On April 9, 2023, the first coil of non-oriented silicon steel was successfully produced by the No. 1 continuous annealing unit for non-oriented silicon steel, designed and constructed by Huangshi Shanli Technology Co., Ltd. (hereinafter referred to as "Shanli Company") for Chifeng Yuanlian Iron & Steel Co., Ltd. in Inner Mongolia. This marks the successful commissioning of the No. 1 unit of Yuanlian Steel's 140,000-ton annual production project for non-oriented silicon steel.

On April 9, 2023, the first coil of non-oriented silicon steel from the No. 1 non-oriented silicon steel continuous annealing unit of Chifeng Yuanlian Iron and Steel Co., Ltd. in Inner Mongolia, designed and constructed by Huangshi Shanli Technology Co., Ltd. (hereinafter referred to as "Shanli Company"), was successfully produced, marking the successful commissioning of the No. 1 unit of Yuanlian Steel's 140,000-ton annual production of non-oriented silicon steel project.

In the first half of 2022, Huangshi Shanli Technology Co., Ltd. and Chifeng Yuanlian Iron and Steel Co., Ltd. reached a business cooperation agreement based on mutual trust through online communication. Adhering to the principle of customer first, Shanli Company adopted a turnkey project approach to design and construct two 140,000-ton/year continuous annealing and insulating coating units for medium and low grade non-oriented silicon steel for Yuanlian Steel. In November 2022, with the active cooperation of Yuanlian Steel, the installation of the No. 1 unit officially began. Despite the severe cold weather with temperatures as low as -20 degrees Celsius, the design and construction departments of Shanli Company overcame difficulties and devoted themselves to the project construction. After five months of hard work, the No. 1 unit was debugged in early April 2023 and successfully started production at the first attempt.

This project mainly involves the construction of two continuous annealing and insulating coating units for medium and low grade non-oriented silicon steel. Their function is to degrease the surface of cold-rolled non-oriented steel strip and anneal it in a protective atmosphere to eliminate stress and increase grain size, improving magnetic properties and applying an insulating coating. Both units have a maximum processing capacity of 140,000 tons/year, a maximum speed of 120 m/min, and process steel strips with specifications of 0.35-0.65 mm (thickness) × 550-800 mm (width).

Shanli Company warmly congratulates Yuanlian Steel on achieving product transformation and wishes its partners continued success in exploring new markets and meeting the opportunities and challenges ahead.
