OREANDA-NEWS. December 21, 2011. Since this year, Baosteel Ltd. has sustained the reduction of energy use cost by lowering the energy consumption of process steps, enhancing the measures of energy cost improvement, further optimizing the process and promoting the energy saving technologies, etc. From January to November, Baosteel Ltd. realized an energy cost improvement benefit of RMB 550 million, accomplishing the annual target in advance.

To further practice the concept of environmental management, and promote energy saving and emission reduction, Baosteel Ltd. takes "strengthening energy control and promoting energy saving and emission reduction" as an important task, establishes "reduction of energy use cost" as the cost improvement project and promotes it as a special project.

With deepening energy cost improvement measure as the center, Baosteel Ltd. streamlined the energy management business comprehensively and implemented energy control by relying on the construction of energy management system. On the basis of Baosteel Ltd. headquarters passing the certification of energy management system, this year, Baosteel Ltd. carried out the promotion and transplant of energy management system projects in Stainless Steel Business Unit and Meishan Steel Company, effectively promoting each unit's enthusiasm in improving energy utilization efficiency and lowering energy use cost.

In the field of energy processing conversion, Baosteel Ltd. takes the improvement of energy processing conversion efficiency as the target, taps the potential of cost reduction and efficiency improvement, and reduces the cost of RMB 82.55 million by optimizing the fuel gas operation mode, etc. The electricity cost is reduced effectively by optimizing the operation mode of generating sets and fuel allotment method to generate more electricity and outsource less electricity.

Optimizing production process and sustaining the energy saving of process steps are still the important approaches by Baosteel Ltd. to drive the improvement of energy cost. With the labor emulation of "saving energy and reducing emission, promoting the improvement of the index of clean production" as the opportunities, the plants and departments directly affiliated to Baosteel Ltd. guide each process step to carry out the pertinent work of energy saving and emission reduction by combining with their own production features. Centering on stable operation of blast furnaces, the iron-making plant carried out many brainstorming tasks such as reasonable control of air blast system. Up to now, the fuel ratio of blast furnace is reduced by 2.5kg/t on a y-o-y basis, creating the lowest record in 20 years. On the basis of increasing the ratio of hot charge and hot delivery in the hot rolling plant, the 1580 line adopted the process energy saving measure of "time for temperature" and the 1880 line promoted "all weather hot delivery", making active contributions to RMB 16.13 million cost reduction in the hot rolling process. The cold rolling plant broke down the energy consumption and use system of the lines, and carried out the benchmarking of like lines, which improved the unit energy consumption control level of the lines effectively. From January to November, the cold rolling process realized a benefit of RMB 41.60 million in energy cost improvement.

This year, Stainless Steel Business Unit and Meishan Steel Company seized the opportunity of certification of energy management system, and strengthened the control over energy efficiency factor through the identification of many energy consumption sources on site, which improved the controllable degree of energy efficiency greatly. Through the implementation of CAL line batch collecting production strategy and optimization of on-line switch-over program of the lines, the stainless steel cold rolling process not only effectively reduces the energy cost of stainless steel cold-rolled products, but also makes active contribution to RMB 64.37 million benefit from energy cost improvement for Stainless Steel Business Unit from January to November. Meishan Steel Company keeps enhancing the energy control measures, and drives the sustained improvement of energy cost. From January to November, RMB 60.30 million energy cost improvement was realized, accomplishing the annual target by 120.6%. The Special Steel Business Unit realized RMB 64.03 million energy cost improvement by increasing the capacity scale and lowering the comprehensive energy consumption per ton of steel, etc.
