The present invention relates to a surface treatment device for a metal plate for a cladding plate that is cleaned and activated.

[Prior Art] When manufacturing a clad plate by cold rolling, for example, the joint surfaces of a plurality of metal plates constituting the clad plate are treated in advance to remove rust, oil, etc. from the joint surfaces. It is necessary to completely remove the deposits. At the same time, it is necessary to make the bonding surface of the metal plate a fresh surface with a large surface area to facilitate diffusion of pressurized metal atoms and bonding during rolling.

Conventionally, the surface treatment for the joint surfaces of such metal plates was
Using a so-called unitized polishing means, such as a brush roll that rotates in contact with the joint surface,
This was done by pressing the polishing means against the joint surfaces of the metal plates.

[Problems to be Solved by the Invention] However, surface treatment using a unitized polishing means such as a brush roll may cause the polishing of the joint surface of the metal plate due to changes over time of the plan roll etc. It happens that the level of cleaning changes. Therefore, it was difficult to maintain a stable level of cleaning, and it was also necessary to periodically stop the clad plate production line and replace plan rolls and the like.

This invention solves these conventional problems.

Means for Solving Problem L] The surface treatment apparatus for a metal plate for a cladding plate according to the present invention has the following features:
In order to solve the above-mentioned conventional problems, a clad plate is installed at the entry side of a rolling roll that joins multiple metal plates to form a clad plate, or in an upstream process, and grinds the joint surface of each metal plate. In a surface treatment device for metal plates, a guide is used to guide a plurality of metal plates between rolling rolls with their joint surfaces facing each other, and a guide located between the facing joint surfaces of the marked metal plates to guide them between rolling rolls with their joint surfaces facing each other. It is characterized by comprising a nozzle that sprays the abrasive material toward the joint surface, and a cleaning means that is located on the rear side of the nozzle in the direction of movement of the metal plate and that cleans the abrasive material from the surface of the metal plate. It is said that

The payoff reels R, , R, are arranged side by side in the horizontal direction, and the metal plates W, , W, from these payoff reels R, , R2 are rolled after passing through the inside of this surface treatment apparatus. Enter between rolls 1 and 2.

The surface treatment apparatus has a casing 3 that surrounds the metal plates W + and W t over a predetermined range, and a guide roll 4 is provided for the casing 3 . The guide roll 4 includes a metal plate W located inside the casing 3,
, W, so that they face each other at a predetermined interval.
It serves as a guide for these metal plates W + and W t. By this guide roll 4, the metal plates W, , W,
The joint surfaces of the two are opposed to each other with a predetermined interval. In this example, this guide roll 4 is
The pass line rollers are located at the front side A6 and the rear side of the roller.

A plurality of nozzles 5 are provided within the casing 3 and located between the metal plates W, , W,. This nozzle 5 is connected to a granular abrasive supply device (not shown) through a supply line L, and simultaneously sprays the abrasive material from the supply device toward the joint surfaces of the metal plates W + and W t. It is something. The abrasive material is, for example, iron sand, iron ball, or sand.

In this example, the direction in which the abrasive material is sprayed is in a direction (to the right) opposite to the moving direction (to the left) of the metal plates W + and W t, as shown in Fig. 2. .

A wiper (cleaning means) 6 is provided on the rear side of the casing 3, that is, on the left side in FIG. This wiper 6 is for cleaning the abrasive material from the surfaces of the metal plates W + and W t, and in this example, the wiper 6 is

It is constituted by a wiper brush 6b that is in contact with the surface of W2. Moreover, the metal plates W, , W in the casing 3
A sealing mechanism for sealing the inside of the casing 3 is provided at the inlet and outlet portions of t. Further, a lower part of the casing 3 is provided with a lower part for taking in the abrasive material after it has been sprayed onto the metal plates W, Wt, and this lower part of the taking part is connected to an abrasive material collection device 8. . This recovery device 8 removes foreign matter from the abrasive material taken in from inside the casing 3, and removes abrasive material that cannot be reused.
The abrasive material is then returned to the abrasive supply device for reuse.

Next, the effect will be explained.

The surface treatment device has a metal plate W1 inside its casing 3. Spray the abrasive toward the joint surface of W t. This sprayed abrasive material is applied to the metal plate W1. W
At the same time, the joint surfaces of the joints are polished and deposits on the joint surfaces are continuously removed and activated. And metal plates W,,W
After cleaning the joint surface of the metal plate W, the abrasive material falls sequentially from both sides of the metal plate W while containing deposits due to the action of the wiper 6, as shown in FIG. 3, and is collected from the intake lower. is guided to device 8. In this recovery device 8, deposits and the like in the abrasive material are removed, and the abrasive material is returned to the abrasive material supply device again. Therefore, an abrasive circulation system is formed between the present surface treatment device and the recovery device 8.

The metal plates W, , W, whose bonding surfaces have been ground in this way and the abrasive material has been removed from the surfaces are rolled into rolling rolls 1.2
They are joined together to form a clad plate. At this time, since the bonding surfaces of the metal plates W I and W t are activated, they are strongly bonded.

Incidentally, among the plurality of nozzles 5 arranged along the moving direction of the metal plates W + , W t , a large-sized abrasive material is sprayed from the nozzle 5 located on the front side in the moving direction of the metal plates W + , W t . The abrasive material having a small particle size may be sprayed from the rear side of the plates W + and W t in the direction of movement. In this case, in the casing 3, the metal plate W
