The main raw materials of basic refractory bricks are magnesia, dolomite and limestone. Therefore, they are very resistant to basic slag and iron slag. Kerui is committed to providing high-performance basic refractory bricks of various materials and sizes. Please leave your contact information and required products here! We will provide you with cost-effective refractory bricks.
What are Basic Refractory Bricks Consist of?
Basic refractory bricks are mainly composed of magnesium oxide and calcium oxide, and magnesia bricks are commonly used. Magnesia bricks containing more than 80% to 85% magnesium oxide have good resistance to basic slag and iron slag. Moreover, its refractoriness is higher than that of clay bricks and. According to different production processes and use environments, basic refractory bricks can be divided into different types such as magnesia brick, magnesia chrome brick, and magnesia spinel brick. We can use basic fire bricks in open-hearth furnaces, oxygen-blown converters, electric furnaces, and non-ferrous metal smelting equipment.
Characteristics of Basic Refractory Bricks Under High Temp
In the daily use of basic refractory bricks, it is necessary to regularly inspect and maintain the basic refractory bricks. Because we need to repair and replace the damaged parts in time. However, the magnesium bricks produced by Kerui can withstand various physical and chemical tests. Choosing Kerui’s high temp refractory bricks can greatly reduce the maintenance frequency of industrial equipment and extend the service life of the equipment.

Basic Refractory Bricks for Industrial Equipment
Metallurgical Industry
It is used for the lining of smelting furnaces, converters and blast furnaces. Keri’s magnesia fire bricks can effectively protect the furnace body and ensure the smooth progress of the smelting process.
Lime and Cement Industry
We often see it in lime kilns and cement kilns. It can protect the kiln from the erosion of slag for a long time and stably, greatly extending the service life of the kiln and improving production efficiency.
Chemical Industry
In high-temperature furnaces and reaction towers, alkaline magnesia brick can resist chemical reactions containing high concentrations of alkaline substances.
Glass manufacturing Industry
The internal environment of the glass melting furnace is extremely harsh. Therefore, the quality of magnesia brick is crucial to the stability of the melting furnace. Keri’s alkaline fire brick for furnace can maintain long-term stability in high temperature and alkaline environments, reducing equipment downtime.
