High Alumina Brick Introduction:

Produced with unique advanced technology, the clay and high alumina heating insulating bricks possess characteristics of high crush strength resistance and good thermal shock stability. The bricks can reduce heat capacity of kiln walls and promote heat efficiency of kilns. Clay and high alumina bricks product is applicable for constructing industrial kilns and inner lining of kilns.

The Al2O3 content of high alumina lightweight insulating brick is more than 48%, which is mainly composed of mullite and glass phase or corundum. The volume density was 0.4-1.35g/cm3. The porosity is 66% ~ 73%, the compressive strength is 1-8mpa, the fire resistance temperature is 1600 ℃, and the thermal shock resistance is good.

The difference between lightweight high alumina bricks and heavy-weight high alumina bricks:

Lightweight high alumina bricks, commonly known as insulating refractory bricks, are also known as insulating refractory bricks. First of all, literally, the weight of lightweight high-alumina bricks and heavy-weight high-alumina bricks are completely different products. Lightweight high alumina bricks, also known as thermal insulation high alumina bricks, have the basic purpose of heat insulation and heat preservation. In normal use, it does not directly contact the temperature of the kiln. It is a refractory brick product close to the furnace wall, which has the function of heat insulation and heat preservation.

Heavy high aluminum bricks, also known as high aluminum bricks, are many times heavier than light high aluminum bricks. They are not used for insulation but more importantly for fire resistance during use. During use, it is in direct contact with the flame in the kiln, so the heavy-duty high-alumina brick Tongtang has the function of high temperature resistance. The high-alumina clinker is selected to be combined with refractory clay. burnt. High aluminum bricks are divided into three grades according to the aluminum content. By adjusting the ratio of high aluminum clay and bonding clay, the aluminum content and high temperature resistance of high aluminum bricks can be guaranteed to meet different use conditions and requirements.

High Alumina Bricks Advantages:

1. High temperature strength;
2. Good insulation performance;
3. Resistant to various atmosphere corrosion;
4. The energy saving effect is remarkable;
5. Excellent thermal shock stability.

High Alumina Bricks Usage:

high aluminum light brick has reached the international similar products of various technical indicators, is the current industrial kiln design must be a new material. High Alumina Bricks are widely used in the furnace lining (not eroded by solution) and insulation layer in metallurgy, machinery, ceramics and chemical industry. It is an ideal energy-saving product. Its service temperature is under 1350℃.
