For the quality of rolled products, a perfect surface quality and tight, close tolerances apart from defined mechanical properties are essential. One key condition is a perfect pass design in the rolling mill. The paper deals with the models for a pass design calculation as well as a calculation of roll force and power demands for the rolling mill. …

In an MPM (multistand pipe mill) and sizing mill two-roll stands arranged alternately at 90° to each other are used. In the MPM the rolls roll against a mandrel bar, i.e. the rolls reduce the wall thickness while retaining a con-stant inside diameter. The outside contour only becomes round in the so-called extractor mill (MPM extrac-

This enhances rolling rigidity and hardness while reducing spare parts wear. • The bevel gearbox of the high-speed wire rod reducing sizing mill employs a "double long shaft" design for greater stability of the bottom support. The input shaft diameter is increased to ∮145mm (compared to 100mm in other enterprises), enhancing rolling force.

The precise and powerful roll pressure unit generates linear loads from 5 to 120 N/mm (P-rolls 90 to 120 N/mm), significantly wider for both low and high roll pressure than traditional mills. Products can be processed in a low roll pressure range (5 to 25 N/mm) for better repeatability. Higher roll pressures can be used for more efficient ...

Another key difference between these two types of equipment is the level of heat generated during the grinding process. Triple roller mills generate less heat compared to bead mills due to the low speed of operation. This is an advantage in applications that require temperature-sensitive products as it helps to maintain the quality of the product.
