Mullite Castable Production - Xinhongji Refractory

Mullite castable refractories are high-performance materials widely used in high-temperature industrial applications due to their excellent thermal stability, mechanical strength, and corrosion resistance. Composed primarily of synthetic mullite (3Al₂O₃·2SiO₂), these castables exhibit low thermal expansion, superior thermal shock resistance, and prolonged service life in extreme environments. They are commonly applied in furnaces, kilns, incinerators, and boilers, particularly in the steel, cement, and petrochemical industries.

Mullite castables offer easy installation through casting or gunning techniques, ensuring dense, crack-free linings after curing and firing. Their high alumina content enhances refractoriness (up to 1800°C), while additives like silica fume or microsilica improve workability and sintering properties. With tailored compositions, they balance cost-efficiency and durability, making them ideal for demanding thermal processes.

High Alumina Insulating Bricks

图片
 🔥 High alumina insulating refractory bricks are a special type of brick that can handle high temperatures and act as insulation. Insulating bricks are used to line fireplaces, fireboxes, furnaces, and kilns. It is designed to withstand temperatures of up to 1760°C while actually conducting very little of that heat in order to provide a greater level of energy efficiency. 🔥 Insulating refractory bricks are refractory bricks or blocks, of a ceramic material that is commonly used in a variety of different applications including fireboxes, all types of furnaces, melters, and industrial kilns. 👉 Xinhongji Refractory specializes in the production of high alumina insulating bricks , If you have any needs related to refractory products, please feel free to contact us, we can satisfy you 100%! 📣 Contact now: sales@hongjirefractory.com ☎️ Whatsapp/Wechat: +86-17026790777 🔗 https://www.hongjirefractory.com/high-alumina-insulating-bricks.html 👉 If you need high alumina insulating bricks...

Refractory brick production line - Xinhongji Refractory

图片
A refractory brick production line is a specialized manufacturing system designed to produce high-temperature-resistant bricks used in industries such as steel, cement, glass, and ceramics. The process begins with the selection and mixing of raw materials like alumina, silica, and fireclay. These materials are crushed, ground, and blended to ensure uniformity. The mixture is then shaped into bricks using hydraulic presses or extrusion machines. After forming, the bricks undergo drying to remove moisture before being fired in high-temperature kilns (up to 1600°C) to achieve superior strength and thermal stability. Advanced automation ensures precision in sizing and quality control. The final products exhibit excellent resistance to heat, corrosion, and mechanical stress, making them essential for lining furnaces, kilns, and reactors. Modern production lines emphasize energy efficiency and environmental sustainability. 🔥 Hot sale! Refractory Bricks 📣 Contact now: sales@hongjirefractory...
