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).

Range of muffle electric furnaces used for preparation of casting cylinders.The adjustable temperature up to 850°C allows the wax dissolution and firing the plaster inside the hollow cylinder.The furnaces are equipped in the bottom of the chamber with a grill and drawer to recover the wax.
Our furnaces are equipped with 2 heating chambers which work with separated heating zones with separate setting of temperatures. 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 chamber can withstand strong temperature changes. Internal sliding blocks avoid wear and tear of chamber because of belt running. Cooling chamber is cooled by water. A flange keeps together the chambers and a nozzle on it let gas go inside. Two burners, placed in front of both extremities of tunnel, avoid entrance of oxygen and improves de-oxidation.
