Description

[0001] APPARATUS FOR COOLING [0002]

The present invention relates to a coolant-regulated cooling device.

 Generally, the coated steel sheet is excellent in corrosion resistance and spot weldability, and therefore, there is an increasing demand for steel sheets for building materials, electronic products, and automobiles.

Describing the process of manufacturing a galvanized steel sheet, which is one of such coated steel sheets, a steel sheet unwound from a payoff reel is heat treated through a welder and a looper.

Then, the steel sheet passes through a sink roll, a stabilizing roll or guide rolls through a Snart and a plating bath, where molten zinc is attached to the surface of the steel sheet. In the upper part of the plating bath, a gas wiping facility called an air knife is installed. By spraying high-pressure gas (inert gas or air) from the gas wiping facility, the thickness of the steel plate is controlled.

At this time, in order to prevent the zinc plated layer from peeling off from the steel sheet, the zinc plated layer must be hardened, but the hardening of the zinc plated layer can be realized by cooling.

That is, a certain cooling device is installed in the conveyance path of the steel sheet to supply a certain amount of coolant to coagulate the zinc plated layer adhered to the surface of the hot plated steel sheet, and the temperature of the steel sheet is lowered, .

If the supply amount and the supply distance of the coolant are not properly controlled during the cooling process, there is a problem that the zinc plated layer has abnormal patterns or wrinkles. In the case where the zinc plated layer is not completely dried, There is a problem that a mark defect or the like may occur.

When the second coolant is discharged through the discharge passage of the nozzle cover, part of the first coolant is also discharged to the outside of the first discharge port 124 by the pressure by the supply pump (not shown) and the pressure by the second coolant And can be discharged and supplied to the object 1.

Therefore, in consideration of the width of the object 1, it is possible to provide a plurality of first outlets in accordance with the width of the object 1, and to insert the nozzle covers into the first outlets, . ≪ / RTI >

At this time, since the supply amount of the first coolant is determined according to the depth of the nozzle cover inserted into the first outlet, when the thickness of the object 1 exceeds 1 mm, the nozzle cover is inserted only slightly into the first outlet, The amount of the first coolant supplied to the object 1 can be increased.

In this way, the supply amount of the first coolant may be adjusted by controlling the moving distance of the moving plate 221 to adjust the depth of insertion of the nozzle cover into the first outlet. 3, when the rod 222b of the driving cylinder 222 is extended to move the moving plate 221 to the maximum position and the nozzle cover 221d is completely inserted into the first outlet 124, The supply amount of the coolant can be minimized.

In addition, when the outer diameter of the nozzle cover 221d and the inner diameter of the first discharge port 124 have interference fit tolerances, when the nozzle cover 221d is completely inserted into the first discharge port 124, May be interrupted.
