Description

Height variable rolling oil float removal device {APPARATUS FOR REMOVING SUSPENSION MATTERS ON ROLLING OIL}

The present invention relates to a device for removing suspended matter (SUSPENSION MATTER) is installed on the top of the rolling oil tank for storing and circulating the rolling oil used in the cold rolling line, more specifically, the fixed float remover tank The present invention relates to a height-variable rolling oil floatation removing device capable of more completely removing suspended solids suspended in a rolling oil by providing a variable type in which the height is variably adjusted according to the rolling oil level (LEVEL) in the interior.

In general, the cold rolling line is used to reduce the friction during the rolling of the strip and to use the rolling oil for oiling, rust prevention, cooling and lubrication of the strip. Such rolling oil is used in a circulating manner in a state in which the rolling oil is stored in the rolling tank. On the rolling oil level of, foreign matters, for example, suspended matter such as SCUM, which is an impurity such as iron contained in the rolling oil, is suspended.

At this time, the scum is a floating material mixed with foreign substances such as fine iron powder generated during rolling due to deterioration of the rolling oil, such floating material is included in the recycled rolling oil and used on the surface of the steel sheet being rolled while being attached to the roll of the rolling mill It causes roll mark (MARK), which causes the defect of the product, and thus, rolling oil is circulated in a circulating manner while continuously removing the floating matters in the rolling tank as described above.

On the other hand, Figure 1 shows a magnetic filter for removing impurities such as scum installed in the rolling oil tank used in such a cold rolling line.

That is, as shown in Figure 1, the magnetic filter 130 is installed in the inside of the rolling oil 120 is filled in the tank 110, such magnetic filter 130 is mainly composed of iron components included in the rolling oil scum Clean water and rolled oil are mixed in the tank 110 while adsorbing and removing them by magnetic force to keep the concentration in the tank constant.

However, in the removal of impurities using the conventional magnetic filter 130 as described above, only iron components of a predetermined particle or more can be removed so that fine iron powder or the like is suspended on the rolling oil 120 in the tank 110. Since it is reused as it is, it was impossible to completely remove product defects such as roll marks of steel sheets.

Therefore, another conventional rolling oil float removal apparatus for solving the above conventional problems is shown in Figure 1b.

That is, as shown in Figure 2, by installing the suspended matter remover 200 is orbitally transported on the rolling oil level inside the tank 110 to discharge the suspended matter such as fine iron powder suspended in the rolling oil tank 110 ( 110 ') to remove externally.

However, in the other conventional rolled oil floater remover 200 as described above, even if the level of the rolled oil is variably changed without maintaining the level of the rolled oil 120 in the tank 110 at all times, the upper portion of the rolled oil 120 The installed float remover 200 is fixedly installed, so that when the level of the rolling oil is variable, there is a problem that it is difficult to efficiently remove the float.

As a result, in the case of the conventional magnetic filter 100 or the float remover 200, suspended matter such as scum, which is an iron component contained in the rolling oil 120, cannot be completely removed. There is a problem that provides the same steel sheet failure factors.

The present invention has been made in order to improve the various problems as described above, the object of the present invention is to provide a device for removing suspended matter such as fine iron powder suspended in the rolling oil in the rolling oil tank is stored in the rolling oil used in the cold rolling mill It is to provide a height-variable type rolling oil float removal device to effectively remove the suspended matter suspended in the rolling oil by installing a variable type of the height is adjusted according to the level of the rolling oil.

In addition, another object of the present invention, by effectively removing the suspended matter such as fine iron powder suspended in the rolling oil, the steel sheet defect of the roll mark due to the fine iron contained in the rolling oil, etc. in the rolling operation of the steel sheet through the reuse of the rolling oil It is to provide a height-variable rolling oil floating removal device to improve the product quality of the steel sheet to prevent the in advance.
