**Introduction:**
This machine is capable of processing steel bars ranging from Φ5.5mm to Φ12mm at high speeds. The maximum speed reaches up to 180 meters per minute for Φ5.5mm to Φ7mm, while Φ8mm to Φ10mm can be processed at 150 meters per minute (at 580°C heating temperature). For Φ10.5mm to Φ12mm, the speed is up to 130 meters per minute (also at 580°C). It's important to note that temperatures above 580°C may affect the wire speed.
**Machine Summary:**
The system includes dephosphorization equipment, driving and driven rolling mills, medium-frequency heating devices, CNC flying shears, speed measuring devices, automatic steel tilting machines, and balers. It uses ordinary carbon steel as raw material, reducing the diameter, forming, and heat treatment to enhance the grain boundary organization and improve physical properties. The machine automatically sizes, cuts, and bales the products for storage.
**Features:**
1. Utilizes a driving and driven rolling mill structure, combining one-time reduction and forming, offering adjustable speed, easy roller changes, and user-friendly operation.
2. Incorporates on-line heat treatment, control, and quality inspection technologies, enabling automated and high-speed continuous operation.
3. Achieves full automation for both 10M and 12M configurations.
4. Offers a coiled cold rolled ribbed bar production line.
5. Ensures high mechanical performance, exceeding national standards GB13788 and meeting the III-grade hot-rolled steel standard.
**Phosphorus Removal Machine:**
- Features a reducer for easy adjustment, full-enclosed protection, and optimized loading angle for smooth feeding.
- Uses YG8 alloy guide molds and Cr12 alloy guide wheels.
- Function: Removes oxide layers from raw materials, reduces adhesion, protects the rolling ring and medium-frequency device, and improves product surface quality.
- Principle: Gear motor drives the worm, transferring power through the worm gear to rotate the turnplate, guiding the material into an "S" shape.
**Power Unit of Driving and Driven Rolling Mill:**
- Provides rolling power using a variable-frequency motor.
- Features a gear motor with a transformation ratio to drive upper and lower spindles.
- Includes a YVF 132KW three-phase variable-frequency motor, which starts with low frequency and voltage, minimizing starting current and power system impact.
- Couplings with spring dowel pins reduce noise and allow automatic axis center adjustment.
- Universal coupling offers large angle compensation, high transmission efficiency (0.98), and convenient maintenance.
- The reducer is made of hard-tooth surface gears, optimized for strength and durability.
**Rolling Mill Unit – Reducing Mill:**
- Processes raw materials after the finishing mill starts.
- Consists of a base, spindle unit, gear motor, worm gear, and worm.
- The base is cast as a whole, and the spindle unit is easy to dismantle and load.

- Made of forged alloy steel (20CrMo), tempered, quenched, and heat-treated for high strength and flexibility.
- Rolling rings are made of WC alloy, ensuring wear resistance and stability.
- Bearings include four-row cylindrical roller bearings and deep groove ball bearings for efficient force distribution.
**Rolling Part of Driving and Driven Rolling Mill:**
- Adjusts the lower spindle to compact the material and drive it through friction.
- Roller seam adjustment is achieved by adjusting the height of the lower roller or manually rotating the worm.
**Dovetail Slide:**
- Designed with a 3D coordinate system, allowing free spatial orientation of the raw material.
- Guide ram and body are made of 45# steel forging, and guide wheels are treated for high rigidity and abrasion resistance.
**Scramming Device:**
- Protects the equipment by detecting production issues and sending signals to the PLC system to stop the machine immediately.
**Medium-Frequency Heating Equipment:**
- Enhances the extension performance of steel by heating it to a certain temperature below Ac1.
- Features IGBT full solid-state induction modules, energy-saving design, minimal harmonic pollution, and a water recycling system for long-term use without scaling or jamming.
**Speed Measuring Device:**
- Measures the production line speed and product length by compressing the rebar and driving the tachometer wheel.
**Flying Shear:**
- Cuts the rebar according to specified lengths using a servo motor and gear deceleration.
- Features high precision, high torque, and wear-resistant cutting tools with compensation structures for tool longevity.
**Centralized Control Cabinet:**
- Integrates all electrical systems, including rolling mill, medium-frequency, heating, shearing, and steel tilting systems.
