Graphite Steel Rolls 190 (GS190) used in the blooming mill has good thermal conductivity and can effectively dissipate heat and keep the temperature of the roll stable, which is beneficial to improving the surface quality and dimensional accuracy of the rolled products. Graphite Steel rollers 190 (GS190) are suitable for various roughing mills and can meet the rolling needs of metal billets of different sizes and materials. Compared with some more expensive roll materials, graphite steel rolls have lower manufacturing costs, but their performance can still meet the requirements of the blooming mill and is cost-effective.
