Checker brick is a kind of refractory brick that can withstand 1740-1780℃. It can be used in hot blast stoves, glass kilns, and regenerators of coke ovens. Compared with other refractory bricks, it has a strong heat exchange capacity, large heat storage area, reduced energy consumption, volume stability, and other features.
- Types: Clay, High-alumina, Mullite, Silica, Sillimanite, etc;
- Holes: 7/19/31/37/65/others;
- Delivery: 15-30 Working Days;
- Price: Low Ex-factory Price;
Types of Checker Brick
According to the numbers of holes, chequer bricks have the following types:
- 7-hole bricks;
- 19-hole bricks;
- 31-hole brick;
- 37-hole bricks.
According to the components, chequer bricks have several types:
- Clay checker bricks;
- High-alumina checker bricks;
- Mullite checker bricks;
- Silica checker bricks;
- Sillimanite bricks;
Characteristics of Chequer Bricks
Strong Heat Exchange Capacity
This kind of refractory bricks China has a strong heat exchange capacity. This means that it has good thermal conductivity. When it is used for the regenerator of coke ovens, it contributes to rapidly making cold air turn into hot air.
Large Heat Storage Area
Chequer bricks have a lot of holes. These holes increase the contact area between bricks and hot air. So they can rapidly store the heat and transfer the heat. In a regenerative chamber, chequer brick has a small resistance force that can smooth ventilation.
Good Creep Resistance
Good creep resistance contributes to keeping a stable volume of high-temperature equipment in high-temperature situations. Besides, these bricks usually are hexagons. It can greatly increase the stability of checker bricks.
Applications of Checker Brick
Chequer bricks are usually used in hot blast stoves, glass kilns, regenerators of coke ovens, electric arc furnaces, induction furnaces, AOD furnaces, VOD furnaces, thermal technology equipment, etc.
It is worth to noting that it usually uses clay checker brisks in hot blast stoves, when the hot air is less than 900℃. When the hot air is more than 900℃, it usually uses high-alumina checker brick, mullite checker brick, silica checker brick, and sillimanite refractory bricks.
