Steelmaking and metallurgical handling combine scale, coke, ore, sinter and slag with impact, abrasion and rapidly changing temperatures. A liner suitable for a cold burden chute may be unsuitable beside a furnace or where hot material creates thermal shock. The wear map must identify material temperature, contact time, drop height, lump size, vibration and whether molten material, flame or direct radiant heat can reach the lining.
Ceramic wear protection in steel and metallurgical handling
Combination of thermal shock, impact and abrasion from slag, scale and hot burden in furnaces, casting and material handling.
Wear analysis
Ceramic should only be proposed inside its confirmed thermal and chemical envelope. Sliding zones may use alumina; mixed impact zones may justify a rubber-ceramic or tougher ceramic element; direct high-energy impact can require ductile steel or a staged impact bed instead. Attachment, expansion gaps, edge protection and safe containment of fragments are part of the lining design, not installation details to decide later.
Wear mechanisms
Distinguish the loads acting on each part of the process before comparing lining constructions.
Impact from burden and raw-material transfer
Large or irregular feed can load first-impact surfaces, edges and the supporting steel. Drop geometry, feed variability and shell movement shape the damage pattern.
Sliding abrasion in bins, chutes and feeders
Ore, coke, sinter and other solids can create directional wear after impact. The material path, particle range, contact load and support condition should be mapped by zone.
Fine-particle erosion under thermal cycling
Dust-laden flow can attack bends, ducts, collectors and transitions while temperature changes move the steel and joints. Wear and thermal movement must be assessed as a system.
Process data to record
A useful enquiry replaces general labels with the service data that controls wear, installation and inspection.
- 01
Handled material, particle range, maximum lump size, moisture and contamination.
- 02
Throughput, batch or continuous duty, feed variability and blockage or upset events.
- 03
Drop height, impact angle, material trajectory and condition of the first-impact support.
- 04
Normal, peak and shutdown temperatures, rate of change and any direct radiant or hot-particle exposure.
- 05
Vibration, shell deflection, supports, expansion interfaces, cleaning and water ingress.
- 06
Current lining map, failure origin, edge and joint condition, access and outage constraints.
Selection criteria and limits
Use these checkpoints to shortlist a construction without extending any product beyond documented operating limits.
Separate impact, sliding and dust zones
Assign each zone a load path, support condition and attachment concept before selecting a ceramic format.
A hard surface alone cannot compensate for unsupported impact, shell flexure or an exposed leading edge.
Resolve thermal movement
Review joints, attachment, segment size, steel expansion and interfaces across the actual heat-up and cool-down cycle.
Do not infer thermal-shock suitability from ceramic composition or hardness alone.
Define the service boundary
Confirm whether the area sees bulk solids, hot fines, direct flame, liquid metal, chemicals or structural load, and select only within documented limits.
A general wear-ceramic lining must not be assumed suitable for direct molten-metal or flame contact.
Inspection plan
Create a repeatable baseline so future shutdown teams can distinguish deterioration from a different viewing condition.
- 01
Inspect only after the equipment is isolated, cooled and released under the site's safety procedure.
- 02
Map cracks from their origin, noting free edges, cuts, corners, impact centers and any matching shell deformation.
- 03
Check joint opening, displaced pieces, bond-line exposure, thermal staining, corrosion and changes in the material path.
- 04
Compare the same reference zones after similar operating exposure and record any process change that affects interpretation.
Equipment concerned
Focus the wear survey on the components where material flow, impact and operating constraints meet.
- 01Slag chutes and launders
- 02Charging and discharge hoppers
- 03Casting and rolling line components

Answers define a safe starting point; final design still depends on verified process data and the selected system documentation.
Can the same ceramic construction cover impact and hot-dust zones?
It should not be assumed. Impact support, particle trajectory, temperature cycling, joints and attachment impose different requirements. Each zone needs a documented service review.
What temperature information is needed?
Record normal, peak and shutdown temperatures at the lining, the rate and frequency of change, and any direct radiant, flame or hot-particle exposure. The complete system is then checked against exact product data.
What does repeated cracking usually require checking?
Review shell movement, vibration, thermal expansion, support, tile layout, free edges and concentrated impact before attributing the problem to ceramic material alone.
