LOI Wesman is active in the fields of heat treatment plants for transmission, engine and other parts for vehicle production covering all types of steel as well as non-ferrous items. Pusher type furnaces have been standard gas carburizing solution for mass production parts for decades. The main disadvantages are limited throughput capacity imposed by limited length of pusher furnace and multi chamber complex design for different atmosphere.



LOI has developed a new Rotary Hearth furnace to overcome the capacity limitations and optimized the control of temperature & atmosphere zone. The treatment zones e.g; heating-up, carburizing ,diffusion zones,  and the charging & discharging sections are separated by intermediate doors.


The advantages of this system are:

Short treatment cycles
Temperature in excess of 10000 is possible
Low maintenance cost
High reproducibility
Low operating cost
