A significant feature of titanium plate is its strong corrosion resistance, which is also formed by the characteristics of this material. However, in the actual use of titanium heat exchanger equipment, our requirements for titanium heat exchangers are also quite strict. So, next, the editor will provide you with some methods to improve the surface quality of titanium materials in titanium heat exchangers.

The quality of titanium plates largely depends on the smelting process, including the chemical composition of titanium, the cleanliness of titanium water (gases, harmful elements, inclusions), and the quality of the casting billet (component segregation, decarburization, and its appearance), which are key control points for smelting operations. In addition, industrial titanium plates also require sufficient hardenability to ensure uniform microstructure and mechanical properties of the entire tension spring section.

Titanium plate blank forging is usually used to produce products with similar appearance and standards, followed by only heat treatment and cutting processing of the blank. The casting temperature and deformation degree are the fundamental factors determining the structure and function of titanium alloys. The heat treatment of titanium plate blank products in factories is different from that of steel, and has no decisive effect on the microstructure of titanium alloys. Therefore, the process standards for forging titanium plate blank products in factories have a unique and important effect.

In order to achieve high strength and plasticity of titanium plate blank products and factory die forgings together, it is necessary to ensure that the overall deformation of the blank is not less than 30%, the deformation temperature does not exceed the phase change temperature, and the temperature and deformation degree should be distributed evenly throughout the entire deformed blank as much as possible. Uniformity of structure and function of titanium plate blank product factory die forgings, stainless steel forgings.

After recrystallization heat treatment in the highly active area of the metal, its low magnification is ambiguous crystal, and its high magnification is equiaxed fine crystal; In difficult to deform areas, due to small or no deformation, the organization often preserves the condition before deformation. Therefore, when forging some important titanium plate blank product factory parts, in addition to controlling the deformation temperature below TB and appropriate deformation degree, it is very important to control the microstructure of the original blank. Otherwise, coarse grain structure or certain defects will be inherited into the forging, and this cannot be eliminated by future heat treatment, which will lead to the invalidation of the forging.

When using the closed die forging method to forge titanium plate blank products for processing, the lifespan of the mold decreases due to the high pressure. Therefore, it is necessary to strictly limit the volume of the original blank in closed die forging, which makes the material preparation process messy.

The above is a description of the methods for improving the surface quality of titanium plates by titanium plate manufacturers based on their own experience, hoping to be helpful to everyone.
