The blast furnace was ignited at 23:16 on October 31, iron tapping started smoothly at 15:50 on November 1, and the coal injection system was commissioned on the same afternoon. Between October 31 and November 1, the process measurement and automation control system project for the integrated restructuring, capacity reduction and replacement project (Phase II blast furnace and coal injection works) of Tangshan Ganglu Iron and Steel Co., Ltd., undertaken by MCC Huatian Nanjing Electric Company, was successively put into operation. All systems are running stably at present. The on-site technical team provides round-the-clock support to guarantee production, demonstrating MCC Huatian’s technical strength and reliable delivery capacity in industrial electrical engineering.
This project is a key supporting facility for the integrated restructuring and capacity reduction replacement of Tangshan Ganglu Steel. MCC Huatian Nanjing Electric provided a complete automation solution for the blast furnace and coal injection units. The blast furnace scope covers the full process of stockyard and batching system, furnace top system, hot blast stove system, pump house system, furnace body system and dry dedusting system. Services include automation system design, supply of automation and instrument equipment, and programming and commissioning of Level 1 and Level 2 automation systems. The coal injection unit received the same full-range automation engineering services. After commissioning, the project will improve intelligent control and operational efficiency of the Phase II blast furnace and coal injection processes. It delivers core technical support for the enterprise to meet capacity reduction replacement requirements and achieve quality and efficiency improvement, and facilitates the transformation of its production system toward lean, green and intelligent operation.
After the contract was signed on March 23, 2026, Nanjing Electric attached high priority to the project and set up a project team immediately. The team coordinated the whole workflow including electrical-instrumentation drawings review, PLC package design, ordering, equipment supervision, delivery and on-site commissioning. All departments collaborated closely to meet the schedule. Major equipment was delivered to site by the end of June, laying a solid foundation for subsequent commissioning. Senior engineers optimized electrical and instrumentation procurement drawings to avoid common design defects and reduce on-site rework risks. Standardized frameworks and structured programming were adopted to improve program reusability and facilitate HMI optimization. The team aligned with the owner’s operational requirements and habits in advance and completed software pre-testing to shorten on-site commissioning time. Faced with tight commissioning schedule caused by labor shortage and slow preliminary coordination from the construction contractor, sufficient preparation and pre-testing enabled fast commissioning after single-point testing of each system, ensuring the scheduled startup.
