Electric retort horizontal furnace, HVF type is designed to carrry out heat and head and chemical treatment in the atmosphere generated from dissociated amonnia or innert gases within the range of temperatures from 560 do 700°C.

Construction of the furnace make possible to carry out heat treatment processes by the user. It is especially suitable for nitriding and carbonitriding process. Furnace atmosphere is generated from dissociated amonnia, which undergoes decomposition just before the introduction to the furnace retort in the cracking system. Propan is applied as carburizing medium.Application of various additives in different stages of process , taking into account a charge and a furnace size, provides generation of proper microstructure and high - grade mechanical properties.
