„Please do not touch“ – Vacuum protects the good side

New vacuum technology guarantees high surface quality.

"Please do not touch" - Vacuum protects the good side

Georg: The lower side of the strip is sucked against the braking roll by vacuum

At the Aluminium 2018 show in Düsseldorf, GEORG presented its new vacuum braking roll for slitting lines for the first time to the public. The new roll was developed specifically for strips that have to meet extremely exacting surface quality requirements. While coming with a new energy-saving vacuum technology, the new roll enables high strip speeds and optimizes the recoiling of difficult-to-process strips.

In slitting lines, braking units arranged ahead of the recoiler are often fitted with rollers, felt pads or belts which are pressed against the strip from below and above. However, especially when slitting strip for applications that demand surfaces of highest quality, these methods entail the risk of leaving marks on the „good side“ of the strip. Moreover, the felt pads are subject to intensive wear and have to be replaced at short intervals. All this impairs the productivity of the line.

At the trade show, GEORG presented its advanced vacuum braking unit, which achieves the braking effect by sucking the lower side of the strip against the braking roll. The upper strip side remains completely untouched, ruling out any risk of damage by mechanical components.

One of the innovative features of the unit is the possibility of setting the angle of aperture around the circumference of the roll within wide ranges: Depending on the wrap angle, the aperture may cover between 60 and 180 degrees of the roll circumference, allowing the strip tension to be flexibly adjusted to the specifics of the strip processed. Together with the high-precision regulation of the vacuum pressure, the roll thus achieves optimal recoiling with varying strip types and under varying conditions.

Additionally, only those sectors of the roll length covered by strip will be activated. In this way, GEORG achieves a dramatically lower energy consumption than conventional vacuum-based braking systems.

GEORG has developed the vacuum system specially for strip thicknesses between 0.08 and 0.8 mm. It is suitable for all customary widths of cold rolled aluminium strip. GEORG is currently manufacturing a slitting line with the new technology for an aluminium producer in Asia. The line will be designed for up to 2,150 mm wide strip.

The slitting line will pro process slit coils in widths between 15 and 2,140 mm and outside diameters of up to 2,800 mm. The slitting line has been specifically designed to recoil the slit strip at speeds of up to 600 m/min. A transfer car guides the individual slit strips automatically to the recoiler. This solution makes for smooth transfer and threading of the slit strips, and extremely short coil-to-coil times.

Antonio Garcia, Head of GEORG“s Finishing Lines Division, explains where his customers can save costs: „With the newly developed vacuum technology, our customers achieve tangible savings on energy and they can expand the range of strips processable in their slitting units. Also the maintenance effort is much lower compared to other systems because the braking system contains no parts subject to wear.“

The vacuum equipment will be installed below the shop-floor level in a sound-proof compartment next to the looping pit, so that the noise produced by the equipment is hardly heard on the shop floor.

Nozzles speed up pickling

Pickling of carbon steel strip: New process increases pickling speed and/or reduces length of pickling lines

Nozzles speed up pickling

Assembly of a spray module at the pickling line entry; the pickling tanks are in the background.

At Metec, CMI UVK will introduce its newly developed spray modules for pickling steel strip. In these modules, the acidic pickling liquor removes the scale much more efficiently from the strip surface than in conventional turbulence pickling lines. Thus, carbon steel strip can now be pickled in markedly less time than before, and newly built pickling lines can be designed with a shorter length. Moreover, it will be possible to flexibly adapt the pickling parameters from coil to coil. As a further advantage, the process saves energy because the pickling liquor temperature can be lower.

The new, patent-pending technology consists of several nozzles arranged across the width of the strip. These nozzles spray the acid onto the strip surface from above and below with high impact. Alone by the impinging acid jet is a large part of the scale adhering to the strip removed.

Compared to conventional turbulence pickling, spray pickling achieves an equivalent surface quality in much less time. In laboratory tests, the pickling time, for example for „1.1231“ was reduced from 55 to 14 s, for „1.8159“ from 39 to 18 s and for IF steel from 33 to 10 s.

By combining spray pickling modules and pickling tanks in a specific way, this process opens up numerous new possibilities. The options range from the installation of just one spray module at the line entry through to a layout with several cascades of spray pickling modules and pickling tanks arranged in series. In all cases, the surface quality will be equal to or even better than that achieved in conventional turbulence pickling lines.

The length of newly built pickling lines can be reduced from more than 80 m – the typical length of conventional turbulence pickling lines – down to below 50 m. In other words, a 40 percent length reduction. This would cut the investment costs for a typical-size pickling line by several hundred thousand euros.

If the modernization target is to maximize the capacity while retaining the existing line length, the strip speed may be increased from, let“s say, 180 m/min to about 300 m/min through spray pickling.

With spray pickling, it is now also possible to vary the pressure of the frequency-controlled circulation pumps within wide ranges. This enables the pickling line to be set to optimal conditions for different steel grades in a very short time – even from one coil to the next.

The new process also makes it possible to pickle at lower temperatures than in the past, with the positive effect of saving costs on energy. Lowering the liquor temperature, for example from 90° C to 70° C, can save more than 20 percent of the energy costs.

AlumGreen reduces the cost of corrosion protection by 30 percent

Coating with aluminium is significantly more cost-effective than galvanising

AlumGreen reduces the cost of corrosion protection by 30 percent

Cross section of the coating furnace

At the Wire AlumGreen presents – for the first time in the world – the completely new process for coating cold drawn steel products with aluminium. With this process a more homogeneous and durable coating is achieved than by galvanising. Not only that: production costs are reduced radically and natural resources are protected at the same time.

AlumGreen has developed a unique process for corrosion protection of cold drawn steel products using aluminium. The process is ready for normal industrial application and is the first of its type in the world. The company is presenting at Wire – a premiere for the trade – the first ever 12-strand plant for steel wire. This is currently being built to the order of a Russian customer at Zink Körner in Hagen (Germany).

Aluminium coatings are superior to zinc coatings with respect to their corrosion resistance by a high factor. Consequently this new process provides the most durable corrosion protection currently available today on the market.

The AlumGreen process is based on a completely new approach. A corrosion protection layer is added to the wire as it is led through a closed coating chamber filled with molten aluminium. As the wire runs through the coating plant continuously, there is no limit to the length of the wire to be coated.

Better protection at a significantly lower cost

Aluminium yields for a lower coating thickness a protective effect several hundred percent more effective than that for zinc. Consequently the AlumGreen process reduces significantly both purchasing and production costs. The most important factor is that the material costs for aluminium are only around a third of those for zinc. Initial investigations reveal that the overall production cost is 30 % lower than for galvanising.

AlumGreen will present at Wire the first coated wire samples. In the future the company will extend applications of the process to products like steel strip, narrow tubes and reinforcing steel.

Compatibility with the environment and sustainability

As a result of the reduced metal usage, lower transport costs and no fluxing agents or harmful chlorides at all, the effect of the AlumGreen process on natural resources is much less than for galvanising plant.

Another major advantage: AlumGreen is very much a process for the future. Whereas the known reserves of zinc will only last another 21 years, it is predicted that those for aluminium will be sufficient for more than 200 years.

Fluidized-bed technology gaining ground

Resource-saving heat treatment of wire: Already two furnaces of this technology in the commissioning phase

Fluidized-bed technology gaining ground

The new-generation fluidized-bed furnaces have no distributor pipes or tiles.

The new fluidized-bed furnaces for the heat treatment of wire, which Wire Körner presented for the first time at Wire 2010, have convinced wire producers: The first two plants of this kind will be operational before Wire 2012 opens its doors. These innovative furnaces, which have no distributor pipes or tiles, afford the benefit of lower energy consumption by up to 15 percent and low investment and maintenance costs. Additionally, premixing of the combustion gas outside the furnace guarantees uniform temperature distribution and reduced emissions.

The first two orders were placed right after Wire Körner had introduced the new fluidized-bed furnace at Wire in 2010. The first furnace is currently being commissioned at a customer“s site in Turkey. The second one is being installed in Ecuador. At Wire 2012, Wire Körner will present first reports on practical experience with this new technology.

The patent-pending furnaces dispense with distributor elements as typically used in conventional designs. This eliminates a number of components which used to be considered indispensible in the past, as, for example, the fairly complex and expensive distributor tiles, perforated distribution pipes or stand-by blowers.

Peter Kordt, Managing Owner of Wire Körner, expects significant cost reductions for his customers: „The simplicity of the design has obviously convinced our customers. The new technology saves up to 15 percent of energy compared to conventional furnaces. Also the savings on maintenance will be significant, because what does not exist does not need to be serviced or maintained.“

The absence of the distributor equipment markedly reduces flow resistance of the combustion gas inside the furnace. Hence the required blower capacity can be lower than that of competing designs by about 20 percent. Not only the smaller blower unit but also the overall simplified furnace design will markedly reduce capital costs. Additionally, the new design no longer requires a stand-by blower, which was necessary in the past to provide cooling air to cool the steel structures in the event of a power failure.

As the combustion gas is premixed outside the furnace, the new design achieves a uniform fuel-air mixing ratio throughout the fluidized bed and a homogeneous temperature distribution over the width and length. This results in higher combustion efficiency and lower emissions of unburned hydrocarbons.

Through carefully customized control algorithms, efficiency is maximized at all loads. This saves up to 15 percent energy. For a typically sized furnace, this means more than 7,000 euros per year saved on energy.
