Noncontact Measurement of Galvannealed, Galvanized Steel Strip
Ametek Land, a provider of infrared noncontact temperature-measurement technology, unveiled its Spot GS pyrometer, designed to accurately measure the tem- perature of galvannealed and galvanized steel strip. The pyrometer provides con- tinuous and accurate temperature meas- urement of coated steel strip during the galvanneal reaction, enabling users to accurately measure the temperature in a galvanneal furnace. This allows for opti- mum throughput rates in order to ensure consistent, high-quality, premium-coated steel, according to company officials.
The Spot GS enables automated fur- nace management to provide close control
of the reaction and position of the reaction zone, delivering tighter control of product quality. By maintaining control of the reac- tion zone, the pyrometer accommodates rapid changes of line speed and furnace power with variations to substrate or coat- ing weight. This allows for furnace opti- mization, thus reducing heating costs and maximizing throughput. Additionally, this will avoid excessive over-reaction and powdering/flaking of the coating during subsequent forming operations.
The pyrometer can be integrated with furnace controls, PLCs and control software. It has additional inputs and outputs includ- ing emissivity-out and LED switching,
which are available as analogue/digital control I/O as well as over Ethernet. Spot GS is available with the free-to-download SpotViewer software, which allows for the configuration, display and logging of data. In addition, Ametek Land offers a range of mountings and accessories compatible with all Spot pyrometers.

copper, brushed nickel or antique bronze, says Chin.
“The simulated stainless steel and other simulated coatings often are less expensive than the comparable laminate,” he says. “That’s because laminates usually fall into the thickness range of 4 to 8 mil, while the coatings measure well under 1 mil. And, because it is applied efficiently in a high-speed coil-coating process, it becomes less expensive to apply the coat- ing than a laminate, whether on a coil line or inhouse.”
The simulated-metal coatings with their accompanying substrates are formable, and reportedly can be made ductile enough to withstand even deep-draw forming. Unichem: www.unicheminc.com
Coatings Simulate Stainless Steel, Brass and Copper
Stainless steel, a premium material used to manufacture a variety of products, commands a high price that makes it unaffordable to many customers. In an innovative approach from Universal Chem- icals & Coatings (Unichem), a high-per- formance industrial finish comprised of a protective coating paired with a special substrate, part of the company’s uniPon line of interior decorative and performance coatings, is adhered to a variety of lower- cost metallic materials. T
he durable combination results in the brilliance of a polished and brushed stain- less-steel look while meeting or exceeding a battery of domestic-appliance tests, such as for kitchen and laundry appliances, and resists scratches, stains, chemicals
and fingerprints, according to company officials. A similar approach simulates a range of brass- and copper-coated products ranging from blinds and curtain rods to decorative food containers and tobacco tins as well as cosmetic and mason-jar lids.
“The simulated-stainless-steel finish basically is a durable protective-coating system that features a printed stainless- steel pattern on a variety of substrates, which can include tinplate, cold-rolled steel or other alloys depending on per- formance requirements,” explains Dan Chin, Unichem CTO.
By varying the coating color from clear to opaque in a variety of tints, the coating also can be made to look like brass,
Bio-Based Corrosion-Inhibitor Film for Steel, Aluminum, Copper
Daubert Cromwell has introduced the next generation of its Clear Pak-brand VCI films with Clear Pak 5000, enhanced to protect steel, aluminum and copper. The bio-based nitrite- and amine-free
packaging film, is recyclable, safe and simple to use, according to company offi- cials. Parts remain dry and ready to use, without additional cleaning or rework.
Target users: manufacturers and sup-
pliers requiring consistent anti-corrosion packaging of components at all stages of manufacture and storage.

Video Touts Coil Anodized Aluminum vs. Painted
Lorin Industries, Inc., Muskegon, MI, a producer of coil anodized aluminum, has released a new video highlighting the superior physical characteristics (durability
and color consistency, for starters) and cost efficiency of coil anodized aluminum versus painted aluminum. It also busts nine myths about coil anodizing, and
