Float Bead Exothermic Insulating Riser Sleeve
I.High temperature resistance: The fire resistance of floating beads can reach ≥ 1610 ℃, suitable for high-temperature casting environments.
II.Thermal insulation performance: Drifting beads have good thermal insulation properties, which can effectively slow down the cooling rate of castings and maintain temperature gradients.
III.Significantly improve the density and internal quality of castings, and extend their service life.
