Refractory materials are generally divided into two types, namely unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also known as castables, are a mixture of various aggregates or aggregates and one or more binders. When used, they are mixed evenly with one or more liquids and have strong flowability. Shaped refractory materials generally refer to fire-resistant bricks, which have standard and regular shapes and can also be temporarily processed during construction and cutting as needed.

High alumina refractory bricks

Refractory bricks are abbreviated as firebricks. Refractory materials made by firing refractory clay or other refractory materials. Light yellow or brownish in color. Mainly used for building smelting furnaces, capable of withstanding high temperatures ranging from 1580 ℃ to 1770 ℃. Also known as firebricks. Refractory materials with a certain shape and size. According to the preparation process, it can be divided into fired bricks, unburned bricks, electric fused bricks (fused cast bricks), and fire-resistant and insulated bricks; According to shape and size, it can be divided into standard bricks, ordinary bricks, special bricks, etc. It can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures. For example, refractory clay bricks, high alumina bricks, silica bricks, magnesium bricks, etc

According to the different components of refractory bricks, they can be divided into five categories, namely: silicon aluminum series refractory bricks, alkaline series refractory bricks, carbon containing refractory bricks, zirconium containing refractory bricks, and insulation refractory bricks. Any furnace is not built with just one type of refractory brick, it requires a combination of different refractory bricks to be used.
