Efficiency Optimization Solutions for Metallurgical Processes:
1.Sintering Process – Sintering Gas Cyclic Utilization
By recycling the sintering gas, the double effects of energy saving and gas-processing reduction can be achieved, with energy efficiency improved by 3%~5%.
2.Coking Process
Proper utilization for coking oven gas
Coke oven gas is only used for pre-process of iron production which has low requirement for gas purity, such as sintering, pelletizing and lime kiln. But for the process with higher requirement for fuel gas purity such as hot rolling and cold rolling, cleaner converter gas and/or BF gas is used. By this way, gas cleaning cost is reduced. Meanwhile, because the related processes are adjacent, energy consumption in gas transmission is decreased too.
3.Blast Furnace Process
Energy efficiency is improved by BF top steady-pressure gas recycled into net gas network technology.
4.Steelmaking Continuous Casting Process
Through the package technology, temperature drop is largely reduced, so energy input and consumption is decreased.
5.Steel Rolling Process – Online Heat Treatment after Rolling: Ultra Fast Cooling Process
Through the package technology, temperature drop is largely reduced, so energy input and consumption is decreased.
6.Gas Power Generation
The process of high-temperature ultrahigh pressure gas reheating power generation is taking as an important role for self power generation of whole plant. Steam turbine of Shaangu EKOL, core machine of the power generation, featuring with high-performance single cylinder and single discharge, is designed by Shaangu Europe R&D Center, which improves the generating efficiency by 1~3%.
7.Smart Grid
During actual production, power equipment failure and other factors will lead to the fluctuation of power grid quality. Through power quality management technology and smart grid management platform and terminal, energy saving, consumption reduction, cost reduction and benefits increase of smart grid management can be effectively realized.
