Embodiment Construction
[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0051] Such as figure 1 As shown, the embodiment of the present invention provides S10, start the automatic slag discharge, the slag truck moves to the linkage initial position, and the converter tilts to the linkage initial angle;
[0052] S20. The slag truck runs at a constant speed from the linkage initial position to the linkage end position, and calculates the inclination angle and the tilting speed setting value of the converter according to the actual v...

The present invention provides an automatic slag discharge control method and system for slag truck-converter linkage, the method comprising: starting automatic slag discharge, the slag truck moves to the linkage initial position, the converter tilts to the linkage initial angle; the slag truck moves at a constant speed from the linkage initial position Run to the end position of the linkage, calculate the inclination angle and tilting speed setting value of the converter according to the actual value of the position of the slag car; after the slag car and the converter reach the end position of the linkage, wait for several seconds to wait for the steel slag to be exhausted, and then the slag car and the converter move to automatic Slag discharge termination position. The invention realizes the automatic control of the slag discharge process of the converter. During the linkage process of the slag car and the converter, the set value of the inclination angle and the set value of the tilting speed of the converter are calculated in real time according to the actual value of the position of the slag car, thereby realizing two The high-precision automatic control of the equipment makes the steel slag just pour into the steel slag tank, which solves the problem of instability and poor precision of manual operation, reduces the labor intensity of the staff, and improves the efficiency and safety of the slag discharge operation.
Description
technical field [0001] The invention relates to the technical field of converter automatic control, in particular to an automatic slag discharge control method and system for slag truck converter linkage. Background technique [0002] Converter steelmaking is the most important steelmaking method in the world today, and steel production accounts for more than 65% of the world's total steel production. After the converter steelmaking is completed, the smelted molten steel should be poured into the ladle car, and then the steel slag in the converter should be poured into the slag tank car. Iron and steel production enterprises pay more attention to the blowing and tapping process, but not to the slag discharge process, but the requirements for personnel operation in the slag discharge process are not low. The existing converter slagging process is performed by the operator in the operating room in front of the furnace by operating the shaker handle and the slag car control ha...
