Product Description of Rongsheng Refractory Factory Supply High Alumina Corundum Spinel Fused Ramming Mass For Industrial Kilns And Furnaces
Rongsheng Refractory Ramming Mass is a type of unshaped refractory material created through a ramming process (either manual or mechanical) and then solidified by high-temperature heating. It can be formulated in acid, neutral, or alkaline varieties.
The Ramming Mass utilizes premium high-alumina, corundum, and spinel, along with fused and high-purity magnesite as its primary raw materials. Various binding agents and specially selected fine powders are added, following a precise formulation and mixing process.
Types of Refractory Ramming Mass
Aluminum-magnesia ramming material, high-alumina (or corundum) – silicon carbide – carbon ramming material, alkali refractory ramming material and zirconium mullite ramming material.
Rongsheng Refractory Ramming Mass Features
1.On the face in contact with liquid metal there is a dense sintered layer where tightness of liquid metal is quite perfect.
2.Thermal conductivity is lower than other refractoriness so the Thermal loses are less than any other kind of refractory.
3.Good resistance to temperature change.
4.Low cost in furnace lining.
5.Short heating and sintering time through dry preparation Of masses.
6. Strong resistance to erosion.
Refractory Ramming Mass Applications
Refractory Ramming Mass is primarily used for lining the furnaces of boilers, blast furnaces, hot blast stoves, heating furnaces, ceramic kilns, and various industrial furnaces.
It is suitable for a wide range of materials, including carbon steel, low manganese steel, alloy steel, alloy cast iron, high-speed tool steel, and stainless steel.
