Intelligent slag salvaging control method and device

Abstract

The invention relates to the technical field of hot galvanizing, in particular to an intelligent slag salvaging control method and device. The method comprises the steps that the zinc slag thicknessesof all slag salvaging areas on the liquid level in a zinc pot are obtained; the slag salvaging areas needing to be subjected to slag salvaging operation are determined; all the slag salvaging areas needing to be subjected to slag salvaging operation are used as path nodes, and a path node set is constructed; the path node set is traversed, and a slag salvaging path set is constructed; the evaluation index of each slag salvaging path is obtained according to the total length of each slag salvaging path in the slag salvaging path set and the weight of the zinc slag; and a slag salvaging mechanical arm is controlled to execute slag salvaging operation according to the slag salvaging path corresponding to the maximum evaluation index in the slag salvaging path set. According to the method, the slag salvaging control of the slag salvaging mechanical arm is converted into the optimal path problem about how to achieve the shortest path and the maximum slag salvaging quality on the premise that the upper limit exists in the single-time slag salvaging capacity, the slag salvaging path with the maximum evaluation index is used for controlling the slag salvaging mechanical arm to conduct slag salvaging operation, and therefore the slag salvaging operation efficiency of the slag salvaging mechanical arm is improved.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing, in particular to an intelligent control method and device for slag removal. Background technique [0002] Zinc slag is the most common defect on the coating surface of continuous hot-dip galvanized steel strip. The main reason for its occurrence is that the three-phase balance of iron, aluminum and zinc in the zinc pot is broken due to changes in the temperature of the strip steel, the temperature of the zinc pot, and product specifications. As a result, intermetallic compounds with different components are produced, which respectively present three forms of surface slag, suspended slag and bottom slag according to their different specific gravity. Effectively control the suspended slag in the zinc liquid, timely remove the surface slag in the V-shaped area of ​​the zinc pot and the zinc slag in other hot-dip affected positions, and prevent the transformation and emergence of the bott...

Problems solved by technology

This method can basically realize the replacement of personnel, but there are still the following problems: the efficiency of slag removal is low; the ZnO layer that plays a protective role is also taken away as zinc slag, which makes the zinc consumption increase significantly
