Description

A flux automatic supply system for ingot continuous casting

The present invention relates to a flux automatic feeding device for ingot continuous casting, and more particularly to flux in a mold and a friction part so that hot water molten metal can be smoothly injected into a mold in an ingot continuous casting process. It is to provide a flux automatic feeder for continuous ingot casting which greatly improves the function of the flux automatic feeder that automatically supplies).

Typically, continuous casting of steel is an intermediate product production technology that has been introduced worldwide since the 1960s, and has many advantages over the general ingot method, and currently accounts for more than 60% of the world's crude steel production.

Especially in Japan, Korea and Western Europe, more than 90% of the ingots are produced by this continuous casting technique.

Since the continuous casting method has been continuously developed and new technology has been developed since the initial invention, since this casting method is already well-known technology, a detailed description thereof will be omitted.

In addition, the continuous casting method is published in Korea Patent Publication No. 1997-61401 (continuous casting method), Publication No. 1997-73800 (continuous casting method and apparatus) and Publication No. 1998-87531 (continuous casting of steel) Device).

On the other hand, the continuous casting device described above is necessarily provided with an automatic supply device that can supply the flux of the powder-type lubricant to the ingot casting mold.

In other words, in order to continuously inject the molten metal when casting the ingot continuously, the flux is sprayed on the part rubbed with the mold,

As a representative technology for such a flux automatic feeding device, Korean Patent Laid-Open Publication No. 90-700213 (Powder Feeding Device in Continuous Casting) is disclosed.

The patent discloses a powder container for accommodating the final casting powder supplied on the molten steel surface in a mold, and a metering feeder system for injecting the casting powder onto the molten steel surface in the mold. The vessel is placed above the mold's workspace and the above described metering fida system is attached to the manipulator, and the opening of the metering fida system and the powder container can follow the operation of the manipulator. The trajectory is connected via a path,

This patent is characterized in that it can automatically perform the flux supply that was made by conventional manual work, but also had a number of problems at the same time.

1. There is a disadvantage in that the flux is transported by air, and water is contained in the flux, so that the flux is fixed in the pipe and thus a blockage occurs.

2. Since Manipulator is only folded up and down, the method of discharging the flux is very limited. Also, the final powder container connected to the Manipulator is rotated around the column. In this case, the space occupancy inevitably increased.

3. The metering filament system has a problem that the particle size of the flux is broken by friction with the screw-type spring, so that a large amount of fine dust is generated at the time of final discharge, and in particular, the particles of the flux are broken and cannot function properly. There was also.

4. The robot arm is provided on the upper side, and the robot arm operates up, down, left, and right, and the tilting method is composed of a chain structure.

5. The operation of the manipulator was always up and down, left and right, while maintaining the horizontal level, causing the accumulation of flux in the transfer, there was a disadvantage that the transfer is not performed smoothly.

In the present invention to solve the problems that the existing flux automatic supply device as described above,

The present invention in the flux automatic feeder for continuous ingot casting, it is possible to more smoothly transfer the flux from the feed hopper to the manipulator,

In the feed hopper, the flux is inclined and can be supplied to the mold through the manipulator and the mating feeder to prevent the accumulation of transfer in advance.

Ingot continuous casting flux for precise control of the mating feeder by providing a servo unit consisting of a servo motor to control the left and right and up and down operation of the mating feeder, and to provide improved performance. The present invention has been completed in view of the technical problem of the present invention in providing an automatic supply device.
