Type-B Cylindrical Blind Feeder Exothermic Riser Sleeve For Casting

Cast steel, ductile iron and non-ferrous alloy castings have a large volume shrinkage rate during solidification and molding, and shrinkage defects are easily generated inside the castings, which seriously deteriorate their mechanical properties and service life. In order to effectively prevent shrinkage cavities and shrinkage defects in castings, riser sleeves are usually set at appropriate positions on the castings to compensate for the solidification shrinkage of the castings.
