No ke kila kila a i ʻole ka umu uila i hoʻoheheʻe ʻia i ka ʻoihana hoʻolei, ʻo ke kumu o ka ʻenehana carburizing ka hoʻohana ʻana i ka sulfur haʻahaʻa, haʻahaʻa nitrogen, porosity kiʻekiʻe.mea hana carburizing.

ʻO ka Petroleum coking carburizer nā wahi hana nui o Liaoning, Tianjin, Shandong a me nā wahi ʻē aʻe.Ma waena o lākou, ʻo Liaohe Oilfield ke kumu honua o ka ʻaila sulfur haʻahaʻa haʻahaʻa, no laila ʻo ka haʻahaʻa loa o ka sulfur ma loko o ka petroleum coke.

ʻO ka porosity omea hana carburizingHe hana koʻikoʻi nō hoʻi ia i ka hopena carburizing a me ka helu absorption o ka carburizing agent.Ma o ke kaʻina hana, ua wehe ʻia nā pores o ka petroleum coke carburizing agent e hoʻonui i ka ʻāpana kikoʻī o ka carburizing agent, a he super permeability ka huahana a hiki ke hoʻoheheʻe koke ʻia i loko o ke kila, i mea e hoʻonui ai i ka helu absorption a me ka carburizing maikaʻi. .
