Carburizers ua maheleia i: aila coke carburizers, graphitized carburizers, maoli graphite carburizers, metallurgical coke carburizers, calcined lanahu carburizers, maoli graphite carburizers, a composite mea carburizers.

ʻO nā ʻokoʻa nui ma waena o nā recarburizers graphite a me nā recarburizers lanahu:

1. Heʻokoʻa nā mea maka.Hoʻopili ʻia ka graphite recarburizer ma ka kānana ʻana i ka graphite kūlohelohe, ʻoiai ua calcined ʻia ka recarburizer mai ka anthracite;

ʻO ka lua, ʻokoʻa nā ʻano.Loaʻa i ka Graphite recarburizer nā mea maikaʻi o ka sulfur haʻahaʻa a me ka nitrogen, ke kūpaʻa kiʻekiʻe o ka mahana, ka conductivity uila maikaʻi, a me nā mea ʻē aʻe, ʻaʻole i loaʻa i nā recarburizers ma muli o ka lanahu;

ʻEkolu, ʻokoʻa ka helu absorption.Hiki i ka absorption rate o ka graphite recarburizer ke piʻi aku ma mua o 90%, no laila inā ʻaʻole kiʻekiʻe ke kiʻekiʻe o ka carbon content o ka graphite recarburizer, hiki ke hoʻokō i nā koi o ka hoʻohana;

ʻO ka hā, ʻokoʻa ke kumukūʻai.ʻOiai ke kiʻekiʻe o ke kumukūʻai o ka graphite recarburizer, ʻoi aku ka haʻahaʻa o ke kumukūʻai hoʻohana piha.

Lawe ʻia ka carburization o ka carburizer e ka hoʻoheheʻe ʻana a me ka hoʻopuehu ʻana o ke kalapona i loko o ka hao i hoʻoheheʻe ʻia.Ua hōʻike ʻia nā haʻawina i ka wā o 2.1% ka nui o ke kalapona o ka hao-carbon alloy, hana like nā graphite recarburizers a me non-graphite recarburizers ma muli o ka pulu kino;akā, inā ʻoi aku ka nui o ke kalapona o ka hao i hoʻoheheʻe ʻia ma mua o 2.1%., Hiki ke ho'ohehe'e 'ia ka graphite i loko o ka graphite recarburizer i loko o ka hao ho'ohehe'e, a hiki ke kapa 'ia kēia 'ano he ho'ohehe'e pololei.ʻAʻole hiki ke loaʻa ka mea hoʻoheheʻe pololei o ka recarburizer non-graphite, akā hoʻopuehu mālie ke kalapona a hoʻoheheʻe ʻia i loko o ka hao i hoʻoheheʻe ʻia i ka wā e hele ai.No laila, ʻoi aku ka kiʻekiʻe o ka carbonation rate o ka recarburizer graphite ma mua o ka recarburizer non-graphite.

Nā nīnau e hoʻolohe ai i ke koho ʻana i kahi carburant:

1. E ho'āʻo e hoʻohana i ke kiʻekiʻe-mehana graphitization-hana recarburizers (ʻoi aku ka kiʻekiʻe o ka wela lapaʻau, ka maikaʻi o ka graphitization hopena), e like me graphite electrodes a graphitized aila coke.Ma muli o ka recarburizer maikaʻi he kiʻekiʻe absorption rate a me ka wikiwiki dissolution rate, ʻoi aku ka maikaʻi o ka hoʻemi ʻana i ka ikehu, a hiki ke hoʻonui pono i ka nucleation core o ka hao hoʻoheheʻe a hoʻomaikaʻi i ka maikaʻi metallurgical;

2. E koho i nā carburizer me nā mea haumia haʻahaʻa e like me ka sulfur a me ka nitrogen.He kiʻekiʻe nō hoʻi ka maʻiʻo nitrogen o ka recarburizer me ke kiʻekiʻe sulfur.Ke ʻoi aku ka kiʻekiʻe o ka naikokene o ka hao i hoʻoheheʻe ʻia ma mua o ka neʻe ʻana o ke kaulike, ua maʻalahi ka hana ʻana i nā pores nitrogen e like me ka māwae, a ʻo ka ductile hao i hoʻoheheʻe ʻia he prone i ka hoʻohaʻahaʻa i nā hemahema i nā ʻāpana paʻa paʻa, a ʻo ka ʻike o nā mea haumia. kiʻekiʻe.Hoʻonui i ka manaʻo o ka hoʻokomo ʻana i ka slag;

3. E like me ka nui o ka umu ahi, ke koho ʻana i ka nui o ka nui o ka recarburizer hiki ke hoʻomaikaʻi maikaʻi i ka wikiwiki absorption a me ka helu o ka carburant e ka hao i hoʻoheheʻe ʻia.
