O processo de laminagem é uma parte importante e integrante da indústria transformadora para fornecer chapas e barras de vários tamanhos, calibres e formas. A aquisição e a manutenção de maquinaria tão complexa implicam um grande investimento. O processo de laminagem envolve uma deformação em grande escala do metal. Por este motivo, os rolos recebem uma grande quantidade de carga que é transmitida a outros componentes da máquina. A carga de flexão que incide sobre os rolos é de natureza alternada, provocando a fadiga dos rolos, o que exige uma conceção muito cuidadosa dos rolos para prolongar a sua vida útil. Para calcular a carga exercida sobre os rolos, vários investigadores apresentaram as suas formulações. As formulações de quatro investigadores, ou seja, A. Tselikov, S. Ekelund, W.L. Roberts e E. Siebel, foram analisadas neste livro e a carga dos rolos obtida a partir destas formulações foi comparada com a obtida a partir de uma instalação experimental num laminador. O trem de laminagem estava localizado em M/s B. G. Dhatu Udyog Limited, 52, Industrial Estate, Phase-2, Yamuna Nagar, Haryana (Índia). Verificou-se que os resultados da experiência estavam em boa sintonia com os resultados das formulações teóricas dos investigadores.
