Introduction of Kerui Refractory Precast Products for Sale

There are great advantages in using refractory precast blocks in high temperature kilns. Such as its consistent and controlled manufacturing process, faster construction speed and good fire resistance. In addition, the weight of shapes can also range from tens of kilograms to several tons. Therefore, they can also be divided into small, medium and large shapes. Furthermore, some shaped refractory plastic products have steel bars or anchors added inside.

Here we take the most common precast block for your reference.

Advantages of Kerui Refractory Precast Blocks

No Limit on Application Area

Generally speaking, the shape, size and quantity of precast refractory shapes are customized according to customer needs. Although some parts of the high-temperature kiln have special shapes, you can still use them normally. These blocks can withstand extreme temperatures. These products are suitable for a wide range of industrial processes. Whether you need to line furnaces, kilns, reactors or any other high-temperature equipment, it can be customized to fit your specific needs.

Long Service Life

Kerui refractory precast products can be cast and manufactured by selecting appropriate raw materials according to the location of the equipment and the working temperature. The main materials are of high purity. The refractories and monolithics can withstand the harsh conditions of high-temperature applications. Besides, they maintain structural integrity and the longevity reduces the need for frequent maintenance or replacement. Customers can realize cost savings and increased productivity for industrial operations.

Convenient Masonry

The production of refractory precast blocks is mainly done by refractory material manufacturers. During the production process, prefabricated components will complete pouring, curing and drying in advance. In this way, there are fewer problems with on-site construction time and explosions that may occur when the kiln heats up quickly.

No Limit by Environment

After the successful production of refractory precast shapes, customers can install and use them directly in all kinds of high temperature equipment. Some monolithic refractory products are not suitable in high or low temperature. There is no limit on seasons and environments. Therefore, you can use this excellent product at any time.
