There are great advantages to 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 plastic refractory products have steel bars or anchors added inside.
Here we take the most common precast block for your reference.

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.
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 their longevity reduces the need for frequent maintenance or replacement. Customers can realize cost savings and increased productivity for industrial operations.
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.
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 for high or low temperatures. There is no limit on seasons and environments. Therefore, you can use this excellent product at any time.
Select appropriate raw materials according to the use environment and requirements. Different refractory materials have different characteristics and application ranges. Work with refractory bricks manufacturers to tailor feedstock formulations to specific needs to ensure the blocks have the desired characteristics and performance.
Determine the size and shape of the prefabricated blocks according to the actual application scenario and requirements. Moreover, customers can customize shapes to fit specific shapes or sizes of equipment. Detailed dimensional requirements and drawings are provided to the refractory manufacturer and we will produce these blocks according to these requirements.
Discuss prefabricated block fabrication and delivery times with the refractory manufacturer. Agree on an appropriate delivery time based on the urgency of the project and the supplier’s production capabilities. The manufacturer will produce and arrange shipments according to the negotiated schedule. Now contact Kerui to order the earliest delivery!
It is crucial for refractory precast elements to maintain the same quality as the rest of the structure. This requires high-quality raw materials, consistent molding technology, modern processing equipment, and strict quality control systems. Kerui has a strict quality control system. Moreover, there is advanced manufacturing technology as well as a fully automatic production system to ensure consistent quality for your products.
To meet customer needs, Kerui Refractory Group introduced a fully automated refractory production system. In addition to this, Kerui professional mold design engineers can ensure its precise shape.
