Chinese Fujian Kebao to icrease silicon steel production capacity

Fujian Kebao, a subsidiary of the Sanbao Group, plans to increase the production of silicon steel grades and tinplate. The Chinese steelmaker is expanding its production of electric steel with a 6-stand, continuous tandem cold rolling mill from Primetals.

Chinese silicon steel producer Fujian Kebao Metal Products, a wholly owned subsidiary of Sanbao Group, has recently placed an order with Primetals for a continuous tandem cold mill (CTCM) including electrics and a full Level 1 and Level 2 automation system at its steel plant in Zhangzhou, Fujian Province. The new mill will be used to produce high-grade silicon steel, supporting Sanbao Group’s goal of becoming a leading provider of high-quality silicon steel and associated services in China.
This CTCM will be designed to achieve stringent thickness and flatness tolerances with high accuracy, Primetals says. The mill stands will be equipped with chamfered shiftable work rolls to optimize the strip edge profile. A multi-channel edge drop thickness gauge is installed after the last stand to minimize edge drop and enhance strip quality.
According to Primetals, the process models will incorporate state-of-the-art solutions, including self-learning neural networks, to ensure high-precision thickness control, optimized edge drop control, and advanced shape control. Highly precise models for edge drop setup and temperature regulation will allow for detailed control of key production parameters.

Expanding in steel product processing

Fujian Kebao Metal Products is leveraging Sanbao Group’s expertise to expand its presence in steel product processing. Sanbao Group operates both LD converter (BOF) facilities and electric arc furnace (EAF) minimill processes, supplying products to a wide range of industries, including ocean engineering, shipbuilding, high-pressure vessels, and the automotive sector.
