Definitions

  • the invention relates to a method for improving adhesion and distribution of a lubricant on the surface of one between two work rolls cold rolled strip made of aluminum or an aluminum alloy, the cold rolled strip for subsequent forming with the Lubricant is coated.
  • strips and sheets are made of aluminum alloys used for the production of body parts, the sheets for example are formed by deep drawing or stretch drawing. to Must carry out these deep-drawing as well as other forming processes Lubricants are used.
  • Lubricants are used.
  • the cold rolled strip is made by the strip manufacturer coated with an oil or a water-soluble dry lubricant and as a pre-assembled strip for deep drawing to the sheet metal worker delivered.
  • the adhesion and distribution properties of dry lubricants on the The belt surface can be applied to the surface by applying a roughness pattern Improve the belt surface significantly.
  • the invention has for its object a method of the aforementioned Type to create, which allows the tape with usual stitch decreases cold rolled.
  • the surface at least one of the work rolls has a roughness pattern consisting of at least there are two intersecting line patterns, these line patterns are each characterized by a plurality of parallel grooves.
  • a roughness pattern is conceivable, which consists of three or more line patterns with parallel grooves.
  • the preferred in practice the roughness pattern consists of two intersecting line patterns.
  • the roughness patterns are preferably chosen so that the distance between adjacent grooves and the depth of the grooves between 0.2 and 2.5 microns, preferably between 0.4 and 1.8 ⁇ m.
  • the distance and depth of the grooves is also called medium roughness.
  • a roughness pattern 10 shown in FIG. 1 on the surface of a not shown Work roll for cold rolling aluminum is composed a plurality of parallel first grooves 12, which form a first line pattern 14, and a plurality of parallel second grooves 16 that form a second line pattern 18 form.
  • the two line patterns 14, 18 intersect at an angle ⁇ that is 90 ° in the present example.
  • the first line pattern 14 forms with the Rolling direction x an angle ⁇
  • the second line pattern 18 an angle ⁇ .lm In the present example, both angles are 45 °.
  • the rolling direction corresponds the circumferential direction of the work rolls.
  • the roughness of the roughness pattern 10 results from the average distance a between adjacent grooves. This distance a essentially corresponds also the depth of the individual grooves.
  • the roughness pattern 10 is on the surface of a work roll in a known manner by grinding the rollers in the two given Grinding directions generated.
  • the resulting average roughness of the Rolling is in the range between 0.4 and 1.8 ⁇ m.
  • the alloy AA 6181 A has been conventionally cast-cast produced ingot hot rolled to a thickness of 4 mm.
  • the Subsequent cold rolling to a final thickness of 1 mm was done with two different ground work rolls.
  • the decrease in thickness of the tape at last cold rolling pass was 45%.
  • the roughness pattern of the work rolls roughened according to the invention corresponded that of Fig. 1.
  • the line patterns formed an angle of each 45 ° to the rolling direction and therefore included an angle of 90 °.
  • the average roughness of the surface of the work rolls was in the range between 0.4 and 1.8 ⁇ m.
  • the roughness pattern used for comparison corresponds to the usual grinding of work rolls today.
  • the rollers are only ground along their circumferential direction, i.e. the roller grinding consists of a variety of parallel across the circumference of the work rolls distributed grooves.
  • the average roughness of the roller surfaces was between 0.4 and 1.8 ⁇ m.
  • the example clearly shows the superiority of surface texturing due to cross-cut rollers compared to the usual texturing due to the simple roller grinding leading to the "Millfinish" surface quality.
