This simulator calculates the rolling loads and roll deflection of cluster rolling mills; a 4-high mill, a 6Hi X type mill and a 10Hi X type mill. Figure 1 shows the mills used for calculation. The rolling mills have the backup rolls (BUR), intermediate rolls (IMR) and work rolls (WR) of the same size and the same materials. These components
roll force and torque in the hot rolling process. As an improvement, Poliak, Shim, Kim, and Choo (1998) examined a proposed linear regression model to predict the roll force in hot plate rolling. Lee and Lee (2002) proposed a long-term learning method using neural network to improve the accuracy of rolling-force prediction in hot rolling mill ...
Roll Force load cells PFVL141. The Millmate Roll Force load cells act as integral parts of the mill stand. The rocksolid Pressductor ® load cell design in combination with the intelligent, reliable communication functions are crucial keys to true roll force measurement.
Inter World was founded in 1971 as a steel rolling mill company producing strip-plates. Our first steel plant was situated in North Jakarta, occupied 4.6 hectares of land. In 1975 Inter World Steel built a second rolling mill line to produce Indonesia's first equal angle bars.
A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike 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.
Front tensions are applied and controlled by the take-up reel of a rolling mill (see Fig. 13.11 on page 326). The greater the torque to this reel, the greater the front tension. Back tension is applied by the pay-off reel of the rolling mill, whereby increasing the brake force on .
Principle of Four Rolls Rolling Mill. The roll system of four rolls rolling mill consists of two supporting rolls and two working rolls. The pressing force from cylinder or mechanical system will be transmitted through bearing stand, supporting roll, working roll and finally act on the product during operation.
Nov 27, 2015· Understanding Rolling Process in Long Product Rolling Mill ... Calculation of roll force is important because calculation of torque and power in a rolling mill is based on calculation of roll force. Accurate prediction of roll force for grooved rolling is considerably more difficult than predicting the geometry of the rolling stock.
Two Roll Mill Factories In Indonesia Sebestu. China two roll mill, china two roll mill manufacturers and.A wide variety of two roll mill options are available to you, such as free samples, paid samples.There are 5,987 two roll mill suppliers, mainly located in asia.The top supplying country or region is china, which supply 100 of two roll mill.
ROLLING MILL ROLLING FORCES ... is the roll force in N, is the length of the roll in mm, is the elastic modulus in Pa, is the moment of inertia, is the shear modulus in Pa and is the cross sectional area in mm2 Rowe (1977) calculated the maximum deflection as; is the half of the bearing length in mm, is the diameter of the roll in mm and is ...
F. Ďurovský et al. Computation of Rolling Stand Parameters by Genetic Algorithm – 60 – setting too. This type of model is often called torque-force model. The model computes friction coefficient, steel hardening, roll force and torque according to real data measured on the mill. The main identified values are friction and steel hardening.
A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.
is unloaded roll gap; F 0 is rolling force; M is the mill stiffness or mill modulus. The strip thickness reference has to be created first during the lock-on process by calculating the average values of the actual roll gap and the actual rolling force. According to the spring equation, the strip thickness reference is shown in Eq. (2),
2. The energy required to over come frictional force in bearings. 3. The energy lost in power transmission system. 4. The energy lost in the form of electrical losses in the motor etc., Torque and Power in Cold Rolling *Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip
Feb 21, 2019· In this video I have discussed about the formulas related to rolling mill such as draft, elongation, reduction, spread, contact angle, bite angle, and many more. Tags:- Draft, elongation, bar ...
Roll Force Measurement A Millmate roll force system will help you achieve correct roll gap settings, true force distribution from operator side to drive side of your mill and supervision of the backup bearings and roll eccentricity.

20-High Mills. Sendzimir's 20-High mills are unique in that they have a small, chockless work roll and a cluster roll configuration supported by the Backing Assemblies. The cluster configuration transmits the roll separating force from the work rolls to the mill housing.
Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section, ingot is moved to the rolling mill, where it is rolled into one of three, The roll force in flat rolling can be estimated from the formula 59 (For a frictionless situation; however, an estimate of the actual roll force, .
Roll Force & Special Cylinders. ... Roll Force Cylinders / AGC Cylinders for Cold Rolling Mills: Roll Force Cylinders are specially built Hydraulic Cylinders which are used in Cold Rolling Mills in Steel Industries. Typically these Cylinders are encapsulated in the Mill Housing. These Cylinders are used in pairs to hold the Work roles in ...
The maximum possible draft in a rolling operation depends on which of the following parameters (two correct answers): (a) coefficient of friction between roll and work, (b) roll diameter, (c) roll velocity, (d) stock thickness, (e) strain, and (f) strength coefficient of the work metal?
