Iron & Steel Metallurgy

1. Industry Demand

Steel metallurgy processes including blast furnace water cooling, converter flue gas waste heat recovery and rolling mill lubricant cooling feature extreme high temperature, heavy dust and impurity scouring with severe fouling and abrasion risks. Heat exchangers require outstanding heat resistance, anti-clogging, abrasion and corrosion resistance to adapt to fluctuating working conditions, ensure continuous heavy-duty production and realize energy saving and carbon reduction.

2. Core Working Stations

Core scenarios include blast furnace circulating water cooling, high-temperature converter flue gas heat recovery, rolling mill lubricant precise temperature control and low-grade waste heat utilization. Widely applied in full-process steel smelting, rolling and old plant renovation, it extends equipment service life and reduces comprehensive energy consumption per ton of steel.
