High Purity of Raw Materials

Kerui utilizes high-purity materials such as Al2O3, SiO2, and MgO, which ensures the quality and performance of all kinds of refractory materials. The use of such pure raw materials contributes to the excellent properties and durability of their products. Furthermore, Kerui benefits from its strategic factory location, which is surrounded by abundant mineral resources specifically used in refractory production. This proximity to essential raw materials allows Kerui to maintain a continuous and reliable supply of high-quality inputs. By having easy access to these resources, Kerui can ensure the consistency and reliability of their dense castable refractory.

Precise Proportions

Moreover, Kerui precise formulation process also contributes to the excellence of their dense castable refractory. They employ a fully automated batching system and a PLC control system, ensuring accurate and consistent proportions of the different raw materials. This meticulous approach to formulation guarantees the desired properties and performance of their castable refractory products. By maintaining strict quality control throughout the manufacturing process, Kerui can deliver refractory products that meet the highest industry standards.

Types of Dense Castables for your Reference

On the basis of high density, Kerui supports customized castable composition and other properties. Here are several types of castables for your reference. It is worth noting that the division here is mainly based on raw materials. Of course, you can also contact Kerui for custom production of dense castables.

Instructions for use: Mix with a small amount of water, pour into the mold and press slowly to ensure there are no air pockets. Wait to cure and dry. Heating should be gradual before reaching operating temperature. It’s worth noting that drying too quickly can cause cracks, shortening its service life.

Bulk Density of Refractory Castable

Bulk density is an important parameter to consider when it comes to refractory castables. It refers to the ratio of the dry mass of the castable to its total volume. The density of the castable has a significant impact on its overall performance and other properties such as porosity, load softening temperature, and thermal shock resistance.

In general, higher bulk density in refractory castables is associated with increased strength, corrosion resistance and load softening temperature. This means that castables with higher bulk density are more capable of withstanding high temperatures and harsh environments. Refractory castables 1700c with high bulk density are often used in environments that are subjected to high temperatures and molten slag. The increased density helps to enhance the castable’s strength and resistance to corrosion, which makes it suitable for such conditions.

The choice of dense castable refractory and its bulk density depends on the specific application and operating conditions. It is important for customers to determine the appropriate refractory castable type based on their specific requirements and environment. If you are unsure about which type of refractory castable is most suitable for your product, feel free to contact us at Kerui.
