Abstract

PURPOSE:To efficiently and safely feed ingots into a plating tank by conveying plural ingots connected to each other at the connecting parts to a position above the plating tank and by continuously feeding the ingots into the tank with a feeding mechanism sloping down toward the inside of the tank. CONSTITUTION:Plural ingots 1 connected to each other at the connecting parts are conveyed to a position close to a chute 4 and enabling connection to the preceding ingot 1 with a belt conveyor 6. Three ingot 1 are shifted to the chute 4 by the action of a pusher 7 and the chute 4 is inclined by the action of a driving mechanism to drop the shifted ingots 1 into a plating tank 2 through ingot support rollers 9. The chute 4 is then returned to the original position and ingots 1 are successively fed into the tank 3 through the chute 4 in a similar way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for supplying a plating bath i/got into a plating bath.

[Prior art and its problems]

For example, in hot-dip galvanizing a steel strip, the steel strip is continuously guided into a plating tank containing a hot-dip galvanizing bath, and is turned upward in the entire direction of movement by a zinc roll installed in the plating tank. This is done by squeezing out excess plating solution with gas injected from a gas injection nozzle provided above the plating tank.

The hot-dip galvanizing bath in the plating tank decreases as plating progresses, so to replenish it, zinc implant (fx) must be supplied into the plating tank as needed.

Inputting an ingot into a plating tank like this is conventionally carried out by lifting the ingot, which is in the ingot electric field, using a hanging fixture attached to the tip of a crane's wire, transporting it above the plating tank, and then loading it into the plating tank. However, this was done by charging the pieces one by one into the plating tank using a charging machine installed near the plating tank.

However, this method is extremely inefficient as it involves introducing ingots one by one into the plating bath, and not only is it extremely inefficient but also... Since it will be thrown from the air at a considerably higher rate,
There may be problems such as splashes from the plating bath splashing around the plating tank and being dangerous. As a means to solve this problem, a known method is to install a hanger on the ingot and suspend the plating bath from scattering into the plating bath. However, there was a problem in that it required the production and collection of hanging handles.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a complete method for efficiently and safely feeding ingots for a plating bath into a plating bath.

[Summary of the invention]

This invention has hook-shaped joints at both ends, and a plurality of ingots connected to each other by the joints are placed close to one end of the plating tank and above the plating tank. The ingots are continuously transported into the plating tank by a feeding mechanism provided above one end of the plating tank and tilting downward into the plating tank. It is characterized by its supply.

. [Structure of the invention] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a side view of an ingot for use in a plating bath in the method of the present invention. As shown in the drawings, a hook-shaped joint 2 is formed at both ends of the ingot 10, and includes a groove 2a having a predetermined depth and a protrusion 2b having a lower height than the central portion.

Therefore, a plurality of ingots 1 are turned upside down and the protrusion 2 of the other ingot 1 is inserted into the groove 2a of one ingot 1.
By fitting b, a plurality of ingots 1 can be connected to each other by their cross sections 2.

As shown in FIG. 2 as a schematic plan view and as shown in FIG. 3 as a partial side view of the ingot supply, the ingot supply is located close to and above one end of the plating tank 3, and one end of which is located above the plating tank 3. A tiltable seat 1 as a mechanism is provided.

The chute 4 is tilted toward the inside of the plating tank 3 at a predetermined angle by a drive mechanism such as a hydraulic cylinder (not shown) about a horizontal shaft 5' (i-center). A belt conveyor 6 for continuously conveying ingots 1 to a position close to and above the plating tank 3, the end of the belt conveyor 6 being parallel to and close to the chute 4, and , and form the same plane as the chute 4.

One end of the belt conveyor 6 close to the chute 4 (C indicates that the pusher 7 for transferring, for example, three ingots 1 on the belt conveyor 6 onto the chute 4
It is placed towards the side of the 8 is a hydraulic cylinder for driving the pusher 7.

Ingot support rollers 9 for guiding and controlling the movement of the ingot 1 transferred onto the chute 4 are provided on the chute 4 so as to contact both sides of the ingot.

(a plurality of inbots connected to each other by a joint part 2)
1 is conveyed by a belt conveyor 6 to a position close to the chute 4. Next, by operating the pusher 7, for example, three ingots 1 are transferred onto the chute 4. Such movement of the ingots 1 onto the chute 4 may be performed one ingot at a time, and the number may be arbitrary.

The three ingots 1 thus transferred onto the chute 4 are moved to the ingot support roller 9 by fully operating the drive mechanism (not shown) to tilt the chute 4 as shown in FIG.
It is written that it is fed in and it slides into the plating tank 2.

Next, the chute 4 is completely returned to the horizontal position, and the above-described operations are repeated to supply ingots l into the plating tank 3 one after another.

FIG. 4 is a schematic side view showing another embodiment of the invention. In this embodiment, the belt conveyor 6 extends upward close to one side wall of the plating tank 3, and as the one side end tv of the plating tank 3 approaches, the belt conveyor 6 gently tilts downward into the plating tank 3. , the belt conveyor 6 itself forms an ingot supply mechanism. 10 is a fall prevention plate provided at the tip of the belt conveyor 6.

A plurality of ingots 1 connected to each other by joints 2 and moving on a belt conveyor 6 are sequentially supplied into a plating tank 3.

〔Effect of the invention〕

As described above, according to the present invention, ingots can be continuously supplied into the plating tank, and moreover, the ingots can be supplied from above close to the plating tank, and the hook-shaped joint can be used to melt the ingot. Since the parts are detached, splashes of the plating bath are not generated during feeding, and the ingot can be fed efficiently and safely, which is an excellent industrial effect.
