| Component | Material & Specification |
|---|---|
| Cover Shell | Welded structure of Q345R low-alloy steel plate (thickness 20–40mm) or stainless steel 304; corrosion-resistant and high-strength. |
| Cooling Water Jacket | Integrated or modular water jacket design; inner cavity is divided into multiple independent flow channels to ensure uniform water distribution and no dead zones. |
| Electrode Bushing | Chrome-copper alloy (CuCrZr) bushings installed in electrode holes; high conductivity and thermal conductivity, with its own independent cooling branch to prevent overheating at the electrode contact area. |
| Flange Connection | Equipped with sealing flanges at the water inlet/outlet and electrode bushings; uses high-temperature-resistant rubber gaskets to ensure zero water leakage. |
| Reinforcement Structure | Internal steel rib reinforcement to improve mechanical strength and resist deformation under high-temperature and pressure loads. |
| Access Holes | Reserved observation holes, sampling holes, and oxygen lance holes to meet on-site smelting operation needs. |
| EAF Capacity | Cover Diameter | Electrode Hole Diameter | Cover Thickness | Weight |
|---|---|---|---|---|

| Total Water Flow Rate | 80–300 L/min (proportional to furnace capacity: 15–20 L/min per 10t EAF) |
| Cooling Water Quality | Conductivity ≤ 50 μS/cm; pH 6.5–8.5; deionized water recommended to prevent scaling |
| Temperature Rise of Cooling Water | ≤ 15 K (inlet temp ≤ 35℃, outlet temp ≤ 50℃) |
| Sealing Performance | No leakage under 1.2× working pressure; pressure test duration ≥ 30 min |
| Parameter | Specification |
|---|---|
| Maximum Operating Temperature | ≤ 1200℃ (surface temperature under furnace fire zone) |
| Temperature Rise Limit | ≤ 40 K (cover surface relative to ambient temperature) |
| Mechanical Strength | Tensile strength ≥ 350 MPa; withstands furnace pressure fluctuation of ±0.05 MPa |
| Thermal Shock Resistance | Resists 1000℃ rapid cooling/heating cycles without cracking or deformation |
| Service Life | ≥ 12,000 furnace charges (under standard operating conditions) |
| Component | Material Grade | Key Performance Indicators |
|---|---|---|
| Cover Shell | Q345R/304 SS | Yield strength ≥ 345 MPa; corrosion resistance rating ≥ 9 (salt spray test 1000h) |
| Electrode Bushing | CuCrZr | Electrical conductivity ≥ 48 MS/m; thermal conductivity ≥ 320 W/(m·K) |
| Sealing Gasket | High-temperature silicone rubber | Operating temp range: -40℃ to 300℃; compression set ≤ 15% |
