I ka wā o ke kaʻina hana i kēlā me kēia lā, ma muli o ka ʻelemakule o ka umu sintering, nitrogen generator, ammonia decomposition a me nā mea hana ʻē aʻe, nā huahana metallurgy pauka ma hope o ka umu he mau pilikia o ka oxidation e like me ka blackening, yellowing, decarburization, a me ka sandblasting ma ka ʻili. o ka huahana.

Ma hope o ka puka ʻana o ka pilikia, pono ka mea hana e noiʻi i ka lewa pale i ka hiki.Hoʻopili maʻamau nā mea nānā inā hana maʻamau ka mālama mau ʻana o ka mea hana nitrogen, ke kūlana hana o ka mea hana nitrogen, a inā pololei nā waiwai o ka mea hana nitrogen P860 nitrogen analyzer.Inā ʻo ke kaomi hana o ka hale kiaʻi adsorption o ka mea hoʻoheheʻe nitrogen ma lalo o ka laina maʻamau, inā paha ʻo ka deoxygenation wela o ka palladium catalyst i loko o ka hydrogenation a me ka deoxygenation ʻāpana ma waho o ka maʻamau maʻamau, inā paha ka hoʻomaʻemaʻe ʻana a me ka hoʻomaloʻo ʻana i ka hapa maʻamau, a. ʻO ka ʻike o ka oxygen a me ka wai nitrogen ma ka hope o ka hoʻomaʻemaʻe nitrogen he mau hōʻailona inā paha i loko o ka laulā o ka waiwai maʻamau, pono e lawe i kahi pane kūpono i nā pilikia paʻa.

Hoʻohana maʻamau nā huahana metallurgy pauka i ke kāʻei mesh i ka umu annealing hoʻomau a me ka pahu pahu annealing umu no ka sintering.Hoʻokaʻawale ʻia ka lewa pale i nā huahana keleawe a me nā huahana hao e like me nā mea o nā huahana metallurgy pauka.ʻO ka mea maʻamau, paʻi ʻia ka pauka hao e hana i nā huahana sintered loa, a me ka hao-hoʻokumu No nā huahana metallurgy pauda, ​​ʻoi aku ka maʻemaʻe kiʻekiʻe me ka wai ma lalo o 5PPM a me kahi maʻemaʻe kiʻekiʻe 99.999% i hana ʻia e kahi mea hana hydrogen decomposition amonia a i ʻole. Hiki ke hoʻohana ʻia kahi PSA ma ka pūnaewele nitrogen generator a me ka hydrogenation a me ka hoʻomaʻemaʻe deoxygenation ma ke ʻano he lewa pale.Ma hope o kekahi mau pilikia o ka hoʻoheheʻe ʻana i loko o nā huahana metallurgy pauka, e nānā i ka mea maʻamau ka mea hoʻoheheʻe nitrogen a me ka umu hoʻoheheʻe ammonia, a i ʻole ma hope o ka hoʻoponopono ʻana i ka mea hoʻoheheʻe nitrogen a me ka decomposition amonia, e mau ana ka pilikia oxidation o nā huahana metallurgy pauda.

ʻO ka hana aʻe e noʻonoʻo i ka umu sintering pono'ī.

Inā he kapuahi pahu pahu a i ʻole he umu kāʻei mesh, aia kahi wahi hoʻoluʻu wai.Ma hope o ka ʻelemakule ʻana o ka pahu muffle o ka umu sintering, e kahe ka wai.E hoʻoheheʻe ʻia ka wai i oxygen i ka wela kiʻekiʻe, e lilo ai nā huahana metallurgy pauda i ʻeleʻele a melemele a decarbonize.ʻO Ding Wentao, inā ʻo Burn ma nā wela kiʻekiʻe a me nā lapalapa.Hoʻokumu ʻia ke ahi ma muli o ka puhi ʻana o ka hydrogen a me ka pauka metallurgical i loko o ka umu sintering.I kēia manawa, e hoʻopuka ʻia nā mea sandblasted ma luna o ka ʻili o ka huahana, ʻo ia nā koena kuni.Inā hoʻohana ʻia kahi uhi pale e uhi iā ia, e hoʻomaikaʻi ʻia, akā ʻaʻole i hoʻopaʻa ʻia ka pale ʻana o ka nitrogen maʻemaʻe kiʻekiʻe.

Eia nō naʻe, no nā huahana metallurgy pauka keleawe maʻemaʻe, ʻo ka 75% hydrogen + 25% nitrogen hui pū ʻia i hana ʻia e ka ammonia decomposition e hana i ka hydrogen hiki ke hoʻohana ʻia i ka lewa pale.ʻOiaʻiʻo, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka hydrogen maʻemaʻe kiʻekiʻe, ma muli o ke kumukūʻai kinoea nui a me ka palekana hana.Hoʻohana ka hapa nui o lākou i nā mea hana hydrogen decomposition hydrogen i kumu o ka hydrogen.

I ka wā e kahe ai ka pahu muffle o ka umu sintering a ʻā, e hoʻōki koke ka hana ʻana o ka ʻōpala muffle a hoʻololi.I ʻole e hoʻopilikia i ka maikaʻi o ka huahana!
