Recently, Weihua build a large annealing furnace for large carne parts processing, which improves the overall processing capacity of large capacity metallurgical crane parts such as reducer, trolley, etc.

1.Full-size crane parts processing capacity

With large-scale CNC floor boring and milling machines with 260mm and 200mm spindles, CNC gantry boring and milling machines and other equipment, as well as corresponding processing tools, it has a full-size, high-precision processing capability coverage for large metallurgical crane structural parts of 300t-500t and above.

2.Combined processing

The processing mode is changed from single-piece processing to combined processing, and the whole process quality control mode is constructed.

3.Overall machining precision

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.

Weihua carried out many metallurgy crane projects for many big steel plants in China and overseas.
