General Layout

Mass flow dynamic simulation and mass flow study of iron & steel enterprises

Analysis and design of mass flow in iron & steel enterprises in the feasibility study, optimization of mass flow solutions, and refinement of the system design.

The dynamic simulation analysis technology has been applied in the mass flow analysis of Zhanjiang iron & steel plant, and in Brazil. This has achieved optimal mass flow design, short process routes, reduced logistics costs and significant economic benefits.

Compact general layout technology for ironmaking and steelmaking workshops

Utilizing the new molten iron transportation technique – “crane + straddle carrier”, the compact layout technology changes the general design of iron and steel workshops. This provides solutions to circumstances when there are no railways or roads available between large blast furnace ironmaking plants and steelmaking workshops.

The compact layout technology is especially suited for small construction sites and projects in places inaccessible by rail.

Currently, it is being applied in several projects including the Chongqing steel relocation project. This resulted in lower energy consumption, less environmental pollution, and optimal land utilization, producing economic and environmental benefits.

Vertical design analysis technology

Digital elevation model using the Bentley landform analysis platform, for 3D terrain analysis on the building site. The vertical design technology uses functions for identification of disadvantageous hydrogeological regions, and rapid comparative analysis of design solutions.
It is ideally suited for the construction of iron & steel plants in mountainous areas or complex terrain. The rapid landform and geological analysis can help optimize the design by making the best use of the hydrogeological conditions and thus reduce construction cost.

Economic evaluation system for greenfield projects

Prepared according to Economic Evaluation Methods and Parameters for Construction Projects (3rd Edition):
Financial Analysis and Economic Evaluation suitable for industrial and non-industrial projects in China.
The above have been successfully applied to the projects such as the feasibility Study for Zhanjiang Iron & Steel plant, and a 10Mt/a Iron & Steel Base in Lianyungang.

Database of steel industry

The information database, serving as a complete, rapid and accurate support for consulting services, has been successfully applied to the projects for which CISDI has provided consulting services.

The consulting results which were validated in the projects have been supplemented into the information database.

Plantwide coordination of process units

  1. Proportioning calculations: For sintering plants, pelletizing plants and blast furnaces according to the ores conditions.
  2. Ramp-up calculations:For coordination between ironmaking & steelmaking plants and preparing the ramp-up curve according to the conditions of the different process units and start-up sequence.
  3. Mass flow system: Overall mass flow diagram prepared with AutoCAD.
