Anchor Brick

Anchor Brick is a specialized refractory brick designed for the top walls of industrial furnaces. Embedded in refractory castable walls and activated after baking at a specific temperature, it enhances the overall performance of the castable. Available in two forming techniques—semi-dry pressing and pouring vibration molding—our Anchor Bricks boast high refractoriness, strength, and excellent resistance to thermal shock, making them ideal for diverse high-temperature industrial applications.

Description

1. Anchor brick Description

Anchor Brick serves as a crucial component for the top walls of industrial furnaces. By embedding it in refractory castable walls and baking it at a certain temperature, it significantly improves the overall performance of the castable. In terms of production technology, it can be categorized into two types:

Semi-dry Pressing Molding：Offers good dimensional accuracy and structural density.

Pouring Vibration Molding：Provides enhanced homogeneity and adaptability to complex shapes.
