Powerful performance
Achieving fast and accurate control of torque and speed under all working conditions is
The important prerequisite for successfully controlling profiles, thickness, flatness, and tension within the steel rolling mill
Decision making conditions.
ABB's motor control platform - Direct Torque Control (DTC), capable of achieving medium voltage
The highest torque and speed performance that a frequency converter can achieve. This system ensures that
Immediate and stable control of the equipment under conditions.
power factor correction
The impact of industrial production on the power supply system is often underestimated. There are difficulties in the metallurgical process
Difficult situations, where significant changes in load and large speed controlled frequency converters can cause voltage fluctuations
Deviation and harmonics. Optimizing the selection of frequency converters can minimize interference to the greatest extent possible
Compensate for reactive power demand.
regenerative braking
For equipment with high braking energy such as reversible rolling mills, ABB can provide a frequency converter solution
Case, optimize energy flow. The braking energy can be fed back to the power grid, thereby reducing the total energy consumption.
The benefits brought to the steel rolling mill
Using DTC to achieve fast and accurate torque and speed control under all conditions
Multiple motors can be connected to a multi drive system
Regenerative braking function
Minimize system energy consumption to the greatest extent possible
ABB inverter universal control system
Easy connection to upper level automation systems
- Achieve optimal power factor across the entire speed range
By optimizing the pulse mode, the harmonic content is minimized to the greatest extent possible
Multi motor operation
ABB can provide solutions that support the operation of multiple motors. In a multi motor operating environment
Multiple motors can be connected to a multi drive system, allowing for different frequency conversions
Realize energy flow between devices. By utilizing a multi drive system to control the rolling mill, it is possible to achieve
The energy regenerated from the process in braking mode is directly used for another process, without
Consume electricity from the power grid.
conserve energy ,reduce emissions
Due to the fact that pumps and fans typically operate at partial loads, frequency converters are utilized
Controlling its rotational speed can greatly save energy. Slightly reducing the rotational speed can significantly decrease it
Energy consumption. When the pump or fan is running at half the speed, the energy consumption is only at full speed
One eighth of it.
By using frequency converters to control centrifugal pumps and fans instead of throttling or blocking
Ni or imported guide vane control can reduce energy costs by up to 60%. So, using
Frequency converters also help reduce emissions of nitrogen oxides and carbon dioxide.
Soft start
Utilize heavy-duty torque and/or high-quality inertia moment to accelerate the speed of the motor, such as blast furnace drum
Wind turbines can generate significant stress on the mechanical components of the power supply network and shaft system. direct
Starting the motor online will result in a starting current six times the rated current. This will
Causing a voltage drop, which is likely to interfere with the process, especially in power supply
When the network is relatively fragile.
Frequency converters used as soft starters can reduce the impact on power supply networks, motors, pumps, and fans
The stress generated. During the starting process, the frequency converter gradually increases the motor speed, which can
Smoothly accelerate the load to the rated speed.
Soft starter can eliminate high starting current and voltage dips that can cause process tripping
Elephant. With the help of soft starters, maintenance costs can be effectively reduced and equipment operation can be extended
