This high-efficiency exothermic and heat-insulating riser sleeve has low density, good strength, toughness, and is especially suitable for cast iron, cast steel, and various molding processes.
inquiry
The heating and the heat-insulating exothermic sleeve has high calorific value, high strength, and good toughness. It is made of light heat-generating heat-insulating material, combined with a heat-generating agent with high calorific value and no pollution to the alloy, to ensure that it has high feeding performance. Its low gas generation, good air permeability, and high refractoriness make the return material clean.
When the high-temperature molten metal contacts the riser sleeve, an exothermic reaction begins, which will further heat the molten metal, prolong the solidification time, further reduce the volume of the riser, and significantly improve the process yield.
Compared with ordinary risers, the use of this product can prolong the cooling time of the molten metal, enhance the feeding effect, improve the yield of the casting process, save energy and labor, reduce the production cost of the casting, and improve the inherent quality of the casting and the compactness of the casting. , improve economic efficiency.
