Heating and heat treatment

Heating: 3 medium-frequency induction heaters (600 kW × 1, 1,200 kW × 2); 1 regenerative gas furnace, chamber 3.2 × 1.8 × 0.8 m.
Heat treatment: 4 automatic temperature-controlled box furnaces (3 high-temperature, 1 medium-temperature). The heat-treatment process is set by grade and customer requirement; furnace and cooling-medium temperatures are continuously monitored and recorded.
Quench cooling: 3 closed-circuit cooling towers (2 × 120 t, 1 × 60 t) with 2 water tanks. Furnace temperature uniformity (TUS) is re-measured to AMS 2750H every 12 months.

Material cutting

18 metal band saws; maximum cutting diameter Φ1300 mm.
