UNIFRAX Silplate Mass

UNIFRAX Silplate Mass

Silplate Mass is made from polycrystalline ceramic fibers and high-purity refractory oxides. It requires no dilution and can be used as-is. It is suitable for use in environments with temperatures of up to 1500°C. After drying, it forms a highly flame-resistant surface that is not easily worn down, even at high airflow velocities. It has a low shrinkage rate, reducing the likelihood of cracks in concrete and ceramic fiber insulation materials.

Silplate Mass can be used to protect:

1. Ceramic fiber wool bricks
2. Insulation and refractory castables
3. Insulating and refractory bricks
4. It is also used for repairing cracks and filling areas with deteriorating concrete.

Characteristics

1. Sealing gaps and localized repairs in refractory bricks.
2. Increasing the gas flow velocity of refractory materials up to 60 m/s.
3. Enhancing the wear resistance of ceramic fibers.
4. Reducing the shrinkage of ceramic fibers.
5. Minimizing heat loss due to shrinkage gaps in refractory materials.
6. Extending the lifespan of castable refractories.

Case Study: Improvement of Cracking Furnace in 2021

In order to improve the high-temperature impact on the cracking furnace walls, the client commissioned the purchase of high-temperature wear-resistant coating, Silplate Mass. The application of Silplate Mass was carried out during the annual maintenance period. Initially, the planned construction location was the entire row of furnace walls on the east side of Cracking Furnace 2F, from burner number 1 to 12.

However, considering the numerous areas of abnormal temperatures and the limited duration of the shutdown period, it was not feasible to completely replace the refractory materials in all the abnormal areas. After discussions with the manufacturer, it was decided to apply the coating only to the areas of the furnace walls exposed to flame impacts.
