Cylindrical Exothermic Insulation Blind Feeder Riser Sleeve For Casting

The exothermic riser sleeve is mainly made of heat-generating and thermal insulation materials. It is used in the foundry industry, especially for steel castings and ductile iron parts to improve the feeding efficiency of the riser sleeve. After the molten metal is poured on the heating riser sleeve, the heating material burns to release a large amount of heat, so that the molten steel in the riser delays the solidification time and improves the feeding efficiency.
