摘要:
An operation support apparatus includes a display device (16) displaying a setting screen including an operating instruction information setting section in which operating instruction information related to the operating instruction is set and an applicable condition setting section having a menu for setting an applicable condition when notifying the operating instruction information. A CPU (11) selects one item from display items in the menu based on an operating input by a PD (14), and performs control to change and display display items in a lower menu below the menu depending on the selected item.
摘要:
The present invention provides a cooling control method which comprises calculating cooling conditions required for cooling the steel plate to a predetermined temperature for a plurality of positions inside a cooling apparatus based on measured temperatures at a time when the steel plate passes through the cooling apparatus by a thermometer disposed at the entry-side of the cooling apparatus and setting a cooling schedule, calculating a heat transfer coefficient from the set temperature and a cooling water density for cooling one surface of the steel plate, calculating a cooling top water density from the calculated heat transfer coefficient, and controlling the amounts of cooling water of the cooling apparatus based on the ratio of the cooling bottom water density and cooling top water density so as to cool the steel plate to a predetermined cooling end temperature.
摘要:
A cooling control method which quickly controls the amounts of cooling water sprayed from top and bottom surfaces of the cooling apparatus when cooling steel plate to a predetermined cooling end temperature so as prevent shape deterioration of steel plate occurring due to the difference of cooling rates between the top surface and the bottom surface with a high precision, that is, a cooling control method of calculating cooling conditions required for cooling the steel plate to a predetermined temperature for a plurality of positions inside the cooling apparatus based on measured temperatures at a time when the steel plate passes through the cooling apparatus by a thermometer disposed at the entry-side of the cooling apparatus and setting a cooling schedule, calculating a heat transfer coefficient from the set temperature and a cooling bottom water density, calculating a cooling top water density from the calculated heat transfer coefficient, and controlling the amounts of cooling water of the cooling apparatus based on the ratio of the cooling bottom water density and cooling top water density so as to cool the steel plate to a predetermined cooling end temperature, thereby simplifying the amount of calculation required for controlling the amounts of cooling water sprayed from the top and bottom surfaces of the cooling apparatus.
