Definitions
- the measuring unit may be disposed at the front and rear ends of the flow rate control cooling apparatus, respectively.
- FIG. 3 is a schematic view of the flow control cooling device shown in FIG. 2; FIG.
- the temperature measuring unit 30 measures the temperature of the strip S at both the start point and the end point of the cooling section.
- the present invention is not limited thereto and may be disposed only at the rear end of the cooling unit 20 as necessary.
- the controller 70 continuously compares the state of the strip S entering the cooling section with the state of the strip S discharged from the cooling section, and corresponds to various states of the strip S at the time of entry. Can be used to derive the optimum flow rate injection conditions.
- the outer surface of the boiling film removing unit 50 is not limited to the shape of the brush 52.
- the outer circumferential surface may be formed in the form of a foam, or may be formed in various forms as long as the material can contact the strip S to shake off the boiling film on the strip S, such as forming a plurality of layers of the net on the roller. Can be.
- the cooling rate of the strip S differs when the membrane boiling point B1 and the nuclear boiling point B2 are mixed. Will occur. Therefore, a temperature deviation occurs in the cooling process, which affects the flatness of the strip (S).
- the cooling device includes a boiling film removing unit 50.
- the boiling film removing unit 50 removes the boiling film of the portion where the film boiling (B1) and the nuclear boiling (B2) are mixed. Accordingly, the boiling film (B1) and the nuclear boiling (B2) are removed. The occurrence of temperature deviation in the width direction can be minimized.
- the cooling effect can be maximized, and the temperature variation in the width direction of the strip S can be effectively reduced.
- the cooling system 10 is a system for cooling by moving the strip S vertically, and the strip S inside the cooling tank 25 containing the cooling fluid 26. ) Is arranged to pass.
- the cooling unit 20 includes a cooling tank 25 in which a cooling fluid 26 is accommodated.
- the strip S is vertically moved and is introduced into the cooling tank 25 and moved out of the cooling tank 25 after a predetermined distance. Therefore, the cooling tank 25 is provided with a plurality of guide rolls 27 for supporting and guiding the strips S for smooth movement of the strips S.
- the boiling film removing unit 50 removes the boiling film of the portion where the film boiling and the nuclear boiling are mixed, and thus the temperature deviation in the width direction of the strip S due to the film boiling and the nuclear boiling. Can be minimized.
