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 …...flow. So, the design of the roll groove geometry and the roll pass sequence are important aspect to be assessed. The pre-diction of the load and torque with different groove designs plays an important role in order to improve the draft during rolling. The roll grooves in a roller and the roll pass sequence in a hot rolling mill are usually ...

At this design stage, the mill is designed with optimal pass schedule, roll diameters, mill type, mill window, and mill housing. Roll profiles are estimated at the design stage and optimized at ...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 …

Whether it is appropriate to select have a decisive impact to the productivity and output of rolling mills, quality, consumption index, and …...In shape rolling manufacture, a work piece will often experience different amounts of reduction in different areas of its cross section. One of the goals of roll pass design is to properly design a series of reductions in such a …

The above researches on roll pass or flower design are mainly for conventional roll forming processes. In conventional roll-forming processes, a metal strip is gradually bent into desired shape by using contoured vertical and horizontal rolls mounted on roll stands, as shown in Fig. 1 ( Schuler, 1996).The formed strip at each stand is shaped definitely by the …...The fin-pass mill is a very important mill followed by FFX forming mill to create suitable welding conditions. NAKATA's system provides the best roll shapes and positions supported by FEM analysis. In addition, our proprietary roll change design, ""Quick Change System,"" dramatically reduces workers' workload and contributes for improved ...

A roll pass design for the sets of rolls of a non-mandrel type multiple-stand pipe reducing mill, each set of rolls having three rolls. In order to improve the roll pass design so that the flow of material in the pipe is acted upon locally in such a way that the occurrence of local thickening of the pipe wall at critical points along the circumference of the pipe during …...It is a consultancy firm formed by a highly experienced and technologically sound professional, who has worked in the field of rolling mills for over 35 years in SAIL, Bhilai and was trained in roll pass design by Russian technologists.We have vast experience in the development of section profiles; rationalization and augmentation of the production of different section and continuous ...

Upcoming Course: Roll Pass Design and Mill Operation Schweitzer Engineering and Rolling Technology, is offering a four-day Roll Pass and Mill Operations training course. During this time we will cover the basics of metal deformation, the rolling of steel, and Roll Pass Design concepts...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

Rolls and roll pass design. Rolls are the tools of the rolling mill and are the costliest consumable in a rolling mill. The way the rolls are used to …...Bar and Section Mills ... Danieli multi-strand slit rolling technology is a combination of a special roll pass design and guide equipment to shape and longitudinally separate the incoming billet into 2, 3, 4 or 5 individual strands. These are then rolled together (as one bar) down to the finished size in the finishing mill stands ...

Do a progressive set up. This means jog the material through the first driven breakdown, through the first 1-2 side roll pass, (if your mill configuration has side passes) and into the second driven breakdown, then stop. Many firms jog the material all the way through the entire mill before starting any set up checks...MECON has been a pioneer in the field of consultancy, design, engineering, manufacturing and supply of Rolling Mills and Processing Lines. For over three decades MECON has designed, engineered, supplied and commissioned many hot and cold mills ranging medium to large capacities. Mecon is also assisting in major investment decisions in the steel ...

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, …...Detailed Rolling Mill Process Engineering – Product Trace ... Product Trace, Roll Pass Design, Guiding, and other elements. Roll Pass Design is a synonymus of product tracing in Hot Rolling of steel sections, shapes or profiles, with a high level of detail, that can vary depnding on installations and content of design in terms of revision, adjustement or whole design.

Flat rolling of plates and sheets is essentially a plain-strain compression. f1.2. Roll Pass design for steel The cross sectional area is reduced in each pass and the form and size of the stock gradually approach the desired profile. Here the thickness of the metal being rolled is reduced in each pass by decreasing the distance between the rolls...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 ...
