Steel production
Continuous casting plants
First bow-type continuous casting installation in the world
The procedure for pouring liquid steel to a strand was developed and affected by us. So our works successfully poured the world’s first bow-type continuous casting in 1964.

Continuous casting process
With continuous casting the liquid steel first goes through a water-cooled oscillating mould, which determines the cross section of the strand.
Afterwards the strand is led horizontally over rollers in an oval bow until it solidifies completely and can be divided. Cooling takes place either alone via water-cooled rollers (dry casting) or by spraying water.
Optimal plant technology and experience of many years permit the production of the highest quality continuous casting slabs, e.g. for processing into acidic gas resistant large tubes or into body parts with the highest finishing requirements. Altogether in Huckingen so far more than 50 million tons of continuous casting slabs have been produced.
In December 2000 a new slab casting plant was put into operation, which employs the vertical bending procedure. On the 1st of October 2001 the first casting on the slab continuous casting installation 1 took place (originally shut down in 2000), which can now produce products in the twin procedure with four strands.

Continuous casting plants
Two continuous casting plants are also at our disposal for the casting of round steel bars. Very good quality conditions of the plant I, which was put into operation in 1982 , led in direct consequence to the building of plant II, which took up production in 1984.
With the given tap weights of 275 tons, high casting speeds must be achieved with sequences of small cross sections. Extensive experience, with altogether over 20 million tons round steel bar gained so far, make successful control of this procedure possible, also with highest requirements of quality to the input material, e.g. for the manufacturing of alloyed boiler tubes, high-strength oil field pipelines and forged goods in all dimensions.
