Steadily rising! The high-strength steel processing service of Daming boom Steel is strong and has obvious advantages

According to data from the China Construction Machinery Association, the domestic sales of many mainframe manufacturing enterprises have declined year-on-year this year. Except for aerial work platforms, the sales growth rate of other construction machinery products has slowed down. At present, the market capacity of aerial work platforms is 200,000 to 300,000 units per year. Against this backdrop of the industry market, how is the supporting service situation of Daming in the aerial work platform market?

Steadily rising!

On the one hand, due to the safety hazards of scaffolding and the need for the renovation of old and dilapidated residential areas in the country, the demand for aerial work machinery will continue to rise in the next three to five years. In addition, Daming's forward-looking marketing strategic layout has intensified its efforts in the development and service of the aerial work platform market in the second half of the year. More importantly, in the processing service of high-strength steel boom steel, Daming has strong process support capabilities.

The excellent uncoiling and flattening service model of Daming

The core process of steel processing for the boom of a aerial work platform is stress relief to ensure the straightness of subsequent cutting, the consistency of bending, and to prevent welding deformation. Generally, stress relief requires steel mills to treat hot-rolled plates by tempering them. However, considering factors such as the steel plant's production capacity and tempering process, the steel plant's recommendation of only 700 mpa boom steel with tempered plates cannot better meet the customer's delivery time and cost requirements.

In Daming, the supply of boom steel relies on advanced uncoiling equipment and uses coiling and leveling methods to achieve a stress relief level of over 70%. It can also respond to customers' processing demands such as multiple specifications and improved material utilization. In addition, the delivery time of the coiling flat plate is fast and the processing efficiency is high, which can achieve batch matching. This innovative service model of replacing tempered plates in steel mills with coiling flat plates has been unanimously recognized by upstream and downstream partners.

What are the manifestations of Daming in the matching of high-strength steel such as boom steel?

Advantages of Daming crane boom steel processing and supporting facilities

A continuously strengthened hard power of advanced processing equipment

The requirements for internal stress control in boom steel are extremely high. Daming has developed a systematic solution in processes such as leveling, cutting, and bending. Through precise leveling, internal stress is effectively eliminated and the plate shape is improved. In addition to the advantages of high-efficiency cutting equipment and advanced equipment such as the Swedish Usviken 3000T bending machine, Daming's boom steel processing has frequently received large orders.

1. Cluster of leveling equipment

Daming's hot-rolled uncoiling equipment for crane arm steel is equipped with high-end uncoiling production lines from Europe and America such as FIMI, NOVA, and VIGANO. Relying on the coordinated straightening of the initial, rough, and fine passes, the yield strength of uncoiling can reach 1200MPa, eliminating over 70% of the tensile/compressive stress in the material. It can effectively control subsequent cutting and blanking, as well as prevent deformation during forming and welding. The uncoiling effect ensures flatness, diagonal ≤3mm, no obvious waves or warping on the board surface, burr deviation no higher than 0.1mm, and the maximum length error is ±2mm.

2. Cutting equipment cluster

Daming is equipped with internationally leading cutting equipment such as laser cutting, water jet cutting, plasma cutting, flame cutting and sawing machines from TRUMPF of Germany, Messer of Germany, Tanaka of Japan and Koike of Japan, as well as a 12KW Hans CNC laser equipment cluster representing the highest domestic equipment manufacturing level.
