High-Temperature Bio-soluble Ceramic Fiber Modules

Product Overview

High-Temperature Bio-soluble Ceramic Fiber Modules not only exhibit excellent high-temperature resistance, thermal insulation, and thermal stability but also gradually dissolve and are expelled from the human body in biological environments, complying with EU bio-soluble standards. They serve as an environmentally friendly refractory insulation material, effectively replacing traditional ceramic fiber modules. They are particularly suitable for high-temperature industrial kilns and heat treatment equipment.

Featuring pre-formed structures, compact design, easy installation, and minimal heat loss, this product is widely used in furnace lining upgrades and energy-saving renovation projects across industries such as steel, non-ferrous metallurgy, ceramics, glass, and petrochemicals.

Product Structure and Specifications

(1) Module Structure

Bio-soluble ceramic fiber modules consist of multi-layered folded or stacked Bio-soluble ceramic fiber blankets. They are pre-formed into various sizes and secured with anchors to create an integrated furnace lining structure. During installation, the fibers expand in predetermined directions, tightly filling gaps to enhance the overall sealing and insulation performance of the furnace lining.

(2) Common Specifications

Module Dimensions: 300×300×(100–300) mm

Density Range: 160–220 kg/m³

Temperature Ratings: 1260°C, 1350°C, 1400°C

Anchoring Methods: Y-type, U-type, L-type, anchor bolts, and other options

Module Orientation: Z-type (fibers vertical), X/Y-type (fibers horizontal)

Customized irregular structures and non-standard sizes are available based on customer requirements.

Product Advantages and Features

(1) High Thermal Stability

Maintains excellent volume stability and insulation performance under high-temperature conditions, with minimal degradation or collapse.

(2) Bio-soluble and Eco-friendly

Fibers can be naturally metabolized and expelled by the human body, significantly reducing long-term health risks associated with exposure.

(3) Easy Installation and High Construction Efficiency

Pre-formed to standard dimensions, modules can be directly anchored to furnace shell steel plates without complex secondary processing, reducing installation time by over 30%.

(4) Significant Energy-saving Effect

Low thermal conductivity minimizes heat loss, delivering superior long-term energy efficiency compared to traditional ceramic fiber modules.

(5) Adaptability to Complex Structures

Can be custom-shaped into various profiles to fit irregular furnace bodies and curved surfaces, ensuring tight sealing and extending the overall service life of the lining.

Application Fields

Industrial heat treatment furnaces

Non-ferrous metal smelting furnaces

Petrochemical heating furnaces

Ceramic tunnel kilns and shuttle kilns

Waste incinerators, high-temperature waste-heat boilers

Glass melting furnace roof insulation

Hot-blast stoves, high-temperature pipeline insulation systems

Soluble ceramic fiber modules are widely used in both new furnace installations and energy-saving retrofits of existing furnaces, representing a key choice for the green upgrading of high-temperature equipment.

Installation and Maintenance Guidelines

Clean the furnace shell surface before installation and ensure anchors are securely fixed.

Arrange modules in a staggered pattern to avoid thermal bridging at seams.

After installation, promptly initiate a controlled heating process to remove adsorbed moisture.

Regularly inspect seams for detachment or cracks, replacing modules as necessary.

During furnace downtime, protect modules from moisture and corrosion to extend service life.

FAQ

Q1: What is the difference between soluble ceramic fiber modules and traditional ceramic fiber modules?

A1: The key difference lies in safety and environmental impact. Soluble fibers are harmless to the human body, comply with biosoluble standards, and are more eco‑friendly, making them ideal for industries with stringent safety requirements.

Q2: What is the maximum temperature resistance?

A2: Depending on the grade, the operational temperature range is 1260°C to 1400°C. We recommend selecting a grade based on actual furnace operating conditions.

Q3: Can custom shapes and sizes be provided?

A3: Yes. We support customization of non‑standard sizes and special‑shaped modules based on clients' furnace structure drawings.

Q4: How is lining tightness ensured after installation?

A4: Modules are designed with built‑in expansion space. During installation, they expand in the intended direction to automatically fill gaps, ensuring a seamless lining without thermal bridging.

Q5: Do you provide installation guidance?

A5: Absolutely. We offer installation drawings, on‑site construction videos, and remote technical support. If needed, our engineers can also provide on‑site assistance.
