No ke kila hoʻolei a i ʻole ʻoihana foundry o ka umu hoʻoheheʻe uila, ka hoʻohana ʻana i ka sulfur haʻahaʻa, haʻahaʻa nitrogen, kiʻekiʻe absorption rate carburizer ke kumu o ka ʻenehana carburizing.
ʻO ka graphitized petroleum coke recarburizer nā wahi hana nui o Liaoning, Tianjin, Shandong a pēlā aku.
Liaohe oilfield mea ka hana wahi o ka haʻahaʻa sulfur crude aila i loko o ka honua, a graphitized petroleum coke i ka haʻahaʻa sulfur a me naikokene maʻiʻo.
He mea nui ka porosity o ka recarburizer i ka hopena o ka recarburizer a me ka helu absorption o ka recarburizer.
Ma o ke kaʻina hana, ua wehe ʻia nā pores o ka aila coke recarburizer, i hoʻonui ʻia ka ʻāpana kikoʻī o ka recarburizer, ʻoi aku ka maikaʻi o ka huahana, hiki ke hoʻoheheʻe koke ʻia i ke kila hoʻoheheʻe, i mea e hoʻonui ai i ka helu absorption a ka hana carburizing.
E like me nā hoʻohana like ʻole o ka recarburizer, nā ʻano maka like ʻole, he nui nā ʻano mea maka a me nā kaʻina hana like ʻole, e like me ke kalapona lāʻau, carbon carbon, coke, graphite, etc., he nui nā ʻano liʻiliʻi, he ʻano ākea.
ʻO ka mea hana carburizing kiʻekiʻe e pili ana i ka graphitization carburizing agent.
Hoʻonohonoho ʻia ka hoʻonohonoho ʻana o nā ʻātoma kalapona i ka wela kiʻekiʻe ma ke ʻano microscopic o ka graphite, no laila ua kapa ʻia ʻo graphitization.
Hiki i ka graphitization ke hōʻemi i ka ʻike o nā mea haumia i ka carburizing agent, hoʻonui i ka ʻike kalapona o ka carburizing agent, hoʻemi i ka ʻike sulfur.
ʻO ka hoʻohana ʻana i nā mea carburizing i ka hoʻoheheʻe ʻana hiki ke hoʻonui nui i ka nui o ka ʻōpala, hoʻemi i ka nui o ka hao puaʻa a ʻaʻole hoʻohana i ka hao puaʻa.
I ka uila umu hooheheeia o ka hanai ala, pono e hui carburizer a me ka hao hao a me na mea e ae, a hiki ke koho i ka liʻiliʻi doses i hoʻohuiʻia i ka ili o ka hao hooheheeia, akā, e pale aku i ka nui helu o ka ai i loko o ka hao hehee ai, i mea e pale aku excessive. oxidation, kalapona maʻiʻo o castings, hoolei kalapona maʻiʻo 'aʻole maopopo, e like me ka lākiō o kekahi maka mea a me kalapona maʻiʻo e hoʻoholo i ka nui o ka recarburizer.
ʻO nāʻano likeʻole o ka hao hao, e like me ka pono e koho i nāʻano likeʻole o ka recarburizer.
ʻO nā hiʻohiʻona o ka recarburizer pono'ī ke koho o nā mea graphitized maʻemaʻe i loaʻa i ke kalapona, i mea e hōʻemi ai i nā haumia nui i ka hao puaʻa, hiki i ke koho kūpono o ka recarburizer ke hōʻemi i ke kumukūʻai hana o nā castings.
He kūpono ka carburizing agent no ka hoʻoheheʻe ʻana i ka umu induction, akā ʻokoʻa kona hoʻohana kikoʻī e like me nā koi ʻenehana.
ʻO ka carburizing agent i hoʻohana ʻia i ka hoʻoheheʻe ʻana i ka umu uila hiki ke hoʻohui ʻia i ka waena a me ka hapa haʻahaʻa o ka umu uila e like me ka ratio a i ʻole carbon equivalent koi, a hiki i ka helu hoʻihoʻi ke piʻi aku ma mua o 95%.
Inā ʻaʻole lawa ka nui o ke kalapona e hoʻoponopono ai i ka ʻike kalapona, e hoʻomaʻemaʻe mua i ka slag i loko o ka umu, a laila e hoʻohui i ka carburizer, ma ka hoʻomehana ʻana i ka hao i hoʻoheheʻe ʻia, ka hoʻoulu ʻana electromagnetic a i ʻole ka hoʻoulu ʻana e hoʻoheheʻe a hoʻopaʻa i ke kalapona, hiki i ka helu hoʻihoʻi ke hiki ma kahi o 90 %.
Inā hoʻohana ʻia ke kaʻina hana recarburizer haʻahaʻa, ʻo ia hoʻi, hoʻoheheʻe ka uku i kahi hapa o ka hao i hoʻoheheʻe ʻia, a ʻoi aku ka haʻahaʻa o ka hao i hoʻoheheʻe ʻia, e hoʻohui ʻia ka recarburizer a pau i ka hao i hoʻoheheʻe ʻia i ka manawa like, ʻoiai ka uku paʻa. e kaomi i loko o ka hao i hooheheeia, i mea e pale aku ai i kona ike ana i ka ili o ka hao hehee.
Ma kēia ʻano, hiki i ka carburization o ka hao hoʻoheheʻe ʻia ke piʻi aku ma mua o 1.0%.
Hiki ke hoʻohana ʻia ka Petroleum coke recarburizer no ka hoʻolei ʻana i ka hao hina hina.
He kalapona ka haku mele: 96-99%;
S0.3-0.7%.
Hoʻohana nui ʻia i ka hana kila, ka hao hina hina, nā pad brake, cored wire, etc.
Henan Liugong Graphite Co., Ltd., calcined aila coke recarburizer graphitization recarburizer mea hana, e hoolauna aku oe calcined aila coke ua calcined aila coke recarburizer, ke kumu mea nui e wehe i na haumia, a calcined aila coke recarburizer graphitization i loko o ka graphitization. , wai a me nā mea hoʻoheheʻe.
