Blast furnace gas slag (dust) is a byproduct obtained from the blast furnace smelting process, where raw material dust is carried out with blast furnace gas and smoke particles generated from intense reactions in the high-temperature zone are removed by dust collection. It is one of the solid waste products generated by steel enterprises. With a large steel production capacity in our country, the iron output has been approximately 800 million tons in recent years. Calculating at about 20 kg of blast furnace gas slag (mud) per ton of iron, the annual production will reach 16 million tons. Improper handling not only results in significant resource waste but also, with a zinc content of 10-25%, it equates to 16-40 million tons of metallic zinc, roughly equivalent to the mining of 26-64 million tons of zinc ore. Additionally, it poses a severe impact on the ecological environment, besides occupying a large amount of land resources, it also poses harm to the air, water, and soil, becoming a crucial issue that every steel enterprise must confront.
This adhesive features the following characteristics:
1. This product is easy to store and transport, non-flammable, and affordably priced, with significant usage effects.
2. This product is easy to use, requiring no additional equipment; simply add it directly to the mixture.
3. Add this product initially to the mixture, ensuring thorough mixing, and then add to the appropriate amount of water.
4. As everyone knows, demolding can be a huge challenge in cold pressing. We recommend using elliptical aperture die balls for mold, which makes demolding easier and ensures smooth production.
5. Dosage: Generally 1%-4% of the blend, adjust according to the particle size and performance of the blend. The dosage is significantly lower than that of conventional cold-pressed pellet binder, approximately half of the conventional cold-pressed pellet binder.
6. Benefits: Due to the low addition rate, it ensures minimal impurities introduced into the pellets, effectively preventing a decline in pellet quality, leading to an improvement in pellet grade. This increases the benefit, which is what we aim for.
7. This series of products is not only suitable for cold pressing molding but also for the ball disk ball drying and storage process.
