Introduction

Professional interpretation of the guidelines for energy efficiency assessment of continuous color coating process for steel strip

1. Background and significance of standard formulation

With the continuous improvement of energy conservation and emission reduction requirements in the steel industry, GB/T 36023-2018 "Guidelines for Energy Efficiency Assessment of Continuous Color Coating Process for Steel Strip" came into being. This standard aims to provide steel companies with a scientific and standardized energy efficiency assessment method to help companies achieve effective utilization and optimized management of energy in the production process.

Through this standard, companies can accurately evaluate the energy efficiency level of the continuous color coating process for steel strip, identify energy-saving potential, and formulate effective energy-saving measures, thereby reducing production costs and improving market competitiveness.

Standard Framework Dimensions	Specific Contents
Terms and Definitions	Key terms in energy efficiency assessment are clarified, such as benchmark energy consumption, actual energy consumption, energy efficiency index, etc.
Assessment Steps	Carry out in accordance with the provisions of YB/T 4662, including data collection, benchmark energy consumption determination, actual energy consumption calculation and energy efficiency analysis.
Benchmark Energy Consumption	Determine the benchmark energy consumption based on production conditions and process characteristics, and consider the correction of objective factors.
Actual Energy Consumption Calculation	Calculated by the formula (e_in - e_out)/φ, combined with energy consumption data for analysis.

2. Core content of energy efficiency assessment

2.1 Data collection and processing

On-site data collection includes production information, product conditions, energy consumption, ambient temperature, etc. According to 7.1.2, the YB/T 4210 method is used for data collection and processing.

2.2 Scope of energy consumption statistics

The scope of energy consumption statistics for the continuous color coating process of steel strip covers the dedicated water supply system, gas supply system, auxiliary production system, etc., and the energy recovered and supplied to the outside and the life use are clearly deducted.

2.3 Actual case analysis

After a steel enterprise implemented this standard, it optimized the heating process and adopted energy-saving materials, and its energy efficiency index dropped from 1.2 to 0.95, reaching the industry-leading level.

3. Implementation Suggestions

3.1 Improve Energy Management Level

Enterprises should scientifically equip energy metering instruments in accordance with the requirements of GB/T 21368 and GB17167 to ensure the accuracy and completeness of data.

3.2 Optimize Production Process

Reduce the energy consumption of curing furnaces by improving process parameters such as coating technology, heating form and gas type. For example, changing from indirect heating to direct heating can reduce the energy consumption of curing furnaces by 30%.

3.3 Promote Energy-Saving Technology

Use waste heat efficient recovery technology, variable frequency speed regulation technology and big data analysis technology to monitor and optimize energy consumption in the production process in real time. At the same time, promote the use of power-saving equipment such as permanent magnet speed regulation motors.

4. Future evolution of the standard

With increasingly stringent environmental protection requirements and technological advances, GB/T 36023-2018 will be continuously updated to adapt to new energy efficiency assessment needs. It is recommended that enterprises continue to pay attention to standard dynamics and adjust energy efficiency management strategies in a timely manner.

Summary

GB/T 36023-2018 provides a scientific methodology for energy efficiency assessment of continuous color coating process of steel strip, and helps enterprises identify and implement effective energy-saving measures through standardized data collection and analysis processes. It is recommended that enterprises combine their own characteristics in actual applications and flexibly apply the various provisions in the standard to achieve the best energy efficiency improvement effect.
