Energy Saving Technology of Rolling Mill System
Recent years, regenerative combustion technology has been widely used in heating equipment. Compared with the heating furnace without waste heat recovery, regenerative heating furnace can save more than 40% energy. However, the investment cost is high, and there is the concept of saving energy without money saving. Recently, double regeneration (preheating gas and air 1000℃) technology is recommended for heating furnace to use surplus blast furnace gas. The efficiency is higher than 70%, and the energy saving is obvious.
