CF and CDF High Temperature Infrared Furnaces for Firing & Drying
The new Despatch CF and CDF Series infrared furnaces are ideal for process applications that require rapid ramp-up and cool-down rates as well as provide consistent quality—as required in photovoltaic cell production.
Very fast ramp rates optimize contact formation on silicon wafers with shallow emitters and silicon nitride coating. Rapid heating and cooling allows firing the contact through the silicon nitrate while rapid cooling prevents damage to the junction. The rapid heating and cooling requires faster belt speeds which enhances throughput as a secondary benefit.
All models feature the most advanced ergonomic designs available, to speed maintenance and minimize downtime. With the push of a button, the entire chamber lowers for easy accessibility—no disassembly or expensive service calls for cleaning and maintenance. All electronic components are situated at eye level for easy and safe access. |

| It's suitable for the Heating of the pieces of medium/large diameters (40-120 mm) with low output rates (max 200 pieces/h) and automatic piece loading beginning from aligned bar magazine. The slide for the piece loading in the three coils translates in sequence from one to another coil: the introduction of a cold piece let go out the piece in temperature. It' s suitable for applications like forging of axle shafts and similar pieces. |

The use of induction furnaces for heating material that must undergo subsequent deformation by hot pressing, is now a consolidated practice that offers great advantages with respect to traditional heating systems such as gas furnaces, resistance or radiant panels furnaces, etc.
The great advantage in the pressing sector, where the heating process for work material is required continuously, is the total absence of pre and post operation downtimes. Other advantages include rapid reaction times to any temperature variation, rigorous reproducibility of operation parameters, easy automation of the entire line, easy adaptability to the different production needs of presses, hammers, forging machines, etc.
The electrical power required by the induction system depends on production needs, on the temperature, and on the cross-section and the type of material being heated. With regards to this last aspect, we would like to emphasize that furnaces can be built for any metallic material ( ferrous or non ferrous ) and of any cross-section ( circular, squared, tubular, flat, etc. ). |

Steel rods and pipes are mainly heat-treated using roller hearth furnaces. The high temperature consistency and low energy consumption of these furnaces, normally gas-fired, ensure reproducible quality and short treatment times. The processes used for heat treating non-alloyed and alloyed carbon steel pipes at temperatures between 450°C and 1050°C include stress relieving, recrystallizing, normalizing, soft annealing and spheroidizing in indirectly fired continuous roller hearth furnaces. For the spheroidizing of pipes made from high-carbon ball bearing steel, vacuum vestibules to completely isolate the furnace atmosphere from the surrounding air are essential, at least at the furnace entry. Vacuum vestibules are also needed at the entry and exit of continuous roller hearth furnaces for the bright solution annealing of high-alloy austenitic pipes. In the heat treatment of copper alloy bars and pipes, zinc, which can be easily oxidized, is the critical element in the alloy. Rapid cooling is essential to ensure that the zinc is kept in solution. This can be achieved using optional high-convection cooling chambers with a hydrogen atmosphere.
