Brand: ZOUYU

Zirconia Ceramic Fiber Module - High-Temp Furnace Lining

Product Overview

ZOUYU Zirconia ceramic fiber modules are premium-grade insulation units specifically engineered for extreme temperature applications. With a ZrO2 content of 15-17%, these modules achieve a classification temperature of 1430°C and can sustain continuous operation at up to 1350°C, making them ideal for the most demanding industrial furnace environments.

Manufactured using the advanced ISOWOOL production process, each module integrates internal metal fasteners and anchor systems for rapid, secure installation directly to furnace walls, significantly reducing construction time and maintenance costs.

Key Features

ZrO2-enhanced composition for extreme temperature resistance up to 1430°C

FAQ

Frequently Asked Questions

Technical and commercial answers for this product. If your question is not here, our engineers will answer it directly.

Why specify a zirconia module?

+

With 15-17% ZrO₂, the module is classified at 1430°C and rated for continuous service to 1350°C. Zirconia suppresses crystal growth at temperature, so the module resists shrinkage and stays resilient where standard grades would harden and crack.

At what temperature should I move from HA to zirconia modules?

+

Above roughly 1200°C continuous hot-face temperature. HA modules are rated to 1200°C; running them hotter shortens life through accelerated shrinkage.

What density range do zirconia modules use?

+

Zirconia modules are supplied at 60-200 kg/m³. Lower densities reduce heat storage for cyclic kilns; higher densities improve resistance to gas velocity.

What anchoring system is used?

+

Internal metal fasteners in stainless steel or Inconel, chosen to suit furnace temperature and atmosphere. The anchor is embedded in the module body, away from the hot face.
