bridle is based on load sharing between the two drives of the bridle Table 3. The advantage of this configuration over the solution with one drive as the speed mas-ter and the other speed-controlled is that the stability is better during acceleration and deceleration and differences in the roll diameter are compensated for at constant speed.

As an example, a Cauffiel 18-high rolling mill is 18-high and 14-high mills. See illustration below showing typical cluster mills.In all cases, one of the main advantages of a cluster mill is the large back up rolls. The back up rolls act as a heat sink because there is a considerable amount of heat energy going into the strip and the work roll.

four-roll bridle is used to control the entry mill tension, filtering all the incoming tension noise from the exit looper with 2 in steady state, 4 of pre-set value. Finally, a fine steering unit centers the incoming strip just before the roll gap of stand 1 with an accuracy of 1 mm. Also, before stand 1 there is a three-roll stabilizer to

Nov 27, 2015 If a mill rolls 80 of the calendar year, that is 365 x 24 x 0.80 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tonshour. If the utilization can be improved by 1 , the available rolling hours is 365 x 24 x 0.81 7096.6, creating 87.6 extra rolling
Z-mill - Wikipedia. A Z-Mill or Sendzimir Mill is a machine for rolling steelUnlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality
In order to achieve the high amounts of tension necessary, a tension leveler utilizes bridle rolls to isolate tension for leveling. The bridle roll design also allows for controlling tension at upstream and downstream coilers. How can we help you Give us a call 855 447-7648 or send us a message here.
