Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a line transfer device for removing water droplets and the like that adhere to the edges in the width direction of a trip rolled by a rolling machine.

□In conventional rolling mills, there is a water drain 'W' on the discharge side.
It is known that there is a problem with the structure in which the ice is cut off by the air pressure that is ejected from the ice cubes installed at fixed positions. 1 JP 1853-364
'26, the coolant liquid flows out from the gap formed between the opposing joints of the 1lE-machine □1L No. 11-. A draining device with a pacer on the left side is ready. According to this method, the amount of movement east that removes the coolant liquid and water droplets on the surface of the strip is small, but the thickness direction of the strip, that is, the ridge of the soil volume, is d] relative to trifle] Since the position in the force direction was fixed, an appropriate spray angle corresponding to the 13 changes in the strip could not be obtained and a perfect wiping effect could not be obtained. Japanese Patent Application Laid-Open No. 77258/1983 proposed a method with 75 air nozzles and contact brushes, but according to this method, the air consumption was 4 Moreover, the contact brush was still severely worn, and the IJ knob was easily damaged, which significantly reduced the quality of the product. In particular, the conventional wiping method described above has many problems during high-speed rolling.

The present invention was made in view of the facts in Article 4.
11 Attached to the edge of the tube 1- Easily and reliably removes water droplets, etc., thereby preventing the occurrence of rust and making it possible to obtain a high quality strip coil.
A strip edge wiper device for a rolling mill is provided.

The present invention provides a strip edge wiper device for removing coolant liquid and water droplets adhering to the edges of a strip rolled by an FE rolling mill. By installing an air header that can be moved from side to side at the bottom of the strip, and obtaining an appropriate air jet angle, water droplets etc. adhering to the strip edges can be easily and reliably removed. In addition, a soundproof board was placed around the air helicopter to prevent noise.7 In order to detect the position of the air helicopter, a detection device using mechanical indicators and monitor television was installed. This is a characteristic feature.

1. With reference to the drawings, an embodiment of a strip edge wiper device for a rolling mill according to the present invention will be described below. I will explain.

FIG. 1 is a plan view showing the arrangement of a strip edge wiper device, FIG. 2 is a partially sectional front view thereof, and FIG. 3 is a partially sectional side view thereof. The strip is rolled by means of work rolls 3, 4 which are fitted in the roll housings 1, 1' and the project block 2.2'. A 1-le coolant header (not shown) is provided on the roll entry side to supply coolant oil to the strip.

Air headers 7.7' are installed above and below on the roll exit side, and the minimum width (actual #) of the rolled strip is 5.
It is possible to move left and right so that air can be injected at an appropriate injection angle to the edge portion from 6 to the maximum board width (dotted line). An air manifold 8 and guide rods 9, 9' for operating the header are attached to the air header 7, 7', and a hydraulic actuator 10
The air header 7.7' can be moved to any desired position using the drive source 10'. Still, a hanging fitting 11 is fixedly installed on the air hem A-7/7, an air wire 12 is fixed on the hanging fitting 11, and is fixed via a pulley 13 in an easily operable place on the roll housing 1°1'. A weight/pointer is fixed to one end of the aircraft wire 12 so that the position of the air header 7.7' can be visually confirmed mechanically. Further examples and 1. By combining the aeronautical wire 12 with a sprocket and a chain and introducing a signal to the Sershin oscillator, the position of the aerodynamic machine can be electrically displayed and controlled. ), it is also possible to detect the position of the air header 7.7'. Soundproof plates 16, 1.6' are fixed to the side walls of the air header 7.7'. 17 is the guide rod 9 which also serves as a soundproof plate.
9' is a protective cover, and 18 is an air source piping hose.

As shown in Fig. 3, on the exit side of the rolling mill, roll change rails 14, pass line rollers 157z, etc. may be arranged, and the space for incorporating the wiper device is very small, so the wiper device is It is of a compact type and is placed extremely close to the work rolls 3.4.

According to the strip edge wiper device of the present invention configured as described above, the air header can be disposed at the most appropriate position with respect to the strip edge, and the air header can be placed close to the work rolls 3 and 4 and can be sprayed at an appropriate position. Since air can be ejected depending on the angle, water droplets etc. adhering to the IJ edge can be most effectively removed. !
! The effect of the soundproof walls 16°16' installed on the side walls of the upper and lower air headers 7.7' can significantly reduce noise1, and the air consumption is still lower than that of conventional wiper devices with multiple air nozzles. The amount can also be significantly reduced.

As described in detail above, the present invention relates to a strip edge wiper device for removing coolant liquid and water droplets attached to the edge portion of a strip rolled by a rolling mill. Since the header is arranged and the air header is movable in the width direction of the board, an appropriate air injection angle can be obtained.
Coolant liquid and water droplets attached to the strip edge can be reliably and easily removed, air consumption can be significantly reduced compared to a wiper device with multiple air nozzles, and noise can also be significantly reduced due to the effect of the soundproof wall. It has great effects, such as the ability to save money.
