Abstract
The present invention relates to a kind of metal heat treating methods, the waste heat isothermal heat treatment method of especially a kind of low-carbon alloy structural steel. The technical problem to be solved in the present invention is to provide the low-carbon alloy structural steel heat treating method that a kind of forging need not reheat normalizing. For solving the problems of the technologies described above, the present invention comprises the steps: by intermediate frequency heating bar preform forging shaping edge-cutting and hole-punching, after punching, forging temperature is chilled between 800 ~ 850 DEG C in atmosphere in advance, forging is inserted temperature again in the continuous resistance stove of 650 �� 10 DEG C, insulation 60min, then comes out of the stove empty cold. Adopt aforesaid method, forging Hardness Control between 170 ~ 190HB, technical requirements can be met completely, organize and also ensured very well, and avoid forging and reheat normalizing, reduce cost, shorten the production cycle.
Description
Technical field
The present invention relates to a kind of metal heat treating methods, the waste heat isothermal heat treatment method of especially a kind of low-carbon alloy structural steel.
Background technology
In order to improve tissue, reduce hardness, eliminate forging stress, for products such as the made forging wheel blanks of low-carbon alloy structural steel 20CrMnTi, prior art, it is generally required to employing reheats normalizing treatment, must cause the production cycle of product long, production cost height like this.
Summary of the invention
The technical problem to be solved in the present invention is to provide the low-carbon alloy structural steel heat treating method that a kind of forging need not reheat normalizing.
For solving the problems of the technologies described above, the present invention comprises the steps: by intermediate frequency heating bar preform forging shaping edge-cutting and hole-punching, after punching, forging temperature is chilled between 800 ~ 850 DEG C in atmosphere in advance, forging is inserted temperature again in the continuous resistance stove of 650 �� 10 DEG C, insulation 60min, then comes out of the stove empty cold.
Adopt aforesaid method, forging Hardness Control between 170 ~ 190HB, technical requirements can be met completely, organize and also ensured very well, and avoid forging and reheat normalizing, reduce cost, shorten the production cycle.
Embodiment
1. bar passes through intermediate frequency heating, then precast billet, forging and molding, trimming, punching. After punching, forging temperature is chilled between 800 ~ 850 DEG C in atmosphere in advance.
2. the forging of step 1 is inserted temperature in the continuous resistance stove of 650 �� 10 DEG C, insulation 60min, then come out of the stove empty cold.
Claims (1)
1. the heat treating method of a low-carbon alloy structural steel, comprise by intermediate frequency heating bar preform forging shaping edge-cutting and hole-punching, it is characterized in that: after punching, forging temperature is chilled between 800 ~ 850 DEG C in atmosphere in advance, forging is inserted temperature again in the continuous resistance stove of 650 �� 10 DEG C, insulation 60min, then comes out of the stove empty cold.
