The equipment manufacturing industry is often referred to as the “industrial basement machine†and involves many fields. According to the research of the relevant state departments and the actual situation of Hunan Province, the advanced equipment manufacturing industry as a strategic emerging industry will focus on the following eight major areas. .
1. Medium and high-end construction machinery equipment
Hunan Province has obvious advantages in the field of engineering machinery and equipment. The total scale and technological innovation capability have ranked first in China and have the basis and strength for rapid development. The “Twelfth Five-Year Plan†will focus on the development of 13 types of equipment products in the four major segments of modern construction machinery and equipment, new energy engineering machinery and equipment, modern port engineering machinery and equipment, and municipal public equipment. At the same time, we will focus on the development of four key components for high-end hydraulic components, high-powered engines, transmissions and heavy-duty axles.
2. High-end electric traction rail transportation equipment
Hunan rail transit equipment manufacturing has played an important role in the domestic market, ranking top in the domestic market in high-power delivery vehicles, urban rail vehicles, high-speed passenger locomotives and other fields. The “Twelfth Five-Year Plan†should focus on the development of eight categories of products for locomotives and urban rail vehicles. Focus on the development of high-power traction converter systems, traction substation equipment and other 10 types of key components.
3. New Energy Automobiles and New Automobile Varieties
The development of new energy vehicles in Hunan province started early, and it ranks among the domestic advanced level in the design and manufacture of automobile batteries and hybrid buses. The “Twelfth Five-Year Plan†focuses on the development of 11 types of vehicle products in 4 major segments, including hybrid vehicles, pure electric vehicles, new automobile varieties, and research and development of fuel cell vehicles. We will focus on the development of seven key components such as hybrid powertrain assembly, drive motors and control systems, and high-performance power batteries.
4, high-end numerical control mold
The development of the NC mold industry in Hunan Province has made some progress in recent years. It ranks among the leading domestic companies in terms of efficient grinding technology and research and development of super-hard and ultra-precision machining technologies. According to Luo Baihui, during the “Twelfth Five-Year Plan†period in Hunan, it will focus on the development of seven types of CNC high-speed precision grinding equipment, high-end CNC gear grinding machines, and high-precision CNC crankshafts.
5, large-scale metallurgy, mining equipment
Hunan Province ranks the leading domestic level in the research and development of large-scale mine special transport equipment. Large-scale mining and site transfer equipment research and development have certain comparative advantages. The “Twelfth Five-Year Plan†will focus on the development of seven types of products, including 200t and above electric wheel dump trucks, large bucket wheel stackers and reclaimers, large-scale shovel shovels with 23 cubic meters or more, and large-scale liquid seal ring coolers.
6. High-tech ships and marine engineering equipment
Hunan Province is still in the early stages of development in the field of high-tech ships and marine engineering equipment, but the scale of production and sales of middle-to-high-end yachts has ranked first in the country. The “Twelfth Five-Year Plan†focuses on the development of 9 large-scale offshore pile foundation equipment, large-scale offshore lifting equipment, fairway dredging equipment, and new composite large-scale yachts.
7, aviation equipment
Hunan Province is at the leading position in the field of small and medium-sized aerodynamics, helicopter deceleration transmission systems, aircraft take-off and landing systems, and aerospace materials. The "Twelfth Five-Year Plan" focuses on the development of six types of products in the three categories of aircrafts, key sub-systems and aviation maintenance.
8, space equipment
Hunan has a leading position in the field of inertial technology products, near-space vehicles, satellite ground equipment and applications, and aerospace special materials. The "Twelfth Five-Year Plan" focuses on the development of six types of products, including the total space model, space subsystem, and aerospace service industry.
Cobalt-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent high-temperature properties and resistance to wear and corrosion. These alloys are typically composed of cobalt as the base metal, with various alloying elements such as chromium, tungsten, nickel, and carbon added to enhance specific properties.
The use of cobalt-based alloy powders in PTAW offers several advantages, including:
1. High-temperature strength: Cobalt-based alloys exhibit excellent strength and resistance to deformation at elevated temperatures, making them suitable for welding applications that involve high heat.
2. Wear resistance: These alloys have a high hardness and resistance to wear, making them ideal for welding applications where the welded parts are subjected to abrasive or erosive conditions.
3. Corrosion resistance: Cobalt-based alloys offer good resistance to corrosion, making them suitable for welding applications in aggressive environments, such as those involving chemicals or saltwater.
4. Thermal conductivity: Cobalt-based alloys have good thermal conductivity, allowing for efficient heat transfer during welding and reducing the risk of heat-affected zone (HAZ) defects.
5. Compatibility with other materials: Cobalt-based alloys can be easily welded to a wide range of base metals, including stainless steels, nickel alloys, and other cobalt-based alloys, providing versatility in welding applications.
To use cobalt-based alloy powders for PTAW, the powder is typically fed into the plasma arc using a powder feeder. The powder is then melted by the high-temperature plasma arc and deposited onto the workpiece, forming a weld bead. The specific welding parameters, such as arc current, travel speed, and powder feed rate, will depend on the specific alloy and application requirements.
It is important to note that the selection of the cobalt-based alloy powder should be based on the specific welding application and the desired properties of the final weld. Different cobalt-based a
