PC Steel Wire Machine Key Equipment Technical Analysis
1. Surface Treatment Equipment
Shelling Machine: Alloy steel rollers use pneumatic cylinder pressure to adjust the bending amount, and the closed design prevents the spread of oxide scale dust.
Electrolytic Pickling Tank: Curved lead electrode plates (500A/16V) produce a hydrogen-oxygen stripping effect, and the sealed structure reduces acid escape.
2. Drawing and Straightening Equipment
Dual-pulling device: Front and rear pullers (including variable-frequency motors) use speed differentials to control tension in real time, preventing wire breakage caused by single-pulling. A medium-frequency induction furnace heats the wire in the middle to improve its ductility.
Multi-roller straightening machine: Eliminates post-drawing stress and ensures straightness ≤1mm/m
3.Heat Treatment System
Induction Heating Power Supply: IGBT medium frequency (500kW/8kHz) for quenching, ultrasonic frequency (200kW/50kHz) for tempering. Temperature Control: Accuracy +-5°C.
Incubator: Preheat for 1 hour to stabilize tempering temperature, with closed-loop control using an infrared thermometer.
4. Tension and Take-up Equipment
Tensioner: Double-layer spring structure provides fine-tuning of the tensioning path to prevent bending and breakage.
Spool Take-up: Utilizes a junction box for dual-end take-up, with a load capacity of 2-3 tons.
