Product Specification

CRGO grain oriented electrical ei silicon steel width 980mm--1010mm

All the 110KV main transformers of large-scale rolling mills made of ultra-thin oriented silicon steel produced by Baosteel Co., Ltd. have been commissioned and loaded with various technical and economic indicators since the 2030 cold rolling unit test for one month, and the energy efficiency has been significantly improved.

This marks the increasingly mature production and application of Baosteel's ultra-thin oriented silicon steel products, breaking the long-term monopoly of imported products in the 0.2mm-oriented silicon steel in the field of power transformers, which is also the use of 0.2mm ultra-thin domestic industrial power products Oriented silicon steel to make iron core.

The ultra-thin oriented silicon steel represented by B20R070 is an important product representing the technical level and production organization capacity of Baosteel, and is also the main product after the subsequent engineering of oriented silicon steel is put into production. At present, this product is mainly used in S15 energy efficiency distribution products.

In order to promote the application of ultra-thin oriented silicon steel in the field of large-scale power transformers, expand the high-end user market, and accumulate practical application experience, in the fourth quarter of last year, Baosteel Co., Ltd. combined with the renovation and transformation of the main transformer of the 2030 cold rolling unit, decided to install two large In the change, the B20R070 ultra-thin oriented silicon steel is used to make the iron core instead of the original conventional iron core scheme. The smooth implementation of the project has realized the extension of the 0.2mm oriented silicon steel downstream market from power distribution to large power transformers.

At present, the production of ultra-thin oriented silicon steel and the application of transformers are mastered by only a few steel mills and transformer companies at home and abroad, and the technical blockade is tight and the exclusivity is strong.
