Resumo
Slitting processes have been used for many years to increase the productivity of rolling mills, and at the same time to reduce the overall production costs. This technology is used mainly for the production of reinforcing bars, but successful applications exist also for round bar production. Without making major changes on mill layout, multi-slitting process make it possible to produce up to four bars starting from one billet. Danieli Morgårdshammar, world leader in the supply of rolling mills for long products, has been a preeminent provider in slitting technology since its earliest applications. In order to deliver a smooth start-up and increase the reliability of multi- slitting processes, in particular for four-strand slitting, Danieli Morgårdshammar has developed different solutions and improvements to be applied along the mill. Starting from process designing, the Danieli Morgårdshammar package includes a dedicated guide system, loopers, conveyors, alignment devices, water-cooling manifolds and other equipment. Special training and start-up assistance can be provided with the intervention of specialized process, mechanical and automation engineers. This paper will present the modifications that Danieli Morgårdshammar has determined to be necessary to improve multi-slitting processes, and the results of the latest applications realized during the latest mill start-up.
