China low price exothermic riser sleeve

タイトルまたは説明

The exothermic insulation riser head has adopted good insulation material and high efficient exothermic. There are little quenching effect, once the liquid steel was pour into the riser head, the exothermic reaction will be activated, then the riser head will heat the liquid steel with it’s fever. After the reaction, the insulation material will ensure the coagulation time of the liquid steel. The best feeding efficient comes from the characters: Initial adiabatic, then fever, heat preservation for a long time in the end.
