The "ETNA" series bring together the range of continuous casting furnaces with capacity of the crucible from 10 up to 140 kg. The user is helped in his work from a graphical interface and display. Access to the machine body is secured by a tubular frame and movable panel for easy maintenance. The drive system for profile is made aluminum body is completely cooled and driven by a stepper motor coupled to a planetary gear, it should be integrated with the casting chamber. All this system is closed by a cover easy to remove: the access to equipment melting (Ceramic jacket, chain bushings, thermocouples) is very fast minimizing the time for replacement. The cooling socket, in harmony with the equipment has been refined so that it can offer the best possible performance. The heart of the machine consists of a mid-frequency system completely designed and built by the Technical Opdel. These furnaces are often used for special profiles where the amount of metal to be melted is high. It can use accessories such as shears or saws for the cutting of profile, trays for cooling the same. In some case an additional tilting head can fill the empty crucible directly with liquid metal in order to reduce the stop of the production.
