Non-metallic Inclusions Control for High Strength Anti-HIC X65 tube Steel
The hot metal fed converter in Panzhihua Steel Company is characterized by high sulfur content of 0.085% and high phosphorus content of 0.133%.Under this condition,some technologies like control of sulfur and TO content,ladle slag optimization,calcium treatment and protective casting were used in practice,and the desired result of TO as low as 0.0014% and sulfur content of 0.0023%was achieved,which met the cleanness requirements by anti-HIC X65 tube steel.With the help of inclusion control technology,grade of inclusions in as-cast steel was less than 0.5.In addition,total amount of inclusions was only 0.0044% which dispersed in slab in form of small spherical particle.
