Mini tube rolling plant

Brazil’s CESVI awards highest automotive rating to Powermax30 The Powerrmax30, a plasma arc metal cut- ting machine from Hypertherm, has received a five-star rating from CESVI Brazil, a mem- ber of the Research Council for Automotive Repairs (RCAR). RCAR is a worldwide organisation whose primary activity is concerned with the engineering aspects of accident repair, safety, and training require- ments associated with motor vehicles. The Powermax30 underwent a battery of tests designed to gauge the unit’s reliability, efficiency, and functionality before receiving the 5-star rating. The unit is claimed to be the first and only plasma arc metal cutting system to achieve 5-star CESVI certification. The Powermax30 has a recommended 6mm cut capacity, although the unit is capable of severing metal twice this thickness. During testing, judges noted several design and performance features thatmake it particularly well suited to automotive applications. Leading features include easy controls, safety interlock, tapered torch for working

EZTM JSM, a leading manufacturer of equipment for metallurgical, blast furnace, mining and cement industry, has developed a high performance, lower energy-intensive, automated plant. The technological process is based on piercing a billet and rolling-off a shell in a 2-high mill with guards followed by a sizing- straightening process in a 3-high screw rolling mill. The plant is defined by high automation of all mechanisms, which, in combination with transfer devices, form a complete processing line. Piercing process hourly rate is 38.3 tons per hour. Rolling-off process hourly rate is 30.7 tons per hour. Piercing maximum time is 18 seconds. Auxiliary operations time is 10 seconds. The section is handled by a team of eight people per shift. It is possible to perform both processes in the same mill after single heating by returning the pierced shell to the entering side and simultaneously substituting a piercing mandrel with a rolling one.

Sizing of the billet by diameter is in the 3-high screw rolling mill under 12° feed angle and diameter reduction up to 5%. It allows combining sizing and straightening operations. The mini tube rolling plant has been installed at Vyksa Steel Works, JSC.
