Floating bead lightweight insulation brick is a type of thermal insulation refractory brick, which is made from floating beads as the main raw material.
Floating beads are aluminum silicate glass hollow beads floated from fly ash of thermal power plant. It is lightweight, thin walled, hollow, with a smooth surface, high temperature resistance, and good insulation performance.
By utilizing the excellent properties of floating beads, lightweight thermal insulation refractory materials with excellent insulation performance can be manufactured.
The commonly used size is T3: 230 * 114 * 65mm

Characteristics
Floating bead lightweight insulation bricks have the advantages of high porosity, low bulk density, and good insulation performance.
It is widely used as an insulation and filling material for the space between refractory bricks and ketone bodies in various industrial kilns to reduce heat loss and achieve high energy utilization efficiency.
Floating bead lightweight insulation bricks are used in industrial kilns and high-temperature machinery equipment in industries such as metallurgy, mechanical equipment, chemical plants, crude oil, decorative building materials, light industry, and power engineering. They can generally be environmentally friendly and energy-saving by 15% to 40%, making them a good new type of lightweight insulation material.
Application field of Floating bead lightweight insulation brick
Suitable for blast furnaces, hot air furnaces, carbon calciners, carbon calciners, coke ovens, steel drums, casting refra, boilers, cement kilns, glass kilns, and various kiln linings and thermal equipment.
