T echnology U pdate EZTM tube rolling plants designed for greater flexibility in manufacturing

EZTM JSC has started the detailed design of a new generation of tube- rolling plants. The principle of Efficiently Fragmented Technological Process (EFTP) forms the basis of the project. The essence of the EFTP principle is that the certain technological process is divided into smaller subprocesses which areused(likeontheprincipleofconstructor LEGO) for flexible developing of different manufacturing processes depending on market requirements to the finished products. The use of this principle at designing of the tube-rolling plant allowed getting three tube rolling technological schemes through using one and the same generally accepted contents of the equipment. Such decision allows providing the production of small and large batches of tubes of wide range of product sizes and grades with minimum expenses for resetting of equipment. The 7-stand continuous mill of new generation with MPM Quattro technology will be used as an elongator. 8-sided wall reduction is performed on the long retained mandrel of MPM Quattro mill (of the 3-high mill – 6-sided wall reduction, of the classic 2-high MPM mill – 4-sided one) Such decision allowed: • providing friction conditions at the outer tube surface similar to three-high scheme; • reducing to minimum the friction processes at the inner tube surface at the mandrel extracting by implementing the technology of increasing of tube cross-section perimeter as compared to mandrel section perimeter, similarly to MPM mill technology (the use of such technology in a three-high mill is impossible); • decreasing the transverse thickness variation of the produced tubes (the technology has the potential to reach

the thickness variation parameter up to the value of ±4%). The distinctive feature of the new MPM Quattro technology is that it can be applied for both building new tube-

rolling plants with continuous mill and retrofitting of existing MPM mills.
