The Difference between Mash Materials and Castable Materials in Construction Methods

1. The difference between mash materials and castable materials in construction methods

Pouring materials refer to on-site construction, which is mainly formed by pouring, vibration, or tamping methods. Fixed models can also be prepared in advance and ready for use. The use is more convenient, as long as the proportion specifications during the construction process are paid attention to.

When used on site, high-aluminum ramming materials are mainly rammed with pneumatic picks or machines, and the wind pressure is not less than 0.5MPa. When less materials are used, the materials can also be fed manually. Relatively speaking, the construction operation without castables is simple, and the ramming intensity needs to be controlled.

2. Differences in raw materials

Pounded materials are mixed with aggregates, powders, binders, and additives and can be divided into graphite, clay, silicon carbide, and magnesium.

Castables are made of refractory materials with fixed binders and additives. They have high fluidity and are divided into main components and additional components. Subdivisions can also be divided into refractory castables such as lightweight castables, high-aluminum castables, corundum castables, and steel fiber castables. Better and richer performance than pounded material.

3. Different applications under specific application conditions

Although mash materials and castables can be used in metallurgy, petroleum, chemical industry, building materials, electric power, mechanical industrial kilns, etc., their specific applications are different. Castables play a dominant role in the construction process and are mainly used to construct various heating furnace linings and other overall structures. Some castables can even be used in smelting furnaces, cast during construction, or performed in advance.

The mash acts as a filler and supplement. It is a bulk material made of silicon carbide, graphite, and electrically calcined anthracite as raw materials, mixed with a variety of ultrafine powder additives, and fused cement or composite resin as a combination agent. It is used to fill the gap between the furnace cooling equipment and the masonry. Gap or masonry screed. During specific construction, attention should be paid, the intensity should be uniform, and the construction should be smooth.
