Abstract

ROLO CONVEXO PARA INFLUENCIAR O PERFIL E A PLANURA DE UMA TIRA DE LAMINAÇÃO Uma grande diferença de diâmetro dos rolos intermediários (20, 21) em armações de laminação de seis rolos com retífica x3 provocava elevado desgaste e superfície ásperas nos rolos de apoio (30, 31), sendo que a imagem de danos nos rolos de apoio (30, 31) depois de um tempo de uso mais longo correspondia à forma da retífica CVC. Também em armações de quatro rolos era necessária a amplitude de retífica inicialmente igualmente nitidamente maior do que para os programas laminados, de modo que se estabelecia também aqui a desfavorável imagem de desgaste nos rolos de apoio. Para minimizar esses erros, de acordo com a invenção se propõe que o comprimento de superfície de rolo (L) de cada rolo intermediário (20, 21) em uma armação de laminação de seis rolos ou cada rolo de trabalho (15, 16) em uma armação de laminação de quatro rolos se compõe de um segmento de superfície de rolo (z) cilíndrico e de um segmento de superfície de rolo [R(x)] curvo convexo, sendo que o ponto de transição (A) do segmento de superfície de rolo cilíndrico para curvo é selecionável na faixa L/2 < = x < L, e o contorno curvo, que se estende em ambos os rolos (20, 21) respectivamente para lados contrapostos por uma parte 25 da largura de material de laminação na direção da extremidade da superfície, é descrito por uma polinômio matemático R(x) = a0 + . . . anxn com n > = 5.
