Product Description
1. Application Scope and Introduction
The charging car is used in steelmaking workshops with medium-frequency induction furnaces and in cold steel addition workshops for refining furnaces in steel mills. It is installed at the rear end of corresponding equipment, arranged either horizontally or vertically, with 1 to 4 charging cars per furnace.
2. Main Functions
1) Rapidly and centrally load scrap steel into designated equipment, replacing manual or suction cup-based feeding methods, thereby reducing labor intensity and lowering labor costs.
2) The charging car enables centralized feeding, reducing the frequency and duration of feeding operations compared to traditional processes. This significantly improves feeding efficiency, allowing workshops to operate at full capacity and increasing production output.
3) The long-distance transportation capability of the charging car eliminates the spatial constraints caused by conventional grab-type feeding on dust collection systems, thus facilitating effective smoke and dust collection and treatment.
4) Remote control operation of the equipment simplifies and enhances convenience for on-site operations.
3. Equipment Structure and General Layout
3.1 Structural Components
The charging car consists of a frame, movable hopper, travel mechanism, tilting device, hydraulic system, drum unit, and control system.
3.2 Equipment General Layout (Schematic Diagram)
4. Technical Innovations
1) The hopper tilting is driven by dual hydraulic cylinders, providing strong driving force and smooth operation;
2) Hydraulic components are centrally located at the rear of the equipment, away from the loading area, enhancing operational reliability;
3) Remote control operation allows for free shutdown and emergency power cutoff;
4) Compact equipment design saves space and ensures convenient, flexible operation.

6. Hydraulic Control System
6.1 Overview
The hydraulic station serves as the power source for hydraulic transmission, equipped with air cooling. It supplies oil at required flow direction and pressure according to the drive unit's needs, suitable for various machinery where the hydraulic station is separated from the drive unit. By connecting the hydraulic station to the drive unit (cylinder) via hoses, the hydraulic system can perform all specified operations. The lifting function supports stepless switching between fast and slow speeds, while increasing the size of the flow divider/collector valve slightly accelerates the lowering speed.
6.2 Working Principle
The motor drives the oil pump to provide power, which then controls the direction and pressure through hydraulic valves and other drive components (cylinders).
6.3 Technical Parameters
6.3.1 Drive power: 15 kW
6.3.2 Maximum system displacement: 71 ml/r
6.3.3 Oil tank capacity: approx. 200 L
6.3.4 Structural type: Internal horizontal layout
7. Main Structural Description
1) Chassis
Constructed from welded steel sections and plates, it supports the hopper, accommodates the hydraulic station, electrical control system, and counterweight blocks.
2) Moving Hopper
Assembled from steel plates to ensure a smooth, flat interior surface, minimizing friction between scrap metal and the hopper. Reinforced external ribs made of structural steel enhance strength.
3) Transmission Unit
Composed of a motor, reducer, coupling, and wheel assembly, it drives the idler wheels at a controlled speed.
4) Cable Reel Device
Mounted at the front end of the chassis, it automatically winds and unwinds the cable during forward and reverse movement of the feeding car.
5) Hydraulic Circuit System
