Control device for iron ore storage hopper gate according to sintered ore fraction

摘要

The present invention relates to a device for controlling the gate (Gate) of the iron ore storage hopper according to the fraction of the sintered ore made in the sinter plant ganeseol storage hopper of the blast furnace plant, more specifically the sintered ore analysis data of the sintering plant to the steel mill host computer ( 20-1) and the sintered ore particle size analysis value transmission unit for transferring the data to the blast furnace central monitoring chamber 21 using a business computer 60, and the particle size analysis value of the transferred sintered ore is a blast furnace process It is connected to the computer 21-1 and connected to an electrical signal controller (ECC) 21-2 to convert it into an electrical signal.;m Logic Controller (21-3), the input and output processing unit of the signal, the drive motor 30 and the shaft number for controlling the iron ore storage hopper gate 12-1 of the blast furnace plant according to the particle size analysis value ( 31, gear couplings 30-2 and 30-3 and reduction gears 30-4 are installed, and a plurality of sprockets 30-9 and chains installed in the iron ore storage hopper gate 12-1. 30-8) and the electrical pulse value generated by the encoder 30-6 installed on the shaft 31 through the electrical signal input processor of the PLC input / output device 40-1. A sintered light fraction control unit for controlling the gate 12-1 installed at the lower end of the iron ore storage hopper using a drive motor control panel (MCC) 40-7 according to the fraction of the sintered ore, and the electrical signal communication controller 21-2. Auto control amount display part 40-3, manual so that operators can operate regardless of the fraction in the monitor 21-5 of The present invention relates to a control device for an iron ore storage hopper gate according to a sintered light fraction of a smelting furnace, characterized in that it comprises a remote manual operation unit provided with an operation unit 40-4.;By inputting the sintered fraction input data according to the present invention as described above, the iron ore storage hopper gate is automatically controlled in accordance with the fraction of the sintered ore, so that the iron ore can be charged into the furnace at a uniform particle size, and thus, the air permeability defects and the instability of the furnace are unstable. Can be prevented in advance, and excessive generation of small sintered ore can be prevented, thereby preventing the unbalanced small sintered light storage tank and the level rise of the storage tank, thereby reducing the workload.
