Product Details

RJZ3 series pre-vacuum pit annealing resistance furnace

Brief

RJZ3 series pre-vacuum pit annealing resistance furnace is energy-saving and high precision temperature control vacuum furnace, mainly used for aerospace aircraft manufacturing industry, automobile manufacture industry and precision parts for bright non-oxidation annealing, non-oxidation and no decarburization heat, quenching, annealing, tempering and spheroidize annealing heat treatment. The workpiece is loaded in the furnace tank, firstly forvacuum, then filling the protective atmosphere, can be used for non- oxidation annealing heat treatment.
