Products Description

Dry ramming mass is also called ramming mix. There are wet ramming mass and dry ramming mass. Magnesite ramming mass is generally dry ramming mass

Types: Silica ramming mass, high alumina ramming mass, magnesia ramming mass and corundum spinel ramming mass are supplied. High purity raw materials are applied.

Application: furnace bottom for EBT furnace and direct current arc furnace;working lining of induction furnace; lining of tundish; Torpedo or transfer car

Installation method:Ramming or vibrating.

Monolithic refractories refers to unshaped refractories. It could be moulded or can be given any shape as per requirement.

Monolithics consists of graded refractory aggregates, binding agent, fillers & special additives for modification of properties

Aggregates of monolithic refractories generally include kaolin flint, high alumina bauxite, tabular alumina, white fused alumina, dense mullite, dead burnt magnesite etc. Aggregates are main contents of monolithic, they are mixed according to certain proportions in different particle size.

Binding agent are different for different monolithic refractory. For alumina castable, it's generally high alumina cement, water or Sodium silicate. For plastic refractory, Phosphate acid is generally applied. For magnesite ramming and gunning mass, Boric acid is widely used as binding agent.

By adopting the dry ramming mass, the material particles are made finer and more uniform, and after compression molding, it has high strength and high temperature resistance characteristics, and is widely used in high temperature industries, such as steel, glass, cement and other industries.

Dry ramming refractory mass have many characteristics and advantages that traditional refractory materials do not have. First of all, due to the way of dry ramming mass, the material particles can be made finer and more uniform, and the product density is higher, so it has higher strength and better durability.

In addition, dry ramming refractory mass have better high temperature resistance and slag corrosion resistance after compression molding. At the same time, its appearance is relatively exquisite, without defects such as burrs and holes, which can effectively improve efficiency and quality.

Products Applications

Refractory dry ramming masshave a wide range of applications, not only in the construction industry, but also in steel, metallurgy, chemical industry, electric power and other fields.

First, it is widely used in the construction industry. Refractory materials in the construction industry are mainly used in various high-temperature furnaces, industrial furnaces, blast furnaces, smelting furnaces, chemical furnaces and other equipment, and refractory dry ramming mass can be widely used in the repair and reinforcement of these equipment.

Secondly, the steel and metallurgical fields are also one of its application places. Because steel and metallurgical production often require high-temperature and high-pressure equipment, a large amount of refractory materials are needed to assist production. As one of the auxiliary materials, dry ramming mass is widely used. It can greatly help this field to produce high-quality steel and other metallurgical materials.

Thirdly, it is also widely used in chemical industry, electric power and other fields. In the chemical industry, dry ramming mass can be used for internal repair and external fixation of various heating equipment and reactors. In the power industry, it can be used for internal repair of burners and other equipment, thereby improving the efficiency and service life of the equipment.
