In the processing service of high-strength steel boom steel, Daming has a strong support of process supporting strength.
Daming’s excellent coil leveling service model
The core process of boom steel processing is stress relief to ensure straightness of subsequent cutting, consistency of bending and to avoid welding deformation. Usually, stress relief requires steel mills to hot rolled plate and then tempering treatment. However, in view of the capacity of steel mills and the tempering process, steel mills only recommend 700 MPa boom steel with tempered plate, which cannot better respond to the customer’s delivery and cost requirements.
In Daming, the boom steel supply is based on advanced leveling equipment, with roll leveling and flattening, the stress relief level is more than 70%, and it can also respond to the customer’s processing needs such as multi-specification and material utilization enhancement. In addition, the fast delivery time and high processing efficiency of roll leveling can realize batch matching. This innovative service mode of roll leveling instead of tempering plate of steel mills has been unanimously recognized by both upstream and downstream partners.
What does Daming have in the arm steel and other high-strength steel supporting?
Examples of Daming’s boom steel
As early as 2012, Daming was involved in supporting the main boom and outrigger boom of Zoomlion’s large cranes through the world’s top Usviken 3000T bending machine.
In 2014, we supplied Terex 600 tons crawler cranes and electric shovel stackers with underfeed.
In 2018, matched Liugong 25-ton crane boom, with a monthly capacity of 100 units
2019 established rolling order cooperation with Lingong, realizing the doubling of the processing efficiency of shear fork and straight boom, and really gaining a foothold in the construction machinery industry in the second half of the year.
In 2020, we will continue to support Lingong’s heavy machine down parts, undertake 100% orders for straight boom jibs, and support the main telescopic boom of Zoomlion’s global mass production of the largest tonnage 1800T all-terrain cranes.
In addition, Daming continuously improve the level of carbon steel supporting services, combined with customer demand, Jierger, Terex, Shanhe Intelligence, etc. to provide jib steel processing support, and recently succeeded in LiuGong, Lingong and the world’s top 10 aerial working platforms and other large customers to provide a high into the material, fast delivery, excellent quality jib steel processing support, the world’s top four companies have been served by two.
For the world’s top 10 aerial working platform enterprises supporting the new model of aerial truck boom; for the world’s top 50 construction machinery PLUS enterprise Lingong heavy machinery supporting arm aerial working truck boom and so on.
During this period, Daming keeps exploring the market, plowing into the needs of aerial working machinery customers, constantly consolidating the improvement of related product processing equipment, as well as the accumulation of process technology, and further enriching marketing, production and technical personnel, strengthening management, etc..
What are the differentiated competitive advantages of Daming in aerial working machine boom steel processing support?
Advantages of Daming’s boom steel processing
Continuous consolidation of the hard power of advanced processing equipment
Boom steel has very high requirements for internal stress control, and Daming has formed systematic solutions in the processes of leveling, cutting, bending, etc., to effectively eliminate internal stress and improve plate shape through precise leveling. Together with the advantages of high-efficiency cutting equipments and advanced equipments such as Sweden Usviken 3000T bending machine, Daming has frequently received large orders for boom steel processing.
1、Leveling equipment cluster
Daming’s boom steel hot rolling and leveling equipment, with FIMI, NOVA, VIGANO and other European and American high-end leveling production lines, relying on the initial, rough and fine three passes of linkage straightening, leveling yield strength of up to 1,200MPa, which can eliminate more than 70% of the material’s tensile/compressive stresses, and effectively control the subsequent cutting of the next material, and to avoid deformation in the molding and welding. The leveling effect ensures flatness, diagonal ≤ 3mm, no obvious wave, warping, burr deviation not higher than 0.1mm, and length error up to ± 2mm.
2、Cutting equipment cluster
Daming owns international leading cutting equipments such as laser cutting, water cutting, plasma cutting, flame cutting, sawing equipment, etc. from Germany Tonspeed, Germany Messer, Japan Tanaka, Japan Koike, etc., as well as 12KW Daqo CNC laser equipment cluster, which represents the highest level of equipment manufacturing in China.
3、Bending equipment cluster
▽The world’s top imported Swedish Usviken 3000T bending machine, which can bend the longest 15M and the thickest 100mm.
Typical advantages:
Bending force up to 3000T, can cope with long and thick plate bending processing
Special deflection compensation system to compensate for uneven thickness of raw material and mold wear.
A number of processing technology and mold design patents, can achieve one-time molding of spliced plates with different plate thickness (mainly serving shipboard business), can complete the bending and forming of super-long plates (more than 15 meters) (mainly serving special vehicles)
▽Huangforging 2000T CNC bending machine
Typical advantages: the longest processing 12 meters, every 1 meter with single-point deflection compensation.
▽Italy CoLgar 1600T CNC bending
Typical advantages: high efficiency, precise bending angle, good straightness.
Continuously improving production technology and other soft power
Daming also pays special attention to the accumulation of soft strength of technology and production team, and has successively cultivated a professional carbon steel processing service team. Under the leadership of Group Technology Center and the support of professional technical service team of each Daiming molecular company, the technical team personnel are also constantly exploring the process development and production of tooling and so on.
In addition, they will also communicate with customers to change the design and production process according to the actual situation of on-site production, in order to improve the processing efficiency, optimize the production cost, and help customers to really reduce costs and increase efficiency. With the close cooperation and high efficiency of the production and technical service team, Daming strives for the successful support in more projects of aerial working machines in the construction machinery industry, and further expanding the service reputation of Daming in the processing and manufacturing of carbon steel steel such as boom steel.
Daming is willing to cooperate with the upstream first-line steel mills to actively promote the processing technology of fixed-roll open plate, assist steel mills to reduce the energy consumption of tempering processing, release production capacity, and jointly bring customers in the aerial work platform industry a “one-stop” matching service with fast delivery, multiple choices, and excellent cost.
