Abstract
"MODOS OPERACIONAIS COMBINADOS E TIPOS DE ARMAçõES EM LAMINADORES TANDEM A FRIO". A invenção refere-se a um processo para modos operacionais combinados de distintas armações de cilindros em um laminador tandem a frio, abrangendo respectivamente um par de cilindros de trabalho (10) e cilindros de apoio (12) em armações de 4 cilindros e, adicionalmente, um par de cilindros intermediários (11) em armações de 6 cilindros, sendo que ao menos os cilindros de trabalho (10) e os cilindros intermediários (11) cooperam com dispositivos para deslocamento axial, caracterizado por combinação das diversas tecnologias: emprego da tecnologia CVC/CVC¬ plus¬ com contornos de cilindro CVC de ordem superior, sendo que cada cilindro de trabalho/intermediário (10, 11) possui uma superfície alongada pelo curso de deslocamento; emprego da tecnologia Per Cross (PC), sendo que cada cilindro de trabalho/intermediário (10, 11) pode ser pivotado paralelamente ao plano da tira; emprego do deslocamento, orientado a aresta de tira, dos cilindros de trabalho/intermediários (10, 11) , sendo que cada cilindro de trabalho/intermediário (10, 11) possui uma superfície alongada pelo curso de deslocamento com um polimento cilíndrico ou abaulado e são deslocados entre si relativamente à posição de deslocamento neutra (S~ zw~ = 0 ou S~ aw~ = 0) no meio da armação (Y-Y) simetricamente respectivamente na mesma medida na direção de seu eixo de rotação (X-X) ; e caracterizado ainda pelo fato de que com uma correspondente concepção de instalação com apenas um conjunto de cilindros geometricamente igual pode ser realização a tecnologia CVC/CVC¬ plus¬ bem como a tecnologia do deslocamento orientado a aresta de tira bem como eventualmente a tecnologia PC."COMBINED OPERATING MODES AND TYPES OF FRAMES IN COLD TANDEM LAMINATORS". The invention relates to a process for combined operating modes of different cylinder frames in a cold tandem rolling mill, respectively comprising a pair of working cylinders (10) and support rollers (12) in 4-cylinder frames and additionally , a pair of intermediate cylinders (11) in 6-cylinder frames, with at least working cylinders (10) and intermediate cylinders (11) cooperating with axial displacement devices, characterized by a combination of various technologies: use of technology CVC / CVC¬ plus¬ with higher order CVC cylinder contours, with each working / intermediate cylinder (10, 11) having an elongated surface by the travel stroke; Per Cross (PC) technology, whereby each work / intermediate cylinder (10, 11) can be pivoted parallel to the plane of the strip; the edge-oriented travel of the work / intermediate rollers (10, 11), with each work / intermediate roll (10, 11) having a surface elongated by the travel stroke with a cylindrical or bulged polish and are offset from each other relative to the neutral displacement position (S ~ zw ~ = 0 or S ~ aw ~ = 0) in the middle of the frame (YY) symmetrically respectively to the same extent in the direction of its axis of rotation (XX); It is further characterized by the fact that with a corresponding installation design with only a geometrically equal set of cylinders can be realized the CVC / CVC¬ plus¬ technology as well as the technology of the strip oriented orientation as well as the PC technology.
