Embodiment approach 1

[0024] Embodiment 1: The ladle quantity calculation method of this embodiment is:

[0025] (1) Using the attached figure 1 The ladle operation process analysis method shown in the figure analyzes the ladle operation process of the 1# continuous casting machine in A steel plant, and it is concluded that the heavy ladle transportation path from the converter to the continuous casting machine is: converter-LF furnace-continuous casting machine ; The empty ladle transportation path from the continuous casting machine to the converter is: continuous casting machine-slag dumping position-repairing bag position-converter.

[0026] (2) Measure the time of each period in the ladle turnover cycle of 1# continuous casting machine:

[0027] The total time from the start of converter tapping to the start of casting of continuous casting machine: 78min

[0028] Continuous casting machine single furnace pouring time: 32min

[0029] The total time from the end of pouring to the start of ta...

Abstract

The invention relates to a steel ladle number calculation method applied to a steel works and belongs to the technical field of steel ladle control. Total time from tapping of a steel ladle converter to initial casting of a continuous casting machine, single-furnace casting time of the continuous casting machine and total time from casting ending to initial tapping are collected, and according to different numbers of casting times, the number of steel ladles is obtained when a single casting machine works or multiple casting machines work at the same time. According to the method, the reasonable using number of steel ladles of the single continuous casting machine can be calculated, and besides the most reasonable turnover quality of the steel ladles of the continuous casting machines can be calculated under the condition that overlapping time of heat numbers is different.

Description

technical field [0001] The invention relates to a method for calculating the number of steel ladles used in a steelmaking plant, and belongs to the technical field of ladle control. Background technique [0002] The ladle is the main container for carrying, refining and buffering molten steel at the interface between steelmaking and continuous casting. Its operating status is an important reflection of the operating efficiency of the steelmaking plant system. A scientific and reasonable calculation method for the number of ladles is of great significance for realizing the optimization of the production organization of the steelmaking plant . At present, there are few research results on the calculation method of the number of ladles. The existing results are mainly based on the output of the steelmaking plant within a certain period of time, combined with the smelting cycle of a single converter or the ladle pouring time of a single continuous casting machine to calculate th...
