Problems solved by technology

At present, in the actual steelmaking production process, the management of ladles is relatively chaotic, and the records of ladle-related information are completed manually and the recorded information is not complete. Since the complete information of ladles cannot be obtained in time, the dispatcher only considers putting the qualified ladles that meet the production requirements into turnover. , but neglected to put in the most reasonable steel ladle from among the many steel ladles that meet the online requirements. There may be safety problems in the use of ladles

Abstract

The invention provides a fine management method for steel ladles of a steel plant. The method is characterized in that steel ladle related information is divided into overall information, energy consumption related information and safety related information; the overall information comprises steel ladle number, state, the ladle life of big repair ladles, the ladle life of small repair ladles and position; the energy consumption related information comprises standby time, roasting time and the quantity of residual steel; the safety related information comprises the using times of a molten pool, the using times of a water inlet, the using times of a water outlet, the using times of a sliding plate, the using times of an air brick and the using times of a stag line; the energy consumption related information determines the molten steel compensation temperature of the steel ladles at each procedure; and the safety related information determines whether the steel ladles can be safely used in the next period or not. With the method, a basis is provided for precise temperature compensation and a decision is provided for safety application of the steel ladles through dynamic maintenance of the overall information, the energy consumption related information and the safety related information in the steel ladle transfer process, so that the fine management level of the steel ladles of the steel plant is increased.

Description

technical field [0001] The invention relates to the field of management of ladles in steelworks, in particular to a fine management method for ladles in steelworks. Background technique [0002] Ladle is an important reaction vessel for containing and transporting molten steel and carrying out corresponding secondary metallurgy. In the steelmaking production process, the ladle is responsible for the important task of molten steel transfer, which is closely related to the stable control of the molten steel temperature and the process time rhythm and logistics control in the steelmaking plant. Realizing the refined management of the ladle has the following significant significance: reducing the empty ladle standby time of the ladle, increasing the red bag tapping rate, reducing temperature compensation, and reducing the tapping temperature of the converter molten steel; reducing the holding time of the empty ladle of the ladle, saving gas consumption, Reduce emissions and imp...
