In order to make full use of resources, some repair work needs to be done, which can significantly reduce costs.
Add another layer of metal to the old copper mould tube. That is, at room temperature, the metallic nickel, metallic cobalt and rare earth elements are synthesized on the surface of the workpiece with the help of an external magnetic field. A high temperature resistant and wear resistant composite material with heavy metals as the base material is formed.
Use this technology to rebuild and repair the replaced copper mould tube, which can be used repeatedly and never scrapped. Its core is to form a layer of self-lubricating, wear-resistant, high-temperature resistant and high-strength alloy material on the inner working surface of the copper mould tube. This material is more superior than the original working layer and the service life is longer. The excess steel volume is more, and the cost per ton of steel is lower and more economical.
Through the bimetal manufacturing technology, the copper mould tube unifies the advantages and characteristics of the two metals to achieve special mechanical properties that are difficult to achieve with a single traditional material. It not only has the high heat transfer performance of copper, but also the high wear resistance and corrosion resistance of the inner layer of special metal.
