• 4-Hi Rolling Mill Hani Tech

    The 4-hi rolling mill completes this process by working rolls. The work roll includes two kinds of motion: rotating and moving. The former is realized by the main drive of the rolling mill and the latter is used to adjust the reduction and control the deformation degree of the rolling piece, which is realized by the rolling mill screw-down device.
