The activation plant is used to remove the passivating metal oxide layer from stainless steel workpieces. This is necessary in order to be able to carry out a nitriding process and obtain a hard surface. Depending on the shape and size of the workpieces, they are brought into the treatment room in baskets or charging racks.

Roller hearth furnace for bainitizing
