รายละเอียดเพิ่มเติมAchenbach strip rolling mills reliably produce best strip qualities even at maximum rolling speeds, maximum rolling widths and highest coil weights. Designed either as 6-high or 4-high rolling mills they are always tailored to the specific operation purpose. Special applications, e.g. as bright rolling mills, require the 2-high rolling mill design.
รายละเอียดเพิ่มเติมCluster mill or Sendzimir mill stand – In this rolling mill stand, each of the work rolls is supported by two backing rolls. Cluster mill and Sendzimir mill are used for rolling thin strips of high strength materials and foils [0.0025 mm thick]. The work roll in these mills can be as small as 6 mm diameter – made of tungsten carbide.
รายละเอียดเพิ่มเติมG. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4-high) both roll …
รายละเอียดเพิ่มเติมThe automation of the mill must be designed to suit the short rock drill billets but it must be borne in mind that the full length billets must be rolled without limitations due to optimisation of rock drill bar rolling. A good solution is a 2 stand 3 high roughing mill, with tilting tables, followed by a continuous intermediate and finishing line.
รายละเอียดเพิ่มเติม3: Four high rolling mill: It has a roll stand with four parallel rolls one above the other. The top and the bottom rolls rotate in opposite direction as do the two middle rolls. The two middle are smaller in size than the top and bottom rolls which are called backup rolls for providing the necessary rigidity to the smaller rolls. A four high ...
รายละเอียดเพิ่มเติมA reversing mill stand as considered in this work is outlined in Fig. 1. The plate is deformed in the roll gap by two work rolls. While the lower roll stack is fixed at the mill stand frame, the upper roll stack can be moved by two hydraulic cylinders to adjust the roll gap height.

รายละเอียดเพิ่มเติมThe two backup-rolls reduce the bending deflection of the work-rolls. Additionally, the mills are equipped with devices for bending compensation like hydraulic bending systems and/or specifically shaped rolls (CVC-rolls). These measures shall ensure a plain roll gap and thus a uniform lateral thickness profile of the final product.
