F. Nie<strong>de</strong>rmair, Hertwich Engineering<br />
At its plant in Essen Trimet <strong>Alu</strong>minium<br />
SE has set up an air-cooled ingot casting<br />
unit. The installation, supplied by Hertwich<br />
Engineering, supplements the range<br />
of equipment at the casthouse in Essen<br />
and extends the company’s <strong>de</strong>livery options.<br />
The business mo<strong>de</strong>l of Trimet <strong>Alu</strong>minium has<br />
ma<strong>de</strong> it possible for the company to produce<br />
aluminium successfully even un<strong>de</strong>r the by no<br />
means favourable local conditions that prevail<br />
in Germany. Trimet regards itself as a materials<br />
partner for aluminium processors, offering<br />
its customers tailor-ma<strong>de</strong> products. In support<br />
of that claim the company has continually exten<strong>de</strong>d<br />
its product range.<br />
Currently Trimet produces some 150 different<br />
formats in 450 alloys (including bright<br />
materials) as well as <strong>special</strong> gra<strong>de</strong>s in accordance<br />
with customer specifications. In this, an<br />
important role is played by products for the<br />
manufacture of safety-relevant components<br />
for the automotive industry, which can be supplied<br />
with a zero-<strong>de</strong>fect guarantee after being<br />
tested on Europe’s most mo<strong>de</strong>rn ultrasonic<br />
(US) testing unit.<br />
Casthouse extension for new products<br />
For its extensive product range the casthouse<br />
in Essen has the following equipment in total:<br />
• 14 furnace units and another furnace for<br />
melting down swarf and chips<br />
• nine vertical continuous-casting units for<br />
semis in various formats<br />
• one continuous-throughput and eight<br />
batch homogenising furnaces<br />
• a fully automatic US-testing unit for<br />
round bars<br />
• a horizontal continuous-casting unit for<br />
ingot production, and<br />
• an R & D continuous-casting plant,<br />
including its own homogenising furnace.<br />
The plant produces around 250,000 tonnes<br />
a year, of which 160,000 tonnes come from<br />
the company’s own primary production and<br />
90,000 tonnes from recycled material.<br />
Ingots of casting alloys can optionally be<br />
produced by horizontal continuous casting<br />
