In industrial design, when the thickness or load of the furnace body structure is large, or the ambient temperature is high, the refractory brick structure serves as the anchor in the lining. Anchor bricks, hanging bricks, and anchors are mainly used for anchoring castables . The main material of anchor bricks is alumina. Our factory can customize anchor bricks with various indexes and sizes.

1.High Strength.
2.Good anti-stripping performance.
3.Good erosion resistance

It is widely used for the outer wall of industrial furnaces and flue.
