Mo te whakarewa i te rino, te oumu hiko ranei i roto i te ahumahi whakarewa, ko te kaupapa matua o te hangarau carburizing ko te whakamahi i te whanariki iti, te hauota iti, te porosity teitei.kaihoko waro.

Petroleum coking carburizer matua whakaputa rohe o Liaoning, Tianjin, Shandong me etahi atu wahi.I roto i a raatau, ko Liaohe Oilfield te takenga mai o te hinu whanariki iti o te ao, no reira ko te mea iti rawa te kiko whanariki i roto i te petroleum coke.

Te porosity okaihoko warowhai wāhi nui hoki i roto i te pānga carburizing me te auau absorption o carburizing kaihoko.Na roto i te tukanga whakaputa, ka whakatuwherahia nga pores o te hinu hinu coke carburizing agent ki te whakanui ake i te waahanga mata motuhake o te kaihoko carburizing, a he tino kaha te hua o te hua ka taea te rewa ki roto i te rino, kia nui ake ai te tere o te whakauru me te pai o te carburizing. .
