Ukuze kuncibilikiswe insimbi noma isithando somlilo sikagesi embonini yokuphonsa, umnyombo wobuchwepheshe be-carburizing ukusetshenziswa kwesibabule esiphansi, i-nitrogen ephansi, i-porosity ephezulu.i-ejenti ye-carburizing.

I-Petroleum coking carburizer ikhiqiza izindawo eziphambili ezikhiqiza i-Liaoning, i-Tianjin, i-Shandong nezinye izindawo.Phakathi kwazo, i-Liaohe Oilfield iwumthombo womhlaba kawoyela ongahluziwe wesulfure ephansi, ngakho okuqukethwe kwesibabule ku-petroleum coke kuphansi kakhulu.

I-porosity yei-ejenti ye-carburizingfuthi idlala indima ebalulekile kumphumela wokungcwatshwa kwe-carburizing kanye nezinga lokumuncwa kwe-ejenti yokungcwaba.Ngenqubo yokukhiqiza, izimbotshana ze-ejenti ye-petroleum coke carburizing zonke zivulwa ukuze kwandiswe indawo ethile ye-ejenti yokungcwaba, futhi umkhiqizo unokungeneka okuphezulu futhi ungancibilika ngokushesha ensimbi, ukuze kwandiswe izinga lokumuncwa kanye nokungcwatshwa kwe-carburizing ngokuphumelelayo. .
