Embodiment Construction

[0011] Prepare crucible, borax, stainless steel cooling bath, hand fan, charcoal fire. According to the mass ratio, use 100 grams of four nine pure silver materials and 15 grams of pure brass materials, put them into the crucible at the same time, put the crucible in the middle of the small stove, heat the crucible with charcoal fire, and use a hand fan after the charcoal fire is burned Blow the air, control the temperature of the crucible within 330°C, and heat the crucible slowly for 20 minutes. Then continue to heat, pay attention to observe the pure silver material of the crucible, the pure brass is burnt red and burnt thoroughly, after the red burn is thoroughly burned, use a fan to blow air, when the temperature of the crucible reaches 1250°C, the pure silver material and pure brass material will slowly melt , the melt is mixed together, at this time the temperature cannot be lowered, and it has been kept at 1250°C for sintering until all the materials in the crucible ar...

Abstract

The invention relates to a silver ornament welding rod manufacturing method which includes the specific steps: 1) preparing pure silver, pure brass and borax according to the mass ratio of 100:15:10; 2) simultaneously placing the pure silver and the pure brass into a container, and heating the pure silver and the pure brass to reach the temperature of 330 DEG C for 20 minutes; 3) increasing the temperature to 1250 DEG C and adding the borax when the pure silver and the pure brass are completely melted into liquid; 4) uniformly stirring the materials, removing impurities in the container and keeping the temperature for 25 minutes; 5) pouring melt into a tank, taking out silver ornament welding rods after the temperature in the tank is reduced to indoor temperature, and then hammering the silver ornament welding rods; 6) placing the silver ornament welding rods into a tank of a pressing purifier, pressing the silver ornament welding rods from large to small until the diameter of each silver ornament welding rod is 0.4mm by pressing. The silver ornament welding rods manufactured by the method are strong in welding surface flowability, glossy, bright, fine in quality and clear in line, and welding immobility of the silver ornament process of wire drawing, lacing, filigree and the like is improved.

Description

technical field [0001] The invention relates to a processing method for silver ornament auxiliary materials, in particular to a processing method for silver ornament welding rods. Background technique [0002] Silver jewelry electrode has excellent process performance, low melting point, good wettability and ability to fill gaps, and has the characteristics of high strength, good plasticity and excellent corrosion resistance, and has become a main auxiliary material for silver jewelry production. It is widely used in the production of various silver ornaments. However, the traditional silver-decorated welding rod is prone to uneven flow on the welding surface, slow flow speed, and the problem of "virtual welding". Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a method for making silver jewelry welding rods, so as to improve the quality of silver jewelry products. Specific steps are as follows: [0004] 1) The mass...
