EMI Solution

GrafTech, a manufacturer of graphite electrodes critical to electric arc furnace (EAF) steelmaking, lacked real-time visibility into furnace operations across its facilities. Maintenance teams operated reactively — addressing equipment failures after they occurred rather than anticipating them. In EAF steelmaking, unplanned downtime is particularly costly: a single furnace outage can halt an entire production run, while deferred maintenance accelerates electrode and equipment wear. Compounding the operational risk, the absence of centralized data collection made regulatory compliance reporting manual and time-intensive, adding administrative burden to an already demanding operating environment.

EMI Solution deployed Rockwell Automation's FactoryTalk VantagePoint software to give GrafTech centralized visibility into its electric arc furnace operations. The platform aggregates process data from disparate furnace systems into a unified monitoring environment, enabling operators and engineers to track trends, detect anomalies, and identify developing issues before they escalate into failures. The implementation included managed backup infrastructure and 24-hour system availability to ensure continuous data access. Critically, remote connectivity was built into the architecture from the outset — allowing engineering teams to diagnose furnace conditions without requiring on-site presence. Automated data collection was also configured to streamline regulatory compliance reporting, reducing the manual overhead previously associated with meeting industry requirements.

The deployment delivered an estimated $100,000 in financial savings, driven primarily by reduced unplanned downtime and lower maintenance costs. Key outcomes included:

• Remote troubleshooting capability reduced response times and on-site engineering visits during furnace issues
• Managed backups with 24-hour monitoring ensured continuous data availability and eliminated gaps in the operational record
• Improved compliance reporting replaced manual data-gathering processes with automated collection, saving time and reducing error risk

Beyond cost savings, GrafTech gained the trend-visibility needed to move toward proactive maintenance scheduling — a structural improvement in how the operation manages furnace health over time.

• Real-time data aggregation from electric arc furnaces is a prerequisite for shifting from reactive to predictive maintenance in metals operations.
• Remote access capabilities deliver measurable ROI by reducing the need for on-site engineering presence during troubleshooting events.
• Centralized monitoring platforms that also support compliance reporting address two distinct business problems with a single infrastructure investment.
• Managed backup and continuous availability SLAs are non-negotiable in high-stakes manufacturing environments where data gaps create both operational and regulatory exposure.
• Engaging a systems integrator with OT expertise accelerates deployment and reduces integration risk compared to in-house implementations.
