The 16m×8m×6m heat treatment annealing furnace for heavy structural was officially put into use in Weihua Crane Intelligent Industrial Park. It successfully realized the overall annealing of 320 ton metallurgical crane trolley frame.
As the core process and processing technology of large metallurgical cranes, this large annealing furnace can meet the annealing treatment of various structural parts of large metallurgical cranes of 500t and above.
1. Precise Temperature Control
The furnace temperature with control accuracy is ±3℃, and the furnace temperature uniformity in the same zone is ±10℃. Adopt 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.

After Annealing
Weihua has formulated a special annealing process according to the product structure, which can improve or eliminate various structural defects and residual stresses in the welding process, improve the comprehensive mechanical properties of the workpiece, and prevent fatigue deformation and damage of the workpiece and weld joint cracking, and eliminate potential safety hazards to ensure the dimensional stability of each organization.
Overall processing of large metallurgical crane reducer
1. Full-size processing capacity coverage
Large-scale CNC floor and gantry boring and milling machines with 260mm and 200mm spindles and other equipment, as well as corresponding processing tools forming a full-scale, high-precision processing capability coverage for large metallurgical crane structures of 300t-500t and above.
2. Combined process and combined processing technology
The processing mode is transformed from discrete single-piece independent processing to sub-component combined process and combined processing, and the whole process quality control mode is constructed.
3. Overall machining accuracy
It can realize the combined processing of large components and full-size large area, multi-directional boring, milling and drilling. The linear positioning accuracy is 0.02mm, the axis parallel accuracy of each hole system is 0.015mm, and the flatness of the joint surface is good.
