Refractory Brick Manufacturing Process | Bluewind Vermiculite Insulating Firebrick

Bitwater (Shenzhen) Technology Co., Ltd. follows a meticulous and advanced refractory brick manufacturing process. It begins with the careful selection of high - quality vermiculite as the primary raw material. The vermiculite is then processed through a series of steps, starting with expansion to enhance its insulating properties. After expansion, the vermiculite is mixed with precisely measured additives and binders, which are selected based on the desired properties of the final product, such as density, strength, and thermal conductivity. The mixture is then shaped into the desired brick form using specialized molding equipment, ensuring consistent dimensions and high - quality surface finish. Subsequently, the formed bricks undergo a controlled firing process at high temperatures in industrial kilns. This firing process not only solidifies the structure of the bricks but also improves their thermal insulation, strength, and resistance to chemical corrosion. Throughout the manufacturing process, strict quality control measures are implemented at every stage, from raw material inspection to final product testing, to ensure that each refractory brick meets the company's high - performance standards and customer requirements.
