A device for the mechanical cleaning of wire rods for the production of drawn metallic wires includes a pair of elements supported by a shaft, each element having a truncated-conical body and a flat disk that closes the truncated-conical body, defining an internal annular space that contains the steel wool. The flat disk has openings that are shaped as a slot. The two elements being disposed one in front of the other, with a space between the two flat disks. During operation, by rapid rotation of the shaft, the steel wool expands under the effect of a centrifugal force in radial direction, thus creating an axial thrust component on the steel wool such that the steel wool escapes partially and elastically from the openings of the flat disks so that the steel wool brushes against the surface of the wire rod in transit in the space between the two elements.

A method for preparing a multilayer metal composite pipe includes steps of: internally and externally grinding blank pipes; cleaning oil stains; assembling a multilayer metal pipe; drawing to reduce a diameter; performing high-speed friction welding at the pipe ends; performing heat treatment; performing four-roller cross-rolling; straightening; performing two-roller cold-rolling; performing cold-drawing to reduce the diameter; performing cold-expansion to reduce the diameter; performing precise cold-rolling; degreasing; brightening; performing surface grinding; cleaning dust; detecting multilayer metal interface bonding; detecting flaws; testing metal structure performance; and sizing and packaging. By cycling the cold-drawing, the cold-expansion, and the precision cold-rolling, key indicators such as product dimensional accuracy, surface quality, material properties, and crystal grain size can be collaboratively controlled, so as to achieve higher accuracy, better performance, and more outstanding extreme specifications. The present invention solves the problem of inconsistent extension due to differences in metal properties.

A method of cleaning can bodies having a continuous sidewall closed at one end by an integral bottom portion opposite an open end is described. A can body transporter is populated a plurality of can bodies. The transporter transfers can bodies through a can body washer apparatus from an entry end to a delivery end. A plurality of spray bars are located between the entry end and the delivery end and delivers a washing solution to the plurality of can bodies. A substantially constant can body population density is maintained on the can body transporter by controlling a speed of the can body transporter relative to a rate of production of can bodies produced by an upstream can body making apparatus. A time duration of an exposure of the plurality of can bodies to the solution is controlled by regulating delivery of the solution.

A high efficiency stripper nozzle, with a through hole configured to be connected to the through hole of another nozzle, guide, or nozzle, which comprises several radial channels that pass through the nozzle from the perimeter zone to the hole at its entrance zone. The nozzle may be divided into several pieces which can be connected together in a removable way and replaceable, which may form the radial channels between them with different sections and angles with respect to the axis of the hole. The radial channels may contact externally with an opening located on one of the surfaces of the nozzle or on one of the surfaces of the nozzle to which the nozzle is connected.
