4 Basic principles

The energy efficiency assessment of the refining process outside the furnace should follow the following basic principles.

a) Legal compliance principle. the assessment object should conform to national laws and regulations, meet the requirements of the steel industry policy, and comply with relevant energy conservation and emission reduction.

System standard requirements;

b) Efficient energy use principle. Promote efficient use and rational allocation of energy, and encourage enterprises to adopt advanced energy-saving technologies or management measures.

Improve low-energy production links;

c) Highlight key principles. Focus on key processes and equipment with high energy consumption and high energy saving potential, and focus on energy efficiency.

major factor;

d) Scientific and reasonable principles. the impact of incomparable factors should be removed within the scope of the conditions, and the comparability and evaluation of the evaluation indicators should be guaranteed.

The rationality of price analysis.

5 Evaluation steps

The energy efficiency evaluation of the refining process outside the furnace includes but is not limited to the following steps.

a) determine the statistical range of boundaries and energy consumption;

b) collecting the field data of the evaluation object and calculating the actual energy consumption;
