We are a China-orientated silicon steel manufacturer with 20 years of experience in this industry. We provide high-quality oriented silicon steel, mainly serving the variable pressure industry and related fields. While guaranteeing the quality of our products, we focus on providing one-stop services and solutions to make our customers more efficient.
We have a deep knowledge of silicon steel, and here we will share the history of silicon steel so that you can know more about silicon steel and us!
1. The Early Days: Introduction and Digestive Period (1974-1986)
In 1974, with the approval of the state, Wuhan Iron and Steel Group first introduced the world's advanced patented technology and complete process production equipment for cold-rolled electrical steel from Nippon Steel in Japan. The annual production design capacity of this project is 70000 tons, including 42000 tons of non-oriented steel and 28000 tons of oriented steel (including HIB steel). The project started construction on September 5, 1974, and was put into trial operation in the second half of 1978. It generated economic benefits that year and contributed to replacing imported-oriented silicon steel products.
2. Advancing Through Innovation: Introduction and Absorption Period (1987-1997)
This phase focused on mastering imported technologies while innovating to meet domestic demand for high-performance electrical steel. Key achievements included:
Stable production of high magnetic induction (HiB) steel.
Development of domestic magnesium oxide coatings, rolling mills, and annealing furnaces.
Establishing the world's first double-layer continuous annealing furnace for silicon steel.
China also built 23 production lines, setting the foundation for a robust domestic silicon steel industry.
3. Rapid Growth: Global Leadership Period (1998-2024)
From 1998 onward, China's CRGO steel production has seen remarkable advancements, leading the world in output and technology.
In 2024, China produced 1.385 million tons of CRGO steel, with HiB steel accounting for 70% of the total.
Thin silicon steel (≤ 0.20 mm) production has surged, meeting global demand for high-efficiency transformers.
Production facilities now number 27 nationwide, with annual growth rates reaching 5%.
Global Transformer Market: Opportunities for Growth
The global transformer market continues its upward trajectory, with an 8%-10% annual growth rate in 2024.
Key Market Insights:
Regional Demand: The Asia-Pacific region dominates global demand, followed by North America.
Trade Leaders: The U.S., U.K., and Germany are major importers, while China, South Korea, and Mexico lead exports.
Future Trends: Efficient energy solutions, digitization, and environmental sustainability drive innovation. CRGO steel grades above 0.85 mm are in high demand for next-generation transformers.
