Shunan Special Equipment Group Co., Ltd. possesses 160+ special products in six categories (e.g. quality alloy steel, die steel, free-cutting steel, high-pressure boiler steel), which have been widely applied in wind power generation, oil field exploration, die moulds and shipbuilding. This project intends to upgrade the existing open-train mill to leading semi-automatic rolling line by plant relocation & revamping so as to allow on-line mass production of high-precision rack steel.

 

■     Short-stress finishing mill, featuring good stiffness and high strength, to produce high-accuracy products, with quick roll change system and high availability.

■     Multiple-length and cut-to-length cutting by a combination of hot shear, hot saw, cold saw and torch cutter, to cater to various requirements.

■     The space for cooling zone after finishing block is foreseen, to allow accurate control of metal temperature and good mechanical property.

■     To cool and level the rack steel by multiple-length zone, and then cut into length, contributing to higher cutting accuracy and rack steel production efficiency.

■     Off-line finishing facilities are installed provided straightening, peeling and pickling treatment.

■     Leading automation control system is installed to ensure reliable operation.

The hot strip mill, the proprietary core equipment of CISDI, is a new generation of mill developed by CISDI especially for premium steel production, featuring high strength, high stiffness and high accuracy.
