What Data for This Category Looks Like
Special steel spot prices and ex-factory prices come from monitoring data released by the domestic special steel industry association, price adjustment ledgers directly supplied by steel mills, and public data from special steel futures markets. Update rhythms are layered: ex-factory price data updates in real time alongside steel mill price adjustments, average spot price data updates daily, and overall industry monitoring data updates monthly. Each data entry includes fields such as product code, specification model, origin, ex-factory price, average spot price, and inventory turnover days. Field units: ex-factory price and average spot price use yuan/ton as the unit, inventory turnover days use natural days as the unit, product code is a 6-character alphanumeric combination, and specification model includes physical parameters such as diameter and thickness.
Constraints Imposed by These Characteristics on Forms and Interactions
The layered update rhythms of multi-source data require forms to support filtering data by time range, to prevent users from obtaining outdated or mismatched market information. The rich and highly personalized specifications of special steel require the specification selection control in the form to support fuzzy search and linkage matching, reducing page loading and selection costs. The multi-field information structure requires forms to adopt a grouped layout, dividing fields such as price, specification, and inventory into independent modules to simplify user filling and information viewing processes. Differences in the authority of different data sources require the interactive interface to mark data collection sources and update times, helping users distinguish real-time market information from historical monitoring data.
How to Configure Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
knowledge_base_select | Bind to the special steel industry-specific knowledge base | Match dedicated data sources related to special steel yield rates, avoid mixing irrelevant data from general steel categories |
max_context_length | 800–1200 characters | Adapt to the length of specification models and price information for special steel data, prevent truncation of key business fields |
search_relevance_threshold | 0.75–0.85 | Filter low-relevance general steel data, focus on precise matching results for special steel segment categories |
stream_response | true | Adapt to the streaming output requirements of real-time market reports, improve interactive response speed |
parse_timeout | 300 seconds | Address parsing delays during multi-source data integration, avoid task interruption due to timeout |
form_field_grouping | Enabled | Divide fields such as price, specification, and inventory into separate groups, simplify form filling and viewing logic |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- When setting
stream_responsetotruevia API call, only partial segmented data is received, and the complete result is not obtained. Cause: No result aggregation logic is configured, and thedonestatus field for streaming returns is not monitored. - An empty special steel data result is returned after form submission. Cause: The dedicated special steel knowledge base is not bound, and incorrect selection of a general steel knowledge base leads to data matching deviations.
- A
408 Request Timeouterror is prompted during form loading. Cause: Theparse_timeoutparameter is not adjusted, and multi-source data integration time exceeds the default threshold.
How to Confirm Successful Configuration
- Open the knowledge base selection control, confirm that only the special steel industry-specific knowledge base is bound, and no other category data sources are included.
- Submit a test form, select any special steel product and a reasonable time range, check if the returned result fields include exclusive special steel information such as specifications and origin.
- Enable the streaming response switch, call the test API, confirm that complete segmented data can be received and aggregated into a final result.
- Check the form layout, confirm that fields such as price, specification, and inventory are divided into groups, with no overlapping or missing content.
