Benefits of technology

This technology uses an improved version of this type of machine called Cooling Device (CWD). It allows for precise control over how much liquid or gas flows through specific parts inside the roller's housing during processing without wasting too many materials on account of its design. By controllably changing the amount of fluid flow within certain areas along one side of the rollers, the size of these zones changes, allowing for more effective heat transfer from the material being processed. Overall, this innovation helps reduce energy usage by producing better-quality rolled products with consistently high temperatures throughout their entire length range.

Problems solved by technology

This patented technical solution described in the patents relates to improving the coolability of rollings produced with special alloys called bismuth martonitride or carburum manganite while reducing manufacturing costs associated with the installation of expensive external devices like edge heaters.

Abstract

The invention discloses a lower spraying and cooling device arranged between finishing mill frames. The lower spraying and cooling device is arranged below strip steel on the inlet side of the finishing mill frame, and comprises a collecting pipe which is arranged along the direction vertical to the running direction of strip steel, a water inlet pipe arranged on the collecting pipe, a plurality of discharging and spraying pipes, and a plurality of plunger devices; the plurality of discharging and spraying pipes are uniformly distributed above the collecting pipe along the axial direction of the collecting pipe; each row of the discharging and spraying pipes comprises a plurality of spraying pipes which are distributed along the radial direction of the collecting pipe, and each spraying pipe is communicated with the collecting pipe through a lower port; and the plurality of plunger devices correspond to the plurality of discharging and spraying pipes. Each plunger device comprises a plunger pipe with one sealed tail end, and a plunger which is arranged in the plunger pipe; the plunger pipe is provided with holes which are communicated with the spraying pipe and a water inlet whichis communicated with the collecting pipe; and the plunger can slide along the axial direction of the plunger pipe so as to block the water inlet.
