Abstract

Provided an optimizing apparatus comprising a setting calculation unit (31) for calculating a control setting value for a hot rolling apparatus (100) to roll a rolling material (120), on the basis of the initial sizes, the initial temperature and the target temperature of the rolling material (120), a working energy calculation unit (32) for calculating a working energy necessary for the hot rolling apparatus (100) to roll the rolling material (120), on the basis of the control setting value, a during-manufacture carbon dioxide discharge calculating unit (33) for calculating the quantity of carbon dioxide to be discharged in the hot rolling apparatus (100), on the basis of the working energy and the carbon dioxide discharge coefficient, and an optimizing unit (35); for calculating the target temperature both as the temperature at or higher than the value necessary for retaining the quality of the rolling material (120) to be rolled, and as a temperature for minimizing at least one of the working energy or the carbon dioxide discharge.

Description

technical field [0001] The invention relates to an optimization device for optimizing the control of rolling equipment, thereby ensuring the product quality of the rolled material when rolling the rolled material in the rolling equipment, and reducing the energy used and the carbon dioxide emitted At least one of the quantities is the smallest. Background technique [0002] Rolling facilities for rolling metal materials include thin plate hot rolling facilities, thick plate rolling facilities, cold rolling facilities for producing steel plates (hereinafter referred to as steel plates), steel section steel rolling facilities, bar steel and wire rods Rolling equipment, as well as aluminum and copper rolling equipment. [0003] For example, a hot thin plate rolling facility heats a cuboid steel material called a slab to about 1200° C. with a slab heating furnace 101 and rough-rolls it with a roughing mill to obtain a strip with a thickness of about 30 to 40 mm. At this time, ...
