Products Description
Turbine elbow castings are common parts in turbomachinery used to change the direction of fluid flow. Turbine elbow castings are usually made of high-temperature alloy materials to withstand high-temperature and high-pressure operating environments. These castings often have a complex internal structure that effectively directs the fluid and minimizes energy loss. Turbine elbow castings are widely used in aviation, aerospace, energy and other fields, and play a vital role in improving equipment efficiency and performance.
(1) Material selection
The material of the turbine blade is usually made of high-temperature alloy steel, nickel-based alloy, titanium alloy and other high-strength, corrosion-resistant, high-temperature-resistant metal materials. In the material selection needs to take into account the use of the environment, mechanical properties, processing performance and other factors to ensure that the blade has excellent performance.
(2) Mold preparation
Turbine blade mold preparation is an important part of the casting process. Generally use gypsum type, silica sol type, ceramic type and other mold materials, through CAD / CAM design and laser cutting or EDM and other methods to process the shape of the blade mold. The shape and precision of the blade mold have a direct influence on the shape and precision of the final blade.
(3) Pouring
Turbine blade casting casting link generally use vacuum casting technology. In the pouring need to control the melt temperature, pouring speed, mold temperature and other factors, in order to ensure that the blade molding and dense internal structure. At the same time, also need to pay attention to the safety of pouring operation and process stability.
(3) solidification and cooling
Turbine blade casting solidification and cooling is very important. In the solidification process, you need to control the temperature, time and other factors to avoid eddy currents, cracks and other defects. In the cooling process, it is necessary to use appropriate cooling methods to ensure that the internal temperature of the blade is uniform, the stress is small, and meets the specific organizational structure and performance requirements.
