Challenge

Tackling Operational Inefficiencies

The steel plant operated large-scale furnaces used for melting and heat treatment processes. However, several operational limitations were affecting performance and profitability:

Inconsistent Furnace Temperatures

Resulting in non-optimal combustion and thermal inefficiency.

Improper Fuel-Air Ratios

Causing excessive fuel use and raw material waste.

Manual Adjustments

Dependent on operator intuition rather than predictive analysis.

Rising Operational Costs

Due to inefficient energy use and material wastage.

Regulatory Pressures

Increasing need to comply with energy efficiency norms and emission standards.

These issues culminated in higher production costs, greater environmental impact, and limited responsiveness to real-time operational deviations.
