Industry Background

From Experience-Driven to Intelligent Manufacturing

Steel production involves long process chains, complex operating conditions, and tightly coupled workflows — where precise control of process parameters directly determines product quality, energy consumption, and operational efficiency.

Complex Process Conditions
Long production chains and complex operating conditions make precise process parameter control critical to product quality and energy efficiency.
Vendor Lock-In and High Integration Costs
Dependence on proprietary industrial software creates long-term vendor lock-in, high licensing costs, and limited flexibility for customization and integration.
Challenges
Siloed Production Data
Multi-process operations across equipment, production lines, MES, and ERP systems generate fragmented, heterogeneous data, making unified management and real-time cross-system coordination difficult.
Experience-Driven Optimization
The relationships between process parameters, product quality, and energy consumption lack systematic modeling. Production scheduling and equipment control rely heavily on manual expertise, resulting in inefficient energy use and carbon reduction targets that remain unmet at the production level.
Reactive Quality Control
Processes such as pellet roasting rely on fixed control logic, leading to parameter deviations and thermal fluctuations. Quality management is largely post-hoc, with limited real-time monitoring capability and high defect rates.
Performance Bottlenecks at Scale
Traditional platforms struggle to handle high-concurrency time-series data ingestion, real-time analytics, and cross-process correlation at the scale steel production demands — limiting the potential of digital transformation initiatives.

DolphinDB Solution

Data ArchitectureTechnical Architecture

Multi-Protocol Data Ingestion

Built-in OPC UA, ODBC, and other protocol plugins enable unified connectivity across production equipment and business systems — no custom development required, with centralized interface management and multi-source data consolidation.

Real-Time Monitoring and Alerting

A real-time monitoring pipeline for roasting and other core processes ingests process parameters into stream tables, computes rolling means, variance, and rate of change via window calculation, and triggers instant alerts when values exceed preset thresholds.

In-Database Computation

Rich built-in functions and vectorized operations support model building and optimization solving in one place. Deep integration of stream processing and machine learning enables real-time inference with millisecond response and strong generalization across process conditions.

High-Concurrency Architecture for Industrial Scale

Designed for high-concurrency ingestion and analysis of massive time-series datasets, DolphinDB supports real-time process control and intelligent optimization at production scale — with a flexible architecture that integrates into existing industrial environments without vendor lock-in.

Key Benefits

Precision Process Control

Low-latency stream processing and model integration enable precise parameter control across the full production line — reducing process deviations, minimizing equipment downtime, and stabilizing thermal conditions to improve product consistency.

Energy Efficiency and Emissions Reduction

By uncovering relationships between process parameters and energy consumption, DolphinDB drives optimization of equipment and production line strategies — significantly reducing overall energy use while maintaining output and quality targets.

Reusable, Adaptable Modeling

Physics-informed and data-driven modeling built on DolphinDB's native compute capabilities produces generalized models that can be reused across production lines and adapted to dynamic process changes — accelerating the scaling of digital initiatives.
