Jun 18, 2014· Roll pass design is a set of methods for determining the dimensions, shape, number, and type of arrangement of rolling mill passes. Roll pass design also includes the calculation of pressing forces and their distribution on the roll passes.
Application Bar rod mill. Structural mill • HIGH SPEED ST EEL ROLL This is the latest developed roll material .Rolling mill all ove r the world have started using this grade getting wide benefits. Application Bar rod mill (both intermediate finishing stand), Small section like channel angle mill. Hot strip mill.
Abstract: The rolling conditions for heavy sections are very complicated and may create different surface problems (uneven wear, fire cracks, sticking) in various areas of the passes. Additionally the roll pass design influences wear. Rolling loads – especially due to rolling accidents may cause breakages of the barrel or of collars.
Extracting essential roll pass design relations can be done by means of statistical methods providing that the pass geometry is defined in a suitable generic manner. This research will lead to the development and verification of a new method of roll pass design by virtue of statistical analysis.
OBJECTIVE OF ROLL PASS DESIGN Steel sections are generally rolled in several passes, whose num ber is determined by the ratio of initial input material and final cros s section of finished product. The cross section area is reduced in each pass and form and size of .
We have vast experience in the development of section profiles; rationalization and augmentation of the production of different section and continuous structural mill. We can undertake technical evaluation of a rolling mill, its roll pass design and practices and can suggest means to improve rolling practices, roll pass design and mill management,

Nov 27, 2015· The final dimensional quality of the rolled product is determined by the rolling stands within the finishing mill. The dimensional accuracy in the final product depends on many factors including the initial stock dimensions, roll pass sequence, temperature, microstructure, roll surface quality, roll and stand stiffness and the stock/roll friction condition.
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.
As regards "abnormal" rolling conditions which are more or less very "normal" for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll
mill is required. Pass Design The leader sections for the multiple slit rolling process, square, rectangular or round have to be of very close tolerance. This requires: * Correct pass profile in the rolls * Correct roll gap to ensure no overfill * Correct pass alignment between top and bottom rolls * Sound roll neck bearings and positive roll
rolls is called rollpass design. Its goal is to achieve uniform deformation throughout the cross section in each reduction. Fig. rolling mills: Various rolling mill .
The foundation of a successful rolling mill operation is a fine tuned pass design. The pass design is created based on your specific mill layout and product requirements. Quad has improved productivity and quality simply by modifying or replacing existing pass designs.

Jan 08, 2014· Extend the size range of products already rolled on an existing mill. For example, providing a design for 8 mm X 3 rebar on a mill that already rolls 10 mm X 2 rebars. Redesigning passes of an existing product to roll the same cross section out of a different material.
A good rule of thumb is to try to design all roll passes to selffeed even when running coil stock. The mill operator should not have to feed a new coil and "pry" the section into the next pass. *NOTE: If endflare is a concern and a "finish pass" is desired, consider adding two more passes to this ten pass example.
Section Rolling Mill. Rolling mills are facilities that carry out a series of processes including rolling the billets, blooms, slab and beam blanks – extracted from the reheating furnace – into the prescribed size and correcting any bending, cutting them into given lengths, .
