【摘要】：冷軋硅鋼板廣泛應(yīng)用于中小型電機(jī)、發(fā)電機(jī)和家用電器等的制造,橫向厚度差是冷軋硅鋼產(chǎn)品的重要質(zhì)量指標(biāo)。硅鋼板的橫向厚度差直接影響到疊片后電機(jī)芯層的性能,甚至整個(gè)電機(jī)的發(fā)熱和效率。冷軋硅鋼板橫向厚度差的產(chǎn)生主要來(lái)源于熱軋來(lái)料的板凸度和冷軋帶鋼的邊部減薄(Edge Drop)兩方面。熱軋階段現(xiàn)有軋鋼設(shè)備基本可以滿足對(duì)板凸度要求,于是冷軋硅鋼板橫向厚度差就主要由冷軋時(shí)帶鋼的邊部減薄所決定。本文以鞍鋼股份有限公司冷軋硅鋼廠(簡(jiǎn)稱A鋼廠)五機(jī)架UCM六輥軋機(jī)為研究對(duì)象,指出UCM軋機(jī)在軋制無(wú)取向硅鋼時(shí)邊部減薄控制方面的不足,通過分析和研究邊部減薄產(chǎn)生機(jī)理,確定UCM六輥軋機(jī)冷軋帶鋼過程中產(chǎn)生邊部減薄的影響因素。本文結(jié)合Pro/E與ANSYS Workbench兩種軟件的特點(diǎn),通過三維軟件Pro/E對(duì)UCM軋機(jī)輥系-帶鋼進(jìn)行了實(shí)體建模,并將實(shí)體模型導(dǎo)入ANSYS Workbench軟件中建立有限元模型,通過對(duì)軋制力、彎輥力和竄輥位置等因素發(fā)生變化后對(duì)邊部減薄產(chǎn)生影響進(jìn)行具體分析,得出上述因素變化時(shí)邊部減薄所對(duì)應(yīng)變化規(guī)律。為解決現(xiàn)有UCM六輥軋機(jī)在生產(chǎn)無(wú)取向硅鋼產(chǎn)品時(shí)邊部減薄嚴(yán)重的問題,A鋼廠對(duì)原有UCM軋機(jī)進(jìn)行改造,通過增加工作輥竄輥裝置和工作輥采用EVC輥形來(lái)提高UCM軋機(jī)對(duì)邊部減薄的控制能力,本文通過現(xiàn)場(chǎng)實(shí)物板形對(duì)比,現(xiàn)場(chǎng)隨機(jī)抽取樣品測(cè)量來(lái)比較技術(shù)改造前后UCM軋機(jī)在邊部減薄控制方面的提高。
[Abstract]:Cold rolled silicon steel plate is widely used in the manufacture of small and medium electric machines, generators and household appliances. The difference of transverse thickness is an important quality index of cold rolled silicon steel products. The transverse thickness difference of silicon steel directly affects the performance of motor core layer after lamination, and even the heat and efficiency of the whole motor. The transverse thickness difference of cold rolled silicon steel mainly comes from two aspects: strip crown of hot rolling and edge thinning (Edge Drop) of cold rolled strip. The existing rolling equipment in hot rolling stage can basically meet the requirements of plate crown, so the lateral thickness difference of cold rolled silicon steel plate is mainly determined by the edge thinning of the strip during cold rolling. This paper takes the five-stand UCM six-high rolling mill in Angang Cold rolled Silicon Steel Plant (referred to as A Steel Plant) as the research object, and points out the deficiency of the UCM mill in the control of edge thinning when rolling non-oriented silicon steel. By analyzing and studying the mechanism of edge thinning, the influence factors of edge thinning in the cold rolling process of UCM six-high mill are determined. According to the characteristics of Pro/E and ANSYS Workbench software, the solid model of UCM rolling mill roll system and strip steel is modeled by 3D software Pro/E, and the solid model is introduced into ANSYS Workbench software to establish the finite element model, and the rolling force is analyzed. After the change of roll bending force and roll position, the influence of edge thinning is analyzed in detail, and the corresponding change law of edge thinning is obtained when the above factors change. In order to solve the serious problem of edge thinning in the production of non-oriented silicon steel by existing UCM six-high mill, the original UCM mill was reformed in A steel plant. By adding the work roll channeling device and the work roll adopting EVC roll shape to improve the control ability of the UCM mill's edge thinning, this paper makes a comparison of the actual shape of the work roll on the spot. In order to compare the improvement of edge thinning control of UCM mill before and after technical modification, random sampling samples were taken in the field.
