Problems solved by technology
[0002] Modern converters basically adopt top-bottom combined blowing and are equipped with sub-lances for automatic temperature measurement and sampling. During the smelting process, oxygen lances and sub-lances need to be controlled respectively, including the installation of sub-lance probes, measurement of sub-lances and sub-lances. Lifting, as well as the control of oxygen lance lifting and oxygen flow, which requires on-site control by the operator, which not only consumes the refining of the operator, but also increases the smelting time

Embodiment Construction
[0028] The purpose of the present invention is to provide a linkage control technology of converter double lances, realize the linkage control of oxygen lance and sub-lance, reduce the labor intensity of operators, reduce the extra time consumed by manual operation, and shorten the smelting cycle. The innovation of the present invention is to combine the control of the sub-lance with the control of the oxygen lance, the static model of the converter, and the dynamic model of the converter, so as to realize the linkage control of the sub-lance of the oxygen lance and provide strong technical support for the automatic steelmaking of the converter.
[0029] The above-mentioned purpose is achieved through the following technical solutions:
[0030] Converter double lance linkage control system, including oxygen lance sub-lance linkage control module, converter state tracking module, sub-lance control module, oxygen lance control module, static control model, dynamic control model, ...

The invention provides a converter double-lance linkage control system and a linkage control method. The converter double-lance linkage control system is used for oxygen lance and sublance linkage control and comprises an oxygen lance and sublance linkage control module, a converter state tracing module used for tracing state information in the converter production process, a sublance control module used for sublance control in the converter production process, an oxygen lance control module used for controlling ignition, ascending, descending and the magnitude of the oxygen blowing flow of anoxygen lance, a static control model used for calculating the amount of ingredients needing to be added and the needed total oxygen blowing amount to conduct static control over converter smelting, adynamic control model used for real-timely calculating the carbon content and the temperature of molten steel in the smelting process to conduct dynamic control over converter smelting, and an information collecting module used for collecting relevant data including converter oxygen blowing. Oxygen lance and sublance linkage control can be achieved, the efficiency is improved, manual operation isnot needed, and powerful technical support is provided for automatic steelmaking of a converter.
Description
Technical field: [0001] The invention relates to a converter double gun linkage control system and a linkage control method, belonging to the technical field of mechanical equipment. Background technique: [0002] Modern converters basically adopt top-bottom combined blowing and are equipped with sub-lances for automatic temperature measurement and sampling. During the smelting process, oxygen lances and sub-lances need to be controlled respectively, including the installation of sub-lance probes, measurement of sub-lances and sub-lances. Lifting, as well as the control of oxygen lance lifting and oxygen flow, which requires on-site control by the operator, which not only consumes the refining of the operator, but also increases the smelting time. For this reason, if there is a technology to realize the linkage control of the oxygen lance and sub-lance, it will definitely reduce the labor intensity of the operator, reduce the extra time consumed by manual operation, and shor...
