Abstract
A kind of charge level jack sintering method is before pallet enters sintering oven, jack on the charge level in chassis, and this jack operation is advisable with jack devices, comprises electric motor, transmission rig, eccentric wheel and guide way thereof, the hub machine of vent needle and support body.After the charge level jack, ignition area and burning area strengthen, and excessive moistening layer moves down and speeds up, and has quickened sintering velocity, and moisture retention is less, and ventilation property improves, and the output and the quality of agglomerate production are improved.
Description
The present invention relates in the raw-material preprocessing process of a kind of metallurgical industry the method that material stoking agglomeration is produced.
In the sintering for agglumeration production process; traditional theory is thought; deep-bed sintering can improve the quality of product; the agglomerate that is used for metallurgical production preferably; the inside and outside the sector in native land has mostly adopted the sintering method of the thick bed of material; on the thickness of the bed of material, formed competition trend; wherein Ri Ben enterprise has reached more than 600 millimeters; adopt this method; consequent problem is: zone of combustion broadens very slow with excessive moistening layer thickening sintering process; water evaporates is detained; cause ventilation property to worsen; the output and the quality of agglomerate have also been influenced from another point of view; fine grinding concentrate proportioning increases gradually in recent years; give and make the sizable difficulty of spherical zone; influenced the popularization of the thick bed of material to a certain extent; for above-mentioned all because of thickening the practical problems that the bed of material brings to SINTERING PRODUCTION; enterprise with good conditionsi or just in enterprise that technical application is transformed; all adopt grate-layer material; double-layer cloth and install the way that loose metal mechanism etc. improves the ventilation property of the middle and lower part bed of material own additional; but these ways are subjected to the restriction of factors such as original layout and investment, are very limited in utilization.
The purpose of this invention is to provide a kind of deep-bed sintering production that is applicable to, investment is little, and is simple and easy to do, the agglomerate production of general enterprise had the charge level jack sintering production method of obvious positively effect.
The concrete implementing process process that can realize the charge level jack sintering production method of above-mentioned purpose is: in the agglomerate production process, pallet enters before the sintering oven, jack on charge level, the aperture is 10 millimeters of ∮ 3～∮, actually operating is as the criterion can form the entire body turbulent flow, the degree of depth in hole is thick 1/2～1/10 for material, and line-spacing is 5～50 millimeters.
This charge level jack operation is operating as suitable with hub machine, hub machine comprises motor and transmission rig, vent needle and support body, eccentric wheel and guide way thereof.Belt transmission in the transmission rig mainly changes to consider gets rid of the overload factor that foreign matter causes in the material, because the diameter of vent needle is less relatively, it curves the limited flexibility of structure and vent needle self, also can achieve the above object.Moving up and down of vent needle and support body relies on eccentric wheel to realize.
Fig. 1 is a charge level jack sintering production method synoptic diagram;
Fig. 2 moves towards synoptic diagram for aforesaid method along chassis;
Fig. 3 is that each band of sintering production method compares synoptic diagram before and after the jack;
Fig. 4 is the hub machine schematic diagram.
Among the figure: 1, electric motor 2, stepless speed regulation step-down gear 3, adhesive tape and belt wheel 4, chain 5, sprocket wheel 6, axle 7, bearing 8, eccentric wheel 9, eccentric wheel guide way 10, vent needle 11, vent needle support body
Below in conjunction with accompanying drawing in detail the present invention is described in detail: among the figure, example has gone out in the sintering production method of jack front and back, combustion zone, preheating zone, the comparable situation of crossing wet band and mixing the bed of material. Not during jack, after the igniting, from top to bottom, the distributed combustion band, preheating zone, excessively wet band and the mixing bed of material, this distribution is that whole surface area descends in proper order, and the area of ignition and combustion is littler, and sintering is slow, water evaporates is detained, thereby concentrate on the bottom, affected gas permeability, cause output and quality and the Quality Down of sintering deposit. After the jack, above-mentioned surface area increases, the area of ignition and combustion also increases, and the deep of the bed of material is separated, at the deep ignition and combustion, towards periphery expansion, cause a kind of gesture of three-dimensional ignition and combustion, sintering velocity is accelerated greatly, and combustion zone, preheating zone, excessively wet band Fast synchronization descend, water evaporates is very fast, in addition because The compartmentation in hole can't be detained moisture content or less delay, does not affect gas permeability, has improved output and the quality of sintering deposit.
Verified the present invention compared with prior art based on the sintering cup test of above-mentioned sintering mechanism, its outstanding effect is:
1, behind the jack, the degree of roughness of charge level increases, and preheating, ignition area increase relatively, the igniting heat is absorbed corresponding increasing by the top bed of material, thereby improved bed of material top sintering deposit yield rate, excessive moistening layer and burning zone have been moved down speed up, accelerated sintering process.
2, owing to increased the igniting degree of depth, the igniting heat can make full use of, and helps finishing in advance excessive moistening layer, has reduced the ruined degree of bead in the excessive moistening layer, for sintering for agglumeration has been created condition.
3, because vertical sintering speed is accelerated and yield rate improves, utilization coefficient is improved.
