Introduction of Plastic Refractory Castable
Main compositions of refractory plastic castable are powdery materials combined with binders such as plastic clay and plasticizers. Additionally, customers may add a small amount of water to form a hard mud paste that maintains high plasticity for a long period of time.
Granular and powdery materials are the main components of plastic refractory, which accounts for 70% to 85% of the total weight. They come from all kinds of refractory materials. Therefore, you can classify the plastic refractory castable according to the material. Since this kind of castable is mainly used in various heating furnaces that are not directly in contact with the melt, clay clinker and high-alumina clinker are generally used. Light granular materials can be used to make lightweight refractory castable. Sometimes for some special requirements, silica, sintered and fused corundum, chromium, silicon carbide, zircon and carbonaceous materials can also be used.
Plastic clay is an important part of plastic refractories. Although it only accounts for 10% to 25% of the total amount of plastics, it has a great influence on the bonding strength of plastics and their hardened bodies, the plasticity of plastics and the volume stability and fire resistance of hardened bodies. In a certain sense, it can be considered that the nature and quantity of clay determine the nature of plasticity.

Technical Guidance of Plastic Refractory Castable
- When using plastic castable as well as high alumina cement, the first thing to pay attention to is to clean up the corresponding construction parts before construction;
- If there is a need for steel bars or anchors, workers should prepare them on non-heated surfaces;
- When using plastic castable as furnace lining, workers can form it by manual mechanical ramming. If there is no specific regulation in the material instruction manual, workers has better to the ramm the furnace lining with a pneumatic pick or a tamping machine. What’s more, the wind pressure should not be less than 0.5MPa;
- When utilizing plastic refractory castable, please ram the furnace wall vertically and the furnace roof horizontally. In other words, you need to ensure that the ramming direction aligns parallel to the heating surface of the furnace lining.
- Once the tamping and formwork removal work is complete, you should promptly resurface the moldable refractory castable. To ensure a secure fit, workers can lightly tap the malleable castable around the refractory bricks with a rubber hammer. In addition, please judge whether the surface of the anchor brick needs to be trimmed according to the situation.
