Information

What is the difference between ramming material and castable? Alumina ramming mass manufacturer tells you that these two products are unshaped refractory materials. The ramming material is constructed by ramming and hardened by heating. The manufacturer of Alumina ramming mass tells you that the castable is constructed by pouring and harden without heating. The difference lies in the construction method and the hardening method. Please see the details below.

Definition of ramming and pouring

1. Ramming material, mix the ramming material on site, use a pneumatic pick or mechanical ramming, the wind pressure is not less than 0.5MPa. The manufacturer of Alumina ramming mass tells you that if the amount of material is small or the parts that are not used are not important, it can also be knotted by hand.

The manufacturer of Alumina ramming mass tells you that it is made by mixing refractory aggregates, powders, binders, admixtures with water or other liquids with a certain gradation. Therefore, the inner lining of refractory ramming materials has low moisture content, tight knots, and performance is better than refractory castables of the same material. The disadvantages of refractory ramming materials are slow construction speed and high labor intensity, and there is a tendency to be replaced by dry vibrating materials and high-quality refractory castables.

2. Castables. Castables are generally cast, vibrated or tamped at the site of use, and can also be made into preforms for use.

Application and classification

The manufacturer of Alumina ramming mass tells you that it has a wide range of applications with higher fluidity, less ramming materials or unimportant parts, and you can also use manual knotting. Ramming materials are classified according to their materials: high alumina, clay, magnesia, dolomite, zirconium and silicon carbide-carbon refractory ramming materials. Castables are classified according to their materials:

1. According to the porosity distribution, there are two types of dense refractory castables and thermal insulation refractories with porosity not less than 45%;

2. According to the binder, there are hydraulic bonding, chemical bonding, and cohesive bonding refractory castables.

Castable is currently the most widely produced and used unshaped refractory material. The manufacturer of Alumina ramming mass tells you that it is mainly used to construct various heating furnace linings and other integral structures. It is used in metallurgy, petroleum, chemical, building materials, electric power, machinery industry kilns and heating equipment, and high-quality products can also be used for smelting. furnace.

Alumina ramming mass manufacturer tells you that the ramming material is made of silicon carbide, graphite, electric calcined anthracite as raw materials, mixed with a variety of superfine powder additives, and fused cement or composite resin as a binder. It is used to fill the gap between the furnace cooling equipment and the masonry or the filler for the masonry leveling layer. Alumina ramming mass manufacturer tells you that the ramming material has good chemical stability, erosion resistance, abrasion resistance, spalling resistance, heat shock resistance, and is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries.
