Baowu Group’s Qingshan Steel plant has put its rebuilt stockyard through a trial production, by charging the raw materials into the ironmaking plant.

CISDI’s eco-friendly and intelligent ECIA model C stockyard has been applied and stockpile’s maximum cross section has been expanded to 1,000 square metres without changing the yard’s 90-metre span or its height.

Maximising stockpile improves both the yard’s storage capacity and cost savings per tonne of ores.

The top eco-friendly stacker uses long-distance drag chains for its power, water and gas supplies and for its communications.

Innovative use of an air cable supplies compressed air to the stacker. This solves numerous problems encountered by having an air compressor onboard the stacker, such as a high fault rate, unstable operations and high operational cost. It also enables the air-mist dust suppression device to run more stably and efficiently.

The stacking belt conveyor is optimised for its remainder recovery technology and reduced the cost.

Qingshan Steel’s stockyard rebuild applies CISDI-patented autonomous process selection, digital stockyard and unmanned stacker-reclaimer expertise.

It will enable intelligent operations management and the Pocket Factory for the foreseeable future.

An intelligent centralised stockyard control centre is now on the agenda, which will co-ordinate with WISCO’s intelligent centralised control centre for ironmaking and upstream procedures.
