Description
SAF Spare Part: High-Conductivity Copper Water-Cooled Heat Shield

The water-cooled heat shield is an important protective component of the electrode system in submerged arc furnaces (SAF). It forms a cylindrical barrier around the electrode, isolating high-temperature thermal radiation and dust inside the furnace, protecting the electrode holding system (copper shoes, pressure rings, etc.) from burning. It is one of the key spare parts ensuring continuous and stable operation of SAF.

1. Definition

The water-cooled heat shield is a cylindrical device that protects the electrode lower holding system of SAF. It consists of multiple identical sector-shaped units arranged around the electrode to form a cylinder, with closed circulating cooling water channels inside

2. Main Functions
  1. Thermal protection: Blocks high-temperature radiation of 1000-1400℃ from the charge surface to copper shoes and pressure rings, preventing direct flame burning
  2. Dust isolation: Prevents dust generated during production from entering the conductive area, ensuring normal operation between copper shoes and electrodes
  3. Maintenance convenience: Sector unit design allows removal of a single unit for maintenance when copper shoes or pressure rings are damaged
3. Working Environment
Located in the high-temperature zone of the furnace mouth, withstands 1000-1400℃ high-temperature radiation, strong electromagnetic fields, and corrosive flue gas. It is prone to severe deformation or cracking and water leakage during operation, making it one of the most severely stressed components in SAF.

4. Typical Specifications

5. Technical Advantages of Copper Heat Shield
Feature English Description
High thermal conductivity Pure copper thermal conductivity is about 390W/(m·K), more than 25 times that of stainless steel, effectively reducing its own temperature
Magnetically insulated Copper is non-magnetic, avoiding eddy current heating in strong electromagnetic field environments
Better corrosion resistance Copper material has better corrosion resistance to high-temperature flue gas than steel
High recycling value Scrap heat shields have high recycling value, enabling material reuse and trade-in programs, significantly reducing replacement costs

6. Selection Recommendations for Water-Cooled Heat Shield

6.1 Selection by SAF Capacity

SAF Capacity Recommended Type Selection Reason
Small SAF (<16,500 kVA) Steel split-type heat shield Lower investment cost, meets basic protection requirements
Medium SAF (16,500–35,000 kVA) Copper split-type heat shield Good thermal conductivity, extends service life
Large SAF (35,000–81,000 kVA) Copper integral cylindrical / tube-type High smelting intensity, requires greater reliability
Extra‑large SAF (>81,000 kVA) Pure copper upward‑cast integral type Best performance, long service life, high scrap value

6.2 Selection by Material

Material Recommended Scenario Selection Reason
Stainless steel (304/321) Cost‑sensitive, small/medium furnaces, good maintenance access Lower cost, but low thermal conductivity, prone to burn damage and deformation
Pure copper / electrolytic copper (T2) Large SAF, high‑requirement applications, long‑term operation High thermal conductivity, good magnetic isolation, corrosion resistance, long life, high scrap value

6.3 Selection by Structure

Structure Recommended Scenario Selection Reason
Split type Frequent maintenance, need for quick replacement Individual screen units can be removed and replaced separately, easy maintenance
Integral cylindrical Demand for tight sealing and long life Fewer welds, excellent sealing and heat dissipation, long service life
Tube‑type Priority on maintenance efficiency, reduced furnace downtime One‑piece removal, improves maintenance efficiency
