For engineers and plant teams choosing or replacing furnace and kiln linings, compare fireclay, high-alumina, silica, and insulating refractories against service temperature, slag chemistry, atmosphere, and thermal cycling. Get a shortlist with trade-offs, questions for suppliers, and a rough lining plan. Share the operating conditions you know; gaps that affect the choice will be flagged.

What it writes
- Refractory material comparison table
- Shortlist by furnace zone
- Supplier questions and specification checklist
How to use it
In your first message, name the lining zone, peak and normal temperatures, atmosphere or slag chemistry, and how the current lining fails. Those specifics make material comparisons more useful.
What you bring
- Peak and operating temperatures
- Process atmosphere and slag chemistry
- Lining zone, failure mode, and cycle pattern
- Know the process and lining zone
A good fit for
- Replacing a kiln lining after repeated thermal-shock damage
- Comparing high-alumina brick options for a slag-contact zone
- Choosing insulation for a furnace with a 1,200°C hot face
Ways to start
A few requests this Agent can handle.
Our gas-fired kiln reaches 1,250°C and cycles twice a day. The lining spalls near the burner. Compare likely refractory options and what conditions I should check.
I need refractory brick for a steel ladle slag line. The slag is basic, peak temperature is 1,600°C, and wear is worst near the tap. What should I compare?
We’re replacing insulation in a heat-treatment furnace with a 1,100°C chamber. Compare ceramic fiber modules and insulating firebrick for heat loss, durability, and installation concerns.
Good to know
This workspace provides text assistance.
- Not a substitute for an engineer’s furnace-safety review
- Recommendations depend on accurate temperatures and process chemistry
- Cannot inspect lining drawings, samples, or installation conditions
