Abstract
The utility model relates to an aluminum feeding device for an electroslag furnace. According to the aluminum feeding device, aluminum powder is fed into a crystallizer through an aluminum feeding inlet; the aluminum feeding device comprises an aluminum powder hopper and a blanking pipe, wherein the bottom of the aluminum powder hopper is conical, the upper end of the blanking pipe is fixedly arranged at the lower end of the aluminum powder hopper. The aluminum feeding device is characterized in that the blanking device is a first blanking pipe, a transiting aluminum powder hopper and a second blanking pipe are further arranged, and the bottom of the transiting aluminum powder hopper is conical; the first blanking pipe is perpendicular to a horizontal plane, and the lower end of the first blanking pipe extends in the transiting aluminum powder hopper; the upper end of the second blanking pipe is fixedly arranged at the lower end of the transiting aluminum powder hopper, the second blanking pipe is perpendicular to the horizontal plane, and the lower end of the second blanking pipe extends to the upper side of the aluminum feeding inlet. The transiting aluminum powder hopper is connected together with an electrode trolley arranged above the aluminum feeding inlet, and the axial distance between each of the first blanking pipe and the second blanking pipe and the aluminum feeding inlet in a horizontal direction is less than the radius of the aluminum feeding inlet. According to the aluminum feeding device for the electroslag furnace, plugging of the blanking pipes due to accumulation of the aluminum powder can be avoided.
Description
Technical field
The utility model relates to a kind of electroslag furnace and adds aluminium device, and particularly 5+5 electroslag furnace is with adding aluminium device.
Background technology
It is the visual plant that electroslag furnace adds aluminium device that electroslag furnace adds aluminium device, the conveying that existing electroslag furnace adds aluminium device is crooked for tremie pipe, aluminium powder is defeated by crystallizer from tremie pipe under the effect of deadweight, in tremie pipe knee, aluminium powder drops to herein, easily assembles agglomeratingly, adds high temperature action, aluminium powder fusing is stuck with paste in knee, causes aluminium powder to join in crystallizer.
Summary of the invention
The above-mentioned deficiency that adds aluminium device in order to overcome existing electroslag furnace, the utility model provides a kind of avoiding to pile up and cause the electroslag furnace of tremie pipe obstruction to add aluminium device because of aluminium powder at tremie pipe.
It is that aluminium powder is added to and adds aluminium device in crystallizer by adding aluminium mouth that this electroslag furnace adds aluminium device, it comprises aluminium powder bucket and tremie pipe, the bottom of aluminium powder bucket is taper, the upper end of tremie pipe is fixed on the lower end of aluminium powder bucket, it is characterized in that: described tremie pipe is the first tremie pipe, transfer aluminium powder bucket and the second tremie pipe are also being set, and the bottom of transfer aluminium powder bucket is taper; The first tremie pipe lower end vertical with horizontal plane and the first tremie pipe puts in transfer aluminium powder bucket; The upper end of the second tremie pipe is fixed on the lower end of transfer aluminium powder bucket, and the second tremie pipe is vertical with horizontal plane, and the lower end of the second tremie pipe reaches the top that adds aluminium mouth.
The electroslag furnace of the above adds aluminium device, it is characterized in that: transfer aluminium powder bucket links together with being arranged on the electrode dolly that adds aluminium mouth top position, and the first tremie pipe and the second tremie pipe are less than to the axial line distance that adds aluminium mouth the radius that adds aluminium mouth in the horizontal direction.
This electroslag furnace adds aluminium device at a transfer aluminium powder bucket of the other increase of electrode dolly, and tremie pipe is kept vertically constantly, has prevented the phenomenon that knee aluminium powder is piled up.
Accompanying drawing explanation

In above-mentioned figure
1-aluminium powder bucket, 2-the first tremie pipe 3-electrode dolly 4-dummy electrode
5-consumable electrode 6-add aluminium mouth 7-crystallizer 8-transfer aluminium powder bucket
9-union lever, 10-the second tremie pipe 11-aluminium powder.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, describe embodiment of the present utility model in detail, but embodiment of the present utility model is not limited to following embodiment.
Embodiment
The structure of the present embodiment is shown in Fig. 1, it is that aluminium powder 11 is added to and adds aluminium device in crystallizer 7 by adding aluminium mouth 6, and electrode dolly 3 is arranged on dummy electrode 4, and dummy electrode 4 is arranged on consumable electrode 5, consumable electrode 5 is adding on aluminium mouth 6, adds aluminium mouth 6 on crystallizer 7 and is fixed as one.This electroslag furnace adds aluminium device
Comprise aluminium powder bucket 1 and tremie pipe, the bottom of aluminium powder bucket 1 is taper, and the upper end of tremie pipe is fixed on the lower end of aluminium powder bucket 1, it is characterized in that: described tremie pipe is the first tremie pipe 2, transfer aluminium powder bucket 8 and the second tremie pipe 10 are also being set, and the bottom of transfer aluminium powder bucket 8 is taper; The first tremie pipe 2 lower end vertical with horizontal plane and the first tremie pipe 2 puts in transfer aluminium powder bucket 8; The upper end of the second tremie pipe 10 is fixed on the lower end of transfer aluminium powder bucket 8, and the second tremie pipe 10 is vertical with horizontal plane, and the lower end of the second tremie pipe 10 reaches the top that adds aluminium mouth 6.
The electroslag furnace of the above adds aluminium device, it is characterized in that: transfer aluminium powder bucket 8 links together with being arranged on the electrode dolly 3 that adds aluminium mouth 6 top positions, and the distance that the first tremie pipe 2 and the second tremie pipe 10 are horizontal direction to the axial line distance that adds aluminium mouth 6 is in the horizontal direction less than the radius that adds aluminium mouth 6.
This device adds to aluminium powder 11 in the first tremie pipe 2 by aluminium powder bucket 1 in use, aluminium powder 11 adds to by the first tremie pipe 2 the transfer aluminium powder bucket 8 that is fixed on electrode dolly 3 under Gravitative Loads, aluminium powder 11 adds to aluminium powder 11 in the second tremie pipe 10 again by transfer aluminium powder bucket 8, and aluminium powder 11 adds to aluminium powder 11 in crystallizer 7 by adding aluminium mouth 6 by Gravitative Loads.
One end of the union lever 9 of the present embodiment is welded on transfer aluminium powder bucket 8, and the other end is welded on electrode dolly 3.Transfer aluminium powder bucket 8 also can be otherwise with being connected and fixed of electrode dolly 3.
By the enforcement of this programme, can improve low-oxygen steel (take RG20Cr2Ni4A as example) oxygen level qualification rate, improve approximately 10% lumber recovery.Take RG20Cr2Ni4A as example, 17000 yuan/ton of finished products, 6000 yuan/ton of steel scraps, by producing 1000 tons of calculating per year,
1000 * 0.1 * (17000-6000)=110 ten thousand yuan.
