METHOD AND SYSTEM FOR CONTROLLING AIR QUANTITY OF AIR BOX OF SINTERING TROLLEY

摘要

A method and a system for controlling air quantity of an air box of a sintering trolley. A valve is disposed on each air box of the sintering trolley. The method comprises: acquiring air quantity data of a specified air box of the sintering trolley; adjusting a valve opening degree of another air box according to the air quantity data of the specified air box and a relationship between the air quantity of each air box in a database and the valve opening degree of a corresponding valve, so as to enable the air quantity of another air box to be consistent with the air quantity of the first specified air box. Because the actual air quantity in the air box is consistent with required air quantity as far as possible, and therefore, the situation is avoided that the proportion of the effective air in the air box is gradually decreased, thereby greatly decreasing air waste and more effectively saving energy sources. By means of the method, it can be ensured that the vertical sintering speed is not excessively high, and the invalid air quantity is decreased when the sintering ore quality is ensured.
