Feeding Auxiliries

Conventional sand feeders give poor casting yield, and have large casting contact area  which lead to high fettling cost. The principles of using exothermic and insulating  sleeve as a method of increasing feeding efficiency of a feeder have been well established for a number of years.

 

FRM provides range of exothermic/insulating sleevess. With their exothermic/insulating nature, the feeding efficiency of  feeder sleeve is high and so a conventional sand feeder  can be replaced by much smaller  sleeve, whilst maintaining feed performance. Hence, casting yield is significantly increased and due to smaller contact area of the  feeders, fettling cost is reduced

 

Sleeve minimises initial chill as the feeder gets filled.  Gradually,as the head settles, a vigorous exothermic reaction is initiated and a large amount of heat is made available to the riser metal.

On the completion of the exothermic phase, the insulating properties of the sleeve matrix take over again ensuring the total solidification time of the riser metal is substantially extended.

Sleeve therefore has a triple action - initial insulation an exothermic second phase and final long term insulation - thus offering optimum feed characteristics.
