Please note that the show monument is NOT barrier-free due to its historically left construction!

The centerpiece of the show monument is the Gas Dynamo Machine III built by Thyssen & Co. in 1923.

At 22 meters long, it is the last surviving large gas engine in the new German states. It was in operation for 65 years as a generator with an output of 2 megawatts. Purified blast furnace top gas was used as the working medium. For 35 years it worked exclusively for the Maxhütten network. It was decommissioned at the turn of the year 1988/89. For demonstration purposes, the movements of the gas dynamo can be slowly reproduced by means of a trolley over the flywheel. In addition, you can hear the original sound of the gas center from a bygone era. A short video (excerpt from a DEFA film) shows the machine in operation...

The gas engine shown here is located in the "Kokerei Hansa" show monument in Dortmund. It can be operated with compressed air as a substitute and is very similar to ours.

The video was recorded on 11.09. 2022 for the Open Monument Day.

A blast furnace model and the mouth of a blast furnace

Learn how pig iron was smelted from iron ore, lime and coke. The liquid iron was "tapped" from the mouth hole. Tapping at the blast furnaces took place about every 4 hours.

The pig iron melted in the blast furnaces flowed through the tapping chute into large ladles. From here, after desulfurization, it went to the converter steel mill, where it was refined into steel.  About 5-10% was cast into ingots and delivered to foundries.

The rollers of the block road

They are part of the listed facilities in the gas machine center.
The ingots coming from the steel mill were pre-rolled on the ingot mill. They were given their final profile in the duo or triog stand and, from 1985, on the combined section mill (KFS).

One converter (outdoor)

In 1974, the technologically obsolete Thomas process was replaced at Maxhütte by steel production in the bottom-blowing oxygen converter (increasing output and improving steel quality).

Workshop preserved in the original...

... with drilling machines, lathe, forge fire and anvil, workbenches and much more.
It is still used for restoration work in the gas engine center.

2 diesel locomotives (outside) ...

... with narrow-gauge wagons typical of the smelter: block transfer wagons, buckets for electric steel and blast furnace slag, wagons for scrap supply to the steel mills.

In the basement...

 ... there is another part of the exhibition about the former iron ore mines of the Maxhütte and a small mineral exhibition.

New since May 2014 ...

 ... is the part of the exhibition dedicated to renewable energies. 34 display panels and some demonstration objects inform about the interesting topic as well as different films, which can be watched in the media library.
