Abstract
The invention relates to a method for introducing bulk material into a metallurgical vessel, especially for introducing scrap into an arc furnace, which has at least one centrally situated electrode in an upper vessel part that is gas-tightly sealed by a lid. The bulk material is transported to the head of the metallurgical vessel in individual bulk material containers. The opening part of the bulk material container is connected to coupling parts of the lid. The bulk material is conveyed out of the container by conveying parts connected to the bulk material containers and introduced into the metallurgical vessel by access openings in the lid. In the case of a device that is suitable for carrying out this method, at least one ring-shaped part of the lid is rotationally connected to a lid drive system in the lid plane. The rotating lid part has at least one feed opening, through which the bulk material can be conveyed into the upper vessel part. The feed openings are covered by coupling parts which have a sealable wall. A bulk material container which can be filled with bulk material can be coupled with the coupling part. The bulk material container is connected to a conveying unit by which means the bulk material can be conveyed into the metallurgical vessel through the lid part, through the feed opening.
Description
The present invention relates to bulk cargo adding metallurgical furnace and especially the method in the iron and steel scrap adding electric arc furnace, described electric arc furnace has the electrode that at least one is arranged on the center in the stove top with the airtight sealing of lid, the invention still further relates to its corresponding device thereof.
Normally charging by batches of metallurgical furnace, thus feed to electric arc furnace with waste tank regularly.
Known a kind of steelshop device sealing and tipping electric arc furnace that has from EP0646652B1, this electric arc furnace has a loading machine that has at least two tanks.These tanks are arranged on the both sides of electrode support arm and are fixed on the hanging scaffold of workshop.Tank has a removable bottom in the charging process.Can't utilize these containers to feed continuously to stove.
DE19753184A1 has described a kind of smelting furnace device that is used for smelting metal, wherein is provided with a pipe core abreast with the stove main shaft, is provided with at least one electrode and can be placed on a container on the burner in this pipe core.In this container, furnace charge temporarily is deposited on the stove that is sealed by lid and by the bell opening and is fallen in the stove.In this known devices, also can't give charge of stove continuously.
DE4407861C1 discloses a kind of electric arc furnace feeder, wherein is provided with an annular chamber on bell,, is provided with a running gear here in annular chamber, can be suspended on this running gear by anastomosing lifting magnet.At least one materials conveyance mechanism stretches in the stove from the side, and the lifting magnet that is fixed on the running gear is arranged in this materials conveyance mechanism, and lifting magnet can be by take furnace charge and furnace charge thrown on the optional position in the stove of magnetic force.Carry material to be undertaken to stove by endless apron.This is not equal in batches working by independent bulk container.
Task of the present invention provides a kind of method and device in the bulk cargo adding metallurgical furnace, and it is sent to bulk cargo burner in batches and can adds stove top to bulk cargo continuously by simple structural measure reliable operation ground.
The present invention has finished this task by the feature of method independent claim 1 and device independent claim 4.
According to the present invention, adopted separate bulk material device in order to be sent to metallurgical furnace as known gravity discharge chute in steelworks, as what in converter steelmaking, adopted.
The lid on sealing metallurgical furnace top is designed to be rotating and to have at least one opening.Be provided with a docking mechanism in the open area, it links to each other with a bulk container that iron and steel scrap is housed.When lid rotates, send bulk cargo from container.By this method, in the annular degree of depth district of each arbitrfary point, obtained to be arranged in the furnace charge on stove top.
Carrying out transferring out from bulk container bulk cargo controllably, exactly, is by by the slide plate material casting, carries or the entire container of toppling by conveying belt.By using independently chute, improved working reliability and reduced iron and steel scrap and taken up an area of requirement.In addition, when a bulk container broke down under it is installed in situation on the burner, its function can be born by another container.In addition, can be on the position of accident occurring another container be packed in the loading area.Therefore, can in a maintenance area of separating, wait container and the especially fault of transfer mechanism driving mechanism that may occur.
Except slide plate electronic or that drive with fluid motor, also can be conveying belt and the vibratory sluice that drives by any way as transfer mechanism.
In a favourable improvement project, bulk container is placed on the support, this support cause vertical and perhaps the bulk cargo angle on the level attitude change.By mechanism and/or the tilting mechanism of toppling, can so regulate bulk container, the bulk cargo of promptly also can in inapproachable stove upper area, packing into.In this case, can constitute bulk container in simplicity of design ground.
In a particular design scheme, in burner, be provided with the measuring and adjusting mechanism of measuring occupied state, wherein control the discharge rate of lid rotation and transfer mechanism by computer.
Bulk container is placed in respectively in the docking mechanism, and they have guaranteed metallurgical furnace charging free from environmental pollution by the suitable seal lath.In a favourable improvement project of the present invention, elastic support sealing lath.
According to the present invention, these bulk containers can be docked on the lid on any position.
In first design, bulk container is placed on the circular lid along diagonal, and wherein bulk container is not projected into outside the lid edge at when filling with substance.
In second design, have only the chute of bulk container prominent, and the major part of vessel faces is projected into outside the lid edge to lid.In this design, can be docked at obvious container on the burner more than one., provide at least two docking mechanisms here, because so not charging continuously interruptedly.
Stipulated that in another favourable design can be docked at least three bulk containers on the burner, wherein these containers move along a straight line along the tangential extension of charging bole medullary ray.Thus one, these containers are projected into outside the lid edge hardly, and thus one, even if a bulk container breaks down, also can load metallurgical furnace continuously.
An example of the present invention shown in the drawings wherein schematically shows:
Fig. 1 shows has the stove that is installed in the bulk container on the rotatable lid;
Fig. 2 shows has two outwards stoves of outstanding bulk container;
Fig. 3 shows the electric arc furnace with a Docking station;
Fig. 4 a-Fig. 4 c is the vertical view that dwindles of stove and bulk container arrangement.
Fig. 1-Fig. 3 shows metallurgical furnace respectively, and it is the electric arc furnace form here, and described metallurgical furnace has a furnace bottom 12 and a stove top that is covered by a lid 15.Lid 15 or annular cap 16 are rotatably supported in by roller 19 on the opening on stove top 11 and by a lid rotating drive mechanism 51 and are driven.
