Standard Dimensions of Refractory Bricks

The standard dimensions of refractory bricks are 230×114×65 mm. According to relevant regulations in China, common refractory bricks are categorized into five types:

1. Straight bricks
2. Side arch bricks
3. Vertical arch bricks
4. Vertical thick bricks
5. Arch foot bricks

The frequently mentioned standard refractory brick is a specific size within the straight bricks category. These bricks are made from refractory clay or other refractory materials and are typically light yellow with a brown hue. They can withstand high temperatures ranging from 1580°C to 1770°C and endure various chemical and physical changes and mechanical actions under such high temperatures. Different types of refractory bricks can be used together.

What Are Refractory Bricks Made Of?

Refractory bricks are made from refractory clay and other refractory materials. They are categorized into two types: unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also known as castables, are composed of various aggregates and binders and need to be mixed with liquids. Shaped refractory materials refer to refractory bricks, which have standard shapes and must be cut according to construction requirements.

Tips for Choosing Refractory Bricks

1. Determine Requirements: First, consider what type of bricks you need and the specific kind of refractory clay bricks you want.
2. Choose the Right Manufacturer: When selecting refractory bricks, it is essential to choose a reliable manufacturer. Compare products from different manufacturers, not only in terms of price but also considering their reputation and after-sales service.

Types and Uses of Refractory Bricks

Refractory bricks can be classified based on their production process into fired bricks, unfired bricks, and fused bricks, among others. Based on shape and size, they can be divided into standard bricks, common bricks, and special-shaped bricks. These materials are widely used, for instance, in constructing blast furnaces for ironmaking or converters. The type of furnace determines the kind of bricks used.

Summary of Refractory Brick Standards

The standard dimensions of refractory bricks are 230×114×65 mm, representing the length, width, and height respectively. While this is the standard size, there are also non-standard refractory bricks available.
