I have been using the addition of stainless steel 'needles' to reinforce the castable layer in the high tec. ovens, during my workshops, over the past 4 years, with great sucess.
The 'needles', oddly called 'melt extract', are about 1mm x 25mm and have come from the furnace/kiln industry to reinforce their cast or sprayed refractories.
I use about 3 kg to an oven of about 1200mm x 1000mm dimensions.
I have a workshop in Calgary, Canada, next northern summer and I was hoping some North American forum participants may know where I might be able to purchase small supplies of this material.
It is not difficult for me to carry 3 kg. with me but I would like to be able to advise the participants, who wish to build their own ovens where the 'needles' may be purchased.
I would be grateful for any advice.
