The upgrade of Laiwu Steel’s stockyard is proceeding well under CISDI’s expert guidance.

Laiwu Steel, located in China’s Jinan Province, was founded in 1970.

China’s largest production base for H sections, gear steel and powder metallurgy, its annual production capacity is 10 million tonnes.

CISDI has successfully hot-tested a new dual-conveyor charging system for the blending and proportioning yard at the steelworks.

Previously, two sintering machines (each 265m²) were operating with only one belt conveyor for charging. This had seriously impeded sintering and downstream production for a considerable period of time.

Laiwu Steel needed the belt conveyor rebuilding and also required the rebuild of its blending and proportioning system. 

Taking into account charging inadequacy and process layout deficiencies, CISDI’s innovative proposal was to build a dual-belt conveyor system, which would greatly increase charging capacity, and to install new blending and proportioning bins at stockpile 3.

The new conveyor applies membrane structures which enable production demand to be met effectively. In addition, the span has been reduced, which has created a more stable structure.

The upstream and downstream systems of the new bins are made from five membrane structures and cover an area of nearly 300,000 square metres.
