Cross-Review of Technical Documentation for Cement Clinker and Grinding: Multi-Turn Dialogues and Prompt Engineering

Production data for cement clinker and grinding comes from online composition analysis, DCS systems, laboratories, kiln and grinding equipment, raw

What the data for this category looks like

Production data for cement clinker and grinding comes from online composition analysis, DCS systems, laboratories, kiln and grinding equipment, raw and fuel ledgers, and energy metering devices. Data update cycles fall into three categories: real-time, shift-based, and daily. Daily generated documents include raw material batching plans, kiln operation logs, laboratory reports, quality control notices, equipment inspection records, and energy reports. Document fields cover raw material batching parameters, clinker free calcium oxide content, grinding specific surface area, equipment operating energy consumption, and other relevant metrics. Corresponding units include %, m²/kg, kWh/t, and similar units.

Data sources for this category are scattered, and update cycles vary significantly. Multi-turn dialogues must match update frequencies by data type. This avoids calling expired inspection records or outdated batching plans. Multiple document types have dedicated field and unit specifications. Prompt engineering must explicitly specify the target document type and corresponding fields during retrieval. This prevents confusion between different parameter meanings. Core review workflows include batching adjustments amid raw and fuel fluctuations, and stable thermal control of rotary kilns. These require retaining historical parameter context from multi-turn interactions. This ensures each query can link to earlier production data, and avoids repeated input of duplicate information.

Configuration Settings

This configuration is based on FastGPT v4.17.0.

Configuration ItemRecommended ApproachRationale
Session IdentifierBind chatIdDistinguish review sessions for different shifts and equipment, avoid context confusion
Dialogue Context RetentionRetain the most recent 15 turns of interaction content in messagesCement production parameters are closely correlated, so recent historical dialogue content for batching and kiln temperature data must be retained
Variable InjectionBind real-time data fields in variablesDirectly call real-time parameters from online composition analysis and DCS systems into dialogue context
Single Retrieval LimitTop 5 matching documentsCover multiple production document types including raw material batching plans and laboratory reports
Single Document Truncation800–1200 charactersAdapt to the length of various production documents, control model input load
Question Optimization TriggerCalibrate based on actual measurementsAdapt to scenarios such as batching adjustments amid raw and fuel fluctuations, and kiln thermal system optimization

Three Common Misconfigurations

  • Symptom: Workflow output includes text wrapped in uncleaned thinking tags. Cause: The messages field from model outputs was not fully stripped of tags in the workflow's code run node, and processing was only completed in the debug environment.
  • Symptom: The number of documents returned by retrieval does not match the configured limit, or returned content exceeds the expected length. Cause: Truncation rules were not set based on the category's document length, leading to loss of critical parameters after long documents are truncated.
  • Symptom: Context becomes disorganized after multiple turns of dialogue, with review data from different shifts interfering with one another. Cause: chatId was not bound as the session identifier, leading to confusion between the context of different sessions.

How to Confirm the Configuration Is Properly Set

  • Initiate multiple rounds of queries targeting raw material batching plans, check whether the dialogue context retains the most recent 15 turns of interaction content.
  • Verify that the session's chatId corresponds one-to-one with the current shift and equipment under review, to avoid cross-session data confusion.
  • Trigger the question optimization function, confirm that it can automatically adjust queries to adapt to scenarios such as batching adjustments amid raw and fuel fluctuations.
  • Check that documents returned by retrieval are truncated to 800–1200 characters as configured, with no overflow of overly long content.
