Type TD and type DSD Wire drawing machines
Eurolls has two families of dry-drawing machines, particularly suitable for the production of wires of low-carbon steel, high-carbon steel, stainless steel and special alloys, using both reduction by die and reduction by cold-rolling. The TD machines are traditional multipass lines with die or cold rolling cassette reduction, with tilted blocks and speed control by means of sensing rolls. Rotation of capstans is obtained through AC Motors, connected by means of gear-boxes. The DSD machines instead are an innovative design and differ from the traditional TD machines mainly because of the use of multi-pole (usually 8 to 32) AC Motors permanent-magnet synchronous type, connected directly to the capstan shafts, therefore eliminating the use of belt transmissions or gear-boxes.
Standard configuration of Eurolls dry-drawing machines includes sturdy, vibration-free, modular steel frame, tilted capstans made of forged steel C50, tempered and induction hardened to 62 HRC, coated on the lower-band in contact with the wire by black ceramic or TC hard facing. Capstan cooling using high-turbulence water flow is even more efficient thanks to our very own patented solutions. It is possible to use rotating or fixed die-boxes, and interchangeable with Eurolls cold-rolling cassettes.
