【摘要】：鋼鐵工業從節能化、清潔化生產到循環經濟模式,是近年來鋼鐵工業高速發展的必然結果,是社會進步和實現生態平衡的必然要求。社會的發展和行業競爭的加劇,低成本策略是企業求生存、求發展的有效之策。鋼鐵工業是能源消耗大戶,統計表明,國內鋼鐵行業的能耗占全國總能耗的10%以上,因此推廣節能減排技術已成為保證我國鋼鐵工業可持續發展的關鍵。轉爐煉鋼在當代鋼鐵生產中依然占據主導地位,我國轉爐鋼比例已超過90%,負能煉鋼是煉鋼節能的主要技術,轉爐煉鋼廠生產實現負能煉鋼具有降低成本、減少污染、實現能源再循環等技術優勢,國內外轉爐煉鋼廠均把實現轉爐負能煉鋼作為提高經濟效益和環境保護的重大工藝技術進行研究。在追求產品質量和效益的今天,鋼鐵廠實踐循環經濟,負能煉鋼是必然選擇。推廣負能煉鋼對實現節能減排目標,保證鋼鐵工業健康發展具有十分重要的意義。轉爐煉鋼已不再是純粹的耗能工序,也是回收二次能源的主要工序,實現負能煉鋼是衡量一個煉鋼廠先進技術水平和管理水平的重要指標。本文主要介紹為降低轉爐煉鋼工序能耗實現轉爐負能煉鋼,研究包括轉爐煤氣回收技術、蒸氣回收技術以及氧氣、電力、煤氣等能源介質的相應節能降耗等技術措施,在轉爐煉鋼實際生產過程中通過設備改造、優化工藝操作、新工藝技術推廣應用等主要有效手段的實施推廣,從而達到了有效降低煉鋼工序能耗的目的。本課題的開展大大推動了西鋼負能煉鋼的技術進步,并在付諸實踐中形成一套完整的生產和管理制度,最終,西鋼煉鋼廠轉爐工序在實現負能煉鋼基礎上,工序能耗達到-5.91kgce/t(1kgce/t=29.26GJ/t),取得了顯著的經濟效益、環境效益和社會效益。
[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.
