NextGen® System for Tokyo Steel

Tokyo Steel's Tahara Works in Tahara-shi, Aichi, Japan, has placed an order for one NextGen® system for their DC EAF-Consteel®.

With ten NextGen® systems in North America showing excellent system performance and quantifiable process improvements, Tokyo Steel Co., Ltd., Tahara Works in Tahara-shi, Aichi, Japan, has placed an order for one NextGen® system for their DC EAF-Consteel®.  The NextGen® sale represents the 8th offgas system and the first NextGen® system to be supplied by Tenova in the Japanese steel market.

Tenova’s proprietary NextGen® system is a hybrid/extractive offgas technology system that delivers fast analytical response times and the most complete spectrum of process analysis (CO, CO2, O2 and H2).  The NextGen® sale was a result of joint collaboration by Tenova Goodfellow Inc. (TGI) and Sumitomo Shoji Machinex Corp. (SMX) to bring breakthrough technology to the Japanese Steel Industry.

The NextGen® system will be installed on Tahara Works existing 420 ton DC EAF furnace and the largest capacity Consteel® in the world.  The scope of supply includes proprietary NextGen® system hardware, inclusive of two sampling stations, one central multi-point analyzer and Optical Velocity Measurement (OVM) for downstream analysis, a key component to understanding the carbon evolution.

Other project deliverables include a scrap tracking system, improved HMI displays and CFD modelling for the analysis of the EAF and preheat tunnel to determine mass flow in the EAF and Consteel®, cold spots to enable Tenova to provide a full process optimization solution for the customer. Commissioning of the system is expected to take place in the summer of 2018.
