CONDUIT FORMING LINE TUBE MILL
CONTROLS SYSTEM UPGRADE

ABB Direct Torque Control (DTC) AC Drives & Motors Replace Existing DC System

OVERVIEW

A tube mill takes flat continuous strip steel and forms it into continuous round or square tubing using a welded seam. The continuous tubing is cut into specified lengths and sold as-is or formed into other products; electrical conduit and exhaust tubing are two examples. Different size forming rolls in the mill determine the finished diameter of the product and the rolls are changed on a job-by-job basis.

The mill control regulates the speed and/or torque of each forming stand. Each stand is closely matched to the previous and subsequent stands using state-of-the-art, digital AC Direct Torque Control (DTC) drives that help alleviate deformed tubing. To further control the finished product, the operator can speed-trim each stand. When it is interfaced to a high-speed, high-power welder and a programmable flying cut-off, control is handled through the system’s Programmable Logic Controller (PLC). Other mill functions, such as the material accumulator, end welder, and downstream automation interface are also PLC-controlled.

The operator station features industrial oil-tight push buttons, lights and selectors, and a fault indicator that is accessed through a programmable touch screen.
