The present application relates to the technical field of
metal material heat treatment, in particular to a heat treatment furnace device and method capable of controlling temperature and
cooling speed, wherein the furnace body is internally constituted as a
hearth, the output end of the air supply
system is located at the lower region of the
hearth through the furnace body; the flow equalizing
system is arranged at the lower region of the
hearth and is in communication with the output end of the air supply
system; the workpiece is placed on the flow equalizing system; the circulation and exhaust system is arranged at the upper region of the hearth and is in communication with the interior of the hearth, the
temperature monitoring system is arranged on the circulation and exhaust system and is directly above the workpiece; the
control system is electrically connected with the air supply system, the circulation and exhaust system and the
temperature monitoring system. The present application effectively solves the problems of
insufficient cooling speed and poor cooling uniformity in the prior art.
