After the furnace spheroidizing annealing, carbon tool steel, alloy tool steel, bearing steel and other non-oxidative decarburization, uniform spheroidizing structure, cold plastic deformation (such as stamping, cold heading, etc.) have been significantly improved. The mechanical properties of the steel after heat treatment fully meet the requirements of deep processing.
The main performance characteristics of the furnace:1. Well structure; it can be buried underground, with a small floor area, and is suitable for the technological transformation of old factories.
2. The loading capacity is moderate, about 9 to 15 tons per furnace, which is compatible with a batch of about 10 tons of a special steel wire variety, and the batch is convenient.
3. Electric heating is adopted, and the heat treatment process is automated, and the heat treatment process can be traced.
4. Furnace lining full fiber structure, the thermal efficiency is significantly improved, and energy saving.
5. A strong convection fan is installed at the bottom of the furnace, and the uniformity of the furnace temperature is good, the accuracy is ± 5 ° C, and the actual temperature reaches ± 3 ° C.
6. Adopting protective gas to achieve non-oxidative heat treatment with less metal loss.
7. Packing and other operations are convenient and reliable.
