Скачать или смотреть Refractory Cement as Insulation Layer in Smoke Box

Refractory cement is widely used as an insulation layer in smoke boxes due to its high resistance to heat and its ability to maintain its structural integrity even at high temperatures. In this article, we will discuss the process of using high alumina aggregate and fine powder to create a refractory cement insulation layer in smoke boxes.

To create a refractory cement insulation layer, a mixture of high alumina aggregate (3-5mm) and fine powder is mixed with water. The refractory cement insulation layer should be at least 5cm thick and should be allowed to cure for 72 hours. During winter construction, the ambient temperature should not be lower than 5 degrees Celsius, otherwise insulation measures should be taken. After curing, the surface should be free of cracks and dense voids.

The high alumina aggregate and fine powder are mixed in a specific ratio to create the desired consistency and strength. The mixture is then applied to the smoke box using a trowel or other suitable tool. It is important to ensure that the mixture is evenly distributed and that it is applied in a thick enough layer to provide adequate insulation.

After the refractory cement insulation layer is applied, it must be cured for a minimum of 72 hours. This allows the cement to dry and harden, providing maximum insulation and structural integrity. During the curing process, the smoke box should be kept in a warm and dry environment, with a temperature not lower than 5 degrees Celsius.

Once the curing process is complete, the surface of the refractory cement insulation layer should be inspected for cracks and voids. Any cracks or voids should be filled in and smoothed over to ensure that the insulation layer is continuous and uniform.

Refractory cement is an excellent choice for creating an insulation layer in smoke boxes due to its high heat resistance and structural integrity. By using high alumina aggregate and fine powder in the right ratio and applying it properly, a strong and durable insulation layer can be created. It is important to follow the curing and inspection process to ensure that the insulation layer is uniform and free of defects.
