If you are looking for customized and cheap clay brick light made in China from a clay brick light factory, Zibo Qunhui Refractory Co.,Ltd is always at your service.
Specifications
1. light weight refractory insulating bricks
2. light weight
3. thermal insulation property
fire clay light weight refractory insulating bricks is a kind of light refractories.Its Al2O3 content is usually above 48%, its density commonly range from 0.4g/cm3 to 1.35g/cm3. It enjoys excellent thermal shock resistance. Light weight high alumina brick is widely used in the construction of furnace lingings. When it is face with fire directly, the temperature shoule below 1350°C.
characteristics of Fire Brick:
Excellent strength at ambient and elevated temperatures
High compressive strength
Every brick ground to precise dimensions
Very low levels of iron and other impurities
Lightweight and energy-efficient
Lower heat storage than denser refractories
Heats quickly and economically to operating temperature
Cools fast to speed periodic operations.
Typical Application:
Glass Industries
Ceramics Industries
Electrolytic Aluminum Industries
Iron & Steel Industries
Non-Ferrous Metals Industries
Power Generation Industries
Package: pallet with thermal shrinkage PE
