What is the Difference between Refractory Mortar, Refractory Ccement, and Refractory Castable?

Refractory mortar, refractory cement, and refractory castables are all unshaped refractory materials, and they are often mentioned in the refractory industry, and they are relatively common in the use of kiln refractory lining materials. Refractory mortar is used to build refractory bricks, also called refractory mud or jointing material, used as a jointing material for refractory bricks product masonry. Refractory cement is a material for making refractory concrete(castable). Refractory castables are made of refractory aggregates, powders, and binders. They are called refractory castables due to their casting construction method.

RS High-Quality Refractory Mortar

Refractory Mortar

Refractory mortar can be divided into clay, high alumina, silica, and magnesia refractory mortar according to the material. It is composed of refractory powder, binder, and admixture. Refractory clinker powder, adding the appropriate amount of plastic clay as a binder and plasticizer and made of general refractory clay. Its normal temperature strength is low, and the ceramic bond has high strength at high temperatures. The particle size of refractory mortar varies according to the application requirements, and its limit particle size is generally less than 1mm, and some are less than 0.5mm or finer.

The selection of refractory mortar materials should be considered together with the materials of refractory products of masonry. In addition to being used as a jointing material, refractory mud can also be used as a maintenance coating for the lining by alteration method or spray method.

Refractory Cement

Refractory Cement

What is refractory cement? Refractory cement is also called aluminate cement. Aluminate cement is a hydraulic cementitious material made of bauxite and limestone as raw materials, calcined to produce clinker with calcium aluminate as the main component and about 50% alumina content, and then ground. Aluminate cement is often yellow or brown, but also gray. Used as lining material for industrial kilns.

Rongsheng Refractory Castables

Refractory Castables

Refractory castable is a kind of unshaped refractory material that is widely produced and used. It is mainly used to construct various heating furnace linings and other integral structures, and some high-quality varieties can also be used in smelting furnaces. For example, aluminate cement refractory castables can be widely used in various heating furnaces and other thermal equipment without slag, acid, and alkali corrosion. Refractory castable products are also used in parts that are corroded by molten iron, molten steel, and molten slag and have higher working temperatures, such as tapping troughs, ladles, blast furnace shafts, and tapping channels. In some parts of metallurgical furnaces and other vessels that are in direct contact with slag and molten metal, the use of high-quality phosphate refractory castables for repairs also has an excellent effect.

From the above, we can see that although the three products are all monolithic refractories, their uses are quite different. And each product is divided into different models and types, so you can consult professional technicians when purchasing. Choosing a suitable refractory lining material product can not only guarantee the construction period of the refractory lining material but also strengthen it to avoid necessary losses and save investment and production costs.
