摘要： Contact strips are obtained by segmenting a secondary strip of contacts fabricated from a metal ribbon in which openings are formed with an original regular pitch to form a discontinuous central strip of blades. Each blade is twisted to produce a primary contact strip. The method further includes pleating the primary strip and a hardening heat treatment, and begins with the following operations: the ribbon is metal-plated on both sides to cover at least the central strip with a layer of a metal that is a good electrical conductor, openings are formed in the ribbon, and each blade is twisted. It then includes the following successive operations: the primary strip is pleated, the hardening heat treatment is then applied to produce the secondary contact strip, and the secondary strip is segmented into a plurality of contact strips.

摘要： The invention is directed to a process for the production of hot-rolled steel strip from continuously cast precursor strip in at least two deformation stages, each deformation stage having one or more roll stands, wherein initial rolling is carried out in the first deformation stage at the output speed at which the precursor strip exits from the continuous casting plant and the intermediate strip thus produced is coiled prior to the second deformation stage at the output speed at which it exits from the first deformation stage, wherein the coil is uncoiled after reaching the coil weight and is supplied to the second deformation stage for finish rolling at the initial roll pass speed and is then coiled in the desired finished coil sizes. In the first deformation stage, at least 40 tons of a casting sequence of the continuous casting plant is rolled out in endless manner to form intermediate strip and is coiled to form an intermediate coil without severing, and after more or less endless finish rolling the intermediate strip of this intermediate coil is severed according to the desired coil weights and coiled as finished strip only following the second deformation stage.
