【摘要】：鋼鐵行業(yè)是國(guó)家?guī)讉�(gè)支柱產(chǎn)業(yè)之一,其產(chǎn)品種類(lèi)繁多,用途涉及社會(huì)生產(chǎn)生活的各個(gè)方面。社會(huì)經(jīng)濟(jì)的持續(xù)發(fā)展推動(dòng)對(duì)鋼產(chǎn)品的需求量日益增大,也使得整個(gè)行業(yè)需要面對(duì)不斷加劇的市場(chǎng)競(jìng)爭(zhēng)和客戶(hù)提出的日益嚴(yán)格的質(zhì)量要求,因此提高產(chǎn)品質(zhì)量及成品率在各大鋼廠(chǎng)備受關(guān)注。如何實(shí)現(xiàn)對(duì)連鑄板坯質(zhì)量的自動(dòng)評(píng)級(jí)及切割長(zhǎng)度的優(yōu)化是本文著重研究的問(wèn)題。本文根據(jù)鞍鋼鲅魚(yú)圈分公司連鑄車(chē)間實(shí)際生產(chǎn)情況,深入研究連鑄板坯質(zhì)量評(píng)級(jí)及切割優(yōu)化系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)。本文所設(shè)計(jì)系統(tǒng)在功能上分為板坯質(zhì)量自動(dòng)評(píng)級(jí)、切割長(zhǎng)度優(yōu)化兩大板塊,與其對(duì)應(yīng)著兩大處理模型。該系統(tǒng)根據(jù)從一級(jí)PLC系統(tǒng)及三級(jí)MES系統(tǒng)中取得生產(chǎn)數(shù)據(jù),質(zhì)量模型自動(dòng)評(píng)出板坯的質(zhì)量級(jí)別；切割模型根據(jù)鋼水、生產(chǎn)計(jì)劃等信息對(duì)產(chǎn)品切割長(zhǎng)度進(jìn)行優(yōu)化,對(duì)異鋼種混澆加入了自學(xué)習(xí)功能。該系統(tǒng)采用.NET框架下的C++作為開(kāi)發(fā)語(yǔ)言,獨(dú)立設(shè)置一臺(tái)服務(wù)器部署后臺(tái)控制程序,開(kāi)發(fā)基于客戶(hù)端／服務(wù)器模式的窗口應(yīng)用程序并部署在連鑄二級(jí)客戶(hù)機(jī)上；采用Oracle數(shù)據(jù)庫(kù)提供數(shù)據(jù)存儲(chǔ)校驗(yàn)服務(wù)；與一級(jí)通訊通過(guò)西門(mén)子的Simatic Net軟件實(shí)現(xiàn),與MES系統(tǒng)通訊選用IBM的消息隊(duì)列作為數(shù)據(jù)通信中間件；通過(guò)Oracle中的觸發(fā)器從連鑄二級(jí)取得數(shù)據(jù)。系統(tǒng)開(kāi)發(fā)過(guò)程中盡量減小后臺(tái)程序的資源占用,同時(shí)注重前臺(tái)客戶(hù)端功能畫(huà)面的用戶(hù)體驗(yàn)。本文總體結(jié)構(gòu)分為緒論、系統(tǒng)需求分析、系統(tǒng)功能設(shè)計(jì)、系統(tǒng)功能實(shí)現(xiàn)、系統(tǒng)測(cè)試等五個(gè)部分。緒論部分對(duì)系統(tǒng)的選題來(lái)源、目的和意義進(jìn)行了說(shuō)明；需求分析部分對(duì)系統(tǒng)實(shí)現(xiàn)的功能做了全面介紹；功能設(shè)計(jì)部分對(duì)各功能模塊的設(shè)計(jì)、數(shù)據(jù)庫(kù)設(shè)計(jì)、通訊接口設(shè)計(jì)等進(jìn)行了介紹；功能實(shí)現(xiàn)部分詳細(xì)描述了各模塊的具體功能實(shí)現(xiàn)；系統(tǒng)測(cè)試部分詳細(xì)說(shuō)明了系統(tǒng)測(cè)試工作并給出測(cè)試數(shù)據(jù),驗(yàn)證系統(tǒng)功能完整性、高效性及穩(wěn)定性。該系統(tǒng)已在鞍鋼鲅魚(yú)圈分公司連鑄車(chē)間上線(xiàn)運(yùn)行,通過(guò)使用該系統(tǒng)解決了連鑄二級(jí)系統(tǒng)在板坯切割方面存在的問(wèn)題；降低了操作工的勞動(dòng)強(qiáng)度,同時(shí)質(zhì)量評(píng)級(jí)結(jié)果正確率有顯著提高。該系統(tǒng)運(yùn)行穩(wěn)定,可以加入其它功能模塊,也可以廣泛應(yīng)用在其他企業(yè)連鑄車(chē)間內(nèi),具有一定的可移植和擴(kuò)展性。
[Abstract]:Steel industry is one of the pillar industries in our country. The sustained development of social economy promotes the increasing demand for steel products, which also makes the whole industry face the increasing market competition and the increasingly stringent quality requirements of customers. Therefore, the improvement of product quality and product rate in the major steel plants have received much attention. How to realize the automatic grading of slab quality and the optimization of cutting length is an important problem in this paper. According to the actual production situation of continuous casting workshop in Bayuquan branch of Angang, the design and realization of quality rating and cutting optimization system for continuous casting slab are studied in this paper. The system designed in this paper can be divided into two parts: automatic quality rating of slab and optimization of cutting length, corresponding to two processing models. According to the production data obtained from the primary PLC system and the three-level MES system, the quality model automatically evaluates the quality grade of the slab. The cutting model optimizes the cutting length according to the information of molten steel and production plan, and adds the self-learning function to the mixed casting of different kinds of steel. The system uses C in .NET framework as the development language, sets up a server to deploy the backstage control program independently, develops the window application program based on the client / server mode and deploys on the continuous casting secondary client. The Oracle database is used to provide data storage verification service, the communication with the first level is realized through Siemens' Simatic Net software, the message queue of IBM is selected as the data communication middleware, and the data is obtained from the second stage of continuous casting by the trigger in Oracle. In the process of system development, the resource occupation of background program is minimized, and the user experience of foreground client function picture is emphasized. The overall structure of this paper is divided into five parts: introduction, system requirement analysis, system function design, system function realization and system testing. In the introduction part, the source, purpose and significance of the system are explained, and the function of the system is introduced in the requirement analysis part. The function design part introduces the design of each function module, database design, communication interface design and so on, the function realization part describes the specific function realization of each module in detail. In the part of system testing, the system testing work is explained in detail, and the test data are given to verify the functional integrity, efficiency and stability of the system. The system has been running on line in the continuous casting workshop of Bayuquan Branch of Anshan Iron and Steel Co., Ltd., and the problems existing in slab cutting in the secondary system of continuous casting have been solved by using the system. The labor intensity of the operator is reduced and the accuracy of the quality rating results is improved significantly. The system runs stably and can be added to other functional modules and widely used in continuous casting workshops of other enterprises. The system is portable and extensible to a certain extent.
