Recently, a big annealing furnace was officially put into use at Weihua Crane Intelligent Industrial Park. This furnace dimension is16m×8m×6m which is used for annealing heavy structural parts and successfully carried out overall annealing of a 320t metallurgical trolley.

As the core processing technology of large metallurgical cranes, this annealing furnace can meet the annealing treatment of various structural parts of large metallurgical cranes with capacity above 500t, and the equipment processing capacity has reached the leading level in the lifting industry.

1. Precise temperature control

The furnace temperature control accuracy is ±3℃, and the furnace temperature uniformity in the same zone is ±10℃. It adopts PLC control mode to automatically realize multiple heating processes.

2. Intelligent control

Three-dimensional heat storage, zoned furnace temperature control, nozzle size and layout can be set according to actual needs, so that the workpiece is evenly heated in the furnace.

According to the product structure, Weihua has made a special annealing process, which can improve or eliminate various structural defects and residual stresses in the welding process, improve the comprehensive mechanical properties of the workpiece, prevent fatigue deformation damage and weld joint cracking, and eliminate Potential safety hazards to ensure the dimensional stability of each organization.
