What is the titanium alloy forging cooling methods?
What are the several titanium alloy forging cooling methods, in alloy materials, titanium alloy is the most commonly used metal material, titanium alloy forging demands, strict requirements, widely used in aerospace, medical equipment, the chemical industry, and other fields, in the process of titanium alloy forging, the choice of cooling method on the quality of the forging has an important impact, according to the performance of forging to choose a different way of cooling, the following is the small editorial compiled by a few kinds of titanium alloy forging Cooling methods
First, natural cooling
Natural cooling is a simple and commonly used cooling method. After the forging, the titanium alloy forgings are placed in the air and cooled by natural convection and radiation heat dissipation. The advantage of this method is that it is simple to operate and does not require additional equipment and energy consumption. However, the natural cooling speed is slow, which may lead to uneven internal organization of the forging, thus affecting the performance of the product.
Second, forced air cooling
Forced air cooling is through the fan or blowing equipment on the titanium alloy forging forced blowing, to accelerate its cooling speed. This way can effectively reduce the forging temperature, reduce thermal stress, and improve product performance. However, it should be noted that forced air cooling may lead to oxidation and hardening of the surface of the forging, so it is necessary to carry out reasonable control of the cooling speed and blowing distance.
Third, water quenching cooling
Water quenching cooling is a fast and effective cooling method. By immersing the titanium alloy forgings in water, the temperature can be rapidly reduced to obtain higher strength and hardness. However, water quenching cooling may also lead to problems such as cracks and deformation of the forging, so the cooling speed and temperature gradient need to be carefully controlled when used.
Fourth, oil quenching cooling
Oil quenching cooling is at a certain temperature of the oil cooling method. Compared with water quenching, the cooling speed of oil quenching is slower, which can reduce the risk of cracks in forgings. At the same time, oil quenching can also improve the surface quality of forgings to a certain extent. However, it should be noted that the oil quenching process requires strict control of the oil temperature, to avoid the oil temperature being too high to cause defects in forgings.
Five, vacuum cooling
Vacuum cooling is a way of cooling titanium alloy forgings in a vacuum environment. Under vacuum conditions, the heat conduction efficiency is higher, which can accelerate the cooling speed of the forgings. At the same time, the vacuum environment can avoid surface oxidation and contamination of forgings, which is conducive to maintaining the purity and performance of the product. However, the cost of vacuum cooling equipment is high, and the operation is relatively complex, so the actual application needs to be weighed according to the specific circumstances.
