What is the construction process for refractory castables?
The core construction process for refractory castables strictly follows the standardized sequence: material preparation and mixing → substrate treatment → formwork erection → casting and vibration → curing → demolding → baking. It is essential to rigorously control the process parameters at each stage to ensure the integrity, density, and refractory performance of the finished lining. This process is suitable for constructing and repairing linings in kilns and thermal equipment used in industries such as steel, cement, and glass. The following are the key operational points for each stage: 1. Material Preparation and Mixing: Weigh the castable powder, aggregates, and mixing water according to the product’s specified ratio (absolutely avoid adding excess water). Use a forced-action mixer for thorough blending—first dry-mix for 2–3 minutes until the color is uniform, then gradually add water and wet-mix for another 3–5 minutes. After mixing, the material should have a fluid consistency with no lumps. Use the mixture immediately after preparation (to prevent initial setting).

What is the function of refractory castables?
Refractory castables are loose, granular refractory materials composed of granular and powdered refractory raw materials mixed with binders and additives. They can be prepared on-site by mixing and pouring, then compacted and vibrated into shape. These materials combine excellent refractoriness, monolithic integrity, and construction flexibility, making them the core lining material for industrial kilns and thermal equipment. They are widely used in high-temperature industrial sectors such as iron and steel, cement, nonferrous metallurgy, glass, and power generation. Their primary functions revolve around providing refractory protection, structural support, and operational adaptability for high-temperature equipment, while also addressing the drawbacks of traditional shaped refractory products—such as cumbersome installation procedures and vulnerable joints.
