Abstract
The present invention relates to a kind of GCr15 steels cold roll quenching technical, it is characterised in that（1）Annealed in batch-type furnace, stove is cooled to 680-690 DEG C at 780-790 DEG C, be then incubated 5h, stove is as cold as 250 DEG C or so and come out of the stove；(2) workpiece is transferred in a batch-type furnace, 2.5-3h is incubated at 600-650 DEG C, be then transferred into heating furnace, be heated rapidly to 930-950 DEG C, heat time to 30min；（3）Cooled down as quenching press using 5% NaOH at room temperature, cool time is 20-25min；（4）Roll is cooled to 100-110 DEG C or so after quenching, is tempered then into fluid, and temperature is 160-180 DEG C, is incubated 3h, and soak times are 2 times.
Description
Technical field
The invention belongs to Field of Heat-treatment, a kind of GCr15 steels cold roll quenching technical is particularly belonged to.
Background technology
Cold roll is the important technological equipment in Rolling production, it is a kind of cold deformation mould, during steel rolling, because the material resistance of deformation being extruded is than larger, the working portion of mould is subject to strong friction and extruding, therefore mould should have high intensity, high rigidity and wearability, and preferably toughness.
The content of the invention
It is an object of the invention to provide a kind of GCr15 steels cold roll quenching technical, the quenching process is simple, it is possible to increase the various aspects of performance of cold roll so that the intensity of cold roll, hardness and wearability are obviously improved.
To achieve these goals, technical scheme is as follows：
A kind of GCr15 steels cold roll quenching technical, it is characterised in that（1）Annealed in batch-type furnace, stove is cooled to 680-690 DEG C at 780-790 DEG C, be then incubated 5h, stove is as cold as 250 DEG C or so and come out of the stove；
(2) workpiece is transferred in a batch-type furnace, 2.5-3h is incubated at 600-650 DEG C, be then transferred into heating furnace, be heated rapidly to 930-950 DEG C, heat time to 30min；
（3）Cooled down as quenching press using 5% NaOH at room temperature, cool time is 20-25min；
（4）Roll is cooled to 100-110 DEG C or so after quenching, is tempered then into fluid, and temperature is 160-180 DEG C, is incubated 3h, and soak times are 2 times.
The beneficial effect of the invention is：The disclosure of the invention quenching process is simple, it is possible to increase the various aspects of performance of cold roll so that the intensity of cold roll, hardness and wearability are obviously improved.
Specific embodiment
Specific embodiment of the invention is described with reference to embodiment, to be better understood from the present invention.
The invention discloses a kind of GCr15 steels cold roll quenching technical,（1）Annealed in batch-type furnace, stove is cooled to 680-690 DEG C at 780-790 DEG C, be then incubated 5h, stove is as cold as 250 DEG C or so and come out of the stove；
(2) workpiece is transferred in a batch-type furnace, 2.5-3h is incubated at 600-650 DEG C, be then transferred into heating furnace, be heated rapidly to 930-950 DEG C, heat time to 30min；
（3）Cooled down as quenching press using 5% NaOH at room temperature, cool time is 20-25min；
（4）Roll is cooled to 100-110 DEG C or so after quenching, is tempered then into fluid, and temperature is 160-180 DEG C, is incubated 3h, and soak times are 2 times.
The disclosure of the invention quenching process is simple, it is possible to increase the various aspects of performance of cold roll so that the intensity of cold roll, hardness and wearability are obviously improved.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; some improvements and modifications can also be made, these improvements and modifications are also considered as protection scope of the present invention.
