Carburising / carbonitriding furnaces

ALLCARB © low pressure carburising vacuum furnaces from B.M.I. offers perfect homogeneity of the carburizing atmosphere in the batch, expected metallurgical results without tests, carburization of holes with a small diameter and better control of the C content in the layer.

The carburising process under controlled atmosphere furnaces is controlled by means of an oxygen or lambda probe, which maintains the values of carbon potential - Cp at the selected level and thus prevents supersaturation of the emerging layer and / or insufficient layer formation and thus increase the economics of chemical-heat treatment.
