Tundish Drying and Preheating System
Tundish drying and heating station
Tundish drying and heating station for melted steel placed in the aisle of continuous casting
Application: for drying and heating of tundish ladle refractory lining.
Fuel: Natural gas/ Corex/Mixed Gas / HFO / LDO
Tundish Station supporting frame completed with hydraulic equipment for lifting and lowering of burner and with hydraulic cylinders, fan and air delivery pipe for air delivering to the burner, gas distribution equipment with monitoring and control sensors and safety valve, local control panel,
Lifting and lowering frame with heating unit completed with:
Lined protective hood
Position sensors for movable frame
Gas pipeline and air pipeline
Flame and temperature control sensors
The drying and heating station shall ensure the drying up to 600°C during max. and heating up to 1100 – 1200°C during max.
The system is totally automatic control organized as a hierarchical many-level-system which includes:
Level for the control systems and the data collection systems from the technological sensors, regulators, actuating devices etc. (level 0)
Level for the automatic control and adjustment by means of controllers (level 1).
The automatic control systems have following functions:
Natural gas, compressed air and oxygen consumption control,
Instantaneous value recording for gas consumption and temperature with reference to the ladle number which will be entered by the operator at the start of the drying and heating process
Informing about the operating process and the equipment status,
Adjustment devices control while task entering in the visualization system,
System of the heating modes which shall be kept in the PLC. The possibility for modification of the modes by the process engineer and for choosing of the modes from the upper level of the control.
Automatic signalizing of the technological data deviation from the indicated limits or equipment failure, the personnel notification as well as the recording of such incidents,
Occasionally system blocking by safety reason,
Information exchange between the automation systems of the workshop,
Data storage for providing of operation history when required.
