New Expansion of Batch Annealing Plant


New Expansion of Batch Annealing Plant

BILSTEIN places Order for Expansion of Fully Automatic Batch Annealing Plant to Tenova LOI Thermprocess.

In December 2017 the company BILSTEIN based in Hagen-Hohenlimburg, Germany placed the third follow-up order to Tenova LOI Thermprocess in Essen for the expansion of the fully automatic batch annealing plant. This furnace plant is the only batch annealing plant in the world with fully automatic stacking of coils and intermediate convectors, an automatic coupling of all media and fully automatic operation of protective hoods, heating hoods, and cooling hoods. Except one operator in the measuring station, no further operation personnel is required any more.

With the latest expansion of its batch annealing plant, BILSTEIN has strengthened its reputation as one of the most innovative companies in the industry and doubled the original quantity of annealing bases. The contract for stage I was placed in 2011 and consisted of twelve annealing bases with six heating hoods and six JET-cooling hoods. The plant started fully automatic operation in November 2012. After a successful test phase, the plant was expanded by four annealing bases in 2015 (stage II). In December 2017, the contract for stage III, consisting of eight further annealing bases was awarded. Production is scheduled to start in autumn 2018.

Hot- and cold-rolled steel strip coils with a coil weight of max. 30 t, an outer diameter of 1,000 mm to 2,000 mm and a coil width of 150 mm to max.1,350 mm are annealed in this plant.
