Steel forgings improve the internal structure and mechanical properties of the forgings during the forging process. Therefore, forgings have high mechanical strength, are not easy to break, and improve toughness. They are generally used in parts that require large stress, or parts with harsh working environments, such as gears or engine shafts. In addition to improving mechanical properties, forging has the advantages of high utilization of materials and high productivity. For some parts that require precision assembly or high precision, it can be achieved by secondary precision CNC machining. However, due to the characteristics of the forging process, forging is not suitable for the production of workpieces with complex shapes, or requires a relatively large amount of subsequent CNC machining to achieve products with complex shapes.
For forged parts, the most important are the three processes of mold development, forging processing and secondary precision CNC processing. And these three processes are all completed in-house, we can better ensure product quality and production delivery. We take quality first and service first for our customers.

Followed by the use of spray mist, or foam dust. On the one hand, the direct spray can make the dust particles wet, adhere to each other, agglomerate and grow, and then it is easy to separate in the atmosphere. On the other hand, for the flue gas with higher temperature, the direct spray to achieve evaporative cooling can be made with a small amount of water. Flue gas cooling, volume shrinkage, and speed reduction also contribute to dust removal. Past textbooks and design manuals say that spray dust removal is only suitable for 50? More than m dust, dust removal efficiency is only 40-70%. Practical experience shows that due to the advancement of spray technology, 10 can be removed through the spray system. More than m dust is close to 100%, 1? More than m dust can also remove 90-95%.
Therefore, from the perspective of emission reduction and energy conservation and cost reduction, we must first consider non-powered dust removal and direct spray dust removal. We must consider the third option when we have to be the last resort: we must first consider the low energy consumption when using ventilation and dust removal systems for ventilation and dust removal. The electric dust collector finally considered the bag filter. In this way of thinking, we can reflect on the actual selection sequence of our current dust removal equipment, and we can find some problems worthy of improvement: such as secondary dust removal in converters, dust removal in blast furnaces, loading and unloading of loading and unloading materials, and similar applications. Dust particles are 80% or even 90%. The above are all 10? More than m, but almost the majority of our country adopts ventilation and dust removal, and uses a bag filter to solve the problem of emission reduction, but the operating costs are high; when the converter LT method dust removal unburnt method dust is mostly coarse particles However, the inlet concentration of the electrostatic precipitator is designed to be 70-100 g/m3, resulting in a large electric field and large equipment. Of course, some unstable electrostatic precipitators are also a practical problem that must be solved. 
According to foreign experience, there are three different levels of dust removal equipment choices: the first choice is dust, that is, like all kinds of diseases, prevention is always more cost-effective than treatment, such as loading and unloading, belt transfer when adding a flow channel, you can greatly reduce Dust, or soot generation and processing volume; in the processing of discrete materials such as steel slag, the use of partial airtight, so that the generated dust, dust and dust in the circulation of its kinetic energy, the dust will most of the natural settlement. This kind of mechanical dust-removing and dust-removing is known as non-power dust-removing in foreign countries. Most of the dust in large-scale applications is suitable for non-powered dust-removing.
