At present, the crystallizer used in the metallurgical industry mainly comprises a slab crystallizer, a tube blank crystallizer, a roller type crystallizer for producing non-crystal, a special-shaped crystallizer with other shapes and the like. The molten metal is crystallized in the mold and contacts and rubs against the mold, causing the mold to fail due to dimensional deviation from the design value caused by wear. The crystallizer with high heat-conducting property and high wear-resisting property has longer service life. For this reason, the mother material of the mold is made of a copper alloy having good heat conductivity. At present, a layer of wear-resistant metal plating layers such as a metal Cr plating layer, a Ni-Fe alloy plating layer, a Ni-Co alloy plating layer and the like are electroplated on the surfaces of a copper plate blank crystallizer and a copper pipe blank crystallizer, so that the wear resistance of the surface of the copper crystallizer is improved, and the service life of the crystallizer is prolonged. For the crystallizer which is worn out of service, a machining method is adopted at present to remove the residual electroplated wear-resistant metal coating on the wear surface, and the wear-resistant metal coating is electroplated again and then is continuously used. In the process of machining and removing the residual wear-resistant metal coating after abrasion, a copper alloy layer on the surface of the crystallizer parent metal connected with the wear-resistant metal coating is also inevitably removed. The copper crystallizer after being treated for several times is scrapped because the thickness of the copper alloy layer on the surface of the mother material is greatly reduced. The roller crystallizer for producing the amorphous alloy is made of copper alloy. After the roller type crystallizer is used for a certain time, the surface of the roller type crystallizer is scrapped after a copper alloy layer with a certain thickness is worn away. The scrapped crystallizer can only be used as waste copper for treatment, so that the resource is greatly wasted, and the smelting cost of the material is also obviously improved.
In view of the above problems, the present invention provides a material increase manufacturing structure and a material increase manufacturing technology applied to a continuous casting crystallizer. According to the technology, a layer of copper alloy or copper-based composite material is manufactured on the surface of the mother material of the waste copper crystallizer in an additive manufacturing mode, so that the size of the waste copper crystallizer is restored to the original design size, higher hardness and wear resistance are given to the crystallizer, and the service life of the crystallizer is obviously prolonged. The utility model provides a be applied to copper alloy and copper base combined material vibration material disk structure and vibration material disk technique of making of continuous casting crystallizer is applicable to the special-shaped crystallizer of old and useless slab crystallizer, pipe crystallizer, roll-type crystallizer and other shapes to improve the life of crystallizer. The technology is used for remanufacturing the invalid continuous casting crystallizer parent metal with the size which is seriously lower than the design value, and the service life of the copper parent metal of the continuous casting crystallizer can be almost prolonged indefinitely. Moreover, when making the new product of the special-shaped crystallizer of slab crystallizer or pipe blank crystallizer or roll crystallizer or other shapes, reserve in advance in proper thickness in the crystallizer copper mother metal surface of making, be used for adopting the utility model provides an one deck is made to vibration material disk technique the utility model provides a copper alloy and copper base composite material vibration material disk structure layer to this is showing the life who improves the new product of crystallizer.
