Rau cam khwb cia hlau los yog hluav taws xob rauv smelting nyob rau hauv lub casting kev lag luam, cov tub ntxhais ntawm carburizing tshuab yog siv tsawg leej faj, tsis tshua muaj nitrogen, porosity siab.carburizing tus neeg sawv cev.

Petroleum coking carburizer cov chaw tsim khoom ntawm Liaoning, Tianjin, Shandong thiab lwm qhov chaw.Ntawm lawv, Liaohe Oilfield yog lub hauv paus chiv keeb ntawm cov roj av uas tsis tshua muaj sulfur crude, yog li cov ntsiab lus sulfur hauv roj av coke yog qis tshaj.

Qhov porosity ntawmcarburizing tus neeg sawv cevKuj tseem ua lub luag haujlwm tseem ceeb hauv cov nyhuv carburizing thiab qhov nqus ntawm carburizing tus neeg sawv cev.Los ntawm cov txheej txheem tsim khoom, cov pores ntawm cov roj av coke carburizing tus neeg sawv cev tau qhib kom ua kom tiav qhov chaw tshwj xeeb ntawm carburizing tus neeg sawv cev, thiab cov khoom muaj super permeability thiab tuaj yeem yaj sai sai rau hauv cov hlau, kom ua kom qhov nqus tau zoo tshaj plaws thiab muaj txiaj ntsig carburizing. .
