With the development of society and the progress of the times, our lives have become more colorful, and every bit of our lives are undergoing subtle changes. These changes from our production and life can be found in the materials. We live in a world of various life and production. As our lives progress, our requirements for some living materials around our lives are also constantly increasing. As one of the common building materials in our lives, magnesia bricks have always attracted the attention of the public. Next, let us have a corresponding understanding of it.
Introduction to magnesia bricks
An alkaline refractory material with a magnesium oxide content of more than 90% and periclase as the main crystal phase.
Generally, it can be divided into two categories: sintered magnesia bricks (also known as fired magnesia bricks) and chemically bonded magnesia bricks (also known as unfired magnesia bricks). Magnesia bricks with high purity and firing temperature are called direct bonded magnesia bricks due to direct contact between periclase grains; bricks made of fused magnesia as raw materials are called fused rebonded magnesia bricks.
Magnesia bricks have high refractoriness, good resistance to alkaline slag, and a high starting temperature for softening under load, but poor thermal shock resistance. Sintered magnesia bricks use brick-making magnesia bricks as raw materials. After crushing, batching, mixing, and shaping, they are fired at a high temperature of 1550 to 1600°C. The firing temperature of high-purity products is above 1750°C. Unpoured magnesia bricks are made by adding appropriate chemical binders to magnesia, mixing, shaping and drying.
Mainly used for steelmaking alkaline open hearth furnace, electric furnace bottom and furnace wall, permanent lining of oxygen converter, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and cement rotary kiln lining, heating furnace The furnace bottom and furnace wall, glass kiln regenerator checker bricks, etc.!
Examples of magnesia brick manufacturers:

The company's main products include intermediate frequency furnace lining magnesia knotted materials, intermediate frequency furnace lining aluminum knotted materials, magnesia bricks, magnesia carbon bricks and magnesia chrome bricks. Magnesia raw materials include fused magnesia, large crystalline fused magnesite, fused magnesite chromium sand, recycled magnesia carbon granules, recycled magnesium aluminum carbon granules, recycled magnesia chromium granules, and recycled magnesia aluminum spinel granules. , recycled magnesia granules, etc.
The society we live in is constantly developing, and it is precisely because of the continuous development of our society that our lives have become more colorful. Our lives have become better because of the existence of these different and various materials. Most of us are not very unfamiliar with magnesia bricks, so there is no need to introduce too much to you here. Here we just briefly introduce to you the production of magnesia bricks, which is more influential. manufacturer, I hope it will be helpful to everyone.
