Annealing - a type of heat treatment of metals and alloys, comprising heating to a certain temperature, aging and then, usually, slow cooling. The purpose of annealing is to eliminate arising in the metal structure during molding, pressure treatment, welding deviations from the equilibrium state, i.e. Returns the crystal structure and homogenization. Annealing is carried out to reduce hardness and enhance treatment ability, improve the structure and achieve uniformity with the elimination of internal stress.

• Temperature control:high precision control of temperature changes, automatic process of heat treatment. The fan is mounted in the bottom of the furnace to ensure stable heat throughout the entire cooking process and maintain a uniform temperature, temperature accuracy is ± 5 degrees Celsius.
• Source of heating: Electricity or Natural Gas;
• Protective atmosphere:of ammonia or endo-gas and nitrogen purified protect steel from oxidation, decarbonization, preventing loss metal;
• Capacity:8 ~ 36 tons, takes slight party wire (≤ 10 t / party);
• Easy to use and install:the cover of the furnace is equipped with a pneumatic device opening and closing.
