Operator from ECR has to verify that plates is in center for shear to work properly. Needed a good visible laser line on dark plates. Laser length up to 20mtrs. Z-laser designed the next generation green laser with high output power. Visible on dark surfaces with limited impact from ambient light conditions
Alignment for Cut to Length: Positioning lasers
Pilger mill in tube rolling mills - hot and cold pipe detection
Higher production quality and throughput
- Positioning laser visible on plates/ sheet increasing operator efficiency
- Faster and more precise alignment of the shears, band saws and miter saws
- Laser length available upto 30mtrs depending upon mounting height
- Visible laser colour like green and red
Laser mounted with help of precision mounting bracket
Challenges
- Operator from ECR has to verify that plates is in center for shear to work properly
- Needed a good visible laser line on dark plates
- Laser length up to 20mtrs
- 24vdc supply and works in an industrial environment
Green laser visible to the operator
Solution
- Z-laser designed the next generation green laser with high output power
- Visible on dark surfaces with limited impact from ambient light conditions
- High IP protection class against dust and moisture
- Sturdiness to withstand impact and vibrations
- Accessories like precision mounting bracket and climate case
Other application areas
Red laser is continuously projected onto the Laser installed with installation height of 200
cutting edge of the saw so the production to max 1000mm to distribute the light homogenously
engineer can align the workpiece with precision over the entire distance.

Challenge
- The increasing flexibility of production lines requires a high adaptability of sensors. Continually changing object geometries, different temperatures and very high radiation or surrounding temperatures are no rarity.
- In a pilger mill those rough conditions can be found, among others in the production of seemless steel pipes. The raw steel blocks, each weighing a few tons are heated up first in a round oven at a temperature of 1300 °C.
- After descaling of the surface, the steel block is prepunched in a hole press with a strength from a converted 2000 t. In the next sloping rolling mill the growing pipe rotates between two rollers that are positioned at an angle to each other. The punching is widened to the size of the mandrel diameter.

Solution
- The sensor that was installed at this application is the HMD OKA 2038.38 G with tube OL 19.
- The signal of the infrared sensors controls the movement of centering device and abutment. The point of view is restricted by the tube and prevents disturbances by steam in the cooling phase.
- An optimum adaptation to the operating conditions is given due to the adjustable response temperature. The HMD with self-learning response temperature (Auto-Teach function) is suited to continually changing conditions.
- The compact sensor with a stainless steel housing can withstand surrounding temperatures of up to 75° C. The use of a cooling jacket raises this up to 200° C.
- Alternatively sensors with fibre optic cables are available which permit an application at ambient temperatures up to 600° C without cooling.
Customer Benefits
- Maintenance-free
- High temperature stability
- Recognition of hot objects at big distances
- Self adjustment with Auto-Teach or step switch for the response temperature
