Kaʻina hana Recarburizer a me nā mea maka

He mea kalapona ka recarburizer.Hoʻohui ʻia nā Carburizers i ka wā o ka hoʻoheheʻe ʻana e hoʻohui i ka ʻike kalapona i nalowale i ka wā o ka hoʻoheheʻe kila.Ua ʻike mākou he nui nā ʻano recarburizers, e like me ka petroleum coke recarburizers, artificial graphite recarburizers, a me nā mea ʻē aʻe, no laila ʻokoʻa nā mea maka i koi ʻia no ka recarburizers, no laila he aha nā mea maka o ka recarburizers?ʻO ke kaʻina hana o recarburizers he aha?E haʻi aku ʻo Xiaobian iā ʻoe e pili ana i nā mea maka a me nā kaʻina hana e pono ai no ka recarburizer.

Pono nā mea maka no ka recarburizers
Nui nā ʻano mea maka no ka recarburizers, ʻo ia hoʻi ka lanahu, carbon-based carbon, coke, graphite, petroleum coke, etc.

I kēia manawa, ʻo ka hapa nui o nā recarburizers ma ka mākeke, me nā electrodes graphite, graphitized petroleum coke, etc., hoʻohana i ka coke petroleum maka.Loaʻa ʻia ka coke petroleum crude ma ka coking o ke koena aila a me ka petroleum pitch i loaʻa ma ka distillation o ka ʻaila ʻaila ma lalo o ke kaomi lewa a i ʻole ka ʻūhā.He kiʻekiʻe ka haumia o ka coke petroleum maka a ʻaʻole hiki ke hoʻohana pololei ʻia ma ke ʻano he recarburizer.Pono e calcined a graphitized paha.Pono nā recarburizers kiʻekiʻe i ka graphitization.Ma lalo o nā kūlana wela kiʻekiʻe, ʻo ka hoʻonohonoho ʻana o nā ʻātoma kalapona ma ke ʻano microscopic o ka graphite, no laila ua kapa ʻia ʻo graphitization.Hiki i ka graphitization ke ho'ēmi i ka maʻiʻo o ka haumia i loko o ka recarburizer, hoʻonui i ke kalapona o ka recarburizer, a ho'ēmi i ka sulfur maʻiʻo.Hoʻohana ʻia nā recarburizers no ka hoʻolei ʻana, hiki ke hoʻonui nui i ka nui o ka hao hao, hoʻemi i ka nui o ka hao puaʻa a i ʻole e mālama i ka hao puaʻa.

Kaʻina Carburizer
Ma muli o ka nui o nā mea maka no ka recarburizers, ʻokoʻa nā kaʻina hana, akā aia ka nui o nā mea ʻekolu:

1. Hoʻokalakala
Hoʻopili ʻia nā mea maka carbonaceous ma kahi wela kiʻekiʻe o 1200-1500 ° C me ka ʻole o ka ea.Hoʻololi ka hoʻololi ʻana i ka hana a me nā waiwai physicochemical o nā mea maka.ʻO ia ke kaʻina hana wela o ka recarburizer.Loaʻa i ka anthracite a me ka petroleum coke kekahi mau mea volatile a koi aku i ka calcination.Eia naʻe, i ka hui ʻana o ka petroleum coke a me ka pitch coke a hoʻohana ʻia ma mua o ka calcination, pono e hoʻouna ʻia i ka calciner no ka calcination me ka petroleum coke.

2. Kaʻana ʻana
ʻO ka hoʻomoʻa ʻana he hana hoʻomaʻamaʻa wela kahi i hoʻomoʻa ʻia ai ka meaʻai maka i kaomi ʻia ma kahi ʻano wela i loko o ka mea pale i loko o ka umu wela ma lalo o ke ʻano o ka ea hoʻokaʻawale.
ʻO ke kumu o ka ʻala ʻana, ʻo ia ka hoʻopau ʻana i nā volatiles.ʻO ka maʻamau, ma kahi o 10 mau ʻano volatiles e hoʻokuʻu ʻia ma hope o ka ʻala ʻana.No laila, he 90 ka nui o ka loaʻa ʻana o ka palaoa;ua coked ka mea hoʻopaʻa, a ua ʻai ʻia ka huahana e like me kekahi mau kaʻina hana, no laila ua coked ka mea hoʻopaʻa, a ua hoʻokumu ʻia kahi pūnaewele coke ma waena o nā ʻāpana maka, kahi e hoʻopili paʻa ai i nā mea maka a pau me nā ʻāpana like ʻole.E hana i nā huahana # # i kekahi mau waiwai kino a me kemika.Ma lalo o nā kūlana like, ʻoi aku ka kiʻekiʻe o ka coking rate, ʻoi aku ka maikaʻi o ka maikaʻi;i ka hihia o ka geometry paʻa, e palupalu ka huahana a neʻe ka mea hoʻopaʻa i ka wā o ka hana ʻana.Ke piʻi aʻe ka mahana, hoʻokumu ʻia kahi pūnaewele coking, kahi e paʻakikī ai ka huahana.No laila, ʻaʻole loli kona ʻano i ka piʻi ʻana o ka mahana.

3. Extrusion
ʻO ke kumu o ke kaʻina hana extrusion ʻo ia ka hana ʻana i ka mea maka i loko o kahi ʻano o kekahi ʻano ma lalo o ke kaomi, a lilo i billet me kahi ʻano a me ka nui ma hope o ka hoʻopili ʻana a me ka plastically deformed.ʻO ke kaʻina hana hoʻoheheʻe extrusion ka nui o ke kaʻina deformation plastic o ka paʻi.Hana ʻia ke kaʻina extrusion i loko o kahi keʻena waiwai a me kahi nozzle curved.Hoʻokuʻu ʻia ka mea wela i loko o ke keʻena e ka plunger nui ma hope.Ke hoʻoneʻe mau ʻia o ke kinoea mai ka mea maka, ka hoʻopili mau ʻana o ka mea maka, a me ka neʻe like ʻana o ka mea maka i mua.Ke neʻe ka mea maka i loko o ka ʻāpana cylindrical o ke keʻena waiwai, hiki ke ʻike ʻia ka mea maka ma ke ʻano he kahe paʻa, a ʻo kēlā me kēia ʻāpana ʻāpana ke neʻe like.Ke komo ka mea maka i loko o ka nozzle extrusion a loaʻa ka deformation arc-like, ʻo ka mea maka kokoke i ka paia nozzle e ʻike i ke kūʻē frictional ʻoi aku ka nui o ka neʻe ʻana, a hoʻomaka ka ʻili o ka mea e piko.ʻOkoʻa ka wikiwiki o ka holomua ʻana o ka mea maka, a me ka holomua o ka mea maka i loko.No laila, ʻaʻole like ka mānoanoa o ka huahana ma ka ʻaoʻao radial, no laila e hoʻoulu ai i ke koʻikoʻi kūloko i hoʻokumu ʻia e nā kahe kahe like ʻole o nā papa o loko a me waho o ka poloka extruded.Ma hope o ka hoʻokomo ʻana o ka paʻi i ka ʻāpana deformation pololei, ua extruded a hana ʻia.
Pono ke ʻano extrusion e hoʻohui i ka binder no ka hoʻoheheʻe ʻana, a ʻaʻole kūpono ka ʻike kalapona i nā koi o nā recarburizers kiʻekiʻe.Compressed graphite pauda, ​​no ka mea, he paʻa poloka, ʻaʻohe hale porous, no laila ʻaʻole maikaʻi ka wikiwiki o ka absorption a me ka absorption e like me ka calcined a me ka calcined recarburizers.
