1、論文題目：硅錳爐配方管理與配料控制系統(tǒng)研究專業(yè)：測試計(jì)量技術(shù)及儀器研究生：邢樂（簽名）指導(dǎo)教師：張傳偉（簽名）摘要隨著經(jīng)濟(jì)的發(fā)展，鋼鐵行業(yè)對硅錳合金需求量也隨之增大，但我國鐵合金行業(yè)配料系統(tǒng)的自動化程度均較低。針對這種現(xiàn)狀，論文研究一種配方管理和硅錳爐配料控制系統(tǒng)，達(dá)到生產(chǎn)過程自動化、提高配料精度，增強(qiáng)人機(jī)交互能力，減輕工人勞動強(qiáng)度的目的。論文先是針對配方計(jì)算和配料系統(tǒng)發(fā)展趨勢進(jìn)行論述，分析硅錳合金冶煉生產(chǎn)工藝流程，設(shè)計(jì)配方計(jì)算與配料控

2、制系統(tǒng)的總體方案。根據(jù)硅錳爐配方計(jì)算現(xiàn)狀，結(jié)合硅錳爐配方計(jì)算方法，基于VB設(shè)計(jì)配方管理系統(tǒng)，實(shí)現(xiàn)配方的自動計(jì)算及數(shù)據(jù)管理功能。對配料誤差產(chǎn)生原因進(jìn)行分析，為了提高系統(tǒng)的控制精度，提出模糊PID控制算法，利用MATLAB軟件中的模糊控制工具箱設(shè)計(jì)模糊PID控制器，在Simulink平臺下搭建仿真系統(tǒng)，驗(yàn)證模糊PID控制的可行性。通過分析硅錳爐實(shí)際生產(chǎn)中的配料工藝，設(shè)計(jì)硬件系統(tǒng)，采用工控機(jī)和PLC相結(jié)合的總體控制結(jié)構(gòu)，使配料控制系統(tǒng)實(shí)現(xiàn)稱量

3、、配料的自動化。最后，采用VisualBasic和Access數(shù)據(jù)庫進(jìn)行配料系統(tǒng)軟件設(shè)計(jì)，實(shí)現(xiàn)配料系統(tǒng)的配方管理、數(shù)據(jù)管理、配料監(jiān)控和數(shù)據(jù)輸出等功能。關(guān)鍵詞：硅錳爐、配方管理、配料控制、VB、模糊PID控制研究類型：應(yīng)用研究Subject:DesignoftherecipemanagementbatchingcontrolsystemfSubmergedArcFurnaceSpecialty:MeasurementTechnologyI
