Quality Problem Traceability and Defect Analysis for Iron and Steel Smelting and Continuous Casting: HTTP Interfaces and External Systems

Data sources for this category include raw hot metal and scrap data, real-time operation data collected by L2 process control, composition test

What This Category of Data Entails

Data sources for this category include raw hot metal and scrap data, real-time operation data collected by L2 process control, composition test results from the laboratory, production scheduling records from the MES system, energy consumption data from the energy medium system, and equipment status monitoring data. Daily production documents include heat plans, batching lists, converter smelting records, continuous casting process records, and slab judgment sheets. Data updates sync per heat, real-time, and shift cycles. Core fields include heat number, cast sequence identifier, smelting temperature, equipment operating parameters, composition test indicators, and defect judgment results. Data length changes dynamically with heat production links.

Constraints for HTTP Interfaces and External Systems

This category of data is multi-source, dispersed, and has large differences in update rhythms. Real-time data requires millisecond-level synchronization. Heat-level data must be associated by production batch. HTTP interfaces must support pulling associated data sets by unique heat number or cast sequence identifier. Field structures of multiple data sources vary greatly. Interfaces must support flexible specification of returned fields to avoid redundant data transmission. High-temperature continuous production processes do not allow arbitrary shutdowns. Interface calls must have timeout fault tolerance and idempotency guarantees. This prevents production traceability processes from being interrupted by a single failed call. Shift-based batch summary statistical data must support paginated pulling. This adapts to system data volumes of different scales.

Retry count3 retriesPrevents traceability processes from being interrupted by single call failures in high-temperature continuous production
Single pull data volume100–500 recordsAdapts to transmission bandwidth and processing efficiency of multi-source data

Three Common Misconfigurations

  • Interface calls return 401 Unauthorized, with incorrect authentication information carried. The cause is failure to configure the Authorization parameter according to specifications, and failure to generate an authentication token that meets third-party system requirements.
  • Target data fields returned by the interface are empty, unable to match production traceability requirements. The cause is failure to pass correct heat number or cast sequence identifiers in variables, so corresponding batch production data cannot be associated.
  • Abnormal format errors are returned when calling a third-party analysis model. The cause is failure to specify return field rules adapted to model output in responseData, leading to inability to correctly parse model return results.

How to Verify Successful Configuration

  • Call the specified interface, pass a verified heat number or cast sequence identifier, check if the returned responseData includes expected production record fields.
  • Simulate a single call failure scenario, check if the system automatically initiates retries according to the configured retry count, and does not interrupt the current traceability process.
  • View authentication logs, confirm that the format of the Authorization parameter meets the authentication requirements of the third-party system, with no authentication failure records.
  • Adjust the associated parameters in variables, verify that the data returned by the interface updates synchronously as the parameters change.
