OREANDA-NEWS. May 17, 2011. The BDCD(Breakdown mill of CISDI)1350 Housing was successfully set up on the jobsite of the large-sized profiled-bar production line of Handan Iron & Steel Works, marking a formal commencement of the installation works for the rolling mill. This facility was independently developed by CISDI Engineering Co., Ltd. (CISDI), and was manufactured by CISDI Heavy Industry, one of the CISDI’s subsidiaries, reported the press-centre of MCC.

The complex production line for heavy rail and large-sized profiled-bar in the existing area of Handan Steel Works was designed by CISDI. The BD1 and BD2 breakdown mills, which were the core parts of the main rolling line, was supplied as a whole by CISDI. These two devices are the largest breakdown mills in China, with the maximum roller diameter of Ф1350mm, the roller length of 2300mm and a net height of 8445mm. Through these facilities, large-sized rectangle blank, shaped blank and round blank could be manufactured.

In the past time, all the breakdown mills on the heavy rail production lines were monopolized by foreign manufacturers. Now such monopolization has been successfully broken by CISDI after tough competition and contract winning on the BD1 and BD2 breakdown mills. Up to now, CISDI has developed four kinds of breakdown mills, of which three kinds (six sets in total) have been sold on the market.

The successful setting up of the BDCD1350 Housing is the achievement made by CISDI in terms of its core equipment development strategy and the design principle of “Standardization, Seriation, Modularization and Elaboration”. It also symbolizes that the BDCD breakdown mill of CISDI with proprietary intellectual property rights has taken a leading position in the field of long rolled steel in China.
