摘要： PURPOSE: To heat-treat many kinds of steel sheet suitably to characteristics thereof, by combining suitably coolings by gas jet, roll and water in a strip cooling apparatus of the continuous annealing line.
CONSTITUTION: A strip 0 is introduced to the first cooling zone 2 from a soaking zone 1, and can be cooled by blowing gas by a gas jet cooling means 21. Thereat, cooling quantity of the strip can be controlled by adjusting quantity of gas blowing. Next, the strip 0 is introduced to the second cooling zone 3 and cooled by winding it to the roll cooling the inner part of a roll cooling means 31. Winding angle of the strip can be regulated by moving the roll 31 in an arrow 35 direction. Next, the strip 0 is entered to the third cooling zone 4, can be held thermally or cooled slowly by a gas jet cooling means 41, then can be roll cooled by means 51 at the fourth cooling zone 5. At last, the strip 0 is entered to the fifth cooling zone 6, and can be cooled by dipping it in a water cooling vessel 61.

摘要： The invention relates to apparatus of the kind in which the strip (2) is passed in contact partly around the outer circumferences of a number of spaced cooling rolls (1, 1 min etc.) through which collant passes. … In conventional apparatus of this kind numerous problems arise with respect to the limited range of temperature that can be applied, due to the coolant used, and the fact that irregularities can occur widthwise of the strip. … The invention aims to overcome these problems and is characterized in that temperature detection means (17, 17 min etc.) are provided for detecting the temperature of the strip (2) before contact with each said cooling roll (1, 1 min etc.), in that coolant temperature adjusting means (16) are provided which, in dependence upon the detected temperature (Ts1), are adapted to adjust the temperature of the coolant passing through each cooling roll to a range (Tw1) which limits the temperature drop (Tsm) such that unacceptable irregularities or distortions in the configuration of the strip cannot occur, and in that the coolant used for each cooling roll is selected with a boiling point appropriate to the respective detected temperature for each roll. … In a preferred arrangement, further temperature detection means (18) are provided for each cooling roll to detect the temperature of the coolant and output signals (Ts and Tw respectively) from both detection means (17, 18) are inputted to a control (19) for regulating a flow rate valve (16).

摘要： COOLING APPARATUS FOR METAL STRIP The invention relates to apparatus of the kind in which the strip (2) is passed in contact partly around the outer circumferences of a number of spaced cooling rolls (1,1' etc) through which coolant passes. In conventional apparatus of this kind numerous problems arise with respect to the limited range of temperature that can be applied, due to the coolant used, and the fact that irregularities can occur widthwise of the strip. The invention aims to overcome these problems and is characterized in that temperature detection means (17,17' etc) are provided for detecting the temperature of the strip (2) before contact with each said cooling roll (1,1' etc), in that coolant temperature adjusting means (16) are provided which, in dependence upon the detected temperature (Ts1), are adapted to adjust the temperature of the coolant passing through each cooling roll to a range (Tw1) which limits the temperature drop (Tsm) such that unacceptable irregularities or distortions in the configuration of the strip cannot occur, and in that the coolant used for each cooling roll is selected with a boiling point appropriate to the respective detected temperature for each roll. In a preferred arrangement, further temperature detection means (18) are provided for each cooling roll to detect the temperature of the coolant and output signals (Ts and Tw respectively) from both detection means (17,18) are inputted to a control (19) for regulating a flow rate valve (16).

摘要： PURPOSE:To enable the cooling of a strip without generating a shape defect and material defect by detecting the temp. distribution in the transverse direction of the strip on the outlet side of a cooling roll group and controlling the suction pressure of cooling rolls in accordance with the temp. difference thereof. CONSTITUTION:The temp. distribution in the transverse direction of the metallic strip 1 is detected by a temp. profile gage 6 provided on the outlet side of the adsorption type cooling roll group 2. A control operator 8 calculates the temp. difference in the transverse direction of the metallic strip 1 by this signal and decides the need for suction of respective blowers 3 in accordance with the equation I. A suction pressure (p) and the rotating speeds of the blowers 3 to obtain the suction pressure (p) are calculated by the equation II (h is a sheet thickness mm) and are transmitted to a motor controller 4 when the suction is needed. Furthermore, feedback control is executed in accordance with the signal from a pressure gage 5 to control the suction pressure of the cooling rolls 2 to the prescribed pressure.
