Refractory castable is a relatively new type of refractory material presently, it is easier to construct than refractory bricks, and its performance is better than refractory bricks. Because it is a whole or cast or painted manually, the wear resistance and fire resistance are better. From the Rongsheng Refractory Manufacturer, the refractory castables are used in many places, such as power plant boilers, large cement kilns, large rotary kiln, CFB boilers. Refractory castables can exist as an integral lining inside the boiler.

Application of the Refractory Castables

In recent years, refractory castables have been used not only to make new unshaped refractory linings, but also to be widely used as refractory linings in repair and maintenance services. There are various construction methods for refractory castables, including pouring, spraying, ramming and pressing with and without vibration (self-flowing material). Some construction methods have become and will continue to be the main construction methods for refractory castables. According to the traditional method, refractory castables are used as the hearth (alkaline refractory) of traditional electric arc furnaces, shotcrete, blast furnace iron ditch and some repair and maintenance materials. In some cases, complex shaped articles have been replaced by unshaped refractories, resulting in composite linings. An example is the waste incinerator.

The refractory castable is actually a jointless lining, which has a certain shape when used. A typical example of the extended use of castables is the development of linings for unshaped refractory castables used on ladles. In principle, the ladle lining can be divided into unshaped refractory castables and shaped refractory brick products. The material is high alumina bricks (neutral) or alkaline. The inline refractory castable linings made with refractory castables are mainly limited to high alumina materials, and shaped products can be neutral or alkaline materials.

The advantages of rapid application of unshaped refractory castables (using new binders) and reduced drying and heating times will play an important role. Because the use of unshaped refractory castables will bring undeniable economic benefits. Therefore, continuous improvement in quality and simple construction will ultimately make it more economical to use. Rongsheng refractory manufacturers have a special refractory castable factory, which aims to provide customers with high-quality refractory lining.
