Medium Density Calcium Silicate Board in Aluminum Casting Insulation

Medium density calcium silicate board is a high-performance thermal insulation board widely used in the aluminum casting industry. Designed to withstand continuous high temperatures while providing excellent thermal insulation, calcium silicate board helps improve production efficiency, reduce energy consumption, and extend the service life of aluminum processing equipment.

As a trusted calcium silicate board supplier, we provide premium calcium silicate insulation solutions for aluminum melting, holding, and casting operations worldwide.

Why Use Medium Density Calcium Silicate Board in Aluminum Casting?

Aluminum casting involves continuous exposure to elevated temperatures, making efficient insulation essential for maintaining process stability and reducing heat loss. Medium density calcium silicate board offers an ideal balance of thermal performance, mechanical strength, and lightweight construction.

Key Features

• Excellent thermal insulation performance

• Low thermal conductivity

• Continuous service temperature up to 650°C

• High dimensional stability

• Moderate compressive strength

• Easy machining and installation

• Moisture and corrosion resistance

• Non-combustible fire resistant insulation board

• Asbestos-free and environmentally friendly

These characteristics make calcium silicate insulation a reliable choice for aluminum foundries and casting plants.

Applications in Aluminum Casting Insulation

1. Aluminum Melting Furnaces

Medium density calcium silicate board is commonly installed as a backup insulation layer in aluminum melting furnaces. It minimizes heat loss through the furnace shell, improves fuel efficiency, and helps maintain stable melting temperatures.

2. Holding Furnaces

Holding furnaces require consistent temperatures to keep molten aluminum in a liquid state before casting. Calcium silicate board reduces temperature fluctuations, lowers energy consumption, and enhances overall production efficiency.

3. Molten Aluminum Transfer Launders

Transfer launders transport molten aluminum from melting furnaces to casting stations. Calcium silicate insulation helps maintain molten metal temperature during transfer, reducing heat loss and improving casting quality.

4. Casting Machines

In continuous casting and billet casting systems, medium density calcium silicate board is used to insulate equipment structures, protecting mechanical components from excessive heat and improving operational reliability.

5. Hot Metal Transfer Equipment

The board is also suitable for insulating:

• Transfer ladles

• Launder covers

• Distribution boxes

• Molten metal channels

• Auxiliary heating equipment

Its lightweight structure makes installation and maintenance more efficient.

Benefits of Calcium Silicate Board for Aluminum Casting

Improved Energy Efficiency

The low thermal conductivity of medium density calcium silicate board significantly reduces heat loss, lowering fuel or electricity consumption.

Better Temperature Control

Reliable calcium silicate insulation helps maintain stable temperatures throughout the aluminum casting process, contributing to improved casting quality and reduced metal loss.

Longer Equipment Service Life

By lowering external shell temperatures and reducing thermal stress, calcium silicate board helps extend the lifespan of furnaces and casting equipment.

Enhanced Workplace Safety

As a fire resistant insulation board, it lowers equipment surface temperatures, creating a safer working environment for operators.

Easy Fabrication and Installation

Medium density boards are easy to cut, machine, and install, allowing quick replacement during maintenance shutdowns.
