Description
Technical Field
The utility model relates to a pine glassware technical field specifically indicates a spiral pine material device for sintering.
Background
In the sintering process of the iron ore, the air permeability is an important operation parameter, the air permeability of the whole material layer is good, the fuel in the material layer can be fully combusted, more heat is released, the quality of the sintered ore can be ensured, the fuel consumption can be reduced, and the generation of pollution gas is reduced. The main loosening device at the present stage is formed by welding thicker steel bars on a baffle plate of the trolley and plays a role in loosening the materials by utilizing the length and the diameter of the device, and the method has two main defects that the diameter of the steel bars is thinner, so that the whole material layer is difficult to loosen, and the change of the pressure of the material layer from top to bottom is not considered, so that the air permeability of the lower part is obviously lower than that of the upper part. These disadvantages lead to non-uniform air permeability of the whole material layer, and local high temperature is generated during sintering, so that the sintered ore is locally melted, the hardness is higher after cooling, in addition, under-burning phenomenon occurs at the place with poor air permeability, and the pulverization rate of the sintered ore is higher. This directly results in high energy consumption and more impurities in the blast furnace smelting process.
SUMMERY OF THE UTILITY MODEL
