In principle, investors of EAF-steelmaking project should check carefully whether there are enough prerequisite conditions, then make a thoughtful plan of the project. Following five crucial factors should be primarily reviewed:
1.Product positioning
Product positioning mainly includes product kinds, specifications and product quantity. It is difficult for a steel plant to produce all kinds of steel.?Therefore?the product position is the core of project design. Firstly, it should be suitable for the enterprise’s own conditions and production process characteristics. Secondly, adjusting product structure will cause changes in process flow and production layout, resulting in low utilization rate of production equipment or disruption of production order and finally affect production efficiency. Thus EAF steelmaking projects should determine different production processes and equipment combinations based on requirement of different product structures and quality, as well as corresponding subsequent construction. In general, the process configuration of stainless steel production is: EAF+AOD+LF; The technological configuration combination of bearing steel is: EAF+LF+VD; Common carbon steel and alloy structural steel production configuration combination is: EAF+LF. In the actual production, a good configuration plan is in line with the enterprise’s own conditions, meanwhile it must meet technological requirements of the production.
2.Project capital
EAF steelmaking project funds include construction funds and production preparation funds. A highly efficient and smooth EAF steelmaking production line is to need the stable supply of raw materials and energy media, a?complete?process equipment, completed auxiliary facilities and orderly production operation.?It should avoid using outdated equipment on production?lines, that will bring more adverse results to the enterprise such as low production efficiency and unstable product quality troubles, etc.
3.External conditions
Electric arc furnace steelmaking production is a complicated process course. Supply of energy, electricity and raw materials of the plant should be adequate, the product had good demand and marketing channels; regional logistics and transportation is?convenient, and?the government policy is favorable?to the local?industry, etc.?If the above external conditions are not ideal, and there are no corresponding remedial measures, it will have a very adverse impact on the project construction and production operation, which should be treated seriously and made prudent decisions.
4.Design and construction
The ideal plant has correct design of the production line, right selection of process equipment and reasonable configuration of public facilities. Some plants spend a lot of money repairing and transforming unreasonable production lines which there is defection on design and layout, but the end result is not always ideal.?Therefore,?the process design and construction scheme should be repeatedly deliberated and demonstrated before?the construction.?Ensure that the process design and construction plan is advanced and reasonable and suitable for the enterprise’s own conditions.
5.Engineering team
The EAF project involves many majors such as metallurgical technology, machinery, electric power, water supply and drainage, hydraulic pressure, environmental protection and civil engineering, etc., which require multiple majors to cooperate in operation and construction. Thus?this?project engineering should be undertook and completed by a professional team with rich experiences and strong competent.
