Lightweight insulation bricks are a type of thermal insulation material characterized by high porosity, low bulk density and low thermal conductivity. This brick has a porous structure (usually a porosity of 40% to 85%) and excellent thermal insulation properties, making it suitable for the insulation and heat insulation layers of various industrial furnaces.
How are lightweight insulation bricks classified?
(1) Classification by bulk density
Lightweight insulation bricks: Bulk density between 0.4 and 1.3 g/cm³.
Ultra-lightweight insulation bricks: Bulk density below 0.4 g/cm³.
(2) Classification by use temperature
Low-temperature insulation materials: Use temperatures between 600 and 900°C.
Medium-temperature insulation materials: Use temperatures between 900 and 1200°C.
High-temperature insulation materials: Use temperatures above 1200°C.
(3) Classification based on product shape
Shaped lightweight insulation bricks: including clay insulation bricks, high-alumina insulation bricks, silica insulation bricks and some pure oxide lightweight insulation bricks, etc.
Amorphous lightweight insulation bricks: such as lightweight insulation castables, etc.
What types of lightweight insulation bricks are there?
The most common and commonly used types of lightweight insulation bricks on the market include:
Mullite insulation bricks
Alumina hollow ball bricks
High-alumina polylight insulation bricks
Lightweight clay bricks
What are the sizes of lightweight insulation bricks?
The most common standard size of lightweight insulation bricks (lightweight refractory bricks) is T-3 (230×114×65mm). According to the size specifications, lightweight insulation bricks can be divided into general refractory bricks and special-shaped refractory bricks.
General refractory bricks
General refractory bricks refer to lightweight insulation bricks that can be used in conjunction with other sizes and specifications during construction to complete the construction of the kiln insulation layer. Common general lightweight insulation brick specifications and sizes are as follows:
T3: 230×114×65 mm
G1: 230×150×75 mm
G2: 345×150×75 mm
G3: 230×150/135×75 mm
G4: 345×150/130×75 mm
G5: 230×150/120×75 mm
G6: 345×150/110×75 mm
Lightweight insulation bricks have been widely used in industrial kilns due to their excellent thermal insulation performance, high temperature resistance and lightweight characteristics. Reasonable selection and use of lightweight insulation bricks can significantly improve thermal efficiency, save energy, reduce furnace weight, and optimize the working environment. When selecting lightweight insulation bricks, the appropriate type and specifications should be selected according to the specific use temperature, size requirements and application scenarios to ensure efficient operation and long-term stability of the kiln.
