E like me nā ʻano hoʻoheheʻe like ʻole, ʻano umu ahi a me ka nui o ka umu hoʻoheheʻe, he mea nui hoʻi e koho i ka nui o ka carburizer particle nui, hiki ke hoʻomaikaʻi maikaʻi i ka helu absorption a me ka absorption rate o ka wai hao i ka carburizer, e pale i ka oxidation a me ka pau ʻana o ka carburizer i kumu. ma ka liʻiliʻi liʻiliʻi.
ʻOi aku ka maikaʻi o kona nui: 100kg ka umu ma lalo o 10mm, 500kg ka umu ma lalo o 15mm, 1.5 ton umu ma lalo o 20mm, 20 ton umu ma lalo o 30mm. ʻO ka hoʻoheheʻe ʻana o ka mīkini hoʻololi, ke kila kalapona kiʻekiʻe, ka hoʻohana ʻana i nā mea haumia liʻiliʻi i loko o ka mea hana kalapona. Ke koi o ka carburizer no ka top-blown (rotary) mīkini hoʻololi steelmaking he kiʻekiʻe paʻa kalapona, haʻahaʻa maʻiʻo o ka lehu, volatilization, sulfur, phosphorus, nitrogen a me nā mea haumia'ē aʻe, a me ka maloʻo, maʻemaʻe, moderate particle size.Its paʻa kalapona C≥96% , volatiles ≤1.0%, S≤0.5%, moisture ≤0.5%, ka nui o nā mea i loko o 1-5mm. Inā ʻoi aku ka liʻiliʻi o ka nui o ka ʻāpana, e ʻā koke ia. Inā mānoanoa loa ka nui o ka ʻāpana, e lana ana ia ma ka ʻili o ke kila hoʻoheheʻe a ʻaʻole hiki ke komo maʻalahi e ke kila hoʻoheheʻe. ʻO ka nui o ka nui o ka umu induction he 0.2-6mm, ma waena o ka nui o ke kila a me nā metala ferrous ʻē aʻe he 1.4-9.5mm, ʻo ke kila kalapona kiʻekiʻe e koi ai i ka nitrogen haʻahaʻa, a ʻo ka nui o ka nui he 0.5-5mm, etc. pono e hana ʻia e like me ke ʻano kikoʻī o ka mea hana hoʻoheheʻe ʻana o ka umu ahi a me nā kikoʻī ʻē aʻe.
