JPH067809A - High lubrication rolling mill - Google Patents

Abstract

(57) [Summary] [Purpose] The lubricant and coolant to be supplied to the rolls of the rolling mill are recovered respectively, and the separation device for them is not required. [Structure] A seal member is attached to the gap between the neck portion of the roll 2 and the chock, the gap between the chocks, and the gap between the roll necks to prevent the roll coolant 4 from flowing into the roll lubricant 5 and to perform lubrication. The agent 5 and the cooling agent are separated and separately collected in the pans 7 and 6 and reused.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-lubrication rolling mill capable of separating and recovering a roll coolant and a roll lubricant from each other.

[0002]

2. Description of the Related Art Generally, a lubricant is supplied to the interface between a roll and a rolled material by, for example, spraying a roll lubricant to reduce the friction between the roll and the rolled material and the load on the roll during rolling. In the rolling technology, the separation of the coolant and the lubricant after use is one of the technical problems.
In JP-A 7-206514, a technique of continuously sending a mixed liquid of a roll coolant, a lubricant and a sludge after rolling lubrication to a CPI oil / water separator to remove the sludge and separate and collect the coolant and the lubricant. Is disclosed.

[0003]

4 to 6 show a conventional method for supplying and recovering a roll lubricant and a roll coolant, and FIG. 4 is a perspective view showing one roll 2 and its chock 3. 5 is a front view of the upper and lower rolls 2 and 2, and FIG. 6 is the roll 2
FIG. For example, when the roll coolant flows to the end in the width direction while being pushed away by the roll drainer 11, the roll coolant 4 sandwiches the roll 2 from the gap between the neck portion of the roll 2 and the chock 3. It flows into the supply side of the roll lubricant 5 on the opposite side, is collected by the pan 8 in a state where the lubricant 5 and the coolant 4 are mixed, and is reused as it is.

According to the conventional general technique as described above, the roll coolant 4 after the rolling lubrication and the lubricant 5 are formed as shown in FIG.
From the viewpoint that it is unavoidable that they will be mixed with each other in the path as shown in, the mixed coolant 4 and lubricant 5 are
Trying to separate by some sort of separating device. For this reason, there are inevitably problems that the equipment cost for installing the separation device is high, the space for installation is insufficient, and that maintenance, inspection, and maintenance after the installation operation are troublesome and expensive.

[0005]

In order to solve the above problems, the present invention provides a seal member in the gap between the roll neck portion and the chock, the gap between the chocks, and the gap between the roll necks. , The roll coolant after use is prevented from flowing into the opposite side of the roll and mixing with the roll lubricant after use, and then the roll coolant and lubricant can be separated for recovery and reuse. Is.

The present invention comprises a mechanism for feeding a roll lubricant to the inlet side and a mechanism for feeding a roll coolant to the outlet side with a roll in the rolling direction, and a seal between the inlet and outlet sides. A rolling mill corresponding to high lubrication, which is provided with a mechanism and is provided with a recovery device for separating and recovering the roll coolant and the lubricant. The rolling mill according to claim 1, wherein the sealing portion is provided between the roll neck portion and the chock, between the chocks and between the roll necks.

[0007]

According to the present invention, in a rolling mill having a mechanism for supplying a roll lubricant to the inlet side and a mechanism for supplying a roll coolant to the outlet side with a roll in the rolling direction, a roll neck portion is provided. By installing a seal member in the gap with the chock, the gap between the roll chocks, and the gap between the roll necks, it is possible to prevent the coolant from mixing with the lubricant, and separate and collect the coolant and the lubricant. Since it can be reused, the installation cost of the separation device is unnecessary, and
The labor and cost of maintenance, inspection, and maintenance after installing the separation device are no longer required.

[0008]

1 to 3 show an embodiment of the present invention. 1 to 3 correspond to FIGS. 4 to 6, respectively, and the same reference numerals indicate the same parts. In order to solve the conventional problems, the seal member 1 is mounted in the gap between the neck portion of the roll 2 and the chock 3, the gap between the roll necks, and the seal member 9 is mounted in the gap between the chocks. 4 was prevented from flowing into the roll lubricant 5, and the lubricant 5 and the coolant 4 were separated and separately collected by the pans 7 and 6 so that they could be reused. In the above embodiment, the roll neck portion and the chock, roll neck comrades,
Although the example in which the seal member is attached to the gap between the chocks is shown, if it is not necessary to attach the seal member to all of the above due to the structure of the rolling mill or the like, the seal member may be only partially attached.

[0009]

According to the present invention, since the coolant and the lubricant can be separated, recovered and reused, the mixed liquid of the coolant and the lubricant can be reused as the coolant and the lubricant. Since it is not necessary to install a separation device for separation, the cost for installation, the trouble and cost of maintenance, inspection, and maintenance after the operation of installation is unnecessary.
