CISDI’s ECIA technology gives strong results at Baowu Zhanjiang

Baowu Group Zhanjiang’s eco-friendly and intelligent new Model C ore yard is now in operation.

CISDI’s patented Eco-friendly Competitive Intelligent Adaptable (ECIA) stockyard technology has upgraded the process layout and stacking-reclaiming match capacity.

Equipment availability has been improved and reclaiming efficiency has been doubled. Maximum stacking capacity is now the largest in China’s steel stockyard industry.

Zhanjiang, China’s first dual-discharge yard, is 90 metres wide and 650 metres long and has been created with two indoor stockpiles to enable a process route which involves two charge lines from the wharf into the yard and four discharge lines from the yard to the downstream users.

A conventional model C yard generally uses an elevated stacker and semi-gantry scraper reclaimer for its one-charge and one-discharge lines. However the scraper reclaimer has become a major restriction on the yard’s equipment availability and efficiency.

CISDI’s one charge and two discharge lines are symmetrically located above the ground of each half of the Model C yard, thus forming totally two charge lines and four discharge lines.

This avoids returns or logistics interruptions and provides effective solutions to the problems of long travel distances for the scraper reclaimer, a limited discharge route from the yard to users, overly frequent changes of stock varieties and overburdened auxiliary equipment.

As a result, in exactly the same site conditions, the yard’s production capacity has doubled.

The designed stacking capacity is 6,250 tonnes an hour and reclaiming capacity is 2,500 tonnes an hour - the largest of its kind in China.

Highly intelligent, the top heavy-duty stacker is supplied with power, water, gas and telecommunication via a long-distance mobile drag chain and the need for manual operation has been eradicated.

Intelligent stacking modes are applied to maximise the yard’s storage volume and to improve the pre-mixing effect.

A China’s first using multi-route semi-gantry scraper caterpillar chains, the reclaimer is a breakthrough for Chinese equipment manufacture and removes the need for importation. The capacity achieved is a record for equipment of its type.
