Description

Bucket device for transporting special alloy steel of converter

The present invention is designed to quickly transfer special alloys (Nl, V, Cr, P ‥‥) into the converter during the steelmaking process of the converter to refine molten iron into molten steel. It relates to a bucket (BUCKET) device used for transporting and feeding the special ferroalloy of the converter for the introduction of ferroalloy.

In general, the special alloy steel input operation of the conventional converter, as shown in Figures 1 and 2, the special alloy (m) input of the converter is a steel ladle 19 through the input chute 18 during tapping In this case, the basis weight of the special alloy iron (m) is scaled down to the lower part of the special alloy iron hopper of the corresponding product name among several storage hoppers (1a, 1b, 1c ...). After moving, the alloy (m) is fed to the scale car (7) by a feeder (3) that provides electrical vibration (vibration force), and the special alloy iron weighted to the scale car (7) Is loaded by opening the gate 6 of the scale car 7 in the drum 13 provided in advance below the scale car (7).

In addition, the special alloy iron (m) contained in the drum barrel 13 on the pallet 12 is transported around the input chute case 16 by using a forklift, and loaded on the floor (floor), the worker shovels (14) ) And the special ferroalloy is introduced into the inlet opening 17 of the closing chute case 16.

However, in the transportation and input operation of the conventional special alloy iron as described above, as shown in FIGS. 1 and 2, the worker's fatigue increases rapidly and a large amount (1500-2500 kg) of special alloy iron is applied. In the case of inputting, due to the characteristics of the converter tapping work, it is not possible to complete all the inputs of the special alloy iron during the tapping time of 4-5 minutes, and thus the special alloy iron is taken because the addition of the alloy iron is performed even after the tapping work is completed. It floats on the surface of the molten steel of the ladle and causes the quality of molten steel due to unbalanced components or non-uniformity of molten steel, and through the two-stage work step of loading the expensive special alloy iron on the floor and re-injecting it. As a result, the loss of ferroalloy is severe, while the input cost of ferroalloy is increased, and above all, the transfer of special ferroalloy between workers is carried out. In the process, due doemeuro weighting is physical fatigue action, there is a tendency to avoid the operation was a disadvantage that the inefficiency and the work will of operation failure.

In addition, there was a number of problems, such as harmful to the human body of workers due to long exposure in high working temperature and dust during the operation and input of special alloy iron.

The present invention has been devised to solve various problems as described above, the purpose of which is to transport and inject the special alloy steel during the transfer operation work, by using the bucket input device for transporting, the work load of the worker This improves the efficiency of the work by improving the efficiency of the work, and improves the productivity of the overall converter work by smoothly transporting and inputting the special alloy steel, and prevents the segregation of molten steel caused by the delay of the input of the special alloy steel. The present invention provides a bucket device for transporting special alloy iron in a converter which achieves an improvement and promptly injects special alloy iron to improve workability and worker safety.
