CISDI heads back to Baowu Zhanjiang Steel after major contract win

CISDI has won a major contract with Baowu Zhanjiang Steel.

The company is to design the plant’s BF3-centred system – incorporating a stockyard, blast furnace, continuous casting and hot strip mill.

In addition, CISDI will design a plant-wide power supply and distribution system, water supply and drainage, a laboratory, the general layout and transport system.

Zhanjiang Steel’s Phase I has been running for two years with BF1 and 2-centred plants and the development of Phase II began at the end of 2018.

The new stockyard will be designed for receiving and supply, yard proper, crushing and screening, blending and proportioning. It will have a PCI centralised supply system to downstream blast furnace, plus auxiliary and supportive facilities.

By Phase II, the stockyard’s annual receiving capacity will be 43.86 million tonnes (dry basis), of which the BF3-centred plant will require 11.31 million tonnes.

Its annual blending capacity will be 16.32 million tonnes (dry basis), of which the BF3-centred plant requires 5.62 million tonnes.

Its annual supply capacity will be 71 million tonnes, with BF3-centred plants requiring 20 million tonnes.

To build this fully-equipped stockyard to fit the demands of the 10-million-tonne coastal steelworks, which has multiple-users and complicated supply routes, CISDI is applying its highly-advanced intelligent and eco-friendly stockyard expertise.

Green and clean production methods will be encompassed, along with digital management and unmanned autonomous operations.

Blast furnace 3 will be built to a volume of 5,050 cubic metres, matching BF1 and 2. The annual hot metal output will be 4.02 million tonnes.

Phase I’s twin blast furnaces are seen as 21^st century models of eco-friendlier innovation.

They each have excellent running indicators and are achieving sound environmental results for low energy use and material consumption, recycling and zero waste discharge. They were package-supplied by CISDI and feature a high degree of CISDI’s innovative technical features.

The new continuous casting plant will be built as a 2-strand 1,650mm slab caster capable of producing 2.80 million tonnes a year.

Phase I operates with a pair of 2-strand,  2,150mm slab casters  and a 2-strand, 2,300mm slab caster 4.

CISDI undertook the design of the caster shop plant and a full package supply for caster 4. It carried out most of the package supply for casters 1 and 2.

Thanks to a number of CISDI’s self-developed innovative technologies, Phase I’s casters have been running continuously and very efficiently and are able to produce 8.50 million tonnes of stable, high-quality slabs a year. They are used for rolling automobile sheets, high-strength steel coils and other high-end products. Baowu Zhanjiang have found them to be remarkably cost-efficient and making a healthy profit.

The hot mill will feature a new 1,780mm strip production line consisting of a reheating furnace, reversible roughing mill, crop flying shears, finishing mill, downcoilers and a coil dividing and skin pass mill. The new hot strip line will be designed to produce 4.50 million tonnes of coils a year.
