The semi-wet refractory mixture constructed by the tamping method is called Refractory Ramming Mass Material. Different from refractory plastic, this kind of refractory mixture is a low plastic or non-plastic ramming material, which is formed into a dense body by forced ramming. Then it is hardened by heating or baking and obtains a certain structural strength. In addition to plastic (wet Refractory Ramming Mass Material) and ramming mix material (semi-wet Refractory Ramming Mass Material), the materials used in ramming method construction now also include dry ramming material (ramming material without liquid), a completely non-plastic ramming material.

Classification of Refractory Ramming Mass Materials

Refractory Ramming Mass Materials have many materials and varieties and are used in a wide range. At present, the main varieties of ramming materials are aluminum-magnesium ramming materials, high aluminum (or corundum)-silicon carbide-carbon ramming materials, alkaline refractory ramming materials and zirconium mullite ramming materials, etc.

Application of Various Refractory Ramming Mix Materials

• Aluminum-magnesium ramming materials can be used as integral ramming linings for ladles, induction furnace linings, electric furnace tapping trough linings, and high-temperature containers in contact with high-temperature metal solutions and slag.
• High-aluminum-silicon carbide-carbon ramming materials are mainly used for linings of tapping troughs and slag troughs for medium and small blast furnaces.
• Basic refractory ramming materials are mainly used to build or repair electric furnaces and open-hearth furnace molten pools and tapping troughs.
• Zircon ramming materials are mainly used as bottom linings under zirconium corundum mullite bricks cast in glass kiln molten pools. They can also be used as fillers for expansion joints of silica brick masonry and as transition layer materials between silica and high-aluminum refractory products. And the linings of some induction furnaces and melt launders.

Rongsheng Refractory Material Manufacturer

With the advancement of science and technology, the production conditions of high-temperature industrial furnaces have changed, and more and more types of refractory materials have emerged. It aims to improve the production environment for enterprises, save production costs, and improve economic benefits. Due to the high labor intensity of ramming construction, long construction time, and difficulty in obtaining a uniform overall lining, it has gradually been replaced by amorphous refractory materials with other construction methods. There are not many places using this semi-wet ramming mix material. But Rongsheng Refractory Manufacturer believes that if you need it, we can customize Refractory Ramming Mass material products for you. Whether it is kiln repair or new kiln construction, the Rongsheng Amorphous Refractory Material Manufacturer can provide you with the most cost-saving customized solution for refractory lining materials.
