Three-dimensional positioning method for automatic slagging-off of desulfurized molten iron

Abstract

The invention provides a three-dimensional positioning method for automatic slagging-off of desulfurized molten iron. The method comprises the following steps of establishing an original data model, calculating the minimum lifting height H1, the maximum lifting height H2, the minimum extension distance C2, the maximum extension distance C3 and the rotation angle value T of a slagging-off machine, and sequentially controlling the lifting height, the rotation angle and the extension length of the slagging-off machine according to the calculated data to carry out automatic slagging-off operation. The situation that errors are too large during manual operation and the slagging-off effect is sometimes good or sometimes bad is avoided, the influence of personal errors on the slagging-off effect is reduced, the inclination angle of a tank body during slagging-off is determined, three-dimensional coordinates needing to act of the slagging-off machine are calculated through a certain method, and the slagging-off operation is carried out according to the set coordinates; and meanwhile, the three-dimensional coordinates are continuously changed, an area needing slagging-off is determined, automation of the slagging-off process is achieved, manual participation is reduced, the slagging-off efficiency is improved, the workload of workers is reduced, and harm caused by molten iron spray explosion to operators in the slagging-off process is reduced.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a three-dimensional positioning method for automatic deslagging of desulfurized molten iron. Background technique [0002] In the field of industrial production, the desulfurization area of ​​converter steelmaking uses a ferry car with a tilting function to operate. The molten iron tank is placed on the tipping car, and then it is transferred to the injection position for injection operation. Tilt the tank body to the position where it can remove slag. During the slag removal process, since the conditions of each molten iron tank filled with molten iron are different, the amount of slag hanging in each molten iron tank is also different. The operator tilts the molten iron tank After arriving at the position, operate the slag removal machine to carry out the slag removal operation, because the slag removal effect is unstable during the manual slag removal operation, often the r...

[0002] In the field of industrial production, the desulfurization area of ​​converter steelmaking uses a ferry car with a tilting function to operate. The molten iron tank is placed on the tipping car, and then it is transferred to the injection position for injection operation. Tilt the tank body to the position where it can remove slag. During the slag removal process, since the conditions of each molten iron tank filled with molten iron are different, the amount of slag hanging in each molten iron tank is also different. The operator tilts the molten iron tank After arriving at the position, operate the slag removal machine to carry out the slag removal operation, because the slag removal effect is unstable during the manual slag removal operation, often the removal is not clean or the removal rate is high, and the slag removal time is long, resulting in waste of molten iron and at the same time causing The process requires further processing, prolonging the production cycle
