The sintering and dust-removing process of metallurgy is an important and necessary processing process, and also belongs to the sintering process. In the current Metallurgical industry, the development of sintering and dust-removing process technology is increasingly mature, and it is of great significance for improving the economic efficiency of the industry, reducing pollution and reducing energy consumption.
The sintering and dust-removing process is mainly composed of a series of physical and chemical processes, such as crushing, balling, sintering, purging and dust collection. The basic principle of the process is that when fine powdery material is processed under specific physical and chemical conditions, the component particles accumulate, adhere and deform and are fixed in a unique shape through diffusion and fusion, so that they can form agglomerates, macromaterials and even certain shapes of products.
First of all, sintering and dust-removing process uses good ore, coal and other raw materials, and firstly through the crushing equipment, broken particles of these materials, and then through the balling equipment and other equipment, with other components mixed and mixed, into a certain shape, such as nodular or strip blocks, this shape is called a ball. Then the ball must be sintered. This sintering process is usually composed of preheating, drying, roasting, sintering and cooling stages, and a series of strong airflows pass through these large or small metal cages or slotted double rollers, which can completely remove the surface moisture of the ball so as to have a certain strength, and produce further chemical reactions, such as heat and water vapor, so that the particles can be fused together.
These sintered particles can then be broken down by blasting, screening and other processes. The principle of dust removal and purification is to take advantage of the fact that the particle size and specific gravity of dust are different from those of air, and to use this difference to make the dust enter into different dust removal devices to complete purification, dust collection and sintering and dust removal.
The process of sintering and dust-removing process not only reduces the dust content of the emitting gas, but also reduces the thermal damage to the hot gas on the furnace surface, thus ensuring the stability of the hot gas temperature in the lue and the metallurgical reaction at the same time. The whole process of sintering and dust-removing process technology is an important principle of environmental protection and reducing pollution, and its development is also an important direction in the metallurgical industry.
In short, the sintering and dust-removing process is an important link in the whole process of metallurgical production. It not only guarantees the product quality, but also conducts the process in a safe way, which not only improves the economic efficiency of the industry, but also greatly reduces the pollution of the environment, so it has a very important role in the industry. Therefore, the development of sintering and dust-removing process technology has become an important development direction in the metallurgical industry.
