Problems solved by technology

During the sintering production process, it takes 30 minutes to discharge the material from the batching chamber to the mixing tank, but because the design volume of the mixing tank can only maintain the sintering machine’s material consumption for 5 minutes, when the adjusted delivery volume of the batching room reaches the mixing In the trough, the change in the material level of the mixing trough due to the change of the machine speed has caused the empty or full warehouse, resulting in fluctuations in production

Abstract

The invention discloses a control method for balancing the amount of material distributed on the table top of a sintering machine, which adopts the method of maintaining a stable total amount of mixed material feeding and adjusting the frequency of round rollers to realize the stability of the warehouse position of the mixed material, so that the amount of material distributed on the table surface of the sintering machine can be accurately controlled ; When the height of the flat material plate and the speed of the machine are stable, it is the control of the compactness of the sintering table. Using the above technical solution, the mixed material bin is controlled by adjusting the frequency of the round rollers; using data analysis tools, it is possible to match different machine speeds with different feeding amounts, avoid frequent fluctuations in the total amount of feeding, and facilitate the control of sintering output , to stabilize the slot position of the blast furnace; through the precise control of the degree of compaction and the use of data analysis tools, it is possible to find the best matching effect among the feeding amount, machine speed and negative pressure for different ore batches; through the machine speed uniform change program , avoiding the unevenness of the amount of material on the sintering table caused by adjusting the speed of the machine.

Description

technical field [0001] The invention belongs to the technical field of sintering production process control, and in particular provides a control method for stabilizing the amount of material distributed on the table surface of a sintering machine by equalizing the flow rate of the mixed material. Background technique [0002] The sintered material is discharged from the batching room, mixed and granulated by the mixer and added with water, buffered in the mixing silo, and then evenly stacked on the sintering machine trolley by round rollers and nine-roll distributors (or reflectors) for ignition combustion. The role of the mixing bin in the sintering process is to buffer the material and ensure the balance of the bin in the bin, which is the key factor to ensure the quality of the sintered product and the smooth operation of the production process. As a result, the sintering machine is on standby due to lack of material at normal speed. [0003] When the speed of the sint...
