Stretch reducing mill. The stretch-reducing mill represents the third main forming step of seamless tube production. The heated hollow is stretched to achieve the final diameter and wall thickness by up to 30 driven roll stands without internal tool through several driven roller stands.

Stretch Reducing Mill; Stretch Reducing Mill. The mother tubes, which have been re-heated and descaled using a water blast, are deformed in a stretch-reducing mill with 28 stands, until they have the final desired diameter and wall thickness. Various controls ensure optimal yield of the mother tube and that the required tolerances are met.

The principle of the stretch reducing process is analyzed and three models of pass design are established. The simulations are done about variables, such as, stress, strain, the stretches between the stands, the size parameters of the steel tube, and the roll force parameters.

Electrical Resistance Welded Tubing (ERW) Hot Stretch Reducing. While a typical ERW mill can produce limited size ranges, PTC Alliance can further reduce products, while preserving the ductility and elasticity. Hot Stretch Reducing is ideal for A106 Seamless and Seamless Boiler tubing.

Understanding Rolling Process in Long Product Rolling Mill Rolls and roll pass design. High tension can stretch reduce the cross section of the bar making shape control very difficult. At the extreme, tension can pull the bar apart, creating a cobble.

Keywords: Metal Working, Tube Shaping, Constitutive Equation, Roll Torque, Analytical Model, Stretch Reducing, Process Control 1. INTRODUCTION The stretch reducing mill (SRM) is a highproductivity process for hot finish-rolling seamless steel tubes of small diameter.

number of passes of the stretch-reducing mill depends on the total size of the reduction and the decrease of the temperature in all the reducing passes. The model design of the stretch-reducing parameters, mainly reductions, stretchings, and temperature, is relatively complex and depends on several mutually related parameters.

In reducing stretch-reducing rolling mill processed pipe passes through the rolling line, on which the feed direction of the pipe located a certain number of rolling stands. In each rolling mill stand rolls installed that in the process of rolling contact with the pipe, respectively, at a certain peripheral segment.

24 stands stretch reducing mill is one of the key equipments on the hot rolling line of seamless tube.It is used to roll the waste pipe after the mill to conduct further rolling of centerless bar with tension.By means of hot rolling, the mill can reduce diameter, reduce wall, equal wall and increase wall.
