The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
a pair of skew rolls, the piercing mill presses the billet against a plug to pierce the billet, and then rolls the billet between rolls and the plug, forming it into a hollow tube of the prescribed outside diameter and wall thickness. During this Mannesmann process, the hollow tube is elongated by a mandrel mill, a plug mill.

Rotary Tube Piercing Rotary tube piercing, also called roll piercing, or the mannesmann process, is a hot forming process that can manufacture long lengths of seamless tube and pipe. Compressive forces applied to a cylinder will create internal stresses at the center. These stresses result in crack propagation.
The tube is rolled passing through each stand while the cylindrical mandrel moves at a constant controlled speed during the whole rolling phase. At the end of FQM rolling, the mandrel returns rapidly through the mill back in the starting position, while the tube is extracted from the mandrel by means of a extracting mill located inline with ...
A tuberolling mill using shortmandrel draw equipment includes a piercing mill. Two piercing mills are used to roll pipe with a diameter exceeding 200–300 mm; the second piercing mill is used to decrease the pipe wall thickness and increase the diameter of the shell. The shortmandrel, or automatic, draw mill is installed after the piercing ...
As an example, a cold drawn tube may have to be drawn 34 times to equal the same amount of work of a pilger mill. Each time a tube is cold drawn, the tube must be cleaned and annealed (softened) before drawing again. For producing very small quantities of tube alloys, cold drawing has the advantage with quick tool changes and low operational ...
In the Mandrel Mill Process, a solid round (billet) is used. It is heated in a rotary hearth heating furnace and then pierced by a piercer. The pierced billet or hollow shell is rolled by a mandrel mill to reduce the outside diameter and wall thickness which forms a multiple length mother tube.
