Abstract

The invention relates to a metal heat-treatment controllable slow-cooling device and an intelligent on-line monitoring system which are characterized by comprising a furnace body (1) and a blower (4), wherein an internal cavity of the furnace body (1) is provided with an ascending / descending platform (6), a heat exchanger (5) and a temperature detector (8); the upper side wall of the furnace body(1) is provided with a workpiece inlet / outlet (10), the blower is positioned outside the furnace body (1), an air outlet (41) of the blower is communicated with the internal cavity of the furnace body (1), an air return port (42) of the blower is communicated with an air outlet (51) of the heat exchanger, a unidirectional air passage is formed among the internal cavity of the furnace body (1), the air outlet (41) of the blower and an air inlet of the heat exchanger (5), and the ascending / descending platform (6) is positioned in the unidirectional air passage; and the blower (4), the heat exchanger (5) and the ascending / descending mechanism (6) are respectively provided with a control input signal end. The invention ensures that a carburization component does not generate oxidation and decarbonization during slow cooling, and realizes the automatic production of the carburization component in a controllable atmosphere.

Description

technical field [0001] The invention relates to a controllable slow cooling device for metal heat treatment and an intelligent on-line monitoring system, which is suitable for the controllable cooling system under the condition of non-oxidative decarburization after carburizing with on-line precise and controllable multifunctional bottom loading. It belongs to the technical field of metal heat treatment equipment. Background technique [0002] Carburizing, quenching and tempering are the main heat treatment methods for metal surface strengthening. Carburizing increases the carbon content of the surface layer of the metal workpiece. Through subsequent quenching and tempering, the hardness of the surface of the metal workpiece is greatly improved, and the wear resistance and service life are increased; at the same time, the core of the workpiece obtains a good combination of strength, plasticity and toughness. , to meet the requirements of maintaining good strength and toughn...
