Exothermic-insulating Covering Powder

The self-developed and produced XY-723 series exothermic-insulating covering agent is applicable for the coverage of open riser sleeves and ideal for various foundry alloys.

Characteristics

Heat generated from the exothermic materials in the covering powder could make up for the heat loss of riser sleeves, catalyst could guarantee a complete exothermic reaction.

The insulating materials in the covering agent have good spreadability, make perfect heat insulation.

Reduce the heat dissipation rate on the top of riser sleeves, extend the coagulation time of the riser sleeves for a better feeding.

The cavity of the riser sleeve is U shape or T shape, increase the safety height, prevent the shrinkage defects, improve technical production rate, save the metal liquid and energy.




Specifications

Light brown granules.




How to use

Addition rate: 1.0-1.5% of liquid metal weight on the riser sleeve, or covering thickness to 10-15% of the riser sleeve’s diameter. 
Addition method: add the covering powder when the liquid metal rises to 1/2 or 2/3 of the riser sleeve. 
It has better performance when XY-723 series exothermic-insulating covering powder is matched with XY-200/ XY-300 series riser sleeves.




Packing and Storage

Packed in woven bags and covered with plastic film, 25kg net weight. 
Store in fireproof and waterproof dry place.
