The wear-resistant lining of the conveyor requires a variety of raw materials in the production process, especially the addition of an iron element, because the iron element can help the heating of the wear-resistant plate without deformation, and can also strengthen the resistance of the wear-resistant plate. Pressure capacity. But how should this iron element be added?
The wear-resistant lining treatment process of the conveyor is mainly divided into physical treatment process, wet treatment process, fire treatment process and high value-added utilization process of iron-containing wear plate. At present, the fire-resistant process is mainly used to treat and recycle the wear-resistant lining of the conveyor. The main methods are sintering method, pellet method, dust blowing method, direct reduction method, smelting reduction method and block-return steelmaking method.
The sintering method and the pellet method mainly use the wear-resistant lining of the conveyor as raw materials directly into the sintering and pellet production process. These two methods are the simplest, and can realize the recycling of iron resources to a certain extent, with less investment and quick effect. No need to change the original process and other advantages. The dust blowing method mainly involves mixing iron-containing dust and carbon-containing dust into a blast furnace or other melting furnace in a certain proportion, and replacing some raw materials for recycling and recycling, thereby achieving the purpose of reducing the production cost of iron making.
