Insulating riser for refractory hollow materials

Changxing Hengchuan Refractory Materials Co., Ltd. is a manufacturer of various insulation nozzles, offering wholesale prices for insulation nozzles all year round. Welcome to inquire and purchase!

Insulating risers are risers made from insulating materials, where the metal liquid in the insulating riser takes longer to solidify than in a standard riser, saving metal. The insulating riser sleeve is composed of insulating materials, adhesives, and refractory aggregates, commonly available types include expanded vermiculite composite, ceramic ball composite, and fiber composite, etc. Riser sleeves made from these materials are lightweight, have high refractoriness, excellent insulation properties, and can also improve the yield rate of the process.

Our high-strength fiber composite insulating riser features excellent insulation properties, high耐火 resistance, strong feeding ability, minimal shrinkage after reheat, ease of use, and is convenient for promotion. It has consistently received high praise from our customers over the long term.

This insulating riser is widely used in the production of castings made from various grades of cast steel, cast iron, and non-ferrous metals. The use of this product extends the cooling time of the metal, enhances the feeding effect, and can increase the yield of casting processes by about 20%, reduce production costs by about 30% to 40%, and decrease the riser weight by 40% to 50%. It saves on metal melting and riser cutting costs, reduces sand and metal losses, and JN labor, thereby lowering casting production costs, improving the inherent quality and density of castings, and enhancing economic benefits. After casting with this product, there is minimal shrinkage at high temperatures, the insulating riser sleeve does not deform or expand, the riser has a smooth and regular appearance, and after feeding, it assumes a "flat butterfly" shape.
