Abstract

The invention discloses a method for casting a large silver alloy buddha statue by use of a gypsum mold. The method can manufacture the large silver alloy buddha statue with smooth and compact surface and vivid appearance through the steps of preparation of the gypsum mold, drying and roasting of the gypsum mold, smelting of silver alloy, casting and the like. Rare earth elements are added to enable the silver alloy material to have good chemical stability such as vulcanization resistance, smoke and dust resistance, automobile exhaust gas pollution resistance, salt-spray corrosion resistance, color change resistance and the like, and the silver alloy material also has good casting and welding performances, has wide application prospect in the aspects of jewelry, decoration, building and everyday life of people and the like, and is harmless to the environment and human body; the gypsum mold casting process is adopted to cast the large silver alloy buddha statue successfully; and the gypsum mold and the roasting process can completely meet the casting requirement of art crafts such as large complex silver ornaments and silver sculptures.

Description

technical field [0001] The invention relates to a silver alloy Buddha statue, in particular to a method for casting a large silver alloy Buddha statue by utilizing a plaster mold. Background technique [0002] Gypsum mold casting is a special casting process, which refers to a casting method of casting metal solution into a mold made of gypsum as the base material. It can cast non-ferrous metal castings with high surface precision and complex shapes. It has the advantages of easy cleaning and so on, and is often used in the mold manufacturing of non-ferrous metals. [0003] Silver is one of the first few metals discovered by humans. Silver has high reflectivity to the visible spectrum, which not only makes it white and shiny, but also has a color of special aesthetic value. Silver has excellent chemical stability and preciousness, and is easy to process into various forms of materials and utensils. These characteristics have made silver a material for making jewelry sin...
