래밍 재료는 유도로의 충전 재료입니다.

Refractory ramming material refers to an unshaped refractory material that is constructed by ramming (manual or mechanical) and hardened under heating above normal temperature. It is made by mixing refractory aggregates, powders, binders, admixtures with water or other liquids. Classified by material, there are high alumina, clay, magnesia, dolomite, zirconium and silicon carbide-carbon refractory ramming materials.

Silicon, graphite, electric calcined anthracite as raw materials, mixed with a variety of fine powder additives, fused cement or composite resin as a bulk material made of binder. It is used to fill the gap between the furnace body 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!

The mineral composition of quartz sand composite ramming material: it is made of quartz, ceramic composite binder, fused quartz, impermeable agent and other materials. It has the following characteristics after being verified by many enterprises of large tonnage and small tonnage:

1) The sintered layer is thin;

2) 열효율을 향상시킨다.

3) 고온에서 물리적, 화학적 변화가 작다.

4) 우수한 보온 성능;

5) The lining has good pore density and small expansion coefficient;

6) 전기 및 열전도율이 작다.

7) 표면 구조는 강도가 좋고 균열이없고 박리가 없습니다.

8) 안정적인 볼륨, 부식 방지,

9) 부식 방지;

10) 긴 수명.
