In order to study the hot Compact Strip Production (CSP), four-high mill vibration characteristics, and vibration suppression method, the roller system structure stability was analyzed and calculated at first in the paper. And then, the mill stand gap was measured at field and its influence on roll transverse vibration was analyzed. The drum …

In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been fine-tuned to run a specific diameter range, typically at fast speeds (see Figure 1 ). Diameter range is mentioned because a tube mill welds a round product.

Considering the two kinds of nonlinear constraints of rolling mill hydraulic cylinder, spring force and friction force, the vibration model of rolling mill system is established. The amplitude frequency response equations are obtained by using the average method. Comparing the time history curves of vertical vibration displacement of …

Structure of the traditional I-6h rolling mill. As shown in Fig 4, the roll system of the novel X-6h rolling mill is composed of one upper left BUR (ULBUR), …

The calculation of force for a roll system has significant effects on cold rolled thin strip gauge adjustment of a 20-high Sendzimir mill. According to the rolling parameters and rolling plans of a ZR-22BS-42 Sendzimir mill in a silicon steel factory, the contact force and the resultant force of each roll in the roll system were calculated both in the static …

The major components of a rolling mill consist of (i) rolling stand or roll housing which needs a very rigid construction, (ii) roller table conveying system for the …

The components of rolling mill vibration system all are nonlinear, and the performance in nonlinearity is slightly different. Hydraulic system is a classic nonlinear …

a wide range of standard and custom rolling mills for a variety of applications. These rolling mill applications include heavy ingot breakdown, laboratory research, coil to coil …

Medium and heavy plates are important strategic materials, which are widely used in many fields, such as large ships, weapons and armor, large bridges, and super high-rise buildings. However, the traditional control technology cannot meet the high-precision control requirements of the roll gap of the thick plate mill, resulting in errors in the …

mills enables movement of the front roll for Nip-Gap adjustments without any negative e˛ect on the drives which you otherwise would encounter on traditional two-roll mills using connecting gears on the roll shafts. All our two-roll mills except the bench top version are equipped as standard with in˚nite variable speed drives, one for each roll.

1. Two High Rolling Mills. It contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor. The vertical gap between the roll is adjustable. The rolls rotate in opposite directions and are driven by electrical motors.

The control problem of the hot-steel rolling mill is thus formulated in two levels: (i) from to one computes the control inputs and that should be applied to the hot-steel roll mill system so as to assure that the angle of the looper and the tension on the strip will reach the desirable setpoints, (ii) the control inputs and become setpoints ...

‐ Operator defines a "Roll Priority List" indicating the priority associated to each roll to be ground; or ‐ Mill Operator defines a "Mill Schedule List" at mill level; or ‐ Mill Operator sets ranges of acceptable roll diameter. Manual Data Input Mode ‐ Operator selects a list of missions by drag-and-drop actions on software GUI.

from coming down onto the roll surface. The situation in the cold mill differs in regards to cooling the roll bite. In the cold mill the lower temperatures are such that coolant can be applied as close to the roll bite as possible. It should be applied entirely on the roll or on the product. If the coolant is applied such that

Given that the 4-high CVC mill has work roll shifting function, it can use the K-WRS technology to realize similar function of the 6-high UCMW mill . However, the edge drop control capacity of the 6-high UCM rolling mill is obviously insufficient because of the lack of work roll shifting function.
