What is a dual wire intermediate drawing machine with annealer?
It is a wire drawing line that draws two wires at the same time and uses an online annealer to soften the wire before take-up. It is commonly used in copper wire and cable production where stable output and annealed wire quality are required.
What materials can this machine process?
The provided SZ17B/ST2000 configuration is designed for low-oxygen or oxygen-free round copper wire. Aluminum wire or aluminum alloy wire drawing configurations can be customized according to material, wire diameter and production process.
What finished wire sizes can be produced?
According to the supplied specification, the line can produce 2 x 0.30-1.12 mm in dual wire mode and 1 x 0.30-1.60 mm in single wire mode.
What is the maximum mechanical speed?
The maximum mechanical speed is 1800 m/min. Actual production speed depends on wire diameter, material, die schedule, annealing requirement and take-up condition.
Does the line include online annealing?
Yes. The ST2000 annealer uses contact-type triangular short-circuit DC annealing and is suitable for softening copper wire. Annealing requirements for other materials should be confirmed during technical discussion.
What equipment is included in the complete line?
The standard configuration includes SZ17B drawing unit, ST2000 annealer, two K200 tension controllers, two S630 single spoolers, electrical control system, foundation/layout drawing and technical documents.
