Series "FR"
Description

Our annealing furnaces are made by a tubular frame and panels with Louvres for air exchange. Tubular system makes general maintenance interventions easier. Resistence and special refractory insulating panels, with high thermal features, make up heating muffles. Special stainless steel heating chambers can resist strong temperature changes. Nozzles inside the chamber let protection gas in. A burner placed in front of the chamber avoids entrance of oxygen and improves de-oxidation. A stainless steel shovel lies inside. When metal is annealed, you just push the pale till the bottom of cooling chamber and throw it in the water tub for instantaneous cooling (or let it Lie in the cooling chamber to cool, taking some time). Treated material is recovered from the tub manually or by a pneumatic piston (optional).
