There are not too many new innovative solutions in heat processing. Nevertheless, they exist. An example is the NANO system from ECM Technologies from Grenoble.<\/p>\n

It is a flexible device, fully automatic, processing batches up to 100 kg. Although the device has a uniform concept, it can be equipped with 3 to 6 heating chambers as variants, all with the option of low-pressure carburizing (LPC), with quenching in gas flow up to 20 bar (N2) or in oil, or in combination with both.<\/p>\n

The size of the working space is 600 mm wide, 500 mm lenght and 250 mm high. In the basic design, these heating chambers are 3 of this height, but there is also a variant with 6 chambers with a chamber height of only 150 mm.<\/p>\n

Thanks to the number of chambers, implemented low-pressure carburizing, automation and robotization, it can be seen that when the device is equipped with 6 chambers, the production cycle for CHD = 0.6 mm is 10.5 min, for CHD = 0.9 mm 13 min and for CHD = 1.3 mm is then 18.33 min. What can you imagine so far? In 1 hour of operation, the device is capable of processing 570 Kg with CHD=0.6 mm, 460 kg with CHD 0.9 mm, and 327 kg with CHD = 1.3 mm. If we were only to make quenching in the oil or gas, then the productivity would be at least 600 kg per hour.<\/p>\n

If we compare it with Ipsen-type devices, the diffusion depth of carburizing with CHD = 1.3 mm with subsequent hardening will take us about 7 hours. For size M it is a batch of 500 kg, for size L it is 1000 kg. The hourly performance is therefore 500\/7 = 71.4 kg for size M, and 1000\/7 = 142 kg for size L. However, the view of NANO changes significantly. David becomes Goliath. NANO is almost twice as powerful as Ipsen size L.<\/p>\n

In the basic configuration with 3 chambers, the performance of NANO corresponds to roughly half the values, i.e. it will be around 300 kg\/hour for hardening, and for CHD = 1.3 mm then 160 kg\/hour. This is a value comparable to the Ipsen size L.<\/p>\n

The NANO device itself can be supplemented with any number of other devices such as washing machines, annealing and tempering furnaces, cryo equipment, or equipment for carbonitriding. Also important, we don’t need any shaft. The entire assembly is at floor level and can be placed in a production line with machine tools.<\/p>\n

And what are the benefits of NANO?<\/p>\n
