Primetals Technologies to supply continuous galvanizing and pickling line to Chengde Steel

Chinese steel maker Chengde Steel Vanadium Titanium cold-rolled sheets Co, Ltd. (Chengde Steel) has placed an order with Primetals Technologies to supply a continuous pickling line (CPL) and a continuous galvanizing line (CGL) for a new cold rolling and processing plant to be built in the company´s location in Chengde, Hebei Province.

The CPL is designed to process one million tons of cold strip per year, while the CGL will handle 410,000 tons per year. Both lines are able to be operated with strip of high thicknesses. The processed strip will be used for the building, construction and automotive markets. The production of the first galvanized coil and the first pickled coil is planned for the third quarter of 2019.

Chengde Steel is part of the HBIS Group Co., Ltd., China´s largest steel producer with an annual production of over 46 million metric tons in 2016. The new cold rolling complex in Shuangluan District, Chengde City is designed for an overall output of 2.1. million tons per year, including cold-rolled coils, annealed coils, full hard coils as well as hot galvanized coils. Primetals Technologies is responsible for the engineering and supply of the mechanical and electrical equipment of the CGL and the CPL.

The equipment supplied for the CGL will also include a skin pass mill with a roll force of up to 1,200 tons and a tension leveler. The line is able to process hot strip with thicknesses between one and six millimeters as well as cold strip with thicknesses ranging from 0.5 to 2.5 millimeters at a maximum strip width of 1,630 millimeters. The CPL will come with a side trimmer, a scrap chopper and a skin pass mill with a maximum roll force of 1,500 tons. Strip thicknesses from one to eight millimeters may be processed, also at widths of up to 1,630 millimeters.

Primetals Technologies also is responsible for the engineering, supply, installation and commissioning supervision of the electrical and automation systems. These include low voltage systems, motors, VVVR drives, motor control centers (MCCs), measuring equipment as well as the basic (level 1) and process automation (level 2). An interface with a future level 3 system will also be prepared. Chengde Steel will provide the medium voltage systems, transformers with switch gear, and will be responsible for the installation.
