ROLL PASS DESIGN OF SECTION MILLS N. V. Litovchenko, B. B. Diomidov, and V. A. gurdyuroova The second chapter gives an account of the general problems of designing a roll pass for a section: compilation of a scheme for the pass with consideration of the entire assortment and type of mill, determination and substantiation

Roll Pass Design Long products are normally rolled in several passes, whose numbers are determined by the ratio of the initial input steel material (square or round billet or bloom) and final cross section of finished product.The cross section area is reduced in each pass and form and size of the steel material being rolled gradually approach to the desired profile.

The geometry and dimensions of the exit cross section, the separation force, roll torques, and the power consumption in each stage are calculated. Comparison of the new roll pass parameters and that of the conventional ones in industry is made to demonstrate the advantages of the new caliber design.

The pass line is a line that runs parallel through the roll partings and passes through the centre of the stock area of each pass at every stand.

Roll wear is amongst the key criteria for devising a rational roll pass design. Rolls in a hot mill have to withstand radial loads up to 12 MN and high temperatures in the range of 900 to 1300 oC. In addition to the obvious need for resistance to breakage, there is the continuing component of roll wear that is critical to the economics of

The primary job of the fin section on any tube or pipe mill is to prepare the edges of the strip (parallel) for welding, and set the body of the tube. The only way this will take place, is if we properly set (work) each and every driven and side pass station in the fin section as per the tooling design

For example, hot rolling with groove rolls has been used for many years. Beynon (1956) presented a typical roll pass design for Tbars, and Brayshaw (1958) showed more examples including special Tsections. Threeroll mills are sometimes applied to Tbar production.

The typical mill layout for such a rolling mill is at Fig 2. The universal roughing and edging mills are reversing multiple pass mills that run in tandem through computerized speed matching. The universal roughing mill is normally a fourroll mill with two driven horizontal rolls and two nondriven vertical rolls.

Another solution for reducing the number of passes in the rolling mills is the employment of automated systems for Roll Pass Design as that proposed by Lambiase and Langella. Other shapes can be coldrolled if the crosssection is relatively uniform and the transverse dimension is relatively small. A tandem mill is a special type of
