Product Description

YHMK series exothermic-insulating riser sleeves


Excellent advantages of high feeding efficiency

Reduce casting slag inclusions and pores

Improve qualified castings, reduce the cost.

Reduce workload in cleaning and re-welding


It is made of light thermal-insulating material which is used together with exothermic-insulating agent that is not polluted to the alloy. So it can guarantee high feeding performance. With the advantages of low gas evolution, good permeability, high exothermic resistance. Especially Being applicable for medium and large iron and steel castings, improving casting yield, the products divided into cylindrical, oval, necking-down and side sleeves etc, and it can also provide the corresponding lid.
