Hanger refractory bricks play a skeleton role in refractory castables. hanger refractory bricks also have a name called anchor bricks.
There are several products that play the role of skeleton in refractory castables: one is hanger refractory brick, the other is anchor, and the third is tortoise shell mesh. Anchors and tortoise shells are both metal products, only hanger refractory bricks are refractory products.
Hanger refractory bricks come in many shapes and ways of linking, and they vary in size. Under normal circumstances, it is made according to user customization. There are also some regular lengths of 330, 380, 440 and 500m, and the thickness is generally about 100mm to anchor the bricks, and its function is to act in the refractory castable lining.

Hanger refractory brick are available with and without holes, the use of holes and useful stove tops and walls without holes. The use is embedded in the castable, and it is also used for hanging with hanging parts, so it can also be called hanging brick.
The anchors are directly welded on the furnace shell, and the anchors are embedded in the lining for anchoring and connection when the refractory castable is poured.

The most commonly used are Y, V and L shapes, and the height is determined by the thickness of the refractory castable. If the thickness of the castable is 200mm thick, the height of the anchor can be 160-180mm. The anchor is easily oxidized at high temperature, and when it is buried in the castable lining, it should be determined by the thickness of the lining and the operating temperature.

Hanger refractory brick are refractory bricks that are re-formed and then sintered through the technical ratio of raw materials. They have high strength, good thermal shock stability and toughness. However, the mold of the hanger refractory brick is a difficult point in the production process. The abrasive tool is complex and difficult to make, and the mold cost is much higher than that of the general refractory brick.

If the hanger refractory brick has holes, the installation holes are generally at the neck. The finished anchoring bricks must not have cracks, and the dimensions should be accurate. Easy to use on the stove top. hanger refractory bricks generally use more high-alumina grades, because grade-three high-alumina hanger refractory bricks have toughness. Although the first-grade high-alumina bricks are of good quality, their hardness also increases, and they are prone to cracks when used in general castables.

Anchoring bricks play the role of skeleton connection in the pouring of castables. They are produced according to the requirements of users, but there must be no cracks. Cracks are easy to fall and affect the use of refractory castables.
