New Generation Steel Strip Continuous Annealing

Hot Dip Galvanizing (Aluminizing) Technology --- JJRS-Sendzimir

After cold rolling, the highly worked non-grain-oriented electrical steel strip (NGO) is recrystallized in a horizontal continuous furnace and the grain size is adjusted by secondary recrystallization. A thin layer of insulating lacquer is then applied in-line with a roller coater, in order to reduce eddy current losses in the electrical motor and prevent corrosion. The process steps for this phase of production are as follows:

Multi-stage strip cleaning
Rapid strip heating in the heating up section of the continuous furnace (optionally with rapid heating systems up to 500 K/s)
Option: decarburization to prevent magnetic aging
Annealing for recrystallization and discontinuous grain growth in process atmosphere
Controlled cooling in the slow cooling zone and final cooling zone
Coating by roller coater and drying in a floater furnace

Process simulation before heat treatment makes it possible to identify suitable annealing programs to achieve the specified magnetic and mechanical properties
Hydrogen regeneration units, which provide hydrogen savings of up to 50 %, are available
