High Aluminum Refractory Castable

High aluminum refractory castable is a kind of refractory material that is used for a variety of industrial processes. These materials are typically used in boilers, furnaces, heat treatment furnaces, and power stations. The high aluminum content helps to increase strength and decrease thermal conductivity of the material. It also has excellent thermal stability.

There are several types of high aluminum refractory cement. High alumina cement is a common choice for refractory cement, as it provides a high hydraulically active setting effect. This cement also has a very short setting time, usually less than a day. The alumina content of high-alumina cement is one of the main factors influencing the refractory cement's early strength and durability. Nevertheless, there is a tradeoff between the alumina content and the cement's later strength.

High aluminum refractory castables are manufactured by a reputable company. This company can deliver the finished product to a specific location, and the user can then build the structure according to the manufacturer's specifications. The process of producing these castables involves the addition of liquid, vibration forming, curing, and baking.

High aluminum refractory castables can be used in various industrial processes. They are available in different types, such as SK30, SK34, and SK36. They can also be used as high-temperature kiln lined refractory bricks.

High aluminum refractory castables have a high mechanical strength and excellent thermal shock resistance. These refractory materials are widely used in the chemical and steel industries. Their high alumina content makes them ideal for lining furnaces. The density of high aluminum refractory materials ranges from 2.5 to 2.8.

The ratio of lime/silica to the refractory powder is an important factor in determining refractory lining performance. In general, the ratio of aggregate to powder is 70:30, while the percentage of water is 10%. Increases in cement dosage improves pressure resistance at room temperature and increases linear shrinkage after burning.

Corundum low-cement refractory castables are also used in industrial processes. These materials have excellent thermal shock resistance, extreme abrasion resistance, and excellent heat resistance. They are also commonly used for general purpose castables. Moreover, they are highly resistant to corrosion caused by chemical agents.

In addition to the thermal shock stability of high aluminum bricks, the phase composition of these products is also important. Improved particle composition in the mud can result in better thermal shock resistance and higher product strength. Zircon micro-powder can be added to the raw materials to improve the particle structure of the products.
