【摘要】:我國是一個工業(yè)大國,擁有武鋼、首鋼、寶鋼等大型鋼鐵生產(chǎn)基地,雖然我國保持著較高的鋼鐵生產(chǎn)產(chǎn)量,但在鋼材質(zhì)量生產(chǎn)方面,距離世界強國卻有不小的差距。制約我國鋼鐵行業(yè)向前發(fā)展的主要原因是我國鋼鐵設(shè)備普遍老化,自動化程度不高。 在高速軋鋼生產(chǎn)中,其中一個重要的環(huán)節(jié)就是對線材頭尾進行精加工環(huán)節(jié)即飛剪剪切環(huán)節(jié)。 本文設(shè)計了一種新型的飛剪智能控制系統(tǒng)。該系統(tǒng)對飛剪系統(tǒng)進行了優(yōu)化并且應(yīng)用了最新的模糊控制理論,并結(jié)合上最新的西門子PLC產(chǎn)品,能夠有效的提升飛剪生產(chǎn)線的剪切精度。相比復(fù)雜的設(shè)備改造,該系統(tǒng)僅僅通過PLC編程就可以實現(xiàn)模糊控制,改造成本低,最后達到的控制效果滿足實際生產(chǎn)需求。 本文結(jié)合武漢鋼鐵集團公司緊湊式帶鋼生產(chǎn)線改造的實際情況,,對于飛剪剪刃的定位原理進行了分析,對直交流調(diào)速的優(yōu)缺點進行了比較,對于交流調(diào)速裝置和控制方法進行了解析。給出了優(yōu)化的拋物線停車曲線與對階梯型位置環(huán)改造的方案。并且采用新的智能控制算法提高了系統(tǒng)精度。硬件部分用西門子400系列PLC得以實現(xiàn),軟件在STEP7環(huán)境中得以實現(xiàn)。
[Abstract]:China is a large industrial country with large steel production bases such as WISCO, Shougang and Baosteel. Although our country maintains high steel production output, there is not a small gap between China and the world powers in the production of steel quality. The main reason of restricting the development of iron and steel industry in China is that the iron and steel equipment in our country is aging and the automation degree is not high. In the production of high-speed steel rolling, one of the important links is to finish the wire head and tail, that is, flying shear and shearing. A new intelligent control system for flying shear is designed in this paper. The system optimizes the flying shear system and applies the latest fuzzy control theory, combined with the latest Siemens PLC products, which can effectively improve the shear accuracy of the flying shear production line. Compared with the complex equipment transformation, the system can realize fuzzy control only by PLC programming, and the cost is low, and the final control effect can meet the actual production requirements. Combined with the actual situation of the transformation of compact strip production line in Wuhan Iron and Steel Group Company, the positioning principle of flying shear blade is analyzed, and the advantages and disadvantages of direct AC speed regulation are compared. The AC speed regulating device and control method are analyzed. The optimized parabola parking curve and the reconstruction scheme of step position ring are given. And the new intelligent control algorithm is used to improve the precision of the system. The hardware part is realized by Siemens 400 series PLC, and the software is realized in STEP7 environment.
