Refractory brick is refractory material with certain shape and size. Their shape has standard rules, but also can be built and cut as necessary temporarily according to the need. Refractory bricks for sale are made form refractory clay or other refractory raw materials with the color light yellow or brown.
All kinds of cheap fire bricks for sale can be purchased in RS Kiln Refractory Company.As a kind of shaped refractory materials, different from unshaped refractories, fire bricks for sale in Rongsheng have a standard shape and can be temporarily processed as needed.
A fire brick, firebrick, or refractory brick is a block of refractory ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency.
Refractory. One of a number of ceramic materials for use in high-temperature 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.

Alibaba offers 1,797 used fire brick products. About 84% of these are refractory, 6% are brick making machinery, and 3% are bricks. A wide variety of used fire brick options are available to you, such as mullite, alumina block, and alumina cement.
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 back-up in case of failure of the contact layer.

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.
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.
A blast furnace is a special type of furnace for smelting iron from ore.Blast furnaces are very large. They can be up to 60 metres (200 ft) tall and 15 metres (49 ft) in diameter.The blast furnace is the biggest chemical reactor.Blast furnaces are also called high ovens.. A blast furnace is usually built with a steel case and bricks made of magnesium oxide or other refractory material inside ...
Carbon Refractory is a kind of quality furnace refractory material that is manufactured with raw materials of heat treating anthracite or coke and graphite and binding agent of coal tar pitch, which contains over 80% fixed carbon content and mainly is used as furnace lining for bottom, hearth, lower stack and launder of blast furnace with properties of high temperature resistance, excellent ...
Firebrick, refractory material consisting of nonmetallic minerals formed in a variety of shapes for use at high temperatures, particularly in structures for metallurgical operations and glass manufacturing. Principal raw materials for firebrick include fireclays, mainly hydrated aluminum s
High Alumina Bricks are a kind of commonly used refractory materials for sale in RS Company, which is mainly made of Al2O3. High Alumina Brick has properties of high refractoriness, high strength, acid and washing erosion resistance, good thermal stability and so on.
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 ...
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.
Refractory - Refractory - Non-clay-based refractories: Nonclay refractories such as those described below are produced almost exclusively as bricks and pressed shapes, though some magnesite-chrome and alumina materials are fuse-cast into molds. The usual starting materials for these products are carbonates or oxides of metals such as magnesium, aluminum, and zirconium.
