Aga chose Camcoil

When AGA’s incineration lab in Stockholm needed an effective way to load and unload steel into and out of its experiment kiln, they chose Camatec’s Camcoil reeling system.
“We develop world-leading technology, so we need good equipment,” says Bo Sundelin, the man at AGA responsible for the experiment kiln. “And Camcoil does the job.”
AGA not only produces gas, it is also one of the world’s leading developers of industrial technologies where heat and incineration – generated by gas – are the key determining features of the process. One of these technologies is DFI, direct flame impingement, in which a metal strip is heated by concentrating a burning flame directly on the strip.
“Through just a small extension of the kiln that the customer already uses for processing strip steel, and adding a turbo effect for the heat, we can introduce other processes, such as cleaning the surface and partial oxidisation,” explains Bo Sundelin. “This produces a very effective processing of the raw material for our customer.”
DFI technology is continually being improved. Previously, AGA fed its sample kiln with pieces of sheet steel that were cut to size and handled manually for most of the procedure.
“But to save time and give our customer a better picture of the process, with flows that related more accurately to a full-scale industrial operation, we needed a good reeling system. That’s why we chose Camcoil,” says Bo Sundelin.
AGA has been using Camcoil for some time now.
“It does the job,” confirms Bo. “It reels the steel efficiently in and out of the kiln, and we can run at different speeds, which is very important for us. The temperature varies, depending how quickly the steel passes through the flame.”
“Naturally, it’s much easier to have a reeling system than having to manually handle pieces of steel.”
Lennart Andersson, who has responsibility for Camcoil at Camatec, is very satisfied with the installation at AGA. “This was one of our larger installations of Camcoil equipment and it was a very demanding specification, which is always a stimulating challenge,” says Lennart.
The speed of the strip can vary from 1-400 metres a minute, with a width of 100-400 mm. Thickness can range from 0.1-1.5 mm. Because test runs in the oven usually take place with personnel from both AGA and their customer present, the safety requirements are very strict.
To enable the equipment to be moved aside when the work space is required for other activities, the reeling system was designed with two separate bottom frames, a winder section and unwinder section, with space for AGA’s DFI oven inbetween. To meet safety requirements the units are equipped with fencing and gates.
Camatec’s CEO, Peter Wigarthsson is keenly following the results of the use of Camcoil in AGA’s application.
“Camcoil is a unique product, and we have high hopes for it. Camcoil enables a major improvement in the efficiency of a reel handling system for all businesses that handle steel. This market is already large in Sweden, but we are also planning to launch Camcoil internationally, starting in Germany where the strip steel market is ten times larger than Sweden,” says Peter Wigarthsson, CEO of Camatec.
