Working condition analysis (customer medium pain points)
Medium: seawater (high Cl ⁻ chloride ion corrosion)+wet furnace bottom slag solid particles (hard particle erosion wear) solid-liquid mixed slurry
Double destruction:
① Particles: The furnace bottom slag particles have hard edges and corners, and the elbow position is subjected to high-speed impact, resulting in extremely strong wear and tear;
② Seawater: Chloride ions corrode the outer steel substrate, requiring high requirements for the ceramic bonding system of the inner lining. Ordinary epoxy adhesives will be eroded and fail by seawater.

Lining material |
Is it suitable for this operating condition? |
explain |
|
95% alumina ceramic (Al₂O₃) |
✅ Priority – Mainstream |
Resistant to seawater corrosion and wear; the surface mounting process is recommended; ensure that the adhesive used is a seawater-resistant inorganic adhesive or an ocean-grade modified adhesive – conventional epoxy adhesives may delaminate under prolonged seawater exposure. |
|
Reactive sintering of silicon carbide (SiC) |
✅ High-end Selection |
Outperforms alumina in terms of corrosion and wear resistance; offers superior thermal shock resistance; however, the higher cost makes it suitable for applications involving high flow rates or harsh operating conditions. |
|
Cast stone (Basalt) |
❌ Not recommended |
Poor chemical resistance in seawater environments makes the material prone to permeation and bulging. |
|
elastometric lining |
❌ Not recommended |
The rigid furnace bottom slag particles experience severe cutting and wear, resulting in a very short service life. |
