Unfired refractory products; other refractory ceramic goods

CPC v2.1 Code: 3734

About unfired refractory products; other refractory ceramic goods

cpc code 3734 covers the production of unfired refractory products and other refractory ceramic goods. These materials are essential for industries that require high-temperature resistance, such as steel manufacturing, glass production, and cement kilns. As a key component in many industrial processes, the 3734 industry plays a vital role in supporting the broader economy and enabling the manufacture of a wide range of products.

Production process

The production of unfired refractory products and other refractory ceramic goods typically involves the mixing and molding of raw materials, such as clay, silica, and alumina. These materials are then dried and fired at high temperatures to create the desired refractory properties. Specialized techniques, such as extrusion, pressing, and casting, may be used depending on the specific product being manufactured.

Production inputs

The main inputs required for the 3734 industry include raw materials like clay, silica, and alumina, as well as energy sources for the high-temperature firing process. Specialized machinery, such as kilns, mixers, and molding equipment, are also essential for the production of these refractory products.

Production outputs

The primary outputs of the 3734 industry are unfired refractory bricks, tiles, and other shapes, as well as various refractory ceramic goods. These products are then consumed by industries such as 3312 Iron and Steel Mills and Ferroalloy Manufacturing, 3241 Cement and Concrete Product Manufacturing, and 3272 Glass and Glass Product Manufacturing, where they are used to construct and maintain high-temperature equipment and infrastructure.
