Ceramic Fiber Blanket Refractory

Ceramic fiber blanket refractory is a material used for high temperature thermal insulation. It is made of high-purity alumina, silica and other materials, and has the characteristics of light weight, low thermal conductivity and good thermal shock stability. It has been widely used in steel, electric power, building materials and other industries. The following is a detailed introduction to the production process of refractory ceramic fiber blankets.

1. Raw material preparation

The key to producing ceramic fiber blanket refractory is the preparation of raw materials. The selection and quality of raw materials have a great impact on the quality of the final ceramic fiber blankets. Commonly used raw materials include high-purity alumina, silica, calcite, etc. These raw materials need to be stored uniformly in raw material warehouses. During the production process, the types, proportions and quantities of various raw materials need to be determined according to the production plan, and sent to the batching room for batching.

2. Mixing ingredients

The proportioning and mixing of raw materials is a key step in the production of ceramic fiber blankets. Scientific and reasonable proportioning and mixing need to be carried out according to product quality requirements and requirements in the production process. Usually, fine powders such as high-purity alumina and silica are mixed according to a certain proportion, and then an appropriate amount of clean water and surfactant are added for stirring to fully moisten the powder and form a uniform mud. That is the slurry in the production of ceramic fiber blankets.

3. Fiber blanket production

After the uniform slurry is made, it is transported to the ceramic fiber blanket refractory production line for the next step. On the production line, the slurry is evenly sprayed on the network roller with a certain strength and compacted by a certain pressure to form a blanket. At the same time, a high-speed rotating centrifuge is used to spin the blanket to turn it into a uniform high-temperature fiber blanket. After making the blanket, it is put into a high-temperature kiln for drying, calcining and other processes to form the finished product.

4. Finished product packaging and quality inspection

The calcined ceramic fiber blanket needs to be packaged and quality inspected. In the packaging of finished products, the ceramic fiber blankets need to be packaged, labeled and packaged to ensure that they meet production standards and stored in designated storage warehouses. During quality inspection, tests such as density, thermal conductivity, thermal expansion coefficient and heat resistance need to be carried out. Only products that pass the inspection can be delivered to downstream customers.

The above is the production process of ceramic fiber blanket refractory. The entire production process is strictly operated in accordance with the production process and standards to ensure the best product quality. As ceramic fiber blankets are increasingly used in high-temperature industries, their production processes and technologies are constantly advancing, providing a solid guarantee for the development of high-temperature insulation fields.
