Manufacture of refractory products

NACE code 23.20 covers the manufacture of refractory products, which are materials designed to withstand high temperatures and are essential for a wide range of industrial processes. This industry plays a crucial role in supporting various sectors, including steel production, glass manufacturing, and the construction of industrial furnaces and kilns. The refractory products industry is a key component of the broader manufacturing landscape, contributing to the efficient and reliable operation of many critical industrial facilities.

The manufacture of refractory products typically involves the processing of raw materials, such as clay, silica, and various mineral additives, through a series of steps. These include crushing, grinding, mixing, and shaping the materials into the desired forms, such as bricks, blocks, or monolithic linings. The shaped products are then subjected to high-temperature firing or sintering processes to enhance their durability and heat resistance.

The main inputs required for the refractory products industry include a variety of raw materials, such as 08.12 Clay and kaolin, 08.11 Silica sand, and other mineral resources. Additionally, the industry relies on specialized machinery and equipment for the various production stages, as well as energy sources, such as natural gas or electricity, to power the high-temperature processes.

The primary outputs of the refractory products industry are a diverse range of heat-resistant materials, including bricks, blocks, and monolithic linings, which are used in various industrial applications. These refractory products are often consumed by industries such as 24.10 Manufacture of basic iron and steel, 23.11 Manufacture of flat glass, and 23.31 Manufacture of ceramic tiles and flags, among others, where they play a crucial role in maintaining the integrity and efficiency of high-temperature processes.
