The new ingot casting plant at the<br />

Essen works of Trimet <strong>Alu</strong>minium<br />

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 />
