Method for manufacturing tamping material

The tamping material is a bulk material, made of silicon carbide, graphite and electrically fired anthracite as raw materials, mixed with various additives of ultrafine powder and fused cement or composite resin as a binder. Used to fill the gap between the furnace body cooling equipment and the masonry or masonry leveling layer. The ramming mass has good chemical stability, resistance to erosion and wear.

Classification of tamping materials

Tamping materials are classified by material: high-alumina, clayey, magnesia, dolomite, zirconium and silicon carbide refractory materials for tamping.

Characteristics of the tamping material

Compared with other shapeless fireproof materials of the same material, the ramming mixture is dry or semi-dry and loose, and a dense structure can be obtained by vigorous packing. Only when heated to the sintering temperature will the mixture have strength.
After forming the ramming mass, various heating methods can be applied, promoting its hardening or sintering in accordance with the solidification characteristics of the mixture. If it contains inorganic chemical binder, it can be removed from the mold after hardening to a certain strength and baked; if it contains thermoplastic carbon mixture, it must be cooled to a certain strength before molding, and it should be heated quickly, to allow it to coke before use.; Binder, which hardens at room temperature is often sintered using a mold after compaction.

How to use tamping compound?

Preparation

Clean and inspect the construction site, to make sure, that the surface is smooth, clean and free of debris and old materials.

Prepare the necessary construction tools and equipment, such as tamping machines, tamping sticks, forms, etc..

Preparation of tamping material

1. Accurately weigh and mix the required raw materials according to the requirements of the tamping material formulation.
2. In the mixing equipment, mix the powdered raw materials evenly, binder and appropriate amount of water or wetting agent until a homogeneous paste is obtained.

Construction process

1. Using a spatula or spatula, distribute the tamping compound evenly over the surface of the construction site.
2. Use a tamping stick or tamping machine to compact and compact the tamping mass.. Purpose of Tamping – remove voids, increase compactness and ensure strong adhesion of the tamping material to the base.
3. Depending on the needs of the construction process, molds can be used to give parts certain shapes or bends..
4. Check the construction site, to make sure, that the thickness and uniformity of the ramming mass meet the requirements.
