A Method for Evaluating the Production Energy Efficiency of Steel Rolling System

Abstract

The invention relates to a production energy efficiency assessment method of a steel rolling system. The actual procedure energy consumption value is compared with the standard procedure energy consumption value by calculating the standard procedure energy consumption value and the actual procedure energy consumption value so that the production energy efficiency of procedures of the steel rolling system can be assessed; the standard procedure energy consumption value and the actual procedure energy consumption value are calculated according to the formula that (raw material loaded energy+technology process and auxiliary production energy consumption-recycled and externally-supplied energy-product loaded energy) / acceptable product yield; and the standard procedure energy consumption value is calculated by adopting production technological parameters by reference to a production line. The raw material initial loaded energy and the externally-supplied product loaded energy which are omitted for a long time and are the most valuable are introduced, so that the procedure energy consumption value obtained through calculating is more accurate, objective and real; and standard procedure energy consumption is brought in, and thus, a production procedure or an enterprise low in energy efficiency can be identified easily and improved through the existing technique and corresponding measures on the basis of feasibility and cost efficiency analysis.

Description

technical field [0001] The invention belongs to the technical field of steel rolling production, and in particular relates to a production energy efficiency evaluation method of a steel rolling system. Background technique [0002] In the iron and steel production process, energy costs account for 25% to 30% of the total cost, and my country’s energy consumption per ton of steel is still 10% to 20% behind foreign advanced indicators. It is not only feasible to reduce steel production costs through energy conservation, but also has great potential . However, the existing energy consumption statistics methods, evaluation standards and index systems can no longer meet the needs of iron and steel enterprises for energy conservation and energy management. The index system based on intermediate products (steel) has many disadvantages, and it is difficult to meet the refined management requirements of iron and steel enterprises for energy use. Objective, true and accurate energy s...
