What are the Differences between Ramming Material and Castable Material?

What is the difference between ramming material and casting material? First of all, these two products are unshaped refractory materials. The ramming material is constructed by ramming and hardened by heating. The castable is constructed by pouring and harden without heating. What is the difference between ramming material and casting material? The difference lies in the construction method and the hardening method. When buying ramming materials and castables, you must first distinguish the difference between ramming materials and castables.

Definition of Ramming Material and Castable Material

1. Ramming material. The ramming material needs to be mixed on site and rammed with a pneumatic pick or machine, and the wind pressure is not less than 0.5MPa. The parts with less material or unimportant use can also be knotted manually.

It is made by mixing refractory aggregates, powders, binders, admixtures, water or other liquids with a certain grade. Therefore, the inner lining of refractory ramming material has low moisture content and dense knots, and its 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 they tend to be replaced by dry vibrating materials and high-quality refractory castables.

2. Castable material. Castables are generally cast by pouring, shaking or tamping on site. It can also be used as a prefab.

Application and Classification

What is the difference between ramming material and castable? The castable has high fluidity and a wide range of applications. The ramming material, the parts with less material or not important to use, can also be knotted manually. Ramming materials are classified according to materials: high alumina, clay, magnesia, dolomite, zirconium and silicon carbide-carbon refractory ramming materials. The classification of castables is divided into dense refractory castables and heat insulating refractories with porosity not less than 45% according to the porosity distribution. According to the bonding agent, there are hydraulic bonding, chemical bonding, and cohesive bonding refractory castables.

Castable is currently the most widely produced and used unshaped refractory material. It is mainly used for the construction of integral refractory linings such as various heating furnace linings. It is used in the lining of kilns and heating equipment in metallurgy, petroleum, chemical, building materials, electric power, machinery industries, and also in smelting furnaces.

The ramming material is made of silicon carbide, graphite, electric calcined anthracite as raw materials, mixed with a variety of ultra-fine 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. The ramming material has good chemical stability, erosion resistance, abrasion resistance, peeling resistance, heat shock resistance, and is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries.
