Definitions
- the invention relates to a method for separating Steel slabs under Use a high pressure water cutter.
- JP 09108800 A in a thin metal sheet produced by continuous casting first or to introduce several longitudinally extending grooves, which the Reduce the metal sheet thickness accordingly at these points and then the metal sheet along these grooves a high pressure water jet, to which an abrasive powder is added is to cut through before the metal sheet strips then obtained be wrapped cold.
- the slabs processed in the context of the present invention can have a thickness of 20 cm to 25 cm.
- the liquid metal is poured into a water-cooled mold, from which the solidified part continues during casting in the form of blocks, bars, bars, billets, tubes or cylinders is led away.
- the strand leaving the mold passes through a cooling zone in which the strand is sprayed with water, whereby a solidification also occurs inside the strand.
- Driving rollers guide the strand to a separator that according to the invention is arranged relatively close to the outflow nozzle and is a water jet separator.
- the temperature of the Continuous material in the separation area is around 700 ° C.
- the water pressure used in cutting is at least 3 x 10 8 Pa (3000 bar), but is preferably above it, in particular it is up to 7 x 10 8 Pa (7000 bar).
- the water jet has a jet diameter of 25 ⁇ m to 0.4 mm and a nozzle exit speed between 300 and 1200 m / s.
- abrasive agent to the water or other liquid jet or chemicals are added which have a separating effect increase or increase.
- the device used according to the invention essentially consists from an electric motor, which is a hydraulic pump operates, which in turn the liquid medium a high pressure booster supplies. Usually used as a liquid Water is expelled through a nozzle under high pressure has the smallest possible outlet opening in diameter.
