nā noi metallurgical he nui, ʻoi aku ka maikaʻi o nā mea ʻē aʻe inā he mea koʻikoʻi ka hoʻomehana induction. ʻO ka ʻike ʻana i kēia mau palena e kōkua i ka hana ʻana i nā koho ʻike no ke koho crucible maikaʻi loa i nā kaʻina hana ʻenehana like ʻole.
