Zirconium is a rare metal material with extremely strong corrosion resistance. It has better properties than high-grade stainless steel, nickel-based alloys, and titanium materials in reducing or oxidizing environments. It has corrosion immunity to most acidic media. . Because zirconium material is very expensive, compared with pure zirconium or zirconium alloy, zirconium-steel clad plate with zirconium as cladding has been widely used in the field of container design and manufacture. However, based on the inherent process characteristics of zirconium materials and the special requirements of clad plate processing, it is difficult to manufacture zirconium steel clad plate equipment, and the process technology and quality requirements are correspondingly stricter, especially the explosion processing of clad plates, head pressing, zirconium material welding, etc. The process is more critical.
The quality of the zirconium steel-clad plate requires that the head be subjected to various complex external forces such as stretching, extrusion, and shearing during the pressing process. If the bonding quality of the composite board is not good, defects such as delamination, cracking, and bulging are likely to occur during the pressing process. Therefore, the bonding quality of the composite board is the premise of whether the head can be successfully pressed, and the quality of the composite board must be strictly controlled.
First of all, a professional metal clad plate manufacturer with mature explosion experience should be selected; secondly, the correct processing technology should be formulated and strictly implemented; finally, the clad plate should be sheared, bent, stretched, etc. according to the corresponding standards after stress relief annealing. With mechanical performance tests, and 100% ultrasonic testing, the fit rate is required to meet the design drawing requirements. In addition, due to the strong notch sensitivity of zirconium, in order to prevent pressing cracks caused by surface defects, if necessary, it is necessary to repair and repair the surface defects of zirconium cladding and conduct 100% penetration testing to ensure that there is no defect source.
