【摘要】：钢铁工业从节能化、清洁化生产到循环经济模式,是近年来钢铁工业高速发展的必然结果,是社会进步和实现生态平衡的必然要求。社会的发展和行业竞争的加剧,低成本策略是企业求生存、求发展的有效之策。钢铁工业是能源消耗大户,统计表明,国内钢铁行业的能耗占全国总能耗的10%以上,因此推广节能减排技术已成为保证我国钢铁工业可持续发展的关键。转炉炼钢在当代钢铁生产中依然占据主导地位,我国转炉钢比例已超过90%,负能炼钢是炼钢节能的主要技术,转炉炼钢厂生产实现负能炼钢具有降低成本、减少污染、实现能源再循环等技术优势,国内外转炉炼钢厂均把实现转炉负能炼钢作为提高经济效益和环境保护的重大工艺技术进行研究。在追求产品质量和效益的今天,钢铁厂实践循环经济,负能炼钢是必然选择。推广负能炼钢对实现节能减排目标,保证钢铁工业健康发展具有十分重要的意义。转炉炼钢已不再是纯粹的耗能工序,也是回收二次能源的主要工序,实现负能炼钢是衡量一个炼钢厂先进技术水平和管理水平的重要指标。本文主要介绍为降低转炉炼钢工序能耗实现转炉负能炼钢,研究包括转炉煤气回收技术、蒸气回收技术以及氧气、电力、煤气等能源介质的相应节能降耗等技术措施,在转炉炼钢实际生产过程中通过设备改造、优化工艺操作、新工艺技术推广应用等主要有效手段的实施推广,从而达到了有效降低炼钢工序能耗的目的。本课题的开展大大推动了西钢负能炼钢的技术进步,并在付诸实践中形成一套完整的生产和管理制度,最终,西钢炼钢厂转炉工序在实现负能炼钢基础上,工序能耗达到-5.91kgce/t(1kgce/t=29.26GJ/t),取得了显著的经济效益、环境效益和社会效益。
[Abstract]:The iron and steel industry from energy-saving, cleaner production to the recycling economy model, is the iron and steel industry in recent years, the inevitable result of rapid development. It is the inevitable requirement of social progress and ecological balance, the development of society and the aggravation of industry competition. Low cost strategy is the effective strategy for enterprises to survive and develop. Iron and steel industry is a large consumer of energy consumption, statistics show. The energy consumption of domestic steel industry accounts for more than 10% of the total energy consumption in China. Therefore, the promotion of energy saving and emission reduction technology has become the key to ensure the sustainable development of China's iron and steel industry. Converter steelmaking still occupies a leading position in the contemporary steel production, the proportion of converter steel in China has exceeded 90%. Negative energy steelmaking is the main technology of energy saving in steelmaking. Converter steelmaking has the advantages of reducing cost, reducing pollution and realizing energy recycling. Converter steelmaking plants at home and abroad take the realization of converter negative energy steelmaking as a major technology to improve economic efficiency and environmental protection. In pursuit of product quality and efficiency today, the steel plant practices circular economy. Negative energy steelmaking is an inevitable choice. It is very important to promote negative energy steelmaking to achieve the goal of energy saving and emission reduction and to ensure the healthy development of iron and steel industry. Converter steelmaking is no longer a pure energy consumption process. It is also the main process of recovering secondary energy. The realization of negative energy steelmaking is an important index to measure the advanced technology level and management level of a steelmaking plant. This paper mainly introduces the realization of converter negative energy steelmaking in order to reduce the energy consumption of converter steelmaking process, including converter gas recovery technology. Steam recovery technology and energy medium such as oxygen, electric power, gas and other technical measures, such as energy saving and consumption reduction, in the actual production process of converter steelmaking through the transformation of equipment, optimization of process operation. The main effective means such as the popularization and application of new technology and so on have achieved the goal of effectively reducing the energy consumption of steelmaking process. The development of this subject has greatly promoted the technical progress of negative energy steelmaking in XISCO. And form a set of complete production and management system in practice. Finally, the converter process of XISCO steelmaking plant is based on the realization of negative energy steelmaking. The process energy consumption is -5.91 kg / t ~ (-1) kg / t ~ (29.26) GJ / t ~ (-1), which has achieved remarkable economic, environmental and social benefits.
