How to properly apply ramming mix

Ramming material refers to the construction by ramming (manual or mechanical) method. Ramming material is made by mixing particles, powder, separating agent, admixture with water or other liquids. According to the material, there are high alumina, clay Quality, magnesia, dolomite, zirconium and silicon carbide-carbon refractory ramming materials.

Among them, the ramming material is made of silicon carbide, graphite, and electro-calcined anthracite as raw materials, mixed with various ultra-fine powder additives, and a block material made of electro-fused cement or composite resin as a binder. Filling furnace cooling equipment Filler for gaps between masonry or masonry leveling layer. Ramming material has good chemical stability, corrosion resistance, wear resistance, peeling resistance and thermal shock resistance. Widely used in metallurgy, building materials, non-ferrous metal processing , chemical, machinery and other manufacturing industries.

Today, Luoyang Quantong Kiln Industry Co., Ltd. will take you to understand the construction method of the coating and introduce the ramming material:

a: During construction, use a hammer or rubber hammer to tamp. When smearing or tamping, check the thickness of the fabric at any time, requiring uniform thickness and smooth appearance. Then wipe the smooth surface with a spatula. It is forbidden to brush water, grout or sprinkle dry on the surface cement.

b: During the construction of the tortoiseshell mesh structure fabric, the area of ​​the lining material filled with the tortoiseshell mesh should not be too large each time, and it should be filled one by one, so that the surface of the fabric is flush with the tortoiseshell mesh. During continuous construction, the unconstructed part of the tortoise shell mesh should be removed. residual material inside.

c: According to the construction requirements, set expansion joints, and fill the expansion joints with refractory fibers.

After the construction is completed, it should be naturally cured for 3 days at room temperature, and it is strictly forbidden to use water. The maintenance temperature should be as much as possible above 20 degrees Celsius. When the ambient temperature is lower than 20 degrees Celsius, depending on the hardening situation, the curing time should be appropriately extended or other corresponding measures should be taken .
