What are the main advantages of using dry ramming material?

5 advantages of using dry ramming mixes:

1. The batching and stirring process can be reduced, and the furnace can be directly built without additives and water.

2. Improve the operating temperature and metal quality. Due to the application of high-quality special mixed powder, the refractoriness and softening temperature under load can be increased, and the operating temperature can be increased by 50-100 degrees Celsius, and it is inert. Below 1700 degrees Celsius, it does not interact with the molten metal. The reaction occurs, the loss of metal elements is small, and the quality of the molten metal is stable.

3. Excellent slag resistance and corrosion resistance. Acidic and alkaline slag does not react with the furnace lining, its slag resistance is good, corrosion resistance is excellent, and the corrosion rate is only 1\/3 of the quartz charge.

4. It is accustomed to a wide range of coreless induction furnaces of various capacities, and has many smelting varieties, and is accustomed to smelting all kinds of pig iron, carbon steel, especially gray cast iron, ductile iron and other alloy irons.

5. The use efficiency is high, the service life is greatly prolonged, and the furnace age is 2-3 times that of the general quartz furnace lining. It can greatly reduce the number of constructions, reduce manpower, material resources, materials, power, capital consumption and direct production costs, with high socioeconomic benefits.

After the FGD series composite dry ramming material is sintered at an appropriate temperature, the furnace lining forms a certain thickness of sintered layer, semi-sintered layer and loose layer from the inside to the outside. Corrosion, the use temperature is 50-100 degrees Celsius higher than that of quartz, and it can replace valuable imported materials. It will undoubtedly make a certain contribution to the foundry industry. It will also open up a new road for the vigorous promotion and use of various cast irons in China.
