【摘要】：国内首钢、宝钢、武钢和鞍钢等油耗管控措施是比较完备的,且降油耗效果显著;本钢总公司和汽车制造厂商也对成本影响最大的油耗项目进行管控、立项和攻关,并制定了改进措施。因此,本论文决心加强本钢矿业油耗管控,对油耗管控风险影响因素进行风险识别、风险评估、风险改进和风险监控,优化和改进工艺过程,以大幅降低矿业油耗。通过对目前常用的风险分析方法进行比较并选择,在考虑本钢矿业油耗管控范围比较大、管控措施比较繁杂、降油耗要求的幅度大、二期油耗管控信息化项目需求分析不到位等的前提下,进行风险管理:风险规划、风险识别、风险评价、风险应对和风险监控。本文在对大量文献、实践、经验调研的基础上,对油耗管控进行系统地、全面地和深入地分析和研究,其完成的工作主要包括以下四个方面:(1)通过充分运用头脑风暴法和六顶思考帽查找到风险因素,采用因果图(5M1E)进行因素分解,识别出32个末端影响因素。(2)应用风险矩阵对风险因素分析以查找出风险要因,识别出16个风险影响因素;按照FMEA规则进行分析,按RPN值进行风险排序,确定了14个关键、重要因素,如:发动机空转、弯道较多、天气不好等。(3)应用SWOT分析、决策树法进行风险应对分析;制定出本钢矿业油耗管控风险应对对策表,因地制宜地制定出油耗管控措施,并采用关键风险指标管理。(4)以提高链箅机作业率和提高球团矿抗压强度及合格率案例进行分析,实例验证了所提风险管理模式的有效性。通过油耗指标不断下降的阶段数据对比,表明:本钢矿业油耗管控的风险管理模式具有现实可操作性、有效性、系统性和有针对性,这对制造业风险管理应用具有指导意义。
[Abstract]:Domestic Shougang, Baosteel, WISCO and Angang are relatively complete in fuel consumption control measures, and the effect of fuel consumption reduction is remarkable. Benxi Iron and Steel Corporation and automobile manufacturers also control, set up and solve key problems of fuel consumption projects with the greatest cost impact, and formulate improvement measures. Therefore, this paper is determined to strengthen the management and control of fuel consumption in Benxi Iron and Steel Co., Ltd., to identify the risk factors of fuel consumption control, risk assessment, risk improvement and risk monitoring, and to optimize and improve the process in order to greatly reduce the fuel consumption of mining industry. Through the comparison and selection of the risk analysis methods commonly used at present, it is considered that the scope of control and control of fuel consumption in Benxi Iron and Steel Co., Ltd is relatively large, the control measures are more complicated, and the requirements for reducing fuel consumption are large. Under the premise that the demand analysis of the second phase fuel consumption control information project is not in place, the risk management is carried out: risk planning, risk identification, risk assessment, risk response and risk monitoring. On the basis of a large number of literature, practice and experience investigation, this paper makes a systematic, comprehensive and in-depth analysis and research on the management and control of fuel consumption. The work completed mainly includes the following four aspects: (1) the risk factors are found by making full use of brainstorming method and six thinking caps, and the factor decomposition is carried out by using causality diagram (5M1E). 32 terminal influencing factors were identified. (2) the risk factors were analyzed by using risk matrix to find out the risk factors, and 16 risk influencing factors were identified. According to the FMEA rule, the risk is sorted according to the RPN value, and 14 key and important factors are determined, such as: engine idling, more bends, bad weather and so on. (3) SWOT analysis and decision tree method are used to analyze the risk response. Draw up the countermeasures to deal with the risk of fuel consumption control and control in Benxi Iron and Steel Co., Ltd., and formulate the measures to control and control fuel consumption according to local conditions. The key risk index management is adopted. (4) the cases of improving the working rate of grate machine and improving the compressive strength and qualified rate of pellets are analyzed, and the effectiveness of the proposed risk management model is verified by an example. Through the comparison of the stage data of the declining fuel consumption index, it is shown that the risk management mode of mining fuel consumption control in Benxi Iron and Steel Co., Ltd. has practical maneuverability, effectiveness, systematicness and pertinence, which is of guiding significance to the application of manufacturing risk management.
