Abstract
Description
More particularly, the present invention relates to a bogie capable of preventing weight measurement error, and more particularly, to a bogie capable of preventing an error in weight measurement, and more particularly, The present invention relates to a bogie capable of preventing a weight measurement error that can prevent a weight measurement error due to a load and a control method thereof.
Electric arc furnace work is done by supplying arcing power and arcing with scrap. Scrap, which is the main material, is buried in the bay, so the scrap is put into the basket using the magnet, Is moved to the upper part of the electric furnace and the loop is opened to charge the electric furnace.
In order to load the scrap into the basket, the magnet is moved to a bay selected by the work instruction sheet among a plurality of raw materials to be picked up by a magnet, and then is loaded into the basket.
At this time, in the course of loading the scrap into the basket, scrap (1 to 3 tons) of heavy weight is dropped to the basket at a height of about 7 to 8 m. At this time, an impact is applied to the load cell disposed under the seating base, There is a problem that a weight measurement error is caused by changing load cell characteristics.
When the input raw material is precisely weighed and charged into the electric furnace, it is possible to carry out the quality control by performing accurate work according to the standard. However, when the amount of raw material is different from the intention of the operator due to the measurement error of weighing, Quality control is impossible and the cause is an unclear quality defect result.
In addition, in the process of charging the scrap into the electric furnace and placing the empty basket on the seat base, a weight of about 35 tons is applied to the seat base, and as a result, the shock is transmitted to the load cell, It is true.
Conventionally, in order to solve the above-mentioned problem, when an operator inserts scrap into a basket, he tries to drop the magnet from the bottom of the basket as much as possible. However, It can not be prevented. In addition, there is a problem that the admission work is delayed at the time of the operation, and the operation result is different according to the worker's condition and the operator's condition. In addition, when the empty basket is put on the seat base, there is no other way and the driver tries to put it as carefully as possible. However, it is impossible to prevent the impact due to the function of the worker because the work is performed without ensuring the upper field of view of about 30 m. The impact on the cell is continuously applied, and the weight measurement error continues to occur due to such a problem.
The embodiments of the present invention can prevent the impact load from being applied to the load cell formed under the mounting base for placing the basket in the process of loading the scrap into the basket in the scrap loading process of the electric furnace working process, Which can prevent the weight measurement error that can prevent the weight measurement error.
Embodiments of the present invention also provide a method for controlling the bogie.
A bogie that can prevent a weighing error according to an embodiment of the present invention includes a bogie main body, a seating base for seating a basket disposed on the bogie main body, a support base disposed between the bogie main body and the seating base, A load cell for measuring the weight of the basket mounted on the load cell and a load cell arranged adjacent to the load cell and supporting the load base between the load body and the load base, And an error preventing cylinder that enables measurement error prevention.
