Abstract

The invention relates to a composite zinc ingot die and a manufacturing method thereof, and belongs to the technical field of composites. The composite zinc ingot die is formed by covering the surface of an existing zinc ingot die with a layered ceramic particle strengthened metal-based composite, the thickness of the ceramic particle strengthened metal-based composite ranges from 2 mm to 10 mm, ceramic particles account for, by size, 40-60% of the ceramic particle strengthened metal-based composite, and the part, of the rest of size, of the ceramic particle strengthened metal-based composite is a metal matrix identical with an existing zinc ingot die metal material. Firstly, a prefabricated body is manufactured, is rapidly put in a cavity and is fixed to the inner surface of a casting die through nails; lastly, metal matrix liquid identical with the existing zinc ingot die metal material is poured into the casting die with the prefabricated body fixed, and the composite zinc ingot die is obtained after cooling is conducted. The composite zinc ingot die has good zinc liquid corrosion resisting performance and has good wear resisting performance. The manufacturing method is simple in technology and suitable for industrialized production.

Description

technical field [0001] The invention relates to a composite material zinc ingot mold and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] Zinc ingot mold is a basic tooling equipment for zinc smelting. It is used under rapid heating and rapid cooling conditions, and the temperature difference changes greatly. It is usually made of cast iron and cast steel. However, these materials have poor resistance to zinc liquid corrosion, and the zinc ingot mold is strongly corroded, resulting in a short service life and poor surface quality of the manufactured zinc ingot. Although ceramic materials have good corrosion resistance to molten zinc, their brittleness and poor impact resistance have become bottlenecks in their development and cannot be directly used for the above-mentioned parts. [0003] Chinese patent CN202137340U discloses a zinc alloy ingot mold, which is applied to the cooling process of smelting and p...
