Titanium explosion composite board is a key material in the following industries:
1. Chemical industry: Chlor alkali industry (ion membrane electrolyzer, wet chlorine gas cooler), PTA (purified terephthalic acid) plant, acetic acid plant, various reaction vessels and towers.
2. Ocean engineering: seawater desalination devices, ship components, and seawater cooling systems for offshore platforms.
3. Power industry: flues, baffle doors, absorption towers, etc. of power plant flue gas desulfurization (FGD) systems.
4. Pharmaceutical and food industries: occasions with extremely high requirements for material purity and corrosion resistance.
5. Environmental protection equipment: Corrosive environment in wastewater treatment, garbage incineration and power generation.
Subsequent Processing and Precautions for Titanium Explosion Composite Plate Composite Plate:
After the production of titanium explosion composite plates, a series of processing steps are required, among which special attention should be paid to the characteristics of titanium:
Heat treatment: Very careful must be taken. The heating temperature should not be too high (such as below 650 ° C) and should be carried out in a vacuum or protective atmosphere to prevent oxidation of the titanium layer and growth of brittle phases. Forming processing (rolling, stamping): It is necessary to consider the different elongation and rebound of two metals; Welding: This is the core process of manufacturing composite equipment. Usually used:
1. Base welding: Use welding materials that match the base steel to weld the steel parts.
2. Coating welding: Use titanium welding materials that match the titanium coating to weld the titanium part. The most crucial step is the welding of the transition layer, which requires the use of special transition welding materials (such as tantalum or niobium based welding wire) to ensure the corrosion resistance and mechanical properties of the joint. The welding of the entire titanium layer needs to be carried out under strict argon protection.
Non destructive testing:
Combining interface quality: Ultrasonic testing (UT) is used to detect the presence of unbound areas in the binding rate; Defects in titanium coating: Penetrant testing (PT) is used to check for the presence of microcracks on the titanium surface.
Summary: Titanium explosion composite plate is a cutting-edge material technology that perfectly combines "noble" titanium with "civilian" steel. It solves the global problem of dissimilar metal bonding through the unique process of explosive composite, fully leveraging the advantages of both materials and playing an irreplaceable role in the field of high-end equipment manufacturing. It is the key to achieving long equipment life, high reliability, and low cost.
