Tenova LOI Thermprocess is a leader in supplying industrial furnace systems for the heat treatment and melting of metals and is part of Tenova, a provider of sustainable solutions for the green transition of the metals industry.

This event marks an important milestone for the Ansteel Group achieving full coverage of electrical steel grades at Ansteel’s Silicon Steel Division. The new processing line puts the Ansteel Group in the position of highly efficient production of electrical steel for electric vehicles with very thin gauge, high magnetization density and low material loss thus entering the first tier of the industry.

Tenova LOI Thermprocess’ Annealing Furnace “ACL” for non-grain oriented (NGO) electrical steel strip is specially designed for high annealing temperatures, high H2 content in the process gas as well as high strip processing speed. Advanced cooling systems guarantee low cooling rates and most uniform cooling effects across the steel strip width, which are crucial for high grade NGO electrical steel strip, especially for electrical vehicles (EV).

A modern process gas separation concept enables the furnace sections to run under different process gas combinations. Tenova LOI Thermprocess intelligent mathematical models are integrated in the furnace control PLC to fulfil the demanding requirements for strip annealing accuracy and stability.

The completion of the complex project as first production line of this kind in Northeast China will enable the Ansteel Group to grow as global player in sustainable steel and facilitate a green path to industrialization.
