Product Description
Material Handing System Used for Submerged Arc Furnace
The Material Handing System(MHS) is an important part of metallurgical equipment such as EAF, refining furnace, and submerged arc furnace (SAF), responsible for accurately and efficiently delivering raw materials (scrap, ferroalloys, slag-forming materials, etc.) into the furnace according to process requirements.
Bin Storage & Conveying System: Bins are used to store various raw materials, divided by function into high-level bins, intermediate bins, weighing bins, etc.
| Equipment Name | Specifications | Description |
|---|---|---|
| High‑level Bin | Volume: 10–30 m³ Quantity: based on raw material types (e.g., 15 bins) |
Located at the high charging floor; material flows by gravity. Equipped with ultrasonic level meter (low level alarm typically set at 15%). |
| Weighing Hopper | Volume: 1.0–2.0 m³ Weighing range: 0–2000 kg Quantity: 2–3 units (for different bin groups) |
Uses compression load cells for weighing; accumulates multiple materials. |
| Emergency Hopper | Volume: same as weighing hopper | Used to empty the weighing hopper under abnormal conditions. |
| Intermediate Hopper | Volume: determined by process | Located below the weighing hopper; temporarily stores the batched material before feeding into the furnace. |
Feeding Equipment: Vibratory Feeder,Electromagnetic Vibratory Feeder,Disc Feeder and Screw Feeder.
| Equipment Name | Specifications | Description |
|---|---|---|
| Vibratory Feeder | Feed rate: adjustable Control: high/low speed dual‑speed control (with speed change point) |
Enables fast/slow feeding for higher weighing accuracy. Requires compensation for "drop weight" after stopping. |
| Electromagnetic Vibratory Feeder | Feed particle size: 0–50 mm Control accuracy: ±1‑2% |
No rotating parts, easy maintenance; suitable for granular materials. |
| Disc Feeder | Disc diameter: φ1000–2000 mm | Suitable for sticky materials; provides uniform feed. |
| Screw Feeder | Diameter: φ100–400 mm Length: determined by process |
Suitable for powdery materials; enclosed conveying. |
Conveying Equipment: Belt Conveyor,Bucket Elevator and Pneumatic Conveying System.
| Equipment Name | Specifications | Description |
|---|---|---|
| Belt Conveyor | Belt width: 500–1200 mm Belt speed: 0.8–2.0 m/s Capacity: 50–500 t/h |
Suitable for continuous conveying; allows multi‑point discharge. |
| Bucket Elevator | Lifting height: 10–50 m Capacity: 10–200 t/h |
Vertical lifting of materials; small footprint. |
| Pneumatic Conveying System | Conveying distance: ≤500 m Capacity: 5–50 t/h Air source pressure: 0.4–0.6 MPa |
Enclosed conveying, dust‑free; suitable for powdery materials. |
Furnace Front Charging Equipment: Charging & Stoking Machine is specialized equipment for open and semi-closed submerged arc furnaces, with both charging and stoking functions, enabling uniform distribution, eliminating hanging materials, and reducing crust formation in the furnace.
| Classification | Type | Description |
|---|---|---|
| By Function | Single‑function Charging Machine | Charging only. |
| Stoking Machine | Stoking and leveling only. | |
| Multi‑function Charging & Stoking Machine | Combines charging, stoking, and pushing. | |
| By Travel Mode | Straight Rail Type | Travels on straight rails; commonly used in small/medium‑sized domestic Si‑Fe furnaces (three machines per furnace). |
| Circular Rail Type | Travels on circular rails. | |
| Trackless Free‑moving Type | Tire‑type travel, flexible and maneuverable; widely used in large foreign furnaces (one machine can handle three material surfaces). |
