What are the effects of raw materials on the stability of insulating refractory bricks

The performance of insulating refractory bricks is directly affected by the type of raw materials, especially in terms of chemical composition and physical properties. Dongtai Hongda Heat Resistant Material Co., Ltd. mainly uses refractory clay as the core raw material in the production process. This is because refractory clay not only has excellent refractory properties, but also shows good plasticity, making it an ideal choice for manufacturing insulating refractory bricks. In order to meet the specific needs of customers and the performance requirements of products, the company will also add light materials such as floating beads, refractory clay clinker, fly ash, etc. according to actual conditions. The addition of these lightweight materials not only effectively reduces the volume density of the product, but also significantly improves its thermal insulation performance, optimizes the microstructure of the insulating refractory bricks, and enhances thermal shock resistance and wear resistance.

In the production of insulating refractory bricks, the composition of raw materials is crucial to their stability and reliability. Dongtai Hongda Refractory Material Co., Ltd. strictly controls the chemical composition, especially the content of alumina (Al2O3), in the selection of raw materials. Alumina is one of the main components of refractory materials, and its content directly affects the refractoriness and corrosion resistance of insulating refractory bricks. In order to ensure that the Al2O3 content of each batch of raw materials is within the specified range, the company uses precise chemical composition analysis to ensure the stability and consistency of the product, thereby improving the reliability of the final product.

The processing technology of raw materials also has a profound impact on the performance of insulating refractory bricks. In the production process of Dongtai Hongda Refractory Materials Co., Ltd., the raw materials go through several key links such as batching, mixing, molding, drying and firing. Among them, the molding and firing stages are crucial to the final performance of the product. During the molding process, the raw materials need to be evenly pressed to ensure that the density and strength of the product meet the standards; and during the firing stage, the raw materials need to undergo high-temperature sintering to form a dense microstructure. Dongtai Hongda Refractory Materials Co., Ltd. uses advanced molding and firing technologies to ensure that the raw materials are fully processed during the processing process, which not only improves the stability of insulating refractory bricks, but also extends their service life.
