Taisheng pit annealing furnace is a standard energy-saving cycle operation annealing furnace in my country. Long rod-shaped workpieces, such as barrels, turbine shafts, rotors, etc., are vertically loaded and heated in the Taisheng pit furnace to prevent bending and deformation. All active controls of the Taisheng pit annealing furnace cover are protected by safety. When the furnace cover is open, the control power supply is automatically cut off. Heating can only start when the furnace cover is locked to ensure the safety of operators. At that time, foundries gave priority to using Taisheng pit annealing furnaces for reasons such as environmental protection, furnace materials, and human resource costs. Intelligence, high reliability, high-quality service and environmental protection are its development trends, especially in foundries with multiple trademarks. The advantages are more prominent. Under the current situation, the company requires several points, which are also the key considerations when selecting the Taisheng pit annealing furnace. The pit annealing furnace improves specific power and the power consumption is controlled at 600kW/t. The supplier has strong service capabilities, high quality and fast response speed. The pit annealing furnace body, power supply system, cooling system, and tilting system are of high quality, good reliability and durability, and have a high degree of automation. Each system can be displayed, alarmed, diagnosed, and fault-handled. The pit annealing furnace should have detailed technical information and technical guidance in terms of use, maintenance, and repair, and establish a long-term cooperative relationship. The price of non-standard parts should be reasonable. Products with high comprehensive quality can eliminate many troubles during use.
