Description
Technical field
The invention belongs to field of metallurgy, be specifically related to the control device of a kind of steel works sintering machine trolley both sides rim charge thickness.
Background technology
Along with the development of China's steel and iron industry, natural rich iron ore is in output and all can not satisfies the demand of blast furnace process qualitatively far away, and fine ore and natural rich ore powder that a large amount of lean ore obtains after ore dressing can not be directly into blast furnace processes.For solving this contradiction, people pass through manual method, these fine ores are made block enriched ore, use for blast furnace, so both, we had opened up new approach for utilizing poor iron ore deposit, solved the problem of natural rich ore deficiency, again can be by improving the metallurgical performance of enriched ore, for the steel and iron industry that further develops China has been developed new quality raw materials.
The sintering of iron ore is with various powdery iron-containing raw materials, allocate the fuel and the flux of some on request into, evenly cloth is lighted a fire to agglomerating plant behind the mixing granulation, produces in fuel combustion under the effect of high temperature and a series of physical-chemical reactions, makes the breeze caking of compound.Down draft sintering is that ready raw materials for sintering is passed through distributing device cloth to sintering pallet, igniter is lighted a fire at charge level then, begin exhausting in the time of igniting, form certain negative pressure under the car type furnace grid section, air then enters following bellows by sinter bed from top to bottom.Along with the burning of bed of material surface fuel, combustion zone moves down gradually, when combustion zone arrives fire grate, and the sintering process knot that promptly comes to an end.Sintering process is carried out downwards gradually by the beginning of bed of material surface, thereby is divided into successively from top to bottom along the bed depth direction: sintering ore bed, burning zone, preliminary heating zone, drying layer, excessive moistening layer.
At present, there is more serious edge effect in process of production in domestic sintering machine, and main cause is:
Be subjected to distributing device striker plate and sintering pallet both sides baffle effect when 1, the mixing material is by multi-roller spreader, the mixing material is cushioned, and can not form vertical material-distributing, cause chassis baffle plate both sides bed of material density to compare less with the density of the middle bed of material of chassis, in sintering process, edge effect is more serious, thereby makes the air-flow skewness that passes through sinter bed.
2, the mixing material is by multi-roller spreader cloth to chassis the time, bulk material grain is because good fluidity, roll to sintering pallet baffle plate both sides rapidly, the concentration of local of bulk material grain, produce the particle segregation phenomenon, also make chassis baffle plate both sides bed of material pine, the gas permeability of the bed of material is obviously than the good permeability of the bed of material in the middle of the chassis, thereby causes the phenomenon that tacks.
3, slit, both sides inequality between sintering pallet and the chassis, air leak rate of air curtain increases, and the big local bed of material that gaps is loose, and local bed permeability is good, thereby forms partial flame fltting speed difference.The device that the Chinese patent of being applied for by Wuhan Iron ﹠ Steel (Group) Corp. 200720083395.1 " the sintering pallet baffle plate that suppresses edge effect " is adopted preferably resolves present domestic sintering machine and has more serious edge effect in process of production, but still undesirable.
Because chassis baffle plate both sides bed of material density is compared less with the middle bed of material density of chassis, make the good permeability of the chassis both sides bed of material than the middle bed of material of chassis, the sintering ore bed on both sides forms rapidly, simultaneously at burning zone the liquid phase fused mass appears, produce 1300～1500 ℃ high temperature, because combustion zone is the highest zone of temperature, we call vertical sintering speed to the translational speed of temperature peak in the burning zone, and vertical sintering speed is the key factor of decision sintering deposit output, output and its relation in direct ratio substantially, under certain condition, improving vertical sintering speed sintering deposit output increases, but if vertical sintering speed is too high, will cause sinter strength and decrease in yield, its result has offset the factor of sintering deposit increase of production, and sinter quality is degenerated.
The mixing material by cloth to the chassis of sintering machine, sintering machine slowly moves, through flat glassware mixing material on the chassis is wipeed off, preferably resolved the problem of flat material by the Chinese patent 200320112150.9 " device of smooth sintering pallet charge level " of Handan Iron ﹠. Steel Co., Ltd.'s application.But, interfere mutually in order to prevent flat glassware and chassis, the flat glassware of present domestic use all can not be the same with the sintering pallet width long, the normal now flat materials device that uses all concentrates on the mid portion of chassis, apart from chassis baffle plate both sides 150～250mm is arranged approximately, that is to say that the mixing material of the 150～250mm on chassis baffle plate both sides is nature trickling shape.The effect of the flat materials device of sintering machine has two, and the one, mixing material on the chassis is wipeed off, form the sintering ore bed of consistency of thickness, be convenient to make the sintering air quantity evenly to distribute.The 2nd, the gas permeability of even mixing material, it is long-pending together that flat glassware scrapes stockpile, and mixing material own wt is adjusted the gap between the bulk material grain in the middle of the chassis, makes permeability of sintering material bed reach unanimity at the chassis mid portion everywhere.At present, also there is not a kind of device that the sintering pallet rim charge can be compressed.
Summary of the invention
