Description
Technical field
The present invention relates to the comprehensive utilization to various available thin the material material that can join in converter.
Background technology
Available fine granular materials etc. are generally difficult to be directly loadable into converter, and its Land use systems currently mainly has several as follows: one, return sintering, make raw materials for sintering and use.This technological requirement sintering plant has special batching equipment, sintering plant need adjust dispensing parameter according to supplied materials in good time, SINTERING PRODUCTION is had interference, and circulating path is longer, especially with metallic iron component return sintering Value Loss bigger；Two, after available fine grained material being processed balling-up, converter is added by high hopper.This technological process is approximately as: fine grained material → Zhi Qiu factory → dispensing → mixing → pressure ball → dry → transport → steel mill → ground feed bin → elevator → conveyer belt → high hopper → converter, this technological process circulating path is longer, relatively costly, steel-making is had impact by the binding agent that additionally balling-up uses.
Summary of the invention
Problem to be solved by this invention is to provide the method that fine granular materials metering adds converter, and fine granular materials according to steel-making needs, can be allocated into steel scrap bucket in good time, pour converter together with steel scrap into by it.The inventive method makes fine granular materials be directly added into converter, and not only circulating path is short, be fed into during stove that airborne dust is little, added value is high, profitable, and fine grained material to enter stove also helpful to steel-making early stage slag making.Invention also provides supporting device so that can join in converter for fine granular materials.
The method that fine granular materials of the present invention metering adds converter, it concretely comprises the following steps: 1) dumper pours fine granular materials into feed bin；2) fine granular materials is released from feed bin and is dropped on underground transportation rubber belt after the metering device of material outlet；3) the boosted device of fine granular materials, overhead conveyer belt are sent to portable discharger；4) fine granular materials on portable discharger is poured in steel scrap bucket；5) fine granular materials of steel scrap bucket is poured in converter together with steel scrap.
Wherein, in step 2, the metering of fine granular materials is by computer control, and the reinforced master control of fine grained material is arranged together with the reinforced master control of steel scrap, it is simple to unified dispensing.
Fine granular materials of the present invention metering adds the device of converter, it includes the stocking system of fine grained material, metering system, induction system, stocking system includes several ground feed bins, vibra feeder and metering device are set in the exit of each feed bin, equipped with underground conveyer belt below feed bin, the lower of lifting device is arranged on below conveyer belt one, its eminence is arranged on the lower section of overhead conveyer belt, equipped with portable discharger on overhead conveyer belt, portable discharger be connected with steel scrap bucket.
The inventive method makes fine granular materials can join with measuring in corresponding steel scrap bucket by corresponding device, under ensureing the premise of setting of fine granular materials and steel scrap ratio, pours in converter.Instant invention overcomes present by high hopper feed, due to the impact of its air exhauster, fine granular materials cannot join the shortcoming in converter so that it is under the premise not having loss of material, the recycling of material with the shortest path implement.
Accompanying drawing explanation
Fig. 1 is the device that fine granular materials of the present invention metering adds converter.
Detailed description of the invention
The method that fine granular materials of the present invention metering adds converter, it concretely comprises the following steps: 1) dumper pours fine granular materials into feed bin；2) fine granular materials is released from feed bin and is dropped on underground transportation rubber belt after the metering device of material outlet；3) the boosted device of fine granular materials, overhead conveyer belt are sent to portable discharger；4) fine granular materials on portable discharger is poured in steel scrap bucket；5) fine granular materials of steel scrap bucket is poured in converter together with steel scrap.
Wherein, in step 2, fine granular materials is vibrated by the vibra feeder of material outlet when releasing from feed bin, so can ensure that fine granular materials is all released.
As a kind of optimal way of the present invention, in step 2, the metering of fine granular materials is by computer control, and the reinforced master control of fine granular materials is arranged together with the reinforced master control of steel scrap, it is simple to unified dispensing.Fine granular materials different in step 1 is poured in different feed bins.In step 4, fine granular materials is poured in corresponding steel scrap bucket, to ensure the layout of fine grained material and steel scrap ratio.
Operating process is as follows: steel-making master control determines fine granular materials classification and quantity according to smelting steel grade, molten iron condition, steel scrap condition, steel scrap master control is by steel-making master control requirement, steel scrap bucket is put into below fine granular materials discharger, start fine granular materials charging system, the fine granular materials needed is put into steel scrap bucket anterior.
Thin of present invention material material metering adds the device of converter, it includes the stocking system of fine granular materials, metering system, induction system, stocking system includes several ground feed bins 2, steel scrap bucket 8, metering system is metering device 3, induction system includes underground conveyer belt 4, lifting device 5, overhead conveyer belt 6, vibra feeder and metering device 3 are set in the exit of each feed bin 2, equipped with underground conveyer belt 4 below feed bin 2, the lower of lifting device 5 is arranged on below conveyer belt 1 one, its eminence is arranged on the lower section of overhead conveyer belt 6, equipped with portable discharger 7 on overhead conveyer belt 6, portable discharger 7 be connected with several steel scrap buckets 8.
Wherein, ground feed bin 3～7, it is used for storing classifiedly return fine granular materials.Steel scrap bucket 3～7, for the classification that corresponding fine granular materials is different.
Fine granular materials is by pouring (varigrained granule enters different feed bins) in ground feed bin 2 into toward dumper 1, the fine granular materials that feed bin 2 is released is through underground transportation rubber belt 4 → lifting device 5 → overhead conveyer belt 6 → portable discharger 7, load steel scrap bucket 8, pour converter together with steel scrap into.Reinforced process is by computer control, and the reinforced master control of fine grained material is arranged together with the reinforced master control of steel scrap, it is simple to unified dispensing.
