Stepping machinery occupies a large proportion in the metallurgical industry, and a large amount of "potential energy" released by these equipment during the descending process is converted into heat and "wasted";

The potential energy recovery technology developed by Shanghai Xuanding Technology, as the most representative innovative technology, can achieve energy saving of 30~60%;

Compared with the potential energy recovery solutions provided by other companies, Shanghai Xuanding's product features are as follows:

1. The potential energy cylinders involved in the system are all general-purpose hydraulic cylinders, which do not require special customization. The rest of the hydraulic components and accumulator groups involved are conventional models, and the procurement of spare parts is convenient;

2. Determine the optimal implementation plan according to the actual working number of main pumps of the heating furnace equipment, the weight ratio of the stepping equipment to the steel billet in the furnace, and the stepping rhythm (to ensure the optimal investment and energy saving ratio):

(1) Single potential energy recovery method: recover the potential energy of the stepping equipment (full recovery)

Advantages: low system investment, no additional energy consumption without a charge pump, basically no leakage, and high efficiency;

Disadvantages: The energy saving rate is lower than that of dual potential energy recovery;

(2) Dual potential energy recovery: simultaneously recover the potential energy of the stepping equipment and the billet in the furnace (segment recovery)

Advantages: high energy-saving yield, up to 60%;

Disadvantages: high system investment, need to set up a charge pump, extra energy consumption, and complex system;

(3) Which method is finally selected needs to be compared and checked according to various factors such as the billet load of the original heating furnace, the weight of the stepping equipment, the stepping cycle, the number of the main pumps of the original hydraulic station, and the original conditions to determine and check. choose the best solution;

3. Provide a system solution for the overall action sequence of the heating furnace. According to the output of the heating furnace and the requirements of the tapping rhythm, the chain conditions and action sequences of the loading and tapping machine, loading and unloading furnace door, furnace bottom machinery, roller table, etc. Carry out the optimal design to achieve the optimal match with the implementation of the potential energy recovery system;
