Refractory bricks, also known as fire bricks, are a subset of construction materials with exceptional resistance to heat, chemical attack, and mechanical wear. They are integral components in a variety of high-temperature industrial processes, from ironmaking and steelmaking to glass production and power generation.
the bricks are heated only on one face, most of the load is carried by the relatively cooler rigid portion of the bricks. Hence the RUL, test gives only an index of the refractory quality, rather than a figure which can be used in a refractory design. Under service conditions, where the refractory used is heating from all sides such as

Two other types of refractory processes also warrant discussion. The first is production of fused products. This process involves using an electric arc furnace to melt the refractory raw materials, then pouring the melted materials into sand-forming molds. Another type of refractory process is ceramic fiber production.
