Moving the needle

Processing equipment engineers take theories into working reality

August 2021 - A smattering of steel and aluminum manufacturers around the world have stealthily become integrated producers—not only by owning scrapyards and downstream fabrication companies but also by bringing high-volume metal processing lines in house. They are relying on full-service machinery builders like SES-Salico to achieve that.

SES-Salico is a joint venture between SES LLC, Alliance, Ohio, and Salico Group, Molteno, Italy, that formed in 2015. Founded in 1976, SES specializes in heavy-duty mill equipment, including melt shop components, transfer cars, slab and coil handling, long product handling and processing lines. Salico Group, established in 1978, builds slitting, cut-to-length, leveling, blanking and packaging lines.

Cesar Martin, technical operations manager, and Daniel Cullen, manager of sales and service, discuss how the collaboration has delivered value to customers.

“Our lines are predominantly on the heavier side, and we manage heavier material handling from melt shop to hot mill to cold mill,” Cullen says. SES has long built its expertise within mill environments while Salico specializes in equipment for processors.

SES has nearly 50 engineers on staff. With the SES-Salico joint venture, the Italian company now has a U.S. partner with a solid domestic footprint and that can service existing lines, rebuild machinery, and engineer and manufacture new components.

Domestic builds

Steel Dynamics Inc. sought to install a slitting line at its Butler, Indiana, complex, says Cullen. Many mill customers may look at slitter builders as designing equipment for lower volumes. “A lot of slitters are designed to run eight hours a day. A mill runs 24 hours a day. We are rebuilding a line to a steel mill specification,” he says. “Salico is doing all the automation and controls. We are working hand in hand on these projects. Wherever there is a gap, we look at existing designs from both companies to fill it. If nothing fits, then we have capabilities at each end to design the project to match customer needs.”

Salico has built three processing lines for an aluminum mill in Tennessee. “We supplied two side-trimming and center-cut lines and one coil inspection line,” says Martin. The mill automated inspection on the side-trimming line. Because the material goes to automotive customers, “they must look for the smallest defect.”

The lines Salico built include coil thickness gauges, leveling, marking and dry coating functions. “They have all the bells and whistles. These lines are bringing back—in house to the mill—processing that they were outsourcing. They are saving a bunch of money on service and logistics and can control quality in a more agile way, detecting defects much earlier in the process,” Martin explains.

More producers are considering installing processing lines within their mills, says Cullen. “At SES, we are in the mills every week. We understand all the mill requirements. Outside processors don’t like to hear when the mill puts a line in. The mills, however, love it,” he notes.

European style

Many of the joint venture’s processing lines must perform multiple tasks. “It’s a slitter with inspection and rewind capability and, it sounds obvious, but most equipment builders do not do all of that, or cannot do all of that very well,” Cullen says. So the North American market is “stuck” with designs from the 1980s and 1990s.

Capital spending decisions are largely “driven by price. [Clients] don’t want to spend a lot on engineering and they want to keep costs low. But we will bring years of advancement to a line, which now competes with a line the customer may have bought in 1995.” The customer will be able to tell immediately which one performs best.

When the two companies performed their due diligence before the 2015 merger, “it was fascinating to see what Salico has and what was normal in the EU market. We wondered, why wouldn’t we do that?”

For example, “we are seeing a lot of interest in automation,” which is more common at European metals factories, “It’s already developed and in service. These are not theories.”

The way the market works in Europe, says Martin, is “we take for granted that each line is tailor made.” Salico does leverage existing developments but “no line is typical.”

Martin previously worked with a drives and controls/automation giant that tried to standardize its PLCs and drives. “In a way, they asked us to have line types A, B and C and be ‘flexible’ enough to allow customers to decide on the color. That wasn’t really helping our customer because each wants an individual solution and for us to be more flexible.”

Salico has instead developed a series of solutions that can apply to multiple requirements, but its engineers still expect to tailor those solutions based on customers’ real-world needs.

“Another driving force for us is that safety requirements in Europe have been stringent for a long time, which led the market to develop certain automation solutions to provide greater safety—but without handicapping the productivity.”

Error reduction

When slitting, operators must switch from one setup to the next by changing out knives and separator discs before the recoiler. The classic method, says Martin, is to unload each arbor one by one and insert the new tools at each turnstile. “That was all done manually. We are seeing greater automation for these setups.” Automation prevents operator injury because he or she no longer has to lift and carry heavy tools.

Automation also reduces or eliminates errors that manual operation can bring. “Approximately 5 percent of setups may contain an error,” Martin says. “That means one has to strip that piece out of the slitter head; it means scrapped material and down time. Automating that reduces workload and the number of operators you need,” lowering the cost of production.

Martin concedes that automation can add significantly to the cost of a new slitter but it will become standard, he predicts. Interest is growing among the top tier of U.S. processors and service centers in the U.S. Eventually, “that will cascade from the top customers down to [mid-size] processors and service centers. We are getting inquiries from U.S. customers. It starts with the top of the class.”

Automating metal processing lines “is almost a paradigm shift” for some potential buyers, Cullen says. “They’re having a hard time figuring out how they would implement the robotic aspects. They can’t always visualize it.”

But across the Atlantic Ocean, he says, “there have been multiple generations of robot knife changers. People here are just starting to get into that but Europe is probably on the third generation.”

Interest grows

Martin says orders for robotic components have grown incrementally since Salico built its first one in 2006. “That was built from scratch and was one of a kind. In 2010, we built two. In 2015, we delivered another couple of them. But in the last couple years, we have received many more orders.” In the past year, “we have delivered two, and three more are in the works.”

In the recent past, perhaps 1 percent of the lines were automated globally, says Martin. Now, 70 percent of the new lines have automated separators, and over 40 percent have automated loading of slitter heads. “That rate is still going up. The benefits are there and customers realize it.”

SES-Salico is aiming to move a piece of the setup into position in a mere 12 seconds, says Martin. With that kind of potential productivity gain, says Cullen, “we are trying to get past where everyone is now.”

The ease of use is going to be key. The machine operator can input instructions such as how many cuts and the width of each cut, or these instructions can just be fed directly from other departments, like IT. “In the time you take to load the next coil, the computer has done the setup. Productivity goes up exponentially,” he says. MM
