【摘要】：SGJT公司作为首钢搬迁的主体,努力打造成为具有国际先进水平的精品板材生产基地和自主创新的示范工厂,将冷轧高端精品板材定位为汽车板产品,并通过汽车板的开发带动其他产品的生产及质量管控水平。汽车板生产不仅需要对各工序产生的缺陷进行严格控制,还要求采用一贯质量管理的理念组织生产。前期SGJT公司主要对产品实物质量进行抽检来进行质量判定,这种传统的检验方式与汽车板全过程质量管控的要求相悖,不能满足汽车板不同用户各种差异化的质量需求。本文主要针对汽车板生产过程中表面质量分级判定规则及管理控制展开研究,核心内容分别是表面质量等级及对应关系、表面质量判定规则及其适应性和汽车板过程管理控制业务及信息系统功能的设计。通过确定炼钢、热轧、冷乳各工序的表面质量等级划分及其逻辑关联关系,结合各种缺陷的严重程度建立了汽车板全流程表面质量分级判定规则。在明确各工序质量控制点的基础上,建立了汽车板表面质量的过程管控模式。集判定规则、过程管控业务要求之精髓,设计到信息系统平台中,开发了汽车板表面质量分级判定系统,不仅为家电板、镀锡板等产品的生产及质量管控提供了可靠的规则及信息系统支持,也推动着SGJT汽车板与国内外先进企业接轨,向精品板材基地的目标逐步迈进。对于同行其它类似项目,在理论及实践方法上提供了一定的借鉴作用。本项目实现了炼钢、热乳和冷轧工序全过程的质量管控,实现了全流程的质量检验及分级判定,极大地方便了生产计划排程及产品研发。下一步要坚持"走出去、请进来"的策略,了解各汽车厂对产品不同的质量要求,丰富差异化、个性化的判定规则,并且为满足用户对产品质量的精准了解,需要在实现在线产品质量判定及信息共享方面加快推进力度。
[Abstract]:As the main body of Shougang's relocation, SGJT has made great efforts to become an international advanced production base of fine sheet metal and a demonstration factory of independent innovation. And through the development of automotive plates to promote the production of other products and quality control level. The production of automobile plate not only requires strict control of defects produced by each process, but also requires the concept of consistent quality management to organize production. In the early stage, SGJT mainly carried out spot check to judge the quality of the product. This traditional inspection method is contrary to the requirement of the whole process quality control of the automobile plate, and can not meet the different quality requirements of different users of the automobile plate. In this paper, the classification rules and management control of surface quality in the process of automobile plate production are studied. The core contents are surface quality grade and corresponding relationship. The design of surface quality rule and its adaptability, and the design of automobile board process management and control business and information system function. By determining the classification of surface quality grade and its logical relation in steelmaking, hot rolling and cold milk processes, and combining with the severity of various defects, the classification rule of surface quality classification for the whole process of automobile plate is established. On the basis of defining the quality control points of each working procedure, the process control mode of surface quality of automobile plate is established. Set the rules of decision, the essence of process management and control business requirements, designed in the information system platform, the development of automotive panel surface quality grading system, not only for home appliances, The production and quality control of tinplate and other products provide reliable rules and information system support, but also promote the SGJT automotive plate and advanced enterprises at home and abroad, to the goal of quality plate base step by step. For the peer similar projects, in theory and practice to provide a certain reference. This project realizes the quality control of the whole process of steelmaking, hot emulsion and cold rolling, and realizes the quality inspection and grading of the whole process, which greatly facilitates the production schedule and product development. The next step is to stick to the "go out, please come in" strategy, to understand the different quality requirements of each car factory, rich differentiation, personalized decision rules, and to meet the user's accurate understanding of product quality, Need to achieve online product quality determination and information sharing to speed up the push.
