Refractory Ramming Mass

The difference between refractory ramming mass materials and other unshaped refractory materials is that there is more powder and less binder in compostion. Soft clay is usually added to the ramming material to increase viscoplasticity and sintering properties.

Kerui Superior Ramming Mass

Introduction of Kerui Refractory Ramming Mass

As we know from the name, refractory ramming mass refers to the monolithic refractory product that uses ramming method in construction. This product has similar compositions with other products, but it saves more energy. Refractory ramming materials are formulated from a high proportion of granular and powdery materials and a low proportion of binders and other components. Some ramming monolithic refractories are even composed entirely of granular and powdery materials, which are bulk materials that need to be constructed by strong ramming.

Because the ramming materials are mainly used in direct contact with the melt, the granular and powdery materials must have high volume stability, density and corrosion resistance. Those used in induction electric furnaces should also have insulation properties. Because of its unique construction method, we can also call this product as ramming compound.

Properties of Kerui Refractory Ramming Mass for Sale


Kerui produces the high quality and premix refractory ramming mass with a superior level of plasticity. Because we incorporate high-quality refractory clay into the mix of high temperature mortar, which provides excellent plasticity. This characteristic facilitates easy and efficient installation so that this material can be molded and compacted with precision during construction.

Chemical Stability

It’s worth noting that the formulation of Kerui refractory ramming mass can withstand chemical erosion effectively. After construction, the material demonstrates remarkable chemical stability, ensuring durability and longevity even in environments prone to chemical attacks. This property is particularly crucial in applications where resistance to corrosive substances is paramount.

Wear Resistance

During the ramming process and following constrcution process, the wear resistance of Kerui ramming material exhibits outstanding durability against abrasive forces. This property contributes to the longevity and sustained performance of refractory linings, especially in high-impact environments. Customers can use this product to face strong mechanical strength.

Thermal Shock Resistance

In applications such as various kiln openings, where thermal shock is a prevalent concern, Kerui ramming mass is an ideal choice. Its inherent thermal shock resistance ensures reliable performance in the face of rapid temperature fluctuations. The good sealing properties make it a good choice for environments with rapid temperature change.


Kerui ramming mass can firmly adhere to the refractory kilns and firebrick liners. Its robust anti-stripping properties ensure that the material remains securely fixed, which resists peeling or detachment during the intense heat and mechanical stresses associated with high-temperature operations. This contributes to the overall integrity of the refractory lining.


With a high density, Kerui Refractory Ramming Mass exhibits elevated refractoriness, making it suitable for applications with temperatures ranging between 1450 to 1700℃. The dense structure enhances its ability to withstand extreme heat conditions, which makes it a reliable choice for industries requiring stable and enduring refractory solutions.

Application of Refractory Ramming Mass

Linings of High Temperature Equipment

As a lining for high-temperature equipment, the excellent performance of Kerui refractory ramming materials makes it suitable for linings of various shapes. Common applications include the lining of blast furnaces, slag trenches, cupola furnaces, ladles, electric arc furnaces, room temperature furnaces, induction furnaces, converters, tapholes, rotary kilns and other kilns.

Sealing Material of High Temperature Equipment

One of the excellent properties of rammable refractory is the flexibility. Besides, it has a good sealing effect in the application of all kinds of doors or export of high-temperature equipment. In the lining of furnaces, kilns, and reactors with refractory blocks, ramming mass can be utilized to seal gaps between refractory bricks or other lining materials. This helps in creating a continuous and effective barrier against heat loss.

Tips for Construction of Refractory Ramming Mass

  • Construction method: manual ramming, air hammer ramming or machine ramming. Additionally, the thickness of each pounding and adding material is about 50-100mm.
  • Temperature requirement: workers can use the refractory ramming materials at room temperature. For example, thermoplastic organic materials that can form carbon bonds are used as binders. Moreover, most of them are constructed immediately after stirring in a hot state. After molding, workers use different heating methods according to the hardening characteristics of the mixture. The method promotes hardening or sintering.
  • Demolding of ramming mass: for ramming materials containing inorganic chemical binders, workers can easily remove and bake the molds after hardening to a certain strength. Moreover, it’s convenient to demould these materials that contain thermoplastic carbon binders after cooling to the appropriate strength. Workers should heat the ramming mass quickly to carbonize after demolding and before use. If you want to know more useful tips about monolithic refractory, welcome to follow Kerui Pinterest.
  • Sintering of ramming linings: the sintering of refractory ramming linings can be carried out in advance before use. Besides, it’s available by heat treatment using a suitable thermal regime when used for the first time. The baking and heating system of ramming materials varies according to different materials.
  • Other uses: the main use of ramming materials is to cast smelting furnace linings that are in direct contact with the melt, such as blast furnace tapping hooks, steelmaking furnace bottoms, induction furnace linings, electric furnace tops, and rotary kiln blanking parts. In addition to forming an integral furnace lining, customers can also use this product to manufacturer large-scale prefabricated components.
