[0028] The use method and advantages of the present invention: The use method of the refined steel wear resistance detection device, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown: when the device is testing the wear resistance of fine steel, the fine steel is first placed on the top of the spline telescopic tube 81, and then the gear ring 84 is rotated counterclockwise, so that the gear ring 84 pulls the spring 86 to wind up, and the ring 85 is driven to rotate counterclockwise under the pulling force of the spring 86, and the L-shaped push plate 87 is pulled counterclockwise by the ring 85, and the lower end of the L-shaped clamping plate 82 is squeezed by the inclined surface of the upper end of the L-shaped push plate 87, so that it deflects and clamps the fine steel; As the spring 86 drives the ring 85 to rotate, the L-shaped slot 88 on the L-shaped push plate 87 squeezes the protrusion 83 to drive the outer sleeve of the spline telescopic tube 81 to move upward, thereby causing the clamped fine steel to move upward and abut against the lower end of the grinding block 7; Then, the fixed motor 2 is started to drive the fixed slide rail 31 and the push plate 39 inside the fixed slide rail 31 to rotate, and the semi-cylinder 315 on the push plate 39 pushes the hollow slide plate 4 to slide back and forth between the two limit slide rails 5, thereby driving the grinding block 7 to slide back and forth on the fine steel, and reciprocatingly rubs the top surface of the fine steel; When the fixed motor 2 cooperates with the push plate 39 and the semi-cylinder 315 to drive the grinding block 7 on the hollow slide plate 4 to reciprocate and rub the top surface of the fine steel, the fixed motor 2 cooperates with the belt to drive the second spring telescopic rod 11 at the lower end of the rotating rod 10 to rotate counterclockwise. When the second spring telescopic rod 11 touches the gear ring 84, it further pushes the gear ring 84 to rotate counterclockwise, ensuring that the gear ring 84 continues to tighten the mainspring 86. Under the action of the winding force of the mainspring 86, the ring 85 continuously applies a counterclockwise rotation force to the L-shaped push plate 87, and the L-shaped slide groove 88 constantly applies an upward thrust to the protrusion 83, thereby ensuring the constant pressure between the grinding block 7 and the fine steel, and ensuring the accuracy of the device in inspecting the wear resistance of the fine steel. If the mainspring 86 between the gear ring 84 and the ring 85 is wound to the maximum contraction value, when the second spring telescopic rod 11 is moved to the gear ring 84 again, the front end of the second spring telescopic rod 11 is compressed and cannot push the gear ring 84 to rotate counterclockwise.

[0029] When the fixed motor 2 drives the grinding block 7 to rub back and forth on the top surface of the refined steel for a certain period of time, the wear resistance of the refined steel can be understood by observing the concavity of the top surface of the grinding block 7.
