Manufacture of refractory products

NACE v2.0 Code: C23.20

About manufacture of refractory products

NACE code 23.20 covers the manufacture of refractory products, which are materials designed to withstand high temperatures and resist chemical and physical stresses. This industry plays a crucial role in supporting various sectors, including steel production, glass manufacturing, and the construction industry. Refractory products are essential for the efficient and safe operation of high-temperature industrial processes, contributing to the overall productivity and competitiveness of the economy.

Production process

The manufacture of refractory products typically involves a series of processing steps. Raw materials, such as clay, silica, and alumina, are extracted and refined. These materials are then crushed, milled, and mixed in precise proportions to achieve the desired chemical and physical properties. The mixture is then formed into the desired shapes, such as bricks, blocks, or monolithic linings, using techniques like pressing, casting, or extrusion. Finally, the products undergo high-temperature firing or sintering to enhance their strength, durability, and heat resistance.

Production inputs

The refractory products industry relies on a range of raw materials, including clay, silica, alumina, and various mineral additives. Specialized machinery, such as crushers, mills, and forming equipment, is also essential for the production process. Additionally, the industry requires significant energy inputs, primarily in the form of high-temperature furnaces and kilns used for the firing and sintering of the refractory products.

Production outputs

The primary outputs of the refractory products industry are a diverse range of heat-resistant materials, including bricks, blocks, linings, and other specialized products. These outputs are consumed by a variety of industries, such as 24.10 Steel production, 23.11 Glass manufacturing, and the 41.20 Construction industry. The refractory products manufactured under NACE code 23.20 are crucial for maintaining the efficiency and safety of high-temperature industrial processes across multiple sectors.
