Metallurgical ore powder briquette is a new type of furnace charge introduced in recent years. Because of its environmental protection and energy-saving characteristics in the production and use process, it is widely used in iron and steel, and ferroalloy enterprises instead of lump ore for smelting. The preparation of metallurgical pellets is an important part of the metallurgical process, which can not only improve the metallurgical physical and chemical properties of materials but also realize the resource utilization of industrial solid waste and an important way of the circular economy. Therefore, pelletizing technology is an important way to realize energy saving, environmental protection, and utilization of waste resources. The cold-pressed pellets prepared by this technology are also used as a burden for blast furnaces, direct reduction furnaces, cupola furnaces, and submerged arc furnaces.
