Danieli Cartridges for Rolling Mill of Changzhou Dongfang Steel
Changzhou Dongfang Special Steel has contracted Danieli for a rolling mill upgrade consisting of a full set of cartridges for its 16-stand bar mill in Jiangsu Province in China. The project carried out by Danieli Service China led to improved product quality, reaching the standard GB/T 702-2017 grade 2 for the entire product range, and higher efficiency thanks to fewer mill stoppages. Furthermore, the design and the quality of the Danieli cartridges supplied allows easy maintenance and lower maintenance costs.
In 2013 Danieli supplied Changzhou Dongfang Special Steel a section mill featuring cartridge rolling stands, which is in full operation.
The intervention is part of the transformation and upgrading with the strategy of “quality development, green development and safety development” of Changzhou Dongfang Special Steel, which produces in excess of 3 million tonnes per year steel long products. Carbon steel, high-pressure boiler pipe steel, spring steel, bearing steel, grinding ball steel, gear steel, and light rail steel are some of the grades produced there.
