Manufacture of refractory products

NACE v2.1 Code: C23.2

About manufacture of refractory products

NACE code 23.2 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 24.1 Manufacture of basic iron and steel and 23.5 Manufacture of cement, lime and plaster, by providing the specialized materials needed for their production processes. The refractory products industry is an integral part of the broader manufacturing landscape, contributing to the overall efficiency and sustainability of industrial operations.

Production process

The manufacture of refractory products typically involves a series of complex processes. This includes the mining and processing of raw materials, such as clay, silica, and alumina, to create specialized formulations. These raw materials are then shaped, dried, and fired at high temperatures to produce a range of refractory products, including bricks, blocks, and monolithic materials. Advanced techniques, such as extrusion and pressing, may be employed to ensure the desired properties and performance characteristics of the final products.

Production inputs

The refractory products industry relies on a variety of raw materials, including clay, silica, alumina, and other mineral resources. Additionally, the industry requires specialized machinery and equipment, such as kilns, crushers, and mixing systems, to facilitate the production process. Energy sources, such as natural gas or electricity, are also essential inputs for the high-temperature firing and drying stages of refractory manufacturing.

Production outputs

The primary outputs of the refractory products industry are a diverse range of materials designed to withstand high temperatures and harsh environments. These include bricks, blocks, and monolithic products used in the construction of furnaces, kilns, and other industrial equipment. The refractory products manufactured under NACE code 23.2 are often consumed by industries such as 24.1 Manufacture of basic iron and steel, 23.5 Manufacture of cement, lime and plaster, and 23.9 Manufacture of other non-metallic mineral products.
