Description

Blast furnace air supply blowpipe positioner

Technical Field

The utility model relates to the technical field of positioning devices, in particular to a positioning device for a blast furnace air supply blowpipe.

Background

The positioning device is used for determining the position required by a workpiece or a processing tool, and the blast furnace air supply system is defined as that under a certain smelting condition, proper air blowing parameters and air inlet states of an air port are determined, so that the air quantity is increased, and the comprehensive smelting strength is improved. Under the condition that the fuel ratio is reduced or the fuel ratio is kept unchanged, the air quantity is increased, the blanking speed is accelerated, and the pig iron yield is increased. The air quantity should be reduced in time when the material speed exceeds the normal regulation. When the blast furnace has material hanging, material collapsing or low material line, the wind is timely reduced and the required level is reduced at one time. When the slag iron is not discharged completely, the air reduction should be carried out by closely paying attention to the condition of the tuyere so as to prevent the tuyere from being filled with slag. When the furnace condition is changed to be smooth and wind needs to be added, the blast furnace can not be put in place at one time, and the smooth damage of the blast furnace is prevented. The two air additions should have a certain time interval. The coke ratio can be greatly reduced by increasing the air temperature. The temperature of the air is increased to increase the kinetic energy of the blast air, the temperature of the hearth is increased to activate the hearth to work, the initial distribution of the coal gas flow is promoted to be reasonable, and the effect of injecting fuel is improved. The wind pressure directly reflects the adaptation condition of the gas in the furnace and the air permeability of the material column.
