Embodiment 1

[0030] According to the mass percentage of each component in the above-mentioned Table 1 Example 1, the raw materials are selected, and after being configured into a solution, after stirring evenly, let stand for precipitation for 60 minutes, and after standing, pass the obtained solid matter through a 200-mesh stainless steel sieve, Put the sieved solid in a drying oven, control the temperature at 135°C, and dry for 60 minutes; put the dried solid in a grinder for grinding and crushing, and then pass through a 200-mesh sieve to obtain this product. The finished product of the slag removal agent invented can be packed in bags according to different specifications according to actual needs, and stored in a dry, dark, and ventilated manner.

Embodiment 2

[0032] According to the mass percentage of each component in the above-mentioned Table 1 Example 2, the raw materials are selected, and after being configured into a solution, after stirring evenly, let stand for precipitation for 60 minutes, and after standing, pass the obtained solid matter through a 250-mesh stainless steel sieve, Put the sieved solids in a drying oven, and dry them for 60 minutes at a controlled temperature of 125°C to 130°C; put the dried solids into a grinder for grinding and crushing, and pass through 250 mesh The finished product of the slag-removing agent of the present invention can be obtained; it can be packed in bags according to different specifications according to actual needs, and stored in a dry, light-proof and ventilated manner.

Embodiment 3

[0034] According to the mass percentage of each component in the above-mentioned Table 1 Example 3, the raw materials are selected, and the following specific steps are consistent with the method in Example 1, so they are not repeated here.

Abstract

The invention discloses an antioxidation slag removal agent for the welding of metal materials, and belongs to the technical field of welding materials. The slag removal agent comprises the following components in percentage by mass: 30 to 70 percent of rare-earth additive, 5.0 to 25 percent of methoxide, 2.5 to 5.0 percent of ethyl acetate and 10 to 40 percent of cosolvent. The slag removal agent has the advantages of improving the physicochemical performance and mechanical strength of an alloy, enhancing the weldability and electrical conductivity of metals, along with a good slag removal effect, and is convenient to use.

Description

technical field [0001] The invention relates to a slag remover, in particular to an anti-oxidation slag remover for metal material welding, which belongs to the technical field of welding materials. Background technique [0002] With the rapid development of my country's national economy, tin, aluminum, copper, silver, gold and other non-ferrous metals are widely used in electronic information, aerospace, aviation and rail transportation, and high-end equipment manufacturing. However, since tin, aluminum, copper, silver, gold and other non-ferrous metals and alloys are relatively active, in the process of welding and melting, metal oxide waste slag and some waste gas will inevitably be produced, and a large amount of oxides produced will cause a large number of The loss of raw materials, which also caused a lot of economic losses. For example, the number of tin-copper alloys used in electronic lead-free solders in my country reaches more than 100,000 tons every year, and 15...
