SIMATIC TDC控制系統(tǒng)在FQM連軋管機(jī)組輥縫控制中的應(yīng)用

Application of SIMATIC TDC Control System to Roll Gap Control of FQM Mill

摘要: 連軋管機(jī)的輥縫控制在無縫鋼管生產(chǎn)中十分關(guān)鍵,它直接關(guān)系到鋼管的幾何尺寸精度,并且影響鋼管的切頭切尾長(zhǎng)度。攀鋼集團(tuán)成都鋼鐵有限責(zé)任公司Ф159 mm FQM連軋管機(jī)組采用世界先進(jìn)的液壓小艙輥縫調(diào)節(jié)技術(shù),電氣控制配置了西門子高端產(chǎn)品——TDC全數(shù)字控制系統(tǒng),通過多種通訊方式的綜合運(yùn)用實(shí)現(xiàn)快速、精確地控制輥縫。重點(diǎn)介紹了TDC系統(tǒng)的組成、通訊方式、軟件編程及應(yīng)用效果等。

Abstract: Being so critical in manufacturing process of seamless steel tubes,the roll gap control of mandrel pipe mill is directly related to the geometric accuracy and crop length of the tube as rolled.The Ф159 mm FQM pipe mill located in Pangang Group Chengdu Iron & Steel Co.,Ltd.is provided with function of quick and accurate control of roll gap owing to being equipped with the hydraulic capsule control(HCC) with the world advanced technological level,the TDC full-digital control system as one of the high-end product by Siemens for the electrical control system which enables comprehensively utilization of multi-communication types for the mill line.The paper focuses on explication of the TDC system,covering such aspects as the composition,the communication types,the software programming and the operation effectiveness.
