EVRAZ North America Orders Heat-Treatment System
SMS Elotherm received an order from EVRAZ North America for an Elotherm TemperLine™ heat-treatment system for its tubular products plant in Calgary, Alberta (Canada). This unit will increase EVRAZ’s capacity for heat-treated pipe by over 150%. The Elotherm TemperLine is designed for the heat treatment of up to 30 metric tons of OCTG (oil-country tubular goods) per hour. With negligible down-times for changing pipe size or final grade, this 12-MW TemperLine is capable of an overall throughput of more than 200,000 metric tons per year of heat-treated pipes. The induction heating unit is scheduled to go into operation in the fourth quarter of 2014.
“In order to obtain the best metallurgical, mechanical and geometrical results on the processed pipes, the hardening unit is split up into seven different zones, each fully independently powered and controlled,” said Elotherm’s Dr. Guido Opezzo. “This renders it possible to finely adjust the power injected into the pipes and use the final zones as standard final heating zones for ERW pipes or soaking areas when processing seamless pipes and high qualified grades.”
