Cooling System

Abstract

A cooling system according to an embodiment of the present invention may comprise: a cooling part which supplies a cooling fluid to a strip; and a boiling film removal part, which physically comes into contact with the strip and removes a boiling film formed by the cooling fluid. The boiling film removal part according to the embodiment may be disposed at a position where a nuclear boiling and a film boiling are mixed together along a widthwise direction of the strip.

1 . A cooling system comprising:
 a cooling part which supplies a cooling fluid to a strip; and   a boiling film removal part which physically comes into contact with the strip and removes a boiling film formed by the cooling fluid.   
     
     
         2 . The cooling system of  claim 1 , wherein the boiling film removal part has a shape of a roller. 
     
     
         3 . The cooling system of  claim 2 , wherein the boiling film removal part includes a brush, disposed on an external circumferential surface of the roller, and the brush is partially brought into contact with the strip to remove the boiling film. 
     
     
         4 . The cooling system of  claim 1 , wherein the boiling film removal part is disposed in a position where a nuclear boiling and a film boiling are mixed together along a widthwise direction of the strip. 
     
     
         5 . The cooling system of  claim 3 , wherein the brush of the boiling film removal part is formed of an acrylic material. 
     
     
         6 . The cooling system of  claim 1 , wherein the cooling part includes a flow control cooling device disposed on a back end of the boiling film removal part and configured to control a flow rate based on a temperature deviation in the widthwise direction of the strip. 
     
     
         7 . The cooling system of  claim 6 , further comprising:
 a temperature measurement part disposed on at least one of a front end and a back end of the cooling part to measure a temperature of the strip; and   a control part configured to control the flow control cooling device based on the temperature measured by the temperature measurement part.   
     
     
         8 . The cooling system of  claim 6 , further comprising:
 a flatness measurement part disposed on at least one of a front end and a back end of the cooling part to apply tension to the strip and to measure flatness of the strip; and   a control part configured to control the flow control cooling device based on the flatness measured by the flatness measurement part.   
     
     
         9 . The cooling system of  claim 1 , wherein the cooling part includes a cooling tank in which a cooling fluid is contained, and
 the boiling film removal part is disposed inside of the cooling fluid.   
     
     
         10 . The cooling system of  claim 9 , wherein the boiling film removal part is disposed in a location adjacent to a liquid surface of the cooling fluid in the cooling fluid. 
     
     
         11 . A cooling system comprising:
 a measurement part measuring a temperature deviation in a widthwise direction of a strip and flatness of the strip; and   a flow control cooling device controlling a flow rate based on the temperature deviation or the flatness, measured by the measurement part, and injecting a cooling fluid to the strip.   
     
     
         12 . The cooling system of  claim 11 , wherein the measurement part is disposed on both a front end and a back end of the flow control cooling device.
