Embodiment 1
[0046] In this embodiment, a method for controlling the surface morphology of strip steel is applied to the wet leveling process of a double-frame temper machine, and the method includes:
[0047]According to preset conditions, the target strip steel is controlled to pass through the first work roll on the first frame of the double-frame tempering machine and the second frame of the double-frame tempering machine successively at a speed of 300m / min Continuous rolling of the second work roll; where,
[0048] The roughness of the first work roll is 2.0um, and the roughness of the second work roll is 1.2um;
[0049] The entry tension of the first work roll is less than the tension between the first work roll and the second work roll, the exit tension of the second work roll is less than the entry tension of the first work roll; and,
[0050] The entrance tension of the first work roll is 12 kN, the tension between the first work roll and the second work roll is 15 kN, and the ex...
Embodiment 2
[0054] In this embodiment, a method for controlling the surface morphology of strip steel is applied to the wet leveling process of a double-frame temper machine, and the method includes:
[0055] According to preset conditions, the target strip is controlled to pass through the first work roll on the first frame of the double-frame tempering machine and the second frame of the double-frame tempering machine successively at a speed of 600m / min. Continuous rolling of the second work roll; where,
[0056] The roughness of the first work roll is 4.0um, and the roughness of the second work roll is 3.0um;
[0057] The entrance tension of the first work roll is 30 kN, the tension between the first work roll and the second work roll is 40 kN, and the exit tension of the second work roll is 25 kN.
[0058] Further, in order to further improve the quality of the surface topography, the first elongation of the target steel strip after being rolled by the first stand machine is 0.7 of t...
Embodiment 3
[0061] In this embodiment, a method for controlling the surface morphology of strip steel is applied to the wet leveling process of a double-frame temper machine, and the method includes:
[0062] According to preset conditions, the target strip steel is controlled to pass through the first work roll on the first frame of the double-frame tempering machine and the second frame of the double-frame tempering machine successively at a speed of 500m / min. Continuous rolling of the second work roll; where,
[0063] The roughness of the first work roll is 3.5um, and the roughness of the second work roll is 1.2um;
[0064] The entrance tension of the first work roll is 27 kN, the tension between the first work roll and the second work roll is 38 kN, and the exit tension of the second work roll is 25 kN.
[0065] Further, in order to further improve the quality of the surface topography, the first elongation of the target steel strip after being rolled by the first stand machine is 0....
