An Empty Ladle Correction Method for Steel-making Folding Can Hot Metal Metering System

Abstract

The invention relates to an empty package correction method for a steelmaking pouring tank molten iron metering system and belongs to the technical field of overhead crane positioning and weighing measurement of a steelmaking plant. The technical scheme is that the events of sitting package and hanging package of a pouring tank are judged by using the change of a pouring tank flat car weight and aflat car number of the hanging package or the sitting package is recorded; an overhead crane positioning system finds a sitting package time by searching a flat car number in lifting the pouring tank; then an event generated by judging the change of the overhead crane in the same time interval is found, the real-time accurate tracking of a pouring tank empty package is achieved, and therefore, the high accuracy of metering and collection of pouring tank molten iron is achieved. The method has the advantages that the qualitative judgment is carried out through the change of the pouring tank flat car weight, the quantitative calculation is carried out by using the overhead crane large car positioning, the increase of equipment investment is not needed, the real-time and accurate correctionof the pouring tank empty package is achieved, therefore, the high accuracy of the collection of slag-containing molten iron is achieved, and the cost control is facilitated.

Description

technical field [0001] The invention relates to an empty ladle correction method of a steelmaking folding pot molten iron metering system, and belongs to the technical field of crane positioning and weighing metering in a steelmaking plant. Background technique [0002] The main function of the folding pot room in the steelmaking plant is to tip the molten iron produced in ironmaking into the molten iron ladle for steelmaking, so as to facilitate the mixing of molten iron into the converter through the steelmaking crane for steelmaking production. The molten iron metering system for folding cans is the key metering system for the steelmaking weighing system. The accuracy of hot metal metering is directly related to the metering and settlement of hot metal between factories, and is related to the control of hot metal consumption indicators. At present, the weighing measurement of molten iron in most steelmaking plants adopts the crane positioning system to realize the method ...

AI Technical Summary

Problems solved by technology

If the positioning of the trolley is considered, the positioning of the can folding flat car can be realized for the correction of the empty ladle of the folding can. However, since the positioning of the trolley needs to be invested in equipment and operation and maintenance, the production cost will be increased.
