Fascinating Heat Treats-HÄRTEREI REESE Bochum, Gear Hardening
In the world of “Fascinating Heat Treats” few are more interesting than one of the largest commercial heat treaters in Germany, a firm by the name of HÄRTEREI REESE (HÄRTEREI loosely translated into English would be “Hardening). Their capabilities are so unique that customers will literally ship their parts 10,000 miles to REESE because so few other options are available. And what makes the company so unique? The size of their pit carburizing furnaces which can handle parts up to 100,000 pounds. And here is a really scary thought-currently in Germany companies are paying some of the highest prices in the world for energy, 50 cent per KWh for gas and more than 25 cent per KWh for electricity. These photos and video give you some idea about the size of their furnaces.
“OCTOBER 2019; In Bochum, Germany we find commercial heat treater REESE one of the largest commercial heat treaters in the country. This is a family owned business with a long established history and the distinction of hardening some of the largest gears, shafts and pinions in the world. As a matter of fact the company regularly receives large parts from North America to heat treat for the simple reason that no company in North America has furnaces as large as REESE does. The centrepiece of their Bochum facility is a monster pit carburizing unit made by ROHDE Schutzgasöfen GmbH in Hanau, Germany. Able to handle parts up to 17’ in diameter, 17’ deep and up to 50 tons we never get tired of seeing this furnace in action which is why their name comes up today. We just received this video from the company showing a typical part (at least for REESE) being heat treated. The other photos show the management team in one picture with Gord Montgomery of “The Monty Heat Treat News” on the left and in the other the ROHDE furnace shortly after it was installed.”
