| Dawai:
Building my furnace? I found a local "boiler" repair company who buys the castable refractory by the truck load. Purchased left over from them. There is two grades here from what I remember, one ultra high temp for steels and other metals, and one lower for aluminum less than 2k F. Mine has sat now for about ten years in the weather, cast in a old hot water heater. I am not the greatest caster there is and had about a 40-60 percent failure rate in my castings. I suspect it was overheating the metal and poor sprue forming. Pouring metal while "all alone" is not a real good idea either. I had two trolleys put up, till one jumped the limit switch and busted a $4k gearbox. (got from a scrapper for weight, but could not replace it cheaply) Funny, the camera I had on it always showed "green glow" instead of the red-orange normal. I talked to the wife about tying it into the barbeque grille as a smoker-wood burner, it is just sitting there. I had last machined a bottom drop pot with a taper plug valve. Keeps the slag on top. A old modified pressure cooker was how I debubbled my lost wax castings. (what would fit in there) I had hoped to go hang out with some "better foundry workers and learn from them".. there is a great post over on Hamb. I am not too old to learn.. yet. My career expertise was electrical, instrumentation, I am interested in about everything from Solar to magnetics and still have not outgrown the fast car-motorcycle lure, not killed me yet.. If anyone is casting in the south-east or within close driving distance?? Lemme know.. thou I might be sleeping in my car-truck.. |
