Ipsen, a company specialized in heat treatment of steel, has recently supplied its ATLAS quench furnace to Dokka Fasteners, a Norwegian manufacturer of heavy-duty fasteners.
Ipsen ATLAS integral quench furnace
The furnace will be installed at Dokka’s new heat treatment plant in Auburn Hills, Michigan. Dokka will utilize the quench furnace to manufacture hot-formed steel fasteners for application in the wind turbine industry.
Ipsen’s ATLAS atmosphere heat treating equipment is a highly cost-effective machine and the operation and maintenance of it is easier. The equipment’s advanced design and technology helps to deliver high quality uniformity. The ATLAS technology focuses mainly on a customized heat treatment process to produce steel parts with the material characteristics required for this application. The fasteners depend on the technology of high-tension bolt assemblies, which are produced using high performance, heat treated steel alloys. These alloys provide fasteners, the capability to resist high loads of turbine operation and to remain unaffected by frost, storms and salt water during the estimated 160,000 thousand hours of wind turbine operation for 17 billion load cycles and over 20 years.
Dokka’s Auburn Hills-based heat treatment facility includes sealed quench furnaces for hardening of steel, required tempering furnaces, handling tools for component loads and cleaning systems. AutoMag 4.0 automation software of Ipsen is used for automatic operation of the furnaces.
