Google Scholar Palani, S., Suresh, K., Thanesh, A., & Muthu, K. (2016). Design and development of billet sawing machine for improving productivity. Indian Journal of Science and Technology.ABSTRACT. Using high-speed rod rolling facilities in the Freiburg laboratory, Lee (Shinokura et al., 1984) carried out a four-pass continuous high-speed rod rolling test to examine the effect of high strain rate, more than 100 (1/s), during rolling on the flow stress and consequently the roll force and torque.

Abstract and Figures. The application of finite element simulation to the problem of roll pass design for round bar rolling is considered. Two …The dimensions of finishing pass differ from the finished profile due to following reasons: Co-efficient of Expansion. Rolling in pass usually takes place between the temperature range from 850 °C-1000 °C, in case of hot rolling of the, rounds and structural profiles, while it is more than 1100 °C, in case of continuous wire rod mill.

Rolling of TMT-32 is same as rolling of plain round 32 mm, except higher metal is required to form lugs and ribs hi finishing pass. The area of finishing pass of TMT should be maintained same as that of plain round-32. Metal sizes of subsequent passes are required to be enhanced. To accommodate the metal size, the plug oval pass of Round-36 ...Since cross-sectional area is reduced progressively at each set of rolls, the rolling stock moves at different speeds at each stage of the rolling mill. A wire rod rolling mill, for example, gradually reduces the cross-sectional area of a starting billet (e.g., 150 mm square, 10-12 meters long) down to a finished rod (as small as 5.0 mm in ...

The classical approach for roll pass design of a wire rod mill employs an iterative technique incorporating spread calculation and rectangular equivalent pass methods. This method comes to its limits in terms of computational efficiency and numerical stability when a complete pass design for a wire rod mill with lots of different final dimensions and materials must be designed.For rounds in finish pass: 1.5 (1) Fittings from oval to round must be 0.3 to 0.7. ... The speed calculation is a function of finishing speed, bar area, roll diameter, tension, and forward slip. ... Although roll pass design for section rolling is usually based on the empirical knowledge of human experts, most of the empirical formulae only ...

The Endless Bar Rolling System (EBROS ®) is used to weld together successive billets while hot in a bar or wire rod mill line, to produce an endless rolling process. Welding is performed by the flash welding method, the properties of the welded joint after rolling are the same as those of the base material, and the joint is a saleable product.Groove angle for intermediate round pass should be 60 0. Groove angle for intermediate finish round pass should be 30 0. Bottom radius for rounds is ½ of dia. Relief radius for rounds is 1/5 th of bottom radius . Relief radius for rounds in finish pass should be 1.5. Fitting from oval to round should be 0.3 to 0.7.

Rolling Mill Pass Design Selection - Hot Rolling Mill - Consideration for Design of Finishing Passes - Ebrary
Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.Rolling speed: 60-100m/s or still higher, achieved with high-speed rolling block (Fig. 1) Billet size: 120mm, 150mm up to 180mm square. Finish size: Dia. 5.5mm or larger round (or possibly also square, etc.) Controlled rolling and cooling: with controlled water-box cooling and controlled air cooling, and draft scheduling for controlled rolling.
