Maanshan Iron and Steel NATUS Technology Exchange Conference

On the morning of December 25, 2020, the NATUS product technical exchange was held at the Maanshan Iron and Steel Plant of China Baowu Iron and Steel Group.

Maanshan Iron & Steel is a holding subsidiary of China Baowu Iron and Steel Group Co., Ltd. It owns one A+H-share listed company and three New Third Board listed companies, as of 2019. Maanshan Iron & Steel Group produced 19.84 million tons of steel, with an operating income of 98.6 billion yuan. In the course of more than 60 years of hard work, self-accumulation and rolling development, Maanshan Iron and Steel has created many firsts in my country's steel industry. First: my country's first wheel and tire factory, the first set of high-speed wire rod rolling mill, "China Iron and Steel No. 1" , One "(A+H-share listed company), first, a large H-beam production line was born here successively.

NATUS attaches great importance to this product exchange meeting. The company sent core technicians to participate in this technical exchange meeting. The meeting was important, and more than 10 technicians from the Electric Power Department of Maanshan Iron and Steel Group were invited.

At the meeting, NATUS technical experts introduced NATUS high and low voltage cabinets and components. For the application in the steel industry, the application of NATUS vacuum circuit breaker NVT and frame circuit breaker 6NTA is mainly explained. NATUS vacuum circuit breakers have three types of rated voltages: 12, 24, and 40.5kV. The rated current can range from 630A to 4000A, and the rated short-circuit breaking current is from 20-50kA. The mechanical life and rated current opening of the 50kA circuit breaker in the heavy industry industry The number of interruptions can be done 10,000 times. 6NTA series frame circuit breaker is divided into 1600, 2500, 4000, 5000, and 6300 five kinds of frame current, and the volume of 5000A circuit breaker is only 566 X 450 X406.5 (3P), Icu can achieve 120kA, mechanical life and The electrical life is far beyond the industry standard. NATUS frame circuit breakers can be equipped with Modbus communication interface, which can provide a foundation for Maanshan Iron & Steel's intelligent power distribution platform in the future.

At the meeting, Maanshan Iron and Steel technicians listened carefully to the technical introduction and NATUS's intelligent power distribution scheme for the steel industry, and had a lively exchange and discussion on the current problems of various systems, upgrade schemes, and intelligent manufacturing. NATUS' NT6000 power The monitoring system and energy management system will provide a good solution for Masteel's intelligent power distribution management and operation and maintenance.

The participants said that through this exchange, they learned a lot of new knowledge and new understanding about power distribution intelligence, and also gained new understanding and understanding of NATUS, an electrical company originated in Germany.
