Embodiment 1

[0035] The present invention also provides an annealing method, comprising the steps of:

[0036] S1. After clamping the material to be processed in the device, heat the inside of the box 16 through the heating plate 15, heat it to 550°C at a speed of 100°C / h, and keep it warm for 2 hours;

[0037] S2. After S1 is completed, stop the continuous heating of the heating plate 15, so that the raw materials are naturally cooled to 450°C along with the box body 16;

[0038] S3. After completing S2, open the slide plate 13, open the radiator 2, and allow the raw material to fully contact with the air for cooling, so that the temperature is cooled to 180°C;

[0039] S4. After completing S3, turn off the radiator 2, turn on the heating plate 15, and continue heating. After heating the raw material to 220° C., keep it warm for 1 hour, and cool it to room temperature in the air.

Embodiment 2

[0041] S1. After clamping the material to be processed in the device, heat the inside of the box 16 through the heating plate 15, and heat it to 600°C at a speed of 110°C / h, then keep it warm for 3h;

[0042] S2. After S1 is completed, stop the continuous heating of the heating plate 15, so that the raw materials are naturally cooled to 475°C along with the box body 16;

[0043] S3. After completing S2, open the slide plate 13, open the radiator 2, and allow the raw materials to fully contact with the air for cooling, so that the temperature is cooled to 195°C;

[0044] S4. After completing S3, turn off the radiator 2, turn on the heating plate 15, and continue heating. After heating the raw material to 230° C., keep it warm for 2 hours, and then cool it to room temperature in the air.

Embodiment 3

[0046] S1. After clamping the material to be processed in the device, heat the inside of the box 16 through the heating plate 15, and heat it to 650°C at a speed of 120°C / h, and then keep it warm for 4 hours;

[0047] S2. After S1 is completed, stop the continuous heating of the heating plate 15, so that the raw materials are naturally cooled to 500°C along with the box body 16;

[0048] S3, after completing S2, open the slide plate 13, open the radiator 2, let the raw material fully contact with the air for cooling, so that the temperature is cooled to 210°C;

[0049] S4. After completing S3, turn off the radiator 2, turn on the heating plate 15, and continue heating. After heating the raw material to 240° C., keep it warm for 3 hours, and then cool it to room temperature in the air.

Abstract

The invention relates to the technical field of material annealing, in particular to an annealing device. The annealing device comprises a box body, wherein a box door is hinged to one side of the boxbody, a handle is arranged outside the box door, a base is welded at the bottom of the box body, a control cabinet is fixedly installed on one side of the outer portion of the box body, a temperaturedetector is arranged in the middle of the upper end of the inner side of the box body, heating plates are fixedly arranged on two sides of the interior of the box body, a fixing mechanism is arrangedbetween the box body and the box door, two groups of sliding mechanisms are arranged at the lower end of the inner side of the box body, circular grooves are formed in the middle of the upper end ofa supporting plate, two groups of rotating mechanisms are arranged at the bottoms of the inner sides of the circular grooves, two groups of clamping mechanisms are arranged on the outer side of the upper end of a round plate, and a heat dissipation mechanism is further arranged at the upper end of one side of the box body. The annealing device is stable in structure, convenient to operate and capable of effectively reducing the hardness, and improves the cutting machinability, eliminates the residual stress, stabilizes the size, and reduces the deformation and the crack tendency.

Description

technical field [0001] The invention relates to the technical field of material annealing, in particular to an annealing device and an annealing method. Background technique [0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grain, adjust structure, and eliminate structure defects. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metal materials. Moreover, the purpose of annealing new materials is similar to that of traditional metal annealing. [0003] The existing annealing devices on the market are large in size, complex in operation, difficult to load and unload raw materials, and unable to stably clamp steel pipes, copper wir...
