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
