Abstract

The invention discloses a hydraulic control device for adjusting the roll balance speed of a continuous pipe rolling mill, comprising: a reversing structure, the two ends of the reversing structure are respectively connected to a hydraulic oil circuit and a hydraulic cylinder, and the reversing structure can be remotely controlled; A throttling structure, the throttling structure is connected between the reversing structure and the hydraulic cylinder, and the throttling structure can be controlled remotely. The beneficial effect of the present invention is that, compared with the prior art, the present invention not only realizes all the functions of the prior art without adding hydraulic components, but also can remotely control the reversing structure and the throttling structure , so as to realize the reversing and speed adjustment through remote control, without on-site operation in the actual operation process, reducing the steps of climbing up and down, thereby reducing unsafe factors, reducing adjustment cycles, reducing labor, and greatly improving work efficiency. This makes the adjustment process safer, more humane, and more in line with the needs of fast-paced modern production.

Description

technical field

[0001] The invention relates to a hydraulic control system of a steel rolling machine, in particular to a hydraulic control device for adjusting the roll balance speed of a continuous pipe mill. Background technique

[0002] Steel rolling machinery and equipment, especially the five-stand three-roller continuous pipe mill and the air reducer in the continuous pipe rolling unit, each set of rolls is controlled by a balance hydraulic cylinder. The balance state is the balance locked state. During the process, all rolls are in a balanced state. Each balance hydraulic cylinder is equipped with a displacement sensor to determine the position of the piston rod. The head of the piston rod is inserted into the T-shaped groove of the roll bearing seat. Running away from the direction of the pass line. This adjustment process is controlled by the hydraulic system.

[0003] The five-stand three-roll continuous rolling mill has five sets of continuous rolling stands, ...
