Mar 27, 2003· The 10-pass example should be fine if you're running non-notched, postcut mild steel. If the section is notched, precut, or high-strength material, you'll need more passes to achieve desired results. Additional passes allow the material to flow through the mill with less strain. Design the Layout and Roll Tooling

mill is required. Pass Design The leader sections for the multiple slit rolling pro-cess, e.g. 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

Mill, motor and the whole process of roll pass design. Roll pass design is a set of methods for determining the dimensions, shape, number, and type of arrangement of rolling mill passes. Development of a rational roll pass design for a rolling mill using performance criteria. rolling mill pass design pdf

It is in the vertical forming driven fin pass rolls that the tube is prepared for welding. The correct roll design will consider the welder type as well as the physical and metallurgical properties of the product. Some issues addressed in fin roll design are as follows: Strip Edge Conditioning:

Roll Pass Design for Round Bars G. Perotti (I), N. Kapaj; Dipartimento di Tecnologia e Sistemi di Produzione, Politecnico di Torino/ltaly Received on January 8,1990 In the paper a general computer approach strategy concerning the roll pass design for round bars is presented.

Mar 10, 2009· Pass design for channel section in rolling mill? ... The bar is almost completely enclosed by the top roll in a "closed pass" sequence of grooves and the thickness of the web and flanges is ...

A new technique is developed to analyze the roll pass design of a section rolling mill. Metal forming nonuniformity and efficiency coefficients, which determine the degree of working of a metal microstructure in rolling of section bars, are used as performance criteria. The system of roll passes intended for the production of a round bar 28 mm in diameter is used as an example to analyze ...

Hot Rolling Long State-of-the-art solutions for bar, rod, sections and rails Primetals Technologies has a complete portfolio of solutions for bar, wire rod, section and rail, and non-ferrous mills.

HOME>PRODUCTS>Mill section >Fin-pass Mill. The mill is systematically designed by FEM analysis from breakdown to fin-pass and sizing. The mill section is equipped with our proprietary technologies to produce the best tube/pipe quality. The fin-pass mill is a very important mill followed by FFX forming mill to create suitable welding conditions.

This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. The final chapter explains the purpose of roll pass design to ensure the maximum output at minimum cost as well as to reduce the roll wear to a minimum.

Mar 09, 2018· Watch how an optimum roll pass design leads to the distribution of loads across rolls, ensuring better rolling quality and reduction in specific power consumption. United Nations Development ...

With over 30 years experience with hot rolling mills and OEMs of rolling mill equipment, we have the know-how to solve your problems and develop new products for you. We pride ourselves for developing the highest quality roll pass design to ferrous and non-ferrous hot rolling mills for production of the most challenging sections.

Roll Pass Designs projects typically follow the following timeline: Development of detailed groove drawings, roll barrel layouts, roll stress calculations, rolling power, torque and separating force predictions, and roller set-up sheets. Design review and training sessions with mill personnel

This can be achieved by enhancing the design approach or by developing new rolling passes that allow the production of high cross-section reductions such as with the slit roll pass. However, in ...

Overall scope of supply: • Plant and mill design • New mill equipment • Refurbish existing equipment • New automation system • Roll pass design • Supervision, commissioning and start up Russula designed the mill to roll bars and sections. The new rolling line at Dojran Steel has 18 new housingless stands in an H/V arrangement ...

The analysis of two roll pass design options of ten roughing stands atOJSC "MMK" 370 rolling mill has been performed. The usage of a new form of the roll grooves will allow achieving higher durability of the rolls. Lesser rolls consumption will allow saving up to 800K rubles annually. More uniform load distribution by the stands will reduce the possibility of main mill lines equipment ...

This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. The final chapter explains the purpose of roll pass design to ensure the maximum output at minimum cost as well as to reduce the roll wear to a minimum.

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.

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.
