Ipsen’s

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 applications in the

wind turbine industry.

Ipsen’s ATLAS technology focuses mainly on a

customized heat treatment process to produce steel

parts with the material characteristics required for the

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 with 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, tempering furnaces, handling tools for

component loads and cleaning systems. Ipsen’s

AutoMag 4.0 automation software is used for

automatic operation of the furnaces.

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.
