Magnesia-chrome refractory castables are widely used in various high-temperature industrial furnaces due to their excellent thermal shock resistance and corrosion resistance. As a kind of refractory material, magnesia-chrome refractory castables can be divided into different grades according to their performance and application requirements.
The grades of magnesia-chrome refractory castables are mainly divided into high-aluminum and low-aluminum magnesia-chrome refractory castables. The technical parameters of magnesia-chrome refractory castables mainly include bulk density, compressive strength, refractoriness, thermal shock resistance, and chemical composition. For instance, the bulk density of magnesia-chrome refractory castables is usually between 2.9-3.1g/cm3, and the compressive strength is usually between 70-100MPa.
The production process of magnesia-chrome refractory castables usually includes the preparation of raw materials, mixing, adding additives, spraying, and drying. The specific production process may differ according to the product grade and application requirements.
To maintain the quality and performance of magnesia-chrome refractory castables, it is essential to pay attention to the storage and transportation of the products. The products should be stored in a dry and ventilated place to avoid moisture absorption and oxidation.
In conclusion, magnesia-chrome refractory castables are essential materials in the high-temperature industry. By dividing them into different grades, determining their technical parameters, and optimizing the production process, we can produce magnesia-chrome refractory castables that meet specific application requirements. With the constant development of high-temperature industry, magnesia-chrome refractory castables will play a more important role in the future.
