China Drying Network News Recently, the new type of granular calcium cyanamide calcium multipurpose chemical fertilizer industrial demonstration project declared by Darong Group was listed as the 2012 agricultural science and technology achievement conversion fund project, and it received 600,000 yuan for funding.

In recent years, the use of chemical pesticides to control diseases in agricultural production has virtually increased the pollution of land and agricultural products. In response, Darong Group, through years of research, has carried out the transformation and industrialization development of its own invention patent, particle-cyanamide-calcium cyanate compound fertilizer, and solved the formula design of cyanamide calcium dry granulation and slow-release fertilizer. Many problems such as the optimization of production process and the application of standardization have successfully developed a multi-functional drug fertilizer with the effect of combining drugs and fertilizers. The drug fertilizer has been tested and demonstrated on several kinds of crops in several counties in Ningxia, and the effect of pest control and production increase is obvious.

Cobalt Based Alloy Powder

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
