Description

Technical Field

[0001] The utility model relates to the technical field of alloy structural steel preparation, in particular to a device for eliminating mixed crystal defects of alloy structural steel. Background Art

[0002] Before quenching, when alloy structural steel is heat treated, the steel is usually heated to the austenitizing temperature. At this stage, if the heating is uneven or the temperature control is not accurate, the mixed grain phenomenon may be aggravated. The rapid cooling during quenching causes the austenite to transform into other hard phases such as martensite. This transformation process can reduce the adverse effects of uneven grain size.

[0037] The working principle of this utility model:

[0038] Before quenching the alloy steel, the heat-treated alloy steel is transferred between the first clamping plate 107 and the second clamping plate 109. The cylinder 108 pushes the second clamping plate 109 close to the alloy steel and clamps it with the first clamping plate 107. Then, according to the performance of the alloy steel, the quenching medium in the liquid storage tank 204 on one side is used, and the knob 207 on the same side is rotated so that the inner wall opening of the ball valve 208 is aligned with the delivery pipe 202. Then, the liquid pump 203 is started to push the heat conduction from the liquid storage tank 204 through the delivery pipe 202 to the inside of the curved plate 205. When the hydraulic pressure pushes the push plate 213 and compresses the spring 212, the push plate 213 descends to the inside of the nozzle 209, so that the upper passage 214 is connected to the quenching medium, and the lower passage 215 is aligned with the upper passage 214, so that the quenching medium is sprayed along the upper passage 214 and the lower passage 215, and the accumulated liquid in the curved plate 205 is discharged.

[0039] Secondly, push the push rod 105 to send the slide 104 under the curved plate 205, start the motor 2 106 to drive the clamp 107 to rotate, thereby driving the alloy steel to rotate when being sprayed, and the quenched medium falls into the liquid guide plate 112, then falls on the side of the partition 111 along the liquid guide port 114, and is finally output through the drain port. In addition, by starting the motor 103, the rotary valve 113 can be driven to rotate, so that the lower end of the liquid guide port 114 is aligned with different sides of the partition 111, thereby realizing the recovery and classification of the liquid guide medium.

However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
