Grinding process

Ground round steel is produced by machining drawn bars. This process allows round steel to be produced with maximum precision in terms of tolerance (up to ISO 6, e.g. h6), roundness and a controlled, homogeneous surface roughness.
The result is an elegant surface with a satin finish.
Another special feature is that a technically crack-free and/or decarburisation-free surface can be achieved through the targeted use of the grinding process.

Areas of application:

  • Automotive industry
  • Machine tools
  • Precision engineering
  • Furniture industry
  • Electrical industry
  • Manufacture of connecting elements

 

Ultrasound testing method

Westfälische Drahtindustrie's bright steel division has its own ultrasound testing system, which is designed for separate <br/> ultrasound testing of round and hexagonal rods.

 


Areas of application

Automated ultrasound testing is used for the non-destructive 100% inspection of internal material defects, as well as for measuring and testing the layer thicknesses of function and safety-critical components.

User industries include the automotive supplier and automotive industry, foundries and manufacturers of containers and semi-finished products.

 


Our ultrasound testing system is designed for the separate testing of round and hexagonal rods.
 

Diameter round rods 8 - 42 mm5/16" - 1.21/32"
Hexagonal rods10 - 36 mm25/64" - 1.27/64"
Bar length2.5 - 6.0 m 
Test speedmax. 2.0 m/sec 
Test sensitivityKSR 0.7 - 1.0 - 1.5 mm possible 

 


Test procedure

Ultrasound testing is used to detect edge defects (longitudinal defects) and core defects in the entire cross section. The coupling of the ultrasound signals takes place using a submersion system,

i.e. during the test, both the test heads as well as the specimens are under water.

Edge defect testing of the round material
The test heads, which are arranged on several levels, are rotated against each other via a central adjustment unit so that the test heads on one level sound exactly into the holes of the next level. This ensures that the test heads do not test redundantly and the edge area is covered 100%.

Edge defect testing of a hexagonal rod
The intromission angle is set centrally to a set

angle for all test heads on a test pad.

Core defect testing on round material
The intromission angle of the test heads is positioned vertically. This ensures that the test heads do not test redundantly, the edge area is covered

100% and the direction-dependent defects are picked up.

Core defect testing of a hexagonal rod
The intromission angle of the test heads is

positioned vertically. The dimension-dependent activation of the test heads and the selection of two aligned positions ensure that the test heads do not test redundantly and that the core area is

covered 100%.
