Application of FGI GT51 Series High Voltage Four-quadrant Frequency Converter in medium and thick plate coil plant
Under the background of complex and changing global economic situation and increasing uncertainty of supply chain, domestic steel enterprises are facing various challenges. In order to deal with the potential risk of technological blockade and supply chain disruption, accelerating the promotion of domestic alternatives has become an inevitable choice for the steel industry.
1.Customers need to request
In this context, a steel company in Nanjing has seamlessly replaced the fixed-size shear equipment of the medium and thick coil plant to achieve localization replacement, and solved the problem of supply chain and in-use equipment stopping production under the premise of improving production efficiency and quality.
2.FGI scheme
To meet the needs of a steel company in Nanjing, FGI provided a customized GT51 series high-voltage four-quadrant inverter solution. The solution is precisely matched to the main equipment parameters of the length shear, including 1400 tons of shear force, 225mm blade opening length, 7200mm blade radius, as well as 2*750KW motor power, 660V rated voltage and 1200 RPM rated speed.
In addition to the advantages of high control accuracy, strong overload capacity and high efficiency, GT51 series high voltage four-quadrant inverter also has the following characteristics:
High reliability, with long life device selection and a variety of protection guarantees, can resist harsh application scenarios, to ensure the steady operation of fixed size scissors.
High precision control, high dynamic response, can better respond to the running curve issued by PLC, better meet the shearing process requirements, improve the cutting speed.
Modular design takes up less space, quick plug design, easy module replacement, convenient maintenance.
By adopting FGI localization alternatives, medium plate factory received the following benefits:
cost reduction
For the first time, the medium and thick coil plant fixed length shear drive was made in China, and the cost was reduced by 40%-55%.
technological requirements
The FGI solution meets all process function and performance requirements.
building block design
The power unit replacement time is shorter, saving the customer's troubleshooting time.
utility rate of space
The space utilization is saved by about 50%.
technical support
FGI technical service team responds to customer needs in real time to solve customer worries.
The successful operation of FGI GT51 series high-voltage four-quadrant frequency converter in the medium and thick coil plant not only marks the breakthrough application of FGI transmission products in the steel industry, but also shows FGI's strength and innovation in the localization of substitution. In the future, FGI will continue to deeply cultivate the steel industry, provide more customers with customized and efficient transmission solutions, and help the steel industry achieve high-quality development.
