Nonmolded refractories are used to make refractory concrete and often include additives to ensure hardening at ordinary temperatures or after drying. Refractory concrete can be used to manufacture large blocks that weigh from 150–300 kg to 10–20 tons and even more; these are delivered in finished form to the construction site.
It is well known that nonmetallic inclusions could form inside the steel or is descended from external sources like refractory bricks, slag or alloying materials. Theirs composition and size are directly depended of steel, slag or ceramic materials compositions. When the molten steel is treated in a ladle, the reaction between steel and
Standard shapes are usually bricks that have a standard dimension of 9 × 4 1 ⁄ 2 × 2 1 ⁄ 2 inches (230 × 114 × 64 mm) and this dimension is called a "one brick equivalent". "Brick equivalents" are used in estimating how many refractory bricks it takes to make an installation into an industrial furnace.

Refractory Bricks; Refractory brick for sale in Rongsheng is a kind of shaped refractory material with certain shape and size, which is manufactured through firing fireclay or other refractory raw materials for building kiln, furnace and various heating equipment to bear all kinds of physical chemistry change and mechanical action under the ...
Carbon brick is a kind of carbon refractory materials, which contain carbon more than 80%.. Carbon is an ideal material for lining vessels that is under severe chemical or physical operating conditions, because carbon has stable chemical stability,which is resistant to chemical attack, such as the erosion of acid, alkali, salinity, and organic solvent.
Its high density does not usually provide adequate thermal insulation that instead is provided by a separate, porous, outer layer of refractory in brick, powder, or fiber form (the LTM refractory). This second layer is also the safety lining that provides backup in case of failure of the contact layer.
Refractory. One of a number of ceramic materials for use in hightemperature structures or equipment. The term high temperatures is somewhat indefinite but usually means above about 1830°F (1000°C), or temperatures at which, because of melting or oxidation, the common metals cannot be used.
