Description

DETAILED DESCRIPTION OF THE INVENTION The present invention #J relates to a cleaning device for a rolling mill, and particularly to an automatic cleaning device suitable for use in a temper rolling mill that produces jIk finished products.

In general, high-quality products manufactured by cold rolling and tempering rolling mills or skin pass tempering mills that perform dry skin pass, etc.
In the case of 8E rolling, if a single drop of water, oil, or - adheres to the roll or strip product during rolling, the product will be defective. For this purpose, I take out all the rolls, wash them with roll syrup, wipe them with a cloth, and then put them back together. Furthermore, the rolling mill itself is large and difficult to clean, so several workers go inside the mill and clean it using hoses with nozzles and brushes. However, a large amount of rolling oil residue and iron powder adheres to all parts and equipment, so it takes a lot of time to wash them off.Furthermore, as for oil and fat, hot water is sprayed on all parts at the same time to wash them. The mill had to be dried in the air, and at the end it had to be partially wiped by hand in addition to a confirmation inspection.As a result, there was a problem in that the mill operation rate decreased and a large number of workers were required. Moreover, in addition to requiring a large amount of time and a large number of workers, there are also six problems in terms of hygiene and safety, as the work involves spraying away oil stains, iron powder, etc.

An object of the present invention is to carry a cleaning cart into a housing using rails when cleaning a rolling mill.
An object of the present invention is to provide a rolling mill cleaning device for automatically cleaning a rolling mill.

In order to keep a rolling mill clean, reducing the number of internal parts will reduce the number of places dirt can stick to and make it easier to clean. For this reason, it is undesirable to install the cleaning device fixedly inside the device because it increases the amount of deposits. Therefore, it is necessary to carry the outer cleaning device into the housing. Items that require thorough cleaning are large devices, and the method of transporting them becomes an important issue, but by transporting the washing cart into the housing using rails, this can easily be done economically.

Hereinafter, one embodiment 91 of the present invention will be described with reference to the drawings.

FIG. 1 shows the assembly of work rolls and reinforcing rolls C (not shown) inside the housing 1.2 taken out for reassembly. The housings 1.2 are connected at their upper sides by an upper separator 3, and their lower sides W are each fixed to a sole plate 4.

Operate from this drive side housing 1.
Two roll recombination rails 5 are arranged so as to pass through the inside and extend toward the operation side, and a cylinder 15 for roll recombination is arranged between these two roll recombination rails 50. has been done. After the rolls have been extracted and carried away by the roll shop, a washing cart 6 carried in by a crane is placed on the roll recombination rail 5 on the operating side. At the lower part of the operating side of the washing cart 6, there is a joint portion 2 connected to the cylinder 15.
1 are provided and are connected via a bottle or the like.

In addition, the washing cart 6 is equipped with a high-pressure water injection header 10 and a plastic fitting! Various cleaning devices such as a dry air jetting device 12, a hot water jetting header 22, etc. are installed, and furthermore, at the front and rear of the cleaning cart 6, there are support plates 13, 14 having the same shape as the window portion of the housing 1.2. is provided to prevent the cleaning liquid from scattering to the outside during the cleaning operation. On the outside of the closing plate 13 on the operating side of the washing cart 6, an operation control panel 7 for operating various washing devices is provided. In addition, for operation, a connection board 8 for a power supply, various cleaning liquids, and pressure sources is arranged at the bottom of the washing cart 6.
At the location where the cleaning fluid is inserted into the housing 1.2, power and various cleaning fluids are connected and supplied from a source fixed nearby by means of cables and flexible tubes.

Further, seven hooks 9 are provided on the upper side closing plates 13, 14 of the washing cart 6 so that the washing cart 6 itself can be quickly and easily transported on clay.

In the washing cart 61 made in this way, one housing is 1°2.
Figure 2 shows the inserted state. In this state, each outer surface of the housing 1.2 is flush with the closing plate 13.14, and the dirt and cleaning liquid inside will not be scattered to the outside.
The interior of the window will be thoroughly cleaned of salt. FIG. 3 shows a front view of the housing into which the washing cart 6 is inserted. As shown in FIG. 3, the washing cart 6 is inserted and the window of 1/2 is covered by the closing plate 13.
In the pass direction of the rolling mill, a guide frame 20 containing a header 19't for roll coolant and rolling lubricant is arranged between the posts of the housing 1.2, and these also need to be thoroughly cleaned.

Since the injection jet arrives at this mm, it is effective to also close the outer frame of the housing 1.2.For this purpose, the shutter box 16 is
are provided at the front and rear, which allows the shutter 17' to be closed during washing.
ft. to prevent scattering. In this way, the washing cart 6 is inserted into the housing 1.2 and further closed by the bus-direction shutter 17 to effectively wash the inside of the mill.

Due to space considerations, it is impossible to permanently install various types of washing devices such as those mounted on the washing cart 6 in one housing 1.2. It is therefore necessary to introduce it into the interior of the housing 1.2 without rolls. but,
In the path direction, there is a guide frame 20 as described above,
Furthermore, there is a spindle 23 for driving rolls on the drive side, so it cannot be carried in. On the other hand, since the upper separator 3 is provided on the upper side, it is not possible to carry it in by clay. Therefore, the only method is to carry it in through the window on the operation side, but according to this operation method, 5 tons of roll changing rails are used, a hydraulic cylinder is installed in a truck system, and 9 motors are attached to the truck. There is a need for a way to transport the vehicle as a self-propelled vehicle. As described above, the present invention allows automatic cleaning of a rolling mill to be carried out effectively and by a single operator without being restricted by conventional mechanical equipment, and moreover, it is possible to automatically clean a rolling mill by carrying a cleaning cart into a housing. This is something that can be easily done by making use of the rail for recombining rolls.

As described in detail above, according to the present invention, various devices for cleaning a rolling mill are mounted on a cleaning cart, carried into the window of the housing using rails, and the cleaning operation is performed and the operation is completed. After that, during the extraction and rolling operations, the washing cart was not placed deep inside the mill. In this way, I-
The washing trolley can be stored in a convenient space, so various washing devices can be installed, and washing can be carried out effectively.

In addition, since the washing cart is not inside the mill during rolling, there is less dirt and deposits1, resulting in better rolling.
Furthermore, the front and rear closing plates of the washing cart can be made to have the same shape as the washing window, which is very effective in preventing scattering. In addition, in the case of several mills such as tandem mills,
Place the washing cart on the rail with a crane! Since it can be used multiple times, one washing cart is sufficient. Furthermore, since the washing operation can be remotely controlled by a single-proboscis operator, it is safe and sanitary. In addition, if you use the rail for recombining rolls as the rail for the washing trolley, you can use special loading equipment!
It is economical as it does not require t.
