The present invention is a roll surface for the removal of various dust, scale, and other contaminants (hereinafter referred to as "surface foreign material") adhered to the roll surface in a facility using a roll, such as a rolling roll The present invention relates to a foreign material removal device, and more particularly, to a foreign material removal device for a roll surface of a skin pass line designed to easily and easily remove foreign materials adhering to a skin pass line roll surface of a steel mill.

The skin pass process is the final process of producing hot rolled products. Since the products that pass this process are finished products, the impact on the product quality is enormous. Therefore, the error in this process is an important process that causes a fatal defect in the quality, which is the life of the product. However, due to the nature of this process, hot coils often come to the skin pass process with the scale generated by the coolant injected for rapid cooling at high temperatures during the rolling process, especially on the surface of the coil. This scale causes the following problems.

First, the scale buried in the material is attached to and adhered to the surface of the skin pass roll, so that the surface of the product is stamped every time the roll is rotated, thereby creating a groove on the surface of the product.

Secondly, this buried scale is attached to the surface of the roll, which is characterized by its high hardness, which creates grooves in the surface of the roll to which the scale is attached during skin pads, leading to a situation where the roll cannot be used continuously. do. The grooved roll is inevitable to be regenerated by polishing the roll again. For this reason, the roll that is frequently polished causes the diameter of the roll to decrease gradually, resulting in a faster roll disposal time. Third, another problem is that the rolls are frequently changed due to the above problems, leading to a shortening of the operating time and a reduction in the production volume. Fourth, when the groove on the surface of the product occurs as described above, the coil is cut off and the defective position is cut out, thereby bringing a problem of lowering the error rate. It is necessary to keep the roll surface clean during the operation of the roll in order to prevent the scale, which is the biggest problem among the four, from being attached to the roll surface and rolling.

In the past, there was no proper device for this, so we have continued to work without removing scale or other foreign matter from the work roll of the skin pass line. There is a problem that the rate of product defects is high and the operation rate and productivity of the device are deteriorated due to frequent defects in the product due to stopping the line) and cleaning the roll surface by using a mop or other tool by hand. .

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a device capable of continuously removing foreign matters on the surface of a roll in a rolling pass skin pass line during operation of the roll.

In order to achieve the above object, the present invention provides a fixed table fixedly mounted to a support, a movable table inserted into the fixed table, which is installed in the fixed table and outgoing into or out of the fixed table by a hydraulic cylinder, and attached to the front of the movable table. The roll surface of the skin pass line, characterized in that it comprises a cleaning roller that is rotationally driven by a motor, provides a water removal device.

The hydraulic cylinder has a rear end connected to a bracket provided on the fixed table, and the front end connected to a stone piece provided on the movable table.

Guide wheels are provided on left and right sides of the movable table, and a motor for rotating and driving the cleaning roller is provided on one side of the upper surface.

The cleaning roller is mounted to a fixed table fixed to the front of the movable table by a roller shaft, and driven by a chain connected between a drive sprocket of the shaft end of the motor and a driven sprocket of the roller shaft end. .

Hereinafter, the configuration and operation of the present invention will be described in more detail based on the accompanying drawings.

1 is an exploded perspective view of a roll surface foreign matter removing device according to the present invention, Figure 2 is a perspective view of the state of use of the apparatus.

The device according to the present invention comprises a fixed table (1) fixedly mounted to a support (6), which is inserted into the movable table (2) with guide wheels (5) on both sides so that it can be projected. In order to form and install the hollow part 1 'which is installed, the bracket 3 for connecting and fixing the rear end part of the hydraulic cylinder 7 with the fixing pin 4 is provided in the upper part.

The movable table 2 is equipped with a plurality of guide wheels 5 inserted into the hollow part 1 'of the fixed table 1 at both left and right sides thereof and sliding along both sides of the hollow part 1. The upper front is provided with a motor (9) for rotationally driving the stone piece 25 and the cleaning roller 19 for connecting and fixing the front end connecting portion (8) of the hydraulic cylinder (7), the cleaning roller ( The fixing plate 13 supporting the installation of the roller shaft 15 by 19 is coupled to the fixing bolts 12.

A hydraulic cylinder 7 is mounted between the bracket 3 on the stationary table 1 and the protrusion piece 25 on the movable table 2 to move the movable table 2 to the hollow portion 1 of the stationary table 1. ') Operates in and out of the house.

A roller shaft 15 having a key 14 is inserted through the center of the cleaning roller 19, and both ends of the roller shaft 15 are interposed between the stopper 16 and the bearing block 17. Both ends of the fixed plate 13 are mounted and supported by a rotating material.

A drive sprocket 10 and a driven sprocket 18 are respectively installed at the end of the motor shaft 11 and the one end of the roller shaft 15 of the motor 9, and the drive sprocket 10 and the driven sprocket 18 are respectively provided. Between the chain 20 is installed.

In this operation of the present invention, since the contact position of the cleaning roller 19 is changed according to the diameter difference of the workpiece roll to remove the foreign matter, the hydraulic roller 7 is operated to adjust the position of the cleaning roller 19 to adjust the work roll. The motor 9 as a power source for the relative sliding movement of the work roller and the cleaning roller 19, and then the driving sprocket 10 and the roller shaft 15 end of the motor shaft 11 end. The roller shaft 15 is rotated by the chain 20 connected between the driven sprockets 18 of the rollers, and thus the cleaning roller 19 is rotated to remove and remove the surface of the work roll.

At this time, the bearing block 17 and the stopper 16 are both ends of the roller shaft 15 in order to prevent the smooth rotation of the roller shaft 15 and the left and right flow due to the trust force of the cleaning roller 19. The cleaning roller 19, its roller shaft 15, and its accessories can be disassembled into one set on a fixed plate 13 for replacement of the cleaning roller 19 when it is worn or damaged. The fixed table 13 is fixed to the movable table 2 by the fixing bolts 12 so that the cleaning roller 19 can be immediately replaced when necessary. At the time of replacing the cleaning roller 19, the whole cleaning roller set including the cleaning roller 19, the roller shaft 15, and the fixed plate 13 is replaced with a new one, and the cleaning roller of the replaced cleaning roller set is replaced. Replace (19) with the roller shaft (15) and install the whole set with a new one. Then, put the cleaning roller (19) of the replaced cleaning roller set onto the roller shaft (15), and then replace the cleaning roller set. Get ready.

The present invention has been described as having a very inefficient problem in terms of safety protection, facility operation rate, productivity and aspects by stopping the operation of the skin pass line and removing the foreign body of the worker's work surface. The surface of the work roll can be easily and safely removed mechanically while the line continues to operate, which is a useful design that can improve the product quality, extend the life of the work roll, and improve the work stability and productivity.
