Does everyone know what dusting ash is?

 Do you know what the dust ash is?

  Steel mill dust and mud resources containing iron is the waste of the metallurgical industry, and its iron content is up to 45%. Some steel mills discard the dust and mud, and some companies recycle it as sintering raw material. This simple and low-tech recycling leads to waste of labour materials and energy consumption, repeated pollution and inevitably reduces production efficiency.

  Dedusting ash is made of polymer environmental protection material, which has the characteristics of strong adhesion, high moulding rate, good cold compression strength, fast curing speed, anti-disintegration, anti-chalking, cost reduction and environmental protection. It is specially used for dusting ash containing calcium oxide, sludge, iron oxide skin, sintered return ore and other iron containing wastes. It does not take up too much space, simple process, low investment in equipment, low production cost, so that the pellet ore has enough strength to return to the furnace to make steel and iron.

  Characteristics of dusting ash:

  1. Dedusting ash is white solid powder, which is made of organic matter and various chemical raw materials through chemical reaction and physical methods. It is non-corrosive and does not contain harmful elements such as sulphur and phosphorus;

  2. It is suitable for iron and steel mills to deal with the moulding of iron containing dust waste, and can also be used for the moulding and agglomeration of mineral powder, instead of cooling scrap steel, ore or slagging agent, with high alkalinity, low melting point, fast slagging speed, stable composition, good slagging effect, and metallurgical properties to meet the requirements of smelting furnace for mechanical strength and high temperature strength;

  3. The dust ash does not need to add bentonite and other auxiliary materials, does not reduce the grade of pelletised ore, avoids digestion of raw materials, avoids sintering, avoids drying, and is formed into a ball at one time, which saves smelting solvents and energy consumption.

  4. Simple production process: one tonne can produce 30 tonnes of pellet ore, which is made of ore powder, dust sludge, binder and water directly mixed and stirred proportionally, and the yield is as high as 95%. Wet ball more than 1 metre high will not fall down, fast solidification speed, high strength. The wet ball can be stacked for 5-7 days and then put into the furnace for melting.

  5 Dust removal ash has the advantages of fast solidification, small area, stacking balls for 3-5 hours, and evolving smelting in the iron furnace for 5-7 days. 850 or so high temperature without cracking.

  With the growing iron and steel production capacity, iron ore demand is rising, the contradiction between supply and demand is increasing, and environmental protection requirements are becoming more and more stringent. The secondary recycling of fly ash, sludge and steel slag is of great significance, which can not only reduce the production cost and increase the output, but also solve the problem of environmental pollution and alleviate the shortage of resources. The economic and social benefits are very obvious.

 Dusting ash is of great significance to the comprehensive utilisation of metallurgical resources, and provides a more feasible way for dusting ash ball-making technology, which has a broad prospect in the production of iron and steel industry.
