The present invention relates to a magnetic lifter for transferring coils, and more particularly, to a furnace base in which a cold rolled material from TCM of a batch annealing furnace line is collected, put into a furnace, and heated to produce a desired steel grade. After the coil is deposited, the convector is inserted between the coil and the coil. The magnetic lifter performs a convector difference and extraction operation with a magnetic lifter.

The conventional magnetic lifter has a structure in which a chain is connected to a magnetic cover plate at a hook connecting portion and a magnetic coil part for fastening a coil is fastened to the magnetic cover plate.

Such a conventional magnetic lifter is a lifter for transporting a coil, and when transporting a low-capacity convector, the convector must be transported by finely adjusting the voltage. Even when the coil is loaded, the convector is not separated due to the residual voltage remaining in the magnetic lifter when inserting the convector into the coil, causing frequent delays in work and efficiency degradation.

And when the convector is transported, the convector cannot be separated due to the strong self-adhesive force, so it must wait until the residual voltage disappears from the electromagnet.If the lift power is turned off to remove the residual voltage of the electromagnet to rush the work, The vector falls to the coil side and damages the side surface of the coil, and when the convector is removed, the coil is stuck together and the coil falls.

In addition, the conventional magnetic lifter visually checks the coil center and cannot work, so if the center does not fit and the coil is moved to one side of the lifter due to inconsistency in the center of gravity, it may cause the coil to fall down due to this. When it is applied to the furnace, one part of the coil first touches the lower part of the furnace to damage the coil due to its own weight.The conventional magnetic lifter has a smaller outer diameter than the magnetic lifter because the driver does not see the lower part and works from the air to the neck side. Is covered by the lifter and the center does not coincide, causing the lifter to tilt when hoisting. This causes the edges to break and rewinds from the line and shears the damaged coil, resulting in lowered yield and reprocessing. There is a problem that occurs.

1-1 shows a phenomenon in which coils are self-fixed together when extracting a conventional convector, and FIG. 1-2 shows a phenomenon in which a convector of a claim is not a single convector, and FIGS. 1-3 are coils. This is a situation diagram showing a situation where the edges of the lifters are damaged due to misalignment of the centers of the lifters.

The present invention is to solve the above-mentioned problems, by using the forward and backward operation of the hook block of the convector hook lifter installed in the magnetic lifter to transfer the convectors one by one and using the sensor installed under the magnetic lifter and the multiplex The objective is to provide a magnetic lifter equipped with a centering adjuster and a convector hook lifter to prevent damage to the product and to prevent deterioration by matching the sensor installed under the magnetic lifter.
