Digital Stamping Machines
For durable incision coding on continuous caster and rolling mill products.
Rail-/Beam Stampin Stamps up to 3 characters per second
Temperature up to 1200 degrees centigrade
Characters size from 3 mm to 80 mm
Good legibility on rough and graded surfaces
For numeric, alpha-numeric and customized characters
Stamping of coded information onto steel surfaces allows tracking of single items and avoids mixing up of different items.
Stangl Technik offers a new generation of improved stamping machines for the special requirements of the steel industry.
The installation is working at the end of the outrun roller table or after a movable or ducking stop at any place.
Each chisel is exactly guided and lubricated. Each stamping movement (chisel stroke) can be precisely controlled. The body of the chisel and the stamping tool are two separate parts. The result is shorter stamping time, improved legibility and reduction of wear part costs.
The linear layout of the chisels allows the coexistence of digital lettering and customized letters (e. g. Arabic or Latin characters) without change of tooling or software.
Rail/Beam Stamping Machines
For durable incision coding of continously moving long products.
Beam speed up to 8m/sec.
Temperatures from 400 to 1000 degree Celsius
Adjustable penetration depth from 0.1 to 1 mm
Maximum 25 characters
Character height is between 5 and 16 mm.
Character change in 0.6 sec.
These machines are designed for continuous, fully automated incision marking of long steel products on the fly. They meet the AREA- and UIC-regulations for railway rails.
With diskhead stamping machines it is possible to stamp railway rails or beams or girders at the end or continuously with preselected distance over the total length.
The installation is working in rolling mills after the last roller stand or in front or after the shearing line.
The on-coming rail on the roller table is detected with an infrared sensor (giving the length position on the roller table).
The stamping head (stamping disc) moves with a high acceleration and sufficient speed to the position of the rail-web on the roller table. As soon as the stamping head is correctly adjusted above the web and the rail is coming to the stamping location (pre-selected distance from the beginning of the rail), the stamping head accelerates to the actual rail speed and is lowered into the web of the rail. Now the circumference of the stamping disk marks/rolls the combination of characters (numbers and letters) into the web of the rail with pre- selected pressing force.
After this procedure the stamping head is lifted out and above the rail web. The stamping head stops revolving and the machine waits until the rail is coming to the next stamping location. If necessary the wheel-magazine in the disc-stamping head changes one character (letter) within 0,8 sec. during this waiting time.
As soon as all pre-selected stamps are rolled into the web of the rail, the stamping head is lifted to the highest position and the cross-slide of the stamping machine moves the stamping head to the waiting position. The stamping machine is waiting for the next on-coming rail.
In case a different combination of numbers and letters is required for the next rail, the outside magazine changes the characters according to that during the waiting time between the two rails.
All information is shown on a monitor. Data-input and data exchange is possible via computer link to main computer or (in case of a problem with the connection) manually with a keyboard.
Paint Marking Systems
For automated paint marking of continously moving long products
Product speed up to 10 m/sec
Industrial-strength printing systems (IP class 67)
Product temperature up to 1100 degrees centigrade
character sizes up to 150 mm
multiple print heads
Marking of rolling mill products differs from the usual requirements in the packaging industry. The markings must be legible from a great distance, white, heat resistant, and printed at high speed. Furthermore the printer is exposed to harsh environmental conditions.
Nowadays, newly developed, extremely heat resistant paints are available and it is possible to mark steel ingots with a surface temperature up to 1100 degree centigrade without changing of the white colour.
Depending on your specification we will use our own ink-jet head or embed industrial-strength ink-jet systems by other manufacturers into the facility. These printer heads are of robust design with a high protection class and have a self cleaning function. Each print head is charged with internal air pressure in order to ensure additional protection against dust particles. The ink inside the system is permanently being re-processed to avoid any irregularities.
Powder and Wire Marking Systems
For marking the surface of hot steel products with a mixture of metallic powder smelting in a gas flame.
For Slabs, Blooms and Billets
Write all alpha-numeric numbers and letters
Product temperature up to 1200 degrees centrigrade
Character height of 30mm - 150mm
Marking Layer Thickness of 10 – 100 µm
This technology uses a powder mixture of Aluminium oxide and Aluminium. Therefore we can provide heat resistant letters and numbers on hot surfaces. In order to meld the boundaries of the metal grains the powder is blown though a flame. This technology makes it possible to operate independent of the block temperature. Aluminium ensures the bonding to the steel surface, whilst Aluminium oxide provides the legibility even at highest temperatures. His system is designed to produce an extremely clear, sharp and legible mark, at a very low running cost. The marks do not disappear, even after the re-heating furnace or extended periods of outside storage.
Mould Powder Feeder
Suitable for the automatically feeding of granulated casting powder into the mould of a slab casting machine
Frequency-controlled powder feeding via spiral
Feeding rate between 0.8 and 8 kg/min
Adjustable distribution speed of 50 mm/sec
Speed of conveying spiral 10 to 280 rpm
For granulated and non granulated powder
The conveying system of the granulated mould powder is by means of air or nitrogen with parallel boosters, giving a very slow conveying speed (1 - 2 m/s) so there is no necessity to start with empty transportation tubes. The feeding rate (kg powder/ton steel) is continuously adjustable and the quantity of granulated powder is synchronised with the casting speed of the continuous caster. Data-input is from the host computer or can be fed in manually. The mould powder feeder distributes the 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. This ensures that in the unlikely event of a serious malfunction, where extensive repairs need to be carried out, the feeder can be removed from the site so as not to obstruct normal operations.
New Automatic Inline Rotary Deburrer
For slabs, blooms and billets
Product Temperature up to 1200°C
Fully automated deburring of front and rear side without stopping of the product
Low maintenance expenses and high system stability by use of standard modules
Speed of roller table up to 0.5 m/sec
The standardised machine is designed for removing of torch cutting burrs.
Continuous cast products (billets, blooms, slabs) are machined in a running through working process. The active principle of the Rotary Deburrer is based on a rotating barrel equipped with hammer plates. Enforced through the centrifugal force the hammers knock off the burrs from the running slabs, blooms or billets. A hydraulic driven vertical shifting slide lifts and lowers the “hammer mill”. This method is suitable for the most steel grades and brings advantages for the further process. The product edges will be flattened, damage to roller-tables minimized and therefore the life time of rolling tools will increase.
Ladle Shroud Manipulator
Designed for easy and safe operation of the ladle shroud tube between working position (ladle nozzle), oxygen cleaning, disposal position and magazine position.
3 different operation modes (manual, semi automated, fully automated)
Manipulator arm consisting of 3 easy changeable main parts
Adjustable smooth movement and soft connection process
Adjustable connection force between shroud tube and ladle nozzle
Safety equipment against bursting tubes
Remaining pressure in case of hydraulic and electric break down during casting
Parallel valve to disconnect the shroud in emergency cases
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. Up to now two models of ladle shroud manipulators have shown good results: Manipulators which stand on a column and are mounted on the casting platform, close to the ladle revolving turret. This machinery type is especially suitable as a supplementary manipulator for existing plants, because in most cases the space available on the tundish car is not sufficient for a trouble free assemblage. Manipulators which are directly mounted on the tundish car. This type offers certain advantages as to dimension, length of overhang and room requirement, as the whole unit can be built more compactly because of its small distance from the ladle slide. The method of operation of both manipulators is basically the same.
