What Are Castables Commonly Used in Heating Furnaces

For the refractory good material is widely used is castable and as the application of the occasion of different appliances will also have a different kind of material to choose, and usually heating furnace commonly used refractory castable what.

Refractory castable refers to the mixture composed of refractory aggregate, binder and admixture, which is mixed with water and can be constructed by pouring method. Different from other amorphous refractory, refractory castable has certain setting and hardening time after construction.

If the use of low cement castable is suitable for heating furnace of high temperature, temperate zone and has a moderate solidification rate, good thermal shock resistance, high softening temperature under load, slag resistance, high refractoriness. Mullite castable material can be used in the heating furnace wall, roof and pressing beam and other key parts or used to prefabricate burner bricks.

And the self-leveling castable can be applied to the heating furnace structure is more complex or artificial can not vibrate the position characteristics are the same as the low cement castable.For phosphate castable, it is applied to some parts that are subjected to severe friction and hot air scour to ensure good internal corrosion resistance and a small amount of fiber can be added to increase its toughness. 

Refractory castable is a granular powder material made of refractory material, consisting of a certain amount of binder and water. It has high fluidity and is suitable for casting construction and can be used to harden amorphous refractories without heating. An amorphous refractory castable formed by casting in comparison with other amorphous refractory castables.

Refractory castable uses high binder and moisture content, good fluidity. Therefore, amorphous refractory castable has a wider range of applications, according to the application conditions can be selected raw materials and adhesives. It can be cast directly into a lining, or it can be poured or shaken into prefabricated blocks.

When the castable is mixed with the forced mixer, it is necessary to pay attention to these aspects during the construction. Mixing time and liquid participation should be completed according to the construction instructions. When changing different materials, mixers, hoppers and weighing containers should be cleaned.

Above is the type of pouring material commonly used in heating furnace introduction hope that we can consider in advance and consult manufacturers in time in case of the use of the choose and choose problem.
