Spherical Graphite Recarburizer Enhances Metal Quality

Graphitized spherical recarburizerThe specifications of spherical graphite carburizers affect carbon enrichment efficiency and cast iron quality.The fixed carbon content of a foundry-use spheroidal graphite recarburizer is its active ingredient; the higher, the better.Ash content in a metallurgical spherical graphite carburizing agent is an impurity and should be kept as low as possible; high ash content impedes carbon absorption and increases slag volume and power consumption.The sulfur content of ductile iron graphite recarburizers is also crucial; ductile iron requires low sulfur, while gray iron requires a certain level of sulfur.High levels of volatile matter and moisture in foundry spherical graphite carbon raisers can easily cause porosity in castings. Using our carbon-increasing agents can significantly improve the yield rate of castings and markedly reduce porosity, inclusions, and other defects.Our factory’s metallurgical spherical graphite carburizing agent features a high c…
