At that time, due to factors such as environmental protection, raw material costs, and human resource expenses, the forging company prioritized the use of pit-type annealing furnaces. The trend is towards intelligence, high reliability, high quality, service, and energy conservation and environmental protection, especially for forging companies producing multiple alloy grades. Under the circumstances at the time, the company's requirements included the following points, which should be key considerations when selecting pit-type annealing furnaces.

Enhanced power density, with energy consumption capped at 600 kW/t.

2. Suppliers offer strong service capabilities, high quality, and rapid response times.

3. The furnace, power system, cooling system, and tilt furnace system feature high quality, reliability, durability, and high automation levels. They provide clear indication, alarms, diagnosis, and fault handling for all systems.

4. Detailed technical documentation and guidance for usage, maintenance, and care should be provided, along with the establishment of long-term cooperative relationships. The pricing for non-standard parts must be reasonable.

5. High-quality products with comprehensive features, which can eliminate many frustrations during use.
