Induction Heater

In Cold Mill Process lines such as CGL, EGL, PGL, CCL and CAL, the galvanized surface passed through zinc pot is heated for Zn-Fe alloying and is dried as post heat treatment by Induction Heater for improving of the corrosion resistance of metal surfaces and for releasing of strip hardening. Also Induction heater shall be installed on casting line and on rolling mill line to compensate dropped temperatures of slab/bloom edges were caused by solidified cooling or forced cooling water and it makes an optimum hot rolling temperature for the highest quality finished product and secure the roll life time of mill stands

Generally, the Induction Heater consists of heating coil generates electromagnetic field, high and/or low Frequency inverter & converter system which provides reliable power safely and efficiently through changing direct current and alternating current each other and the cooling-water system for preventing of overheating.

The main technological features are as following;

▶ High availability and reliability

▶ Maximized the heating efficiency and objective temperature control.

▶ Optimized cooling system for inductive heating coils and power supply panels.

▶ Reliable power supply system and less capital spear parts.

▶ Quick exchanging of spare parts and easy maintenance.

▶ Simple foundation and installation
