Vacuum atomization experimental metal powder making equipment
The vacuum levitation melting gas atomization powder making equipment uses the principle of intermediate frequency induction heating to melt the metal material under vacuum conditions (or inert gas), and at the same time uses magnetic extrusion and stirring to push the liquid metal away from the water-cooled copper crucible, in a suspended state , To avoid the crucible pollution of liquid metal. After smelting, the liquid metal flows out through the nozzle at the bottom of the crucible, is atomized by the high-pressure gas and quickly solidifies into powder, which can better control the alloy composition.

Open air smelting water atomization pulverizing equipment
Atmospheric smelting water atomization pulverizing equipment is a modern pulverizing equipment which uses the principle of medium frequency induction to work under atmospheric pressure to inject melt into the lower part of the tundish to realize high pressure water atomization and rapid solidification. In the process of water atomization, due to the strong impact of high-pressure water flow, liquid metal will form a large number of small metal droplets. During flight and settlement, metal droplets become spherical due to surface tension, and they quickly cool and solidify due to the cooling of water. Finally, spherical or irregularly shaped powder particles are formed.

Supersonic spraying equipment
The supersonic flame is a high-temperature, high-speed combustion flame flow produced by burning propane, propylene and other hydrocarbon gas or hydrogen gas and high-pressure oxygen in the combustion chamber or in a special nozzle. The combustion flame flow speed can reach Mach 5 (1500m/ s) above. Usually called HVOF (High-velocityoxygen-fuel). The powder is fed into the flame axially, and the sprayed particles can be heated to a molten or semi-melted state, and accelerated to a speed as high as 300-500m/s, or even higher, so as to obtain a high-quality coating with high bonding strength and compactness. . The supersonic flame speed is very high, but the temperature is relatively low. For WC-Co cemented carbide, it can effectively inhibit the decomposition of WC during the spraying process. The coating not only has high bonding strength, but is also dense and has excellent wear resistance. Its wear resistance greatly exceeds that of plasma sprayed coatings, which are equivalent to explosive sprayed coatings, and also exceed spot plating hard chromium coatings and molten spray coatings. It is extremely widely used.

Cold spray equipment
Supersonic cold spraying, also known as low pressure cold spraying, is a new type of metal spraying process. It is different from traditional cold spraying. It does not need to melt the sprayed metal particles. The temperature of the sprayed substrate surface generally does not exceed 150°C. The principle of supersonic cold spray technology is to use compressed gas to generate supersonic airflow through a zoom-type Lava tube, and send the powder into the supersonic airflow along the axial direction to form a gas-solid two-phase flow, which will hit the substrate in a completely solid state after acceleration , Large plastic deformation occurs and deposits on the surface of the substrate to form a coating.

Plasma cladding equipment
Plasma cladding technology is a new material surface modification technology that uses plasma beam as a heat source to obtain excellent wear resistance, corrosion resistance, heat resistance, and impact resistance on the metal surface. This technology melts the alloy powder synchronously sent to the surface of the workpiece under the irradiation of the high-energy plasma beam, and simultaneously melts the shallow layer of the workpiece surface, forming an alloy molten pool on the surface of the workpiece; after the high-energy beam is removed, the workpiece Under the action of its own rapid heat conduction and the radiation heat transfer of the air around the workpiece, the alloy molten pool is rapidly solidified to form a high-quality coating with uniform composition, compactness, fine and uniform structure, no microscopic pores and cracks, and a good metallurgical bond with the workpiece . Plasma cladding is a rapid non-equilibrium solidification process, which has multiple strengthening effects such as supersaturated solid-liquid strengthening, dispersion strengthening and precipitation strengthening. Compared with laser cladding and electron beam cladding, plasma cladding is a new surface modification technology with high quality, high efficiency and low cost.

Vibrating screen
The vibrating screen uses a vertical vibrating motor as the excitation source. The upper and lower ends of the vibration motor are equipped with eccentric heavy objects, which transform the rotational motion of the vibratory motor into a horizontal, vertical and tilted three-dimensional motion, which is then transmitted to the screen surface. Adjusting the phase angle of the upper and lower ends can change the movement trajectory of the material on the screen surface.
