REHEATING FURNACE REGULATION
Our approach in reheat furnaces automation - either new and/or existing ones - passes through different levels to optimize efficiency and performance for control loops, handling and regulation in each stage of:
• Pre-reheating area
• Reheating area
• Left equalization
• Right equalization
We implement all the instrumentation of:
– Sensors
– Actuators
– Motors
– Drives
– Loop furnace temperature
– Loop zone regulation
– Regulation of airflow and gas flow
– Loop fumes temperature
– Loop combustive air and furnace pressures
– Tuning regulators
– Cold change / Hot change & combined
– Indirect/direct furnace cooling supervision
– Safety interlocks
– Instantaneous indicator of gas flow
– Gas consumed / work shift with the trend
– Gas consumed / billet (cost control)
– Tracking control along the furnace
– Heating curve & Target temperature
– Consumption trend & analysis
– Thermal model
