What are the 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 use temperature and metal quality. Due to the application of high-quality special mixed powder, the refractoriness and softening temperature under load are improved, and the use temperature can be increased by 50-100 degrees Celsius, and it is lazy, and does not melt with the molten metal below 1700 degrees Celsius. The metal reacts, the loss of metal elements is small, and the quality of the molten metal is stable.

3. Good slag resistance and corrosion resistance. Acid and alkaline slag does not react with the furnace lining, its slag resistance is good, and its erosion resistance is excellent, and the erosion 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 a variety of smelting types. It 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 will form 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 quartz quality, it can replace expensive imported materials, and the price is only 1\/5 of imported materials. It is an ideal furnace construction material for coreless induction furnaces above 1.5T. It will undoubtedly make a certain contribution to the foundry industry. It will also open up a new way for the vigorous promotion and use of various domestic cast irons.
