Filed: 1988-01-20
Abstract: PURPOSE:To promote absorption of a coolant vapor to the absorption solution and further to prevent the absorption solution from staying within the absorption type freezer by adding specific saturated hydrocarbon of alcohol type to the absorption solution which consists of an aqueous solution mainly composed of alkali halide. CONSTITUTION:Saturated hydrocarbon of alcohol type to be added to an absorption solution has a boiling point in the range of 155-180 deg.C, and is for example, 2-ethyl-1- hexanol, 2-octanol, 1-heptanol, 2-methyl-1-hexanol, 1-hexanol, or the like. The amount of the saturated hydrocarbon to be added is set to 0.001-0.5wt.% with respect to the absorption solution. The absorption solution is placed in a solution stock 9 and pressurized by a solution pump 20 and set to a predetermined flow rate by a solution control valve 16. Thereafter, the absorption solution enters the innermost pipe of an absorber 1 and is heat-exchanged with cooling water sent from a cooling water tank 7 via a cooling water line 3, thus dropping from the top part of the absorber 1 along the outer side in a filmy state. Upon this occasion, vapor generated by an evaporator 2 is absorbed, and absorbed heat is discharged to cooling water. The absorption solution again returns to the solution stock 9, and to thin the absorption solution and is recirculated.

Title: Method for setting shape target value in cold rolling
Inventor: MIYANAGA TETSUO
IPC: B21B37/28
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To control both of the flatness and the profile of a product in the range of required values by calculating a shape objective correcting value from the plate thickness distribution of a rolled base stock and setting a corrected coefficient value according to a product rolled material. SOLUTION: In a cold-rolling mill, the plate thickness distribution in the width direction of the rolled base stock inserted into the rolling rolls is measured. A profile index is calculated from this plate thickness distribution. The shape objective corrected value is calculated based on the calculated profile index, and the plate width of the product after rolling and the corrected coefficient value according to the plate width are set. Then, the shape objective value is corrected based on the shape objective corrected value and the corrected coefficient value. The shape control is executed by using this shape target corrected value.  By this method, in the case of desiring to objective precedence of the correction of a ratio of high edge parts over the correction of a ratio of high center parts, the finishing to a desired product profile can be obtd. by setting a shape objective corrected value for making the ratio of high edge parts small.
