Refractory ramming material is one of the common amorphous refractory materials, named after the construction method is ramming. Often used at the bottom of a kiln. What are the common refractory ramming materials in the ironmaking and steelmaking metallurgical industry? Rongsheng refractory material manufacturer, based on many years of experience in the production and sales of refractory materials, can provide concentrated and high-quality refractory ramming materials.
Tap trough refractory ramming material-aluminum silicon carbide carbon refractory ramming material
When lining the tap trench where molten iron flows in the ironmaking blast furnace tapyard, aluminum silicon carbide carbon refractory ramming material can be used. The pounded iron trench lining can be put into use without baking. It is made of fused corundum, graphite carbon, and silicon carbide as the main refractory raw materials, adding binders according to the formula proportion, and mixing and stirring.
Characteristics of tap trough refractory ramming material:
- High compressive strength under high-temperature environment.
- Strong plasticity.
- Strong resistance to slag erosion and erosion resistance.
Tundish refractory ramming materials – magnesia ramming materials and silica ramming materials
The refractory ramming materials in the middle layer of the steelmaking tundish include magnesia ramming materials and siliceous ramming materials. Magnesia ramming materials are made of sintered magnesia or fused magnesia as the main refractory raw materials, with low-temperature binders and additives added according to the formula proportions. Siliceous dry ramming material uses quartz refractory raw materials as the main ramming material aggregate. Add powder, additives, and binding agents, and stir evenly.
Magnesia refractory ramming material for steelmaking electric furnace bottom
The magnesia refractory ramming material at the bottom of the steelmaking electric furnace has good resistance to erosion and erosion by molten steel slag, has a dense sintered layer, long service life, and low consumption per ton of steel.
Refractory ramming materials have certain limitations due to construction methods, so they are mostly used at the bottom of thermal equipment. The ramming layer of the ramming material is dense and can resist slag erosion effectively.
What are the Differences between Ramming Material and Castable Material?
First of all, these two products are unshaped refractory materials. The ramming material is constructed by ramming and hardened by heating. The castable is constructed by pouring and harden without heating. What is the difference between ramming material and casting material? The difference lies in the construction method and the hardening method. When buying ramming materials and castables, you must first distinguish the difference between ramming materials and castables. RS High-Quality Ramming Mass Material.
Definition of Ramming Material and Castable Material
- Ramming material. The ramming material needs to be mixed on site and rammed with a pneumatic pick or machine, and the wind pressure is not less than 0.5MPa. The parts with less material or unimportant use can also be knotted manually.It is made by mixing refractory aggregates, powders, binders, admixtures, water or other liquids with a certain grade. Therefore, the inner lining of refractory ramming material has low moisture content and dense knots, and its performance is better than refractory castables of the same material. The disadvantages of refractory ramming materials are slow construction speed and high labor intensity, and they tend to be replaced by dry vibrating materials and high-quality refractory castables.
- Castable material. Castables are generally cast by pouring, shaking or tamping on site. It can also be used as a prefab. SiC Wear-Resistance Ramming Material.
