Problems solved by technology

However, the feeding and spheroidizing inoculation treatment station is often relatively independent, and its automation focuses on its own process control and cooperation with the traveling equipment. On-site process changes or parameter changes need to be manually re-entered, which is an important part of the melting and pouring process. The intelligent implementation of wire-feeding spheroidizing inoculation stations is often limited to on-site automation conditions and equipment foundations, and cannot be economically and seamlessly integrated into the overall process control of smelting and pouring. Various monitoring and statistical tasks require manual assistance and reprocessing, such as : Application No.: 201420122263.5 patent discloses a forklift transport type spheroidization, vermicularization, inoculation processing station and application number 201420122251.2 discloses a crane transport type spheroidization, vermification, inoculation processing station, the above two This technical solution solves the problem that the route between the processing station and the pouring location is complicated, and the molten iron transportation time is long, which leads to the recession of the molten iron and affects the product quality. Island, the required existing chemical composition of molten iron (such as magnesium Mg, sulfur S, etc.), the weight of molten iron in the ladle, the temperature value, and the depth of molten iron in the ladle, as well as the actual execution results of spheroidizing inoculation (such as wire feeding Length, feeding time, etc.) data interaction requires manual input and copying, especially for smelting plants with a large workload, on-site operators need to reciprocate at least twice between the smelting control console and the spheroidizing inoculation station for data input and records, greatly increasing the human workload, and the correctness and real-time performance of data interaction cannot be guaranteed

Abstract

The invention provides a process control system and method. The process control system comprises a smelting control system and a PLC system of a wire feeding and nodulizing-inoculating treatment station, wherein the smelting control system is connected to the PLC system through a network; the smelting control system is used for obtaining relevant information of a smelting furnace and molten iron in the smelting furnace and relevant information of molten iron in a casting ladle and sending the information; and the PLC system is used for receiving the relevant information of the smelting furnace and the molten iron in the smelting furnace and the relevant information of the molten iron in the casting ladle and controlling parameter information of wire feeding according to the relevant information of the smelting furnace and the molten iron in the smelting furnace and the relevant information of the molten iron in the casting ladle. According to the process control system and method, through reasonable distribution, data interaction and step arrangement of the smelting control system and the PLC system of the wire feeding and nodulizing-inoculating treatment station, the nodulizing-inoculating process is seamlessly integrated into overall process control of smelting and pouring in an economical and simple mode, manual intervention in steps of the nodulizing-inoculating process is reduced, and intelligentization of partial steps is realized.

Description

technical field [0001] The invention relates to the field of cast iron, in particular to a process control system and method. Background technique [0002] Wire feeding technology is widely used in metallurgical steelmaking industry for desulfurization, oxygen removal, slag gas removal and alloying. With the progress and development of wire feeding technology, this technology is gradually being applied in the field of cast iron, especially suitable for nodular graphite, vermicular graphite and inoculum casting. This technology uses a steel strip to wrap a rare earth magnesium alloy in it with a cored wire machine to make an alloy cored wire, and then feeds it to the bottom of the molten iron processing ladle with a wire feeding machine, so that the wrapped material is at the bottom of the processing ladle and iron This technology is used for desulfurization, spheroidization and inoculation of molten iron, as well as real-time fine-tuning of magnesium, rare earth and other e...
