FERRUX is a range of exothermic insulating anti-piping compounds for covering iron and steel risers. FERRUX improves feeder performance and minimises skull formation.
FERRUX powders react exothermically after contact with the liquid metal in the feeder and the powder expands to create a highly insulating residue. This double effect of heating and insulating the feeder head surface permits the longest possible action of the atmospheric pressure on the liquid feeder metal. This leads to an optimum yield of the feeder and to the prevention of secondary shrinkage cavities.
KAPEX are a range of preformed lids suitable for application to KALMIN and KALMINEX open feeders. On application, an exothermic reaction causes KAPEX to expand by as much
as 200%, producing a highly insulating cover layer.
KAPEX lids are suitable for all types of exothermic and insulating feeder sleeves and can also be applied to sand feeders. They ensure optimum feeding for all grades of iron and steel castings and have a number of advantages
over traditional powdered covers:
- dust free and very low fume
- uniform insulation across the whole feeder surface
- elimination of human error
- provides protection for the mould cavity between
moulding and pouring
KALBORD flexible insulating boards are ideal for use as insulating feeders for very large steel, iron and copper alloy castings, especially for feeders with a diameter > 500 mm.
KALBORD prevents an early skin formation in the feeder and the metal surface in the feeder shows a uniform flat sinking.
Supplied in mat form for on-site assembly, KALBORD overcome the problems of stock control and storage of very large feeder sleeves.
