Lenzing Technik’s marking systems division is one of the worlds’ few suppliers of steel marking technology.

Placing their products in-line with the consecutive stages of the steel mill process, Lenzing Technik Steel Marking Systems produces marking machinery employing heat resistant paint, metal alloy powder and brute force to apply a permanent mark on the steel industry’s offerings such as hot coils, plates and rails as well as equipment for ladle shroud manipulation.

Similar technologies are present on your desk, you may notice with amazement. Ink jet printers for presentations are a small scale equivalent to Paint Marking Systems, while those long gone daisy wheel printers of the 1970s have grown up and become Disc Head Stamping Machines.

Situated in Upper Austria, a region known for it’s perennial metallurgical tradition and innovative powers resulting in the invention of such elementary steel production procedures like LD (Linz-Donawitz), Lenzing Technik’s Steel Marking Division offers a product range employing a vast variety of different marking methods.

Lenzing Technik Steel Marking Systems is part of Lenzing Technik, a subsidiary company of the world’s largest viscose fibre producer. Lenzing Technik has grown from an engineering division solely operating in the chemical industry into a multi-discipline engineering enterprise supplying variate engineering services.

Lenzing Technik Steel Marking Systems’ competitors include such well-known brands as Numtec-Interstahl GmbH, Green Project S.r.l., UTEC GmbH, Magnemag A/S and IMS S.r.l.

Recently, the company announced another successful customer site run of their coil paint marking system redesigned earlier last year. Rapidly expanding their product line beyond conventional offerings is seen as a major key to success in the steel marking market.

This commitment being further supported by a plethora of improvements and enhancements to their existing product range, Lenzing Technik Steel Marking Systems’ division manager Kurt Stangl reliantly emphasises:

We feel highly prepared for challenges to come! Our customers honor the work we do, our recurring endeavours to expand the limits and the services we offer.

Products of Lenzing Technik Steel Marking Systems

Paint Marking Systems

Extremely heat resistant paints are used to mark steel ingots with a surface temperature up to 1100 °C without any alteration of the white colour.

Paint marking excels stamping or powder marking in marking speed, having it’s maximum at 10 m/s (depending on the character size).

Continuously adjustable character sizes and automated nozzle cleaning reduce operating cost.

Powder Marking

Powder Marking Machines mark the surface of hot steel products (slabs, blooms, billets) with a mixture of metallic powder smelting in a gas flame “pen”.

The powder combines with the hot steel and congeals immediately.
Result: A permanent marking image, unsusceptible to abrasion and resistant for storage.

Beam Stamping Machine

The automated marking of moving long products like railway rails, beams or girders is usually the task of a diskhead stamping machine.

Products are stamped either at the end or in recurring distances.
Employing a character size of 16 mm and penetration depths from 0.1 to 1.0 mm AREA and UIC regulations are fulfilled.

Digital Stamping Machine

The Digital Stamping Machine stamps characters using seven or sixteen straight chisels. In the same way as a pocket calculator displays all numbers and a limited number of letters, the DSM can mark all characters by a suitable combination of lines.

Each chisel is driven by a hydraulic piston. Character sizes of up to 40 mm and high penetration ensures good legibility of text even with steel grades of 900 N/mm² tensile strength.

Ladle Shroud Manipulator

Ladle shrouds are highly fire-proof tubes for connecting the ladle with the tundish.
These tubes are moved manually, by means of an appropriate device or, in larger continuous casting plants, by means of a manipulator.

Mould Powder Feeder

The mould powder feeder distributes powder uniformly on top of the liquid steel, thus improving the surface quality of the product.

The feeding arms and nozzles are small enough to allow visual control and manual access to the steel bath in the mould. Units are installed on a car with the possibility to lift and remove the powder feeders manually.
