Pursuing Environment-friendship , Building Green XINGTAI STEEL
During the on-going reformation, innovation and development, Xingtai Iron & Steel Corp.,Ltd(Xingtai Steel) undertakes the responsibility for the society, endeavors to build up harmonious relationship between the industry and the nature, and implements clean production to achieve Win-Win in Environment and Economy in accordance with the environment protection idea of “input green, output vitality”. The company pays much attention to the environmental protection and sets up a Clean Production Committee with the deputy general manager as the director. The committee includes a particular management department to manage all of the environmental protection work in the company and corresponding management divisions for environmental protection in each secondary department, forming a perfect management system. In addition to optimizing the internal organization, the company establishes and optimizes various regulations including “Air pollution prevention and control management system”, “Water Pollution prevention and Control Management System”, “Solid waste pollution prevention and control management system”, “Noise pollution prevention and control management system”, “Radioactive Sources management system” and so on. Perfect management organization and the rules and regulations laid a foundation for environmental protection work, guaranteed the successful development of the environmental protection work and realized harmonious development between social, economic and environmental benefit.
Xingtai Steel invested heavily to accelerate the environmental treatment; and the company built 151 sets of various environmental protection facilities. The matching rate and relative operation rate achieved 100%. The emissions of dust, flue gas, drainage foul and other pollution factors met the national ultra-low emission standards.
During sintering process, Xingtai steel built up deNOx facility on 198㎡ sintering machine and SDA rotating spray desulphurization to achieve ultra-low emissions. In 2022，the desulfurization and denitrification transformation of 180㎡ sintering machines are finished. The blast furnace, hot air furnace, flue gas treatment, wire rod plant heating furnace desulfurization, low nitrogen transformation, boiler desulfurization transformation are completed in other processes. 77 new dust removal facilities to form perfect dust removal system, and the sintering closed yard to implement yard closing in a greenhouse. In the coking process, we built ten coal storage bunkers and put the coal-hatches closed and transformed to realize a closed storage of process coal, and, environmental protection facilities including coal charging and coke pushing ground station for dust removal, Ammonia decomposition tower, coking water treatment station, coke oven flue gas desulfurization and denitrification and so on were built as supporting facilities. In the steel-making process, the primary and secondary flue gas treatment system of the converter and dedusting and circulating water system of the metal mixer were modified. By the technology of secondary dedusting in converter, the company became the first one which use a converter processed with top suction cover. After completing 3 dedusting modifications in 2017, the problem of red smoke over the factory building was solved completely. In the stainless-steel process, five sets of dedusting facilities to form a perfect dust removal system. In the ironmaking process, the dedusting process was changed from wet dedusting to dry dedusting, thereby dust content in the blast furnace gas was reduced significantly, the quality of the gas was improved and so the dedusting of the gas can be done without water. The flue gas exhausted from the blast furnace iron field and trough region was dedusted and a bag filter system was set up as the supporting facilities. As a result, the flue gas exhausted from the iron field and trough region are treated thoroughly, thereby no red smoke appears upon tapping iron, no dust raises when the material is loaded. In the steel rolling process, walking beam and regenerative reheating furnace which is most advanced in the world are used. With the furnaces, high temperature low oxygen combustion is realized, the life of the Furnace refractories is extended, and nitrogen oxides is reduced. The recycled water meets the quality requirement by replacing belt de-oiling machine with floating oil recovery equipment, a patented product.
In 2011, Xingtai Iron & Steel Corp.,Ltd built a sewage treatment plant to collect the waste water output from all the units which had been treated and met the standard. The waste water was recycled after common treatments such as precipitation, filtration sterilization, etc. and advanced treatments such as ultrafiltration, reverse osmosis and so on.
Xingtai Steel passed the environmental system certification in 2007, set up a perfect institution for environmental monitoring, and equipped various monitoring instruments such as spectrophotometer, photoelectric analytical balance, all-weather atmospheric continuous monitoring system, the hydrostatic balance flue gas concentration detector, sound level meters, precision pH meter, dust concentration detector, atmospheric sampling, carbon monoxide detector. All the posts of the company are monitored daily, weekly, ten days, monthly, quarterly. Control measures are operated for all the environmental protection facilities. Emergency plans were made for all the suspected environmental pollution region. A perfect check-up system was drafted and an on-line monitoring equipment was installed on the wastewater outlet. Surveillance video devices were installed in the steel, iron, coking region to ensure all the pollutants discharging meeting the standard.
In recent years, 153,000 ㎡ of green area, more than 14,000 trees, 30,060,000 bushes and 26,000 ㎡ of turf were added newly in Xingtai steel. The plantable area of the company is 550,000 ㎡, in which 450,000 ㎡ has been planted. The green ratio reached 81.82%. A “garden-like” enterprise is formed, which has flowers in spring, shadow in summer, fruit in autumn and green in winter. Now the flowers looks like brocade, the grass are mattress, sky is blue and water is clear in Xingtai Steel. Blue sky, white cloud, the sunshine and fountains display the modern development of iron and steel enterprises exuberant vigor and vitality of Xingtai Steel.
